So I decided to make a mini overpass from the trash of wood, or rather from the pieces of the board that I had left. The thing in the garage is necessary and is done in a couple of hours.
So, I think there is no need to paint a lot, everything is almost clear from the photos. The overpass turned out to be convenient and does not take up much storage space, which is also important and is made from a simple board.
The width of my board was 20 cm, so the overpass turned out to be this size.
Accordingly, at first I sawed pieces of this size, 6 pieces on each side, it turned out only 12 such blanks.
Then I drilled them through and twisted them with 12mm studs.
I did the first fitting, what distance I will have ... it turned out to be 45 clean centimeters, I think it’s not bad, just for my needs.
Then it was necessary to make stops at the ends so as not to run over the overpass 🙂
Here's what happened: 
The storage of this craft is generally cool, it takes up space purely symbolically.
this turned out to be the necessary thing in the garage, now you don’t have to grumble and substitute the jack every time, but just pick it up, drive it over and you’re done. I think someone will like this idea and have a smooth road for everyone.

DIY simple flyover - Crafts for cars
I decided to make a portable and simple flyover with my own hands. A little time and our overpass is ready, I won’t paint a lot, so everything is almost clear from the photos.
For work we need:
Welding machine - 1pc
Bulgarian - 1 piece
Roulette - 1pc
Square - 1pc
Marker (preferably white, draws well on rusty corners)) - 1 pc.
Clamp - 2 pcs
Electrodes - 2kg
Cutting discs - 4 pcs
Metal corner 50x50
Metal corner 25x25
Armature 10″
Well, let's go deeper:
The base is made from a 50 x 50 mm corner.
The base is 165 cm long, 50 cm wide and 45 cm high. It consists of two corners 165 cm and three jumpers 40 cm each.
We connect the whole thing strictly perpendicularly at the distance we need: two jumpers at the edges, they form a complete spot of the support, and the middle one at a distance of 50 cm from the extreme, so we get the support of the parking horizontal penny.
Next, we need to put perpendicularly 2 more corners already 40 cm long, we form a “stop”, the border of the flyover, so that the machine does not pass the “point of no return”. At the same time, we immediately note the parallel of the first 30 cm supports, for the subsequent horizontal connection.
Then, with a corner 117 cm long, we make a slope (115 cm long + 2 cm overlap on the nickel)
The first (concept) flyover to one side is ready. I did it without sketches and drawings, so to speak, from the head, supplementing, reworking and working through along the way. We make the second one the same ... And that's it, our flyover is ready.

Do-it-yourself mini flyover (17 photos)
Homemade mini overpass for a car with your own hands: photo, as well as manufacturing description, simple and practical overpass.
I decided to make myself a device for working under the car, a mini overpass 370 mm high.
Materials for manufacturing:
- Square pipe with a section of 50 x 50 mm wall thickness - 4 mm.
- Square tube - 40 x 40 mm wall thickness - 2 mm.
- The pipe is round - 25 mm.
- Corner 65th 5 mm.
I made the middle paws shorter than the extreme paws by about 8 millimeters so that there was no swing. When the whole mass of the machine presses on the structure, the difference is leveled. The load is distributed evenly on the thrust paws and there is no reeling.
The device has been tested.
The angle of entry is blunt, in order to drive in with a puzoter, it will be possible to weld an additional ladder, which will lie on top of the main ladder.

How to make a flyover with your own hands, for cars, from wood and metal
How to make a flyover with your own hands
In many cases, individual owners carry out maintenance and repairs themselves in various places depending on the conditions (in individual garages, in household plots, summer cottages, in open areas, along the route, etc.). In this article I will tell you how to make a flyover with your own hands for car repair.
In any case, you need to organize workplace flyovers for the production of works, taking into account the creation of the safest and most favorable conditions for their implementation. These purposes are provided by inspection ditches and tippers. Overpass inspection ditches can be made in individual garages or in open field in household, country, garden plots. To prevent the earth from crumbling, the ditch is reinforced from the inside with a brick wall or sheathed with boards. To enter the ditch make brick steps or wooden ladder. It is necessary to constantly ensure that the steps are not slippery in order to avoid falling into a ditch.
The overpass that you can make with your own hands can be metal or wooden, but its strength and rigidity should exclude the possibility of the car falling. Depending on the desire of the individual owner and local conditions, this platform for the car can be a dead end when the car enters and exits from one side, or has an independent ramp on the other side, while the total length of the overpass must be increased. The end of the dead end must have a fence to prevent the car from falling.
The edges of the ditch of the overpass for the car should rise slightly above the level of the floor, the ground (for the ditch) or the plane of the wheels in order to prevent the possibility of the car falling during installation on them or the exit (provide for safety flanges 10-15 cm high).
The length of the ditch is chosen in such a way that the car installed on the ditch in the flyover does not close entrance stairs. The width of the overpass for a car is determined by the track of the car, taking into account the safety flanges (1.0-1.1 m). The length of the horizontal part of the flyover of any kind should be such that your unit is completely installed on it.
Trestle ditch depth
The depth of the ditch and the height are determined depending on the growth of the worker so that when performing work, do not reach for the bottom of the machine or do not be under it constantly in a bent position.
In addition to the ditch or overpass, and regardless of their presence, a stable workbench or desktop must be arranged, strong and rigid enough so that a vice can be installed on it to perform plumbing work to repair individual units and assemblies.
The height of the workbench or desktop should provide a comfortable position for the worker. The width must be at least 0.75 m. The boards of the workbench or desktop must be planed cleanly, and the nails recessed to avoid injury to the hands. A workbench or work table can be upholstered with iron. In this case, there should be no sharp edges or protrusions that could cause injury.
The vise must be firmly fixed to a workbench or work bench. This is one of the conditions for preventing injury at work. hand tool. The jaws of the vise must be notched and secure the workpiece. It is necessary to fasten the part in a vice so that it does not jump out during its processing.
Lamps should be installed above the workbench or work table in the garage so that the light falls from the left side, and the illumination of the workplace using incandescent lamps with combined lighting (general and local) should be 400 lux. The actual illumination is measured with a portable lux meter. On the workbench, the tool must be stacked in a manner that is convenient for work and in such a way that it cannot fall and cause injury. The tool can be stacked on permanent shelves or hung on the walls of the garage, subject to the above conditions. We hope that our website useful tips for all occasions helped you make the flyover yourself.

how and what to make
If you do not have a viewing hole for a car, you can replace it with a flyover made with your own hands in the garage or in your country house. To do this, you will need a couple of sleepers and some thick boards or some scrap metal, a welding machine and a grinder. Of course, a pit in the garage is more convenient, but different reasons not every garage can equip it. The proximity of underground utilities or ground water, and then, if you want to repair a personal car, the way out for you will be a built overpass with your own hands.
Types of flyovers
Depending on the size, flyovers for cars are of two types:
- To access one vehicle axle.
- To enter the whole car.
Mini flyover The first category is usually collapsible and requires a small amount of material in order to make it with your own hands. It is mobile, but not as convenient for do-it-yourself car repairs as a full-size one. The inconvenience of a mini overpass lies in the fact that, due to its small height, do-it-yourself machine repair with its help is far from being full-length.
There are two types of devices that give access to the front and rear of the machine at the same time:
- Installed on level ground. Entry to their site for repair occurs at best at an angle of about 30 ° to the horizontal.
- Situated on a slope. Entrance to them occurs without lifting up (horizontally).
For those wishing to make a mini overpass for car repair with their own hands, we present the simplest design, for the repetition of which drawings are not needed.
So, to make the simplest mini flyover for a car with your own hands, you need to lay two pairs of sleepers in pairs with side surfaces to each other and connect the sleepers of each pair to each other using steel brackets. Flip them over with the staples facing down and cut one end of each pair at an angle of about 30° to the horizontal for ease of driving onto them. Lay the pairs parallel to each other, according to the gauge of your car, cut ends to one side. The portable mini flyover is ready. The height of such a structure is regulated by placing boards of suitable thickness under the rectangular ends of the sleepers. To prevent the car from rolling off the overpass, make shoes from scraps of boards and put them under the wheels when repairing. In order not to fall from the structure when entering it, attach two trimming boards to the ends of the sleepers so that they stick up a little.
To work under the car on such a flyover, be sure to get a piece of thick felt or at least an old wadded blanket. Don't leave your health on the concrete floor.
To those who say that a car can be raised to such a height with a jack, I will object that if thick bars are placed under it, then not every jack raises so much, and secondly, it is much safer than on a jack.
Full size construction
For those who do not want to endure the inconvenience when repairing their car, we offer to make a full-size version with your own hands. It will be more convenient for you to enter it if you build it on a slope. Yes, and the boards will go less. So it makes sense to look for a place on the slope for her. Of course, it is better to make a flyover from metal: it is stronger, does not absorb oil and does not rust as quickly as wood rots. But if you have a tree in stock, then the choice of material is obvious, do not buy the same rental.
metal installation
Two supports can be used. steel pipes with a diameter of at least 150 mm. They should be buried in the ground below the level of its freezing, otherwise the height of the flyover will increase with the onset of winter, and decrease in spring. After installing the supports, the pits should be rammed with broken bricks, and it is better to concrete. If the depth of soil freezing in your area is small, deepen the supports into the ground at least a meter. The height of the supports above the ground depends on your height, but should not be lower than 1.5 meters.
They should be installed at a distance of about 5 meters from the proposed entrance to the flyover, and at a distance from each other equal to the track of your car. From above, on the supports with the ribs down, lay a section of the channel about 150 mm wide, its length should be 50 cm more than the track width of your car. Weld the channel to the supports. After that, for the lateral stability of the structure, connect the supports crosswise with two corners. Lay four corners with ribs at least 7.5 cm long about 5 m in pairs parallel to each other with ribs, and fill the space between each pair with pieces of reinforcement 50 cm long and weld them to each, observing a right angle. Put the resulting ladders so that one side of each is on the edge of the channel, and the other on the ground. Check their horizontalness with a level. And also set the width between the centers of the edges lying on the ground, which should be equal to the track of your car. Weld them to the channel, and to them stops to prevent falling vehicle, and congratulations, you have welded a flyover of steel with your own hands.
Features of a wooden structure
- Instead of a pipe as supports, two pieces of timber with a section of at least 15 × 15 cm are used.
- Parts of the supports dug into the ground, for durability, must be impregnated with creosote or at least mining.
- Each ladder should be assembled from two boards 5 cm thick, one of them 10 to 15 cm wide should be placed on the edge. The other one, about 40 cm wide, is laid flat on top and nailed to the first one with a hundred nails or screwed with screws.
- In each timber, it is necessary to make one cut with a width of 5 cm and a depth in accordance with the width of the boards placed on the edge. Cuts are made in order to insert the lower boards of the ladders into them. The crossbar to the supports should not be attached from above to the ends, but in front just below the ladder board coming out of the cut.
- The stops can be made by screwing two trimming blocks to the supports with self-tapping screws, so that they stick out above the ladders.
- To reduce the likelihood of wheels slipping from the edges of the ladders, it is desirable to make ribs. One option is to attach a board about 2 cm thick and 10 cm wide to the end of the top board of the ladder. better with self-tapping screws with flat caps 50 mm long.
- Below the crossbar, for lateral stability of the support structure, it is necessary to fasten together crosswise with two boards.

Scheme of a homemade overpass (automobile):
The overpass drawings were made specifically for the VAZ car of the tenth family. Therefore, the dimensions of the overpass (the distance between the lanes and the length) for other vehicles may differ.
For the construction of the flyover you will need:
|
The overpass device is quite simple, and if you have the necessary tools (angle grinder, welding machine), it will not cause difficulties in manufacturing. The design of the flyover is collapsible, which allows you to assemble it for a partial arrival of a car:
For full arrival of the car:
And when disassembled, the flyover can be easily placed in the garage, on the side, without interfering with the car. The overpass is metal, so its reliability is beyond doubt. The overpass is mounted using 12 M14 bolts. The overpass can be installed on almost any surface (smooth and uneven).
By the way, despite the simplicity of design, manufacturing mobile overpass It will take about a week of working time.
By the way, during this time you can perform most car soundproofing.

Make a flyover with your own hands |
Photo source:
A viewing hole is needed by almost any motorist. With its help, you can make a scheduled inspection of the car and its partial repair. Such a structure is especially important if there are no maintenance stations nearby.
What is the design for?
As already mentioned, if you have a car, then there may be certain problems with the mechanisms. Not all breakdowns can be fixed right in the garage. Sometimes you have to climb under the car. Naturally, doing repairs lying down is not very convenient. That's what the overpass was designed for.
It is not difficult to make such a structure with your own hands. You just need to decide on the design and assemble everything necessary materials. It should be noted that for the construction of the structure, you can use everything that is on your farm. For example, an overpass for car repair can be made of metal stairs (aerial version), bricks, or simply dug in the form of a hole (underground version).
What tools might be needed?
To construct such a structure is quite simple. You must first draw a diagram on paper, calculate its dimensions, and also select the necessary tool:
- Welding (if a metal version is built).
- Bulgarian (for cutting materials).
- Shovel (if you want to make a hole or fix above-ground racks).
- Brick and sleepers.
- Cement (so that the product does not “ride”, it should be fixed concrete mortar).
From this list, you choose what you will need depending on the materials.
How to make the simplest version of the design?
It is a structure on which the car can only drive the rear or only the front wheels. Such a flyover for a car consists of the same structures that can be made of metal or wood. Please note that the width of such products should not be less than 40 cm. Otherwise, they may be unstable or too narrow.
You can weld this design from the corners. In this case, the cross section of the elements is about 2.5 cm. In order for the car not to slip off the overpass, limiters must be fixed on the racks. Their height is at least 7 cm. After all welding work will be completed sharp corners must be removed with a grinder. In order for the product to last as long as possible, it must be coated with a special anti-corrosion compound or painted. Please note that one element of such a structure will have a fairly large weight.
How to make a structure from stairs?
Such a flyover with your own hands is also done quite quickly. It is a more advanced version than the previous one. You will need two to work. metal stairs at least 3 meters long, welding machine and corners.
First you need to process all the components with an anti-corrosion compound. Further, 4 vertical supports must be welded to the edges of the stairs, on which they will stand (like benches). Their length should be sufficient so that it can be partially dug into the ground. Naturally, in this case it is better to choose corners or pipes. In any case, these elements must be strong enough to support the weight of the vehicle.
After the main structure is assembled, it is necessary to fix it in the garage. Place the future overpass so that it is convenient for you to drive onto it. Racks in the ground must be fixed with concrete mortar. In order for the car to drive onto the structure, 4 more corners must be welded to the stairs at an angle (on both sides). Between themselves, it is better to combine them with crossbars.
Features of the arrangement of the viewing hole
The construction of a flyover of this type is the most common. However, it is possible under one condition: you have a lot of free space. Such a viewing hole should have a depth of at least 1 meter. This parameter depends on the height of the person who will be repairing or inspecting the car. To prevent the earth from crumbling inside, it is better to sheathe the walls of the structure with boards. In order to descend into the pit was convenient, you need to either dig steps or put up a ladder. Please note that steps should be equipped with anti-slip pads.
Please note that the edges of such a flyover should be slightly above ground level. The length of the pit must match the size of the machine. At the same time, after arrival, the car should not block the stairs for descent. As for the width of the ditch, it is about 1 meter. Safety flanges must be added to this distance.
As you can see, do-it-yourself overpass is being built quite quickly. You just need to draw a diagram in advance and select materials.
Overpass arrangement
Naturally, the workplace must be appropriately equipped. For example, there should be a workbench nearby with all necessary tools. Everything that will be needed for repairs should be at arm's length.
You will also need to organize good lighting. It is better to use LED or fluorescent lamps. Inside the inspection pit, you can make additional shelves on which the tools will be placed. Please note that they must be fixed as well as possible, and at a level so that in the event of a fall of any products, they cannot harm you.
The inside of the hole can be lined with bricks. Better build a foundation. The surface on which the car will stand should also be fixed as much as possible. It is better to install it on pipes dug into the ground to a great depth.
If you need a flyover, with your own hands you can make it in just one day.
The overpass replaces the viewing hole. Its presence allows you to carry out technical inspection and minor repairs of the machine yourself.
Depending on the type of the car itself, its size and the size of the overpass itself, its type is determined. You can make both stationary and collapsible. How to make a flyover for a car with your own hands is easy to learn.
Process of creation
1. First you need to decide on the type of flyover. If the size of the garage or suburban area allow, then you can make stationary.
2. The collapsible version is suitable for those motorists who are limited by certain parameters.
3. A complete inspection of the car is available only on a stationary overpass.
4. Partial can be carried out on a collapsible overpass.
5. Before selling a car, it is still better to entrust the inspection to specialists, for example, from.
The stationary overpass is made of bricks, wood, metal pipes. It can rise up to a meter above the ground.
To create a stationary metal overpass, you will need tools such as:
- welding machine;
- Bulgarian;
- fasteners;
- dye.
Basic Steps
- The overpass can be made using pipes that must be concreted into the ground. You will get 4 or 6 columns.
- Corners are installed over the pipes.
- between them with welding machine rebars are installed.
- Check-in is obliquely fixed.
- The places for the wheels must have stops that will not allow the car to move off on its own.
- The metal structure must be covered with anti-corrosion paint so that nothing rusts.
If there is no place for such a design, then it makes sense to learn how to make a simple overpass for a car.
There are several options for small collapsible structures:
- one-sided pyramid;
- "rocking chair";
- flip;
- from sleepers.
The very first type is made of boards and beams in such a way that one end is a plane and the other is a ladder. The boards are cut into equal parts about 30 cm long. The bars are cut into parts of different lengths, boards will be attached to them from above. Between themselves, both pyramids are fastened with metal rails so that they do not part.
A "rocking chair" can be made by almost any motorist. To do this, you will need two boards on which bars are installed at the edge and closer to the middle, but with an offset to the edge. When a car drives onto a structure, its center of gravity shifts and it is raised.
How to make a flyover for a car based on sleepers is very simple, just lay two sleepers that continue each other, boards are placed on them, which are a platform.
This building with your own hands can be built from almost all improvised materials.
Boards can be rested anywhere, so the question of how to make a flyover for a car yourself should not cause difficulties.
by the most affordable option will become: place a sawn piece of log of the desired height on the board, fix another board on it at an angle, fix everything - half of the structure is ready. The second half is done in the same way.
There are flyovers made of bricks, but they cannot be moved from place to place, so they are stationary.
All dimensions must match the specific vehicle. It is best if the width of the race is slightly larger than the size of the wheel. This will eliminate the risk of a “miss” and damage to the vehicle. Be sure to have stops for the car so that it does not move off the platform.
It is not difficult to make a flyover for car repair with your own hands if you have free time and minimal technical skills. All measurements must be carried out carefully so that the flyover is suitable for a specific car.
Flyover - indispensable tool for inspection and repair passenger car. A small mini-design is made at home with my own hands. It is important to observe all dimensions and focus on the dimensions of your car.
The need to install a mini-flyover. Device
A modern car is a technically complex device that requires periodic Maintenance, replacement of components and consumables, minor repairs. Many inexperienced motorists prefer to conduct a routine inspection of the car exclusively at the service station and pay out of pocket even for an oil change.
More experienced drivers do most of the work with their own hands. To do this, a makeshift flyover is often installed in the garage - a structure with which you can explore the bottom of the car.
Overpasses are of two types:
In the first approximation, the functions of the flyover are similar viewing hole. It provides access to the bottom of the car. However, when high level groundwater at the construction site of the garage, it is not advisable to equip a viewing hole: it will be constantly flooded with water, which will require the equipment of an additional drainage system, and corrosion will appear on the metal parts of the car due to increased moisture.
A full-length overpass is a monolithic structure that can be found in auto repair shops and along busy highways. Its installation requires a lot of space - the length of the product is about six meters above the ground plus a ride. The construction of such an option in your own private garage is justified if the building is designed for two parking spaces, one of which is empty.
Mini flyover - small portable design designed for partial collision with a car. It is based on two independent parts that are not connected to each other. The car runs onto the prepared platform with its rear or front wheels, rises slightly above the floor or the ground and allows the car owner to carry out an initial inspection or cosmetic repairs.
The advantage of a mini-overpass is the possibility of its use in a limited space. After work, it can be removed to the side. The main disadvantages of the design are as follows:
- Jeweler's precision is required to enter the platform. Otherwise, the structure may tip over or the vehicle may be damaged.
- Structural elements are installed in places where the possibility is excluded that they will disperse in different directions from the slightest push of the wheels.
General requirements
In the manufacture of a standard overpass, a number of requirements must be observed. This will help ensure convenient and safe work with a car.
- The height of the full-size repair structure is about a meter. This allows you to freely climb under the car, provide a sufficient influx of natural light to inspect the chassis, and carry out the necessary manipulations with spare parts and tools. The height of the mini-flyover with a partial arrival is about half a meter: it does not involve a detailed disassembly of the car.
- The width of the structure directly depends on the type and dimensions of the vehicle. You should not display the size to the millimeter, when calculating the design, you need to make small allowances. The car must be free to drive onto the platform.
- Mini flyovers are used for inspection and repair of passenger cars. For a stationary structure, an additional margin of safety is provided. Due to this, the product does not deform over time. It can also be rolled up and quite heavy transport.
Material selection
There are many ways to make a flyover or mini-flyover for car repair with your own hands.
brick construction
Overpass made of bricks - fixed structure, which is more often used in rural areas or outside the city. The construction is carried out using the brick masonry method. cement mortar. The width of the structure corresponds to the distance between the wheels of the car.
This method has several disadvantages:
- It is necessary to allocate a piece of land for development. If the overpass subsequently needs to be removed, its dismantling will require considerable effort and time.
- After some time under the influence of overloads brickwork may be destroyed, as a result of which it may be necessary to dismantle it.
Overpass of sleepers
The structure is based on several railway sleepers. Sleepers stacked one on top of the other in a “slide” style form two bases. Tracks are laid across to ensure the check-in. To prevent the overpass from the sleepers from moving apart during operation, it is carefully fastened with brackets.
This design also has certain disadvantages.
- Sleepers in everyday life are not so common, and not every car owner has a few extra ones.
- It is impossible to install and disassemble such an installation alone. The sleepers are too heavy.
- Storage of railway sleepers requires space.
The use of a flyover made of railway sleepers is justified on a country or garden plot when the structure is left on outdoors all year round. To protect against decay, the product is impregnated with creosote.
metal
Most often, the overpass is made of metal and wooden planks. Advantages of a metal overpass:
- Mobility. If desired, the structure can be made collapsible and assembled only before the start of the repair. This saves space.
- Simplicity of design. You can assemble a metal overpass with your own hands using a minimum of tools.
- Durability. With proper care and timely inspection, a metal overpass can last about ten years or more.
There are also some disadvantages. The metal is initially susceptible to corrosion, therefore, before work, the material must be treated with special impregnations.
Among the main advantages of a wooden overpass, one can note the ease of assembly and the low cost of materials. It is easy to install and, if necessary, can be quickly dismantled and removed. You do not need complex specialized equipment, just ordinary carpentry tools that are in every home. Among the shortcomings wooden structure low durability, low resistance to decay and insects can be noted. Partially, these problems can be solved with the help of treatment with antiseptics, fire retardants and insecticides.
Tools and materials
Independent production of a wooden or metal flyover requires certain materials and tools. There is no need to purchase complex specialized equipment, it is enough to purchase household power tools that are sold in every store.
What is needed for the construction of a metal overpass
For the manufacture of a conventional metal overpass, you will need the following materials and tools:
- Rolled metal.
- Welding machine with a set of electrodes.
- Bulgarian, equipped with several cutting wheels.
- Reinforcement pieces.
- Fasteners: bolts, nuts.
- Paint for metal for the final processing of the structure.
Materials and tools for a wooden flyover
For the manufacture of the simplest portable wooden overpass, a minimum of materials and tools will be required:
- Boards 45–50 mm thick. If thinner boards are used, additional vertical supports are installed in the center of the flyover.
- Two wooden blocks.
- Two pieces of wagon board.
- Screws (150), nails (300), screwdrivers, hammer, wood saw.
Preparation for work and drawing up a drawing
Before making a flyover, it is necessary to carry out a number of measuring works. The mini-flyover consists of two independent units. The width of each of them corresponds to the wheel of a car with a small margin. The interval between settings is equal to the distance between the wheels of the car. At the same stage, tools, materials and a place of work are prepared.
All dimensions are approximate and calculated for each car model.
Do-it-yourself metal structure
If a metal overpass is planned to be used in several places, or it is only needed occasionally, the structure can be made in a collapsible version. This will allow you to quickly collect it as needed within half an hour.
The assembly of the metal overpass is as follows:
- The bases of the pedestals are assembled. The blanks are cut based on the size of the wheels of the car. The blanks can be divided into chipboard sheet or other flat surface and fix at an angle of 90 degrees (you can use a regular building corner to determine the angle). After all measurements, the workpieces are welded together.
All parts are connected at right angles
- Racks are assembled. The height is about half a meter, the angle is about 120 degrees. Fixed, scalded.
Corners and side walls must be equal
- The top supports of the pedestals are welded. To do this, the upper corners are connected to the racks, set at an angle of 90 degrees, and scalded.
- Finished supports are connected to the base, set at a right angle and welded.
After assembly, you can additionally go through welding on the main nodes
- The dead end of the curbstone is welded. This is necessary so that the car does not go further and does not roll over. The part is made from a corner 63 * 63 * 5 mm.
- Reinforcing beams are welded to the finished pedestal. To adjust the distance between them, you can use the same corner 63 * 63 * 5 mm. Reinforcement segments are stacked so that their "herringbones" intersect.
A regular building corner with a side of 63 millimeters is used as a template
- Assembly of ladders (bridges). Blanks are cut, fixed with clamps at the corners. Rebar cuts are welded to the corners, the distance can be determined by the template corner, the “Christmas trees” cross. The corners are welded to the workpieces.
On these bridges, the car will drive onto the overpass
- The final step is fitting. On flat terrain, both parts of the flyover are set close to each other. The centers of the pedestals are marked, the design is set to the width of the car. Holes are drilled in the ladders and pedestals, after which the elements are interconnected with bolts. Thanks to the bolted connection, it will later be easy to disassemble and assemble the flyover.
The finished structure is cleaned with a metal brush, degreased and painted.
The finished design will look something like this
Making a wooden mini-flyover
Protozoa wooden overpass assembled from two pairs wooden beams with a section of 20–20 cm. The bars are knocked down in pairs, cut at an oblique angle. The improvised overpass is ready.
An improved wooden overpass is assembled from scraps of boards, which are knocked down into a wide “pyramid shield”. On one side, a stepped slope is formed for the arrival of a car.
Another version of the mini-flyover is assembled from four 50-mm boards, two blocks, lining and fasteners.
A similar design is used for the repair of passenger cars. For heavy transport, it is worth installing a stationary overpass.

Each car owner can independently make a mini-flyover. It is very important to check the strength of the structure before driving a car onto it and starting repair work.
If you are the owner of your car and garage, while you prefer to at least occasionally look under your car yourself, then the following is for you. Usually, inexperienced drivers prefer to carry out inspections only at service stations and give their hard-earned money to "specialists", but even minor work on changing oil, consumables, monitoring the condition of your car's units and mechanisms can save your budget. A flyover made in the garage with your own hands is the best way out of this situation.
Let's look at the statistics of the survey on whether it is difficult to make a flyover in the garage with your own hands. 66% of respondents answered that it is quite simple; 14% think it's simple, but with minor problems; 16% said it is not easy and skills in this area will be required; for 4% this is a very difficult task.
Depending on the size of the garage and the model of the car, you can choose a flyover option that will meet your needs.
Overpasses can be divided into 2 types:
- for full arrival of the car;
- for partial lifting of the car.
The first type will provide more comfortable conditions car maintenance work than the second.
Overpass options for full vehicle arrival
Such a statement would be correct in terms of the meaning of the word. But the function of the pit is the same as that of the overpass - to provide access to the bottom of the car.
The advantage of the pit is that it will not occupy the useful space of the garage.
If the groundwater level in the area where your garage is located is high, then it is not advisable to consider the issue of a viewing hole.
Otherwise, you will have to do extra drainage system(which is very troublesome and expensive), and the bottom of your car will be subject to constant corrosion due to moisture that will collect in the pit.
As a result, you will have to fall asleep and consider other options.
brick flyover
This option is suitable for those who have a garage located in the countryside or in the country. This design is carried out by the usual laying of bricks on cement mortar - along the width of the distance between the wheels of the car in the form of a trapezoid.
The disadvantages of this type of overpass are obvious: a site is needed for its construction; brick can collapse over time; if it is necessary to free the site, then the dismantling of the structure will require considerable effort and time from you.
Overpass of railway sleepers
Such an overpass is assembled from several railway sleepers, like a children's designer.
You can lay out 2 bases by laying the sleepers one on top of the other in the form of a slide. Across lay the track for the race.
To prevent the structure from moving apart during the repair of your car, it must be fastened with brackets. The disadvantages of this overpass are obvious.
Firstly, not everyone has sleepers in stock. Secondly, the sleepers are very heavy, it will not be possible to assemble and disassemble such a structure alone. Thirdly, after completing the automobile repair work need a lot of storage space for sleepers.
Of course, if you are building this design in the garden, you can leave them in the open. The sleepers are usually impregnated with creosote, which prevents the wood from rotting.
Metal variant
If the previous options are possible subject to availability land plot, then the metal overpass can be considered as a universal one - it can also be used in urban conditions.
For its manufacture, you will need the following tools and materials:
- rolled metal products;
- welding machine;
- fittings;
- grinder with cutting wheels;
- bolts with nuts;
- metal paint.
If desired, you can make the overpass collapsible. This will save space by quickly assembling it if necessary.
Its design is quite simple. It is necessary to assemble 4 base racks approximately 50 cm high. To ensure stability, it is better to assemble the sides in the shape of a trapezoid and connect them with crossbars of the same length.
For this, a 63 corner (5 mm thick) is suitable. For the manufacture of bridges, you can use a 40 corner (thickness 4 mm) and reinforcement (12 mm is suitable).
The bridges are a metal ladder. It will be necessary to make 2 bridges for arrival and 2 bridges on which the car will stand during the repair. You can calculate the minimum length of the latter yourself by measuring the distance between the centers of the wheels of your car and adding a small allowance.
After individual elements will be ready, it is necessary to fasten them with bolts. In order to provide additional rigidity to the entire structure, you can combine the racks with each other. A bolted connection will allow you to assemble or disassemble the entire structure in a short time.
Garage flyover device
With a complete shortage of space, a way out of the situation can be found in the manufacture of mini-flyovers. They belong to overpasses for partial lifting of the car. Of course, working in this case will be less comfortable than with the options discussed above, but much more convenient than under a car raised by a jack.
Several options for mini-flyovers
The most elementary version of a mini-overpass can be made of wood.
To do this, you need a board (you can take a thickness of 50 mm), which is wider than the wheels, and wooden lath square section (for example, 100x100 mm). The height of the cross section will determine how high the car can rise. With the settings recommended above wooden products lift height will be 150 mm.
The structure is assembled as follows.
- A bar is attached to the back of the board from above, which will perform the function of limiting the wheel travel. 2 square bars are attached to the bottom part: one is a little further than the middle, the second is on the edge of the board. The structure is ready.
- You need at least 2 such devices (or 4 if you need to raise the entire car above the ground). Such a mini-overpass works very simply. When you put the structure under the wheel of your car, it rests on the ground at 2 points: the front edge of the board and a bar, which is fixed not far from the middle.
- As the wheels of the car hit the board and the center of gravity moves closer to the rear edge of the board, the front edge will rise and the rear edge will drop. Since the supports were made of a bar with the same section, the board will take a horizontal position.
- At the same time, the length of the board should be such that it does not hit the bottom of your car. It remains to fix the wheels that remained on the ground with stops-blocks. As you can see, such a flyover is very easy to make with your own hands. You can make a mini-flyover from metal. Its design will resemble the metal overpass discussed above, only in a smaller version. It also consists of supports on which bridges are attached.
- It is desirable to weld limiters along the edges of the bridges. This will keep your car from slipping.
- One bridge is located at an angle from the ground for arrival, the other is horizontal (when viewed from the side of the structure, the contour will be a trapezoid). You can focus on the following dimensions: base length - 80 cm; the length for the race is about 45 cm, the width of the bridges is about 40 cm. The entire structure can be assembled from a 25 mm corner (less is not recommended). The approximate weight of the structure will be 20-30 kg. At the rear, a travel stop for the wheel must be welded.
A more complex, but effective version of a mini-flyover can be made according to the swing-rocking principle. For its assembly will require welding work. It will be necessary to make 2 frames in the shape of an isosceles triangle. The width of the frames is selected depending on the width of the wheels of your car, and the length of the bridge - depending on the length of the car.
To ensure the rigidity of the frame structure, it is necessary to fasten it together. For the stability of the structure, it is necessary to use spacers under the side that will be above the ground. In this case, it should be borne in mind that for greater stability, the center of gravity of the car should be closer to the top of the isosceles triangle.
When working on overpasses, you should always remember to observe safety measures. The car must be put on the hand brake, fix the wheels with blocks-stops.
Let's summarize. Have you considered various options and approaches on how to make a flyover with your own hands. Depending on the free space you have at your disposal, materials, finances and desire, you can choose any option for your garage.
It can be both a solid structure and a collapsible version of a metal overpass. It may be enough for you to make a wooden mini-flyover. In any case, the choice will be yours.
