Do-it-yourself overpass for car repair

In detail: do-it-yourself car repair flyover from a real master for the site my.housecope.com.

We want to be able to understand and repair everything, so as not to attract outsiders and not pay for this funds, which are not so easy to get now. Someone delves into the device of various mechanisms just for the sake of a hobby. And for those, and for others, information on how to build an overpass in the garage with your own hands will be relevant.

Observation pits are very popular and widespread. They are relevant for garages with low ceilings, where there is no way to raise the car. In some areas, the groundwater is close enough to the surface that a thorough waterproofing should be done so that the inspection of the vehicle does not turn into taking a cold bath. If this is true for you as well, or you simply don’t want to mess around in order to spend energy on excavation, then the flyover will be the perfect solution.

There are two main types of flyovers:

stationary;
collapsible or mini-overpass.

Many of us have seen stationary overpasses - they can be located on the sides of some sections of the road, so that a driver experiencing technical problems can put in order or temporarily fix a car malfunction. It is not difficult to make such a structure at home. The main requirement will be the availability of sufficient space. If your garage is designed for two vehicles, then a platform can be erected in place of one of them. From materials you can use bricks, floor slabs, wooden beams, metal channel and pipes. The most durable and durable metal structure will be.

Note! With the correct overpass construction and calculations, you can lift your car almost a meter above the ground.

You will need pipes with a total length of up to 2 m. Approximately 1 m will have to be sunk into the ground and securely concreted. You will need from 4 to 6 such posts, it all depends on the size of the machine. From above, four corners measuring 7.5 by 7.5 cm are fixed, the space between them is filled with rods from reinforcement, which are welded perpendicularly. In the same way, the race is set at an angle. It is imperative that the design must provide for limiters that will not allow the car to roll back or drive further forward. The length is tailored to your specific needs.

But not all of us have two cars or large garages in which you can play football or have a party, so you should pay attention to mini overpasses, which can be collapsible or move freely around the territory, and stored in a garage or shed. You will need some ingenuity to make them. Here are some options to choose from:

A similar truncated pyramid or trapezoid can be made from a metal channel, it will turn out to be much more reliable and durable. Instead of climbing a "ladder", you just need to make an inclined drive.

Note! With the help of such a device, the car can be raised by 30 cm, if a greater height is needed, add a few more planks of greater length. Remember to install restraints at the front to prevent the vehicle from rolling forward, and secure the rear wheels as well.

"Rocking chair" is also a very simple design that any car owner can make. Two boards are selected as thick as in the previous example, the length can be 1 m.We take four blocks 10 × 10 × 30 cm and place them as follows: one of them is on one of the edges, the second is almost in the middle with an offset to the first. We fix it firmly and do not forget to focus. Now, when the car runs over with the wheels, the boards will be thrown over due to the displacement of the center of gravity, with further advance they get an emphasis on two bars. Everything! The machine is lifted! Repairs can be made. You can vary the dimensions based on the ground clearance of a particular vehicle and the length of the wheelbase.

There is another version of this flyover, it is a little more complicated in execution, but much more reliable. The designs may vary. Here is one of them. Take a corner 30 × 30, as much as possible, adjust the length, focusing on your car. We need 8 such segments. We connect them in parallel using crossbeams. The result should be 4 bases of the same size. The bottoms can be made longer and wider for greater stability. Then we make two stops. One of them will be in the form of a bar, as in the previous example, we weld it to the edge. Set the second one with a slight offset from the middle. But it should be made a little differently - in the shape of an isosceles triangle. We move it to the bottom base. If you do not touch the stands, they will be folded at an angle. When the car moves along them, the wheel shifts the center, aligning the horizontal, and abuts against the block. Now the latches can be used to fix the platforms in this position.

Using a platform is an interesting approach to business. To make it, you need to get a corner that we already love, or use a square profile. Further, with the help of a welding machine, 2 isosceles triangles are made so that the base is 1.5 times longer than the wheelbase in length, and the vertex angle is obtuse. The platform rests on them. Now everything is ready. The car drives into the structure and, resting on the limiters, reaches the end.

Note! Place supports under the rear wheels so that the car does not roll when it is on the overpass.

The overpass on the basis of sleepers is very simple to make. Two sleepers are stacked, one in continuation of the other. Strong boards are laid on the part with a recess, after which a small slide is obtained. That's it - the platform is ready, you can call in and be repaired. The disadvantage is that the sleepers need to be stored somewhere, although it is unlikely that someone decides to take them away from you. For this kind of platform, it is not necessary to use sleepers, everything will do that you can reliably rest the boards on.

Note! When constructing a makeshift overpass, do not forget to protect your car by installing restraints - they will prevent the car from falling off the overpass.

As you can see, there is no particular difficulty in lifting the machine for service. Now you know how to make a flyover from scrap materials that are found in almost every garage. Tell your friends and share your experience.

The video shows a homemade rocking platform for carrying out maintenance and repair work on it:

Watch a video about a homemade metal overpass for a car:

I decided to make a portable and simple flyover with my own hands. A little time and our flyover is ready, I will not paint a lot, so everything from the photos is almost clear.For work we need:Welding machine - 1 piece
Bulgarian - 1pc
Roulette - 1pc
Square - 1pc
Marker (preferably white, draws well on rusty corners)) - 1pc
Clamp - 2pcs
Electrodes - 2kg
Cutting discs - 4pcs
Metal corner 50x50
Metal corner 25x25
Rebar 10 ″Well let's go deeper:
The base is made of a 50 x 50 mm corner. Image - Do-it-yourself overpass for auto repair

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 lintels at the edges, they form a full support spot, and the middle one at a distance of 50 cm from the extreme one, so we get a support for a parking horizontal penny.

2.Pyatak parking.
Next, we need to raise the perpendicular relative to our base, we do this with two corners (all the same 50 x 50) 30 cm long, thereby outlining the border of the parking penny.

Next, we need to put 2 more corners already 40 cm long perpendicularly, we form a "stop", the border of the overpass, so that the machine does not pass the "point of no return". At the same time, we immediately mark the parallel of the first 30 centimeter supports, for the subsequent horizontal connection.

Then, with a corner 117 cm long, we make a slope (115 cm long + 2 cm overlap on a penny)

The first (concept) one-sided overpass is ready. I did it without sketches and drawings, so to speak from my head, supplementing, altering and working on along the way. The second one is doing the same ... And that's it, our flyover is ready.

The landscaping of the personal plot can be considered complete if an overpass for car repairs is independently built for the "complete set". The dizzying designs of flyovers are striking in their laconicism and the ability to use the simplest rolled metal products. Do you dream of making an overpass with your own hands? What could be more fun!

Almost every homeowner dreams of seeing his or her own garden plot attractive, practical and functional. And if the homeowner is also a passionate car enthusiast, then you simply cannot do without an overpass designed to repair cars on the site.

Even if you do not plan to service the car yourself, a periodic technical inspection will help you identify troubles in a timely manner and contact a professional workshop. To access the car, use special lifts, a viewing pit and an overpass. However, expensive special equipment and a viewing hole equipped in accordance with all the rules are purely the prerogative of service centers, which requires significant material costs.

An overpass for a car, on the other hand, can be installed anywhere on the site, almost next to the potato beds, and mind you, with your own hands. It is possible to make an overpass for a car for cars and trucks. The area of use and application of such an overpass can be expanded and it will be possible to use the services of a "personal car service" at any time of the day or year.

Structurally, the following types of overpasses are distinguished:
• for partial arrival of a car
• full-size overpass.

Naturally, depending on the dimensions of the structure of the overpasses and the load-bearing capacity, these types of overpasses are used for a certain weight of vehicles. The only condition will be to limit the size of the overpass for your existing car or two.
The classic design of the overpass (practically according to the driving instructor) has a certain height, width and length of the working part, limited by the bevel, as well as on the sides of the walkway.

The overpass for partial arrival of a car (portable and mini) is a lightweight portable structure consisting of separate parts that are not welded together. Portable and mini flyovers are installed without a foundation. Driving to this overpass for the subsequent technical inspection of the car is possible with front or rear wheels.

Such an overpass for a car is simply installed and also easily removed, allowing you to save space on the site. However, for a successful arrival at the structure, the dexterity and dexterity of the driver will be required.
The main parameters of the overpass:
• height - not less than 1 m.
• width - 2.5 m.
• bevel length - 4.2 m.
Structurally, a portable or mini overpass consists of four parts.

The overpass is easily assembled and disassembled, as well as transported to the required place, therefore, for a sudden diagnosis of a capricious car, such an overpass is indispensable, especially in "field conditions". In practice, it is sometimes necessary to make two overpasses in order to raise the front or rear of the car to the required height (ground clearance plus overpass height).

This is how a self-made flyover looks like, used for a partial drive.

Of course, a full-size overpass is a more convenient and reliable structure, for the construction of which a working space is required. But the full-size overpass will more than recoup the costs of its construction in the future.The main parameters of a full-size overpass are similar to the parameters of portable and mini overpasses:
• height - 1 m and more
• width up to 2.5 m.
• length of the working part - 4-6 m.
• length of bevels on both sides - 4.2 m.
Let's make a reservation right away that the dimensions of a full-size overpass for passenger cars are not constant.Therefore, a full-size overpass is made taking into account the safety factor and additional allowances, which will play a good service in the future. In addition, a full-size flyover can be successfully used as an observation overpass for a car by equipping an inspection pit.Theoretically, you can make an overpass for a car from any material at hand. Planks, bricks and used tires are used. But such temporary measures can only be justified in extreme cases.Therefore, for the main load-bearing elements and overpass tracks, rolled metal products are used that can withstand significant daily loads. This is a metal channel, corners and a profile pipe. These types of rolled metal can withstand significant bending loads. Image - Do-it-yourself overpass for auto repair

For the manufacture of a mini overpass, the following materials will be required:
• steel corner, thickness not less than 10 mm
• metal bar.
as well as electrodes for welding and a welding machine. We choose the shape of the supports for the mini overpass "trapezoid", with the base 15-20 cm larger than the upper part. A ladder for arrival is made of steel corners, onto which pieces of a bar are evenly welded on both sides.

It is preferable to choose the surface of the bar grooved so that the wheels of the car do not slip when going up and down the overpass.

The load-bearing elements of the overpass, on which the ladder is attached, must have a width of 45-50 cm. The car is fixed by special gaskets, which exclude the spontaneous departure of the car. After welding, the structure of the overpass is painted with anti-corrosion paint.

A mini overpass for car repairs is presented in this video.

Initially, a site is selected on the site where there are no soil swelling, groundwater and soils do not have a water-saturated layer. Pits are prepared for the base of the overpass - pillars or steel pipes, up to 10 cm in diameter. Image - Do-it-yourself overpass for auto repair

The number of pipes for the base of a full-size overpass is calculated according to a preliminary working sketch. Pits with installed pipes are cemented. A channel is welded to the installed pipes or posts to enhance the bearing capacity.
It is also recommended to use rolled metal products (channels, corners and shaped pipes) as load-bearing elements for the tracks. Then a rolling plane is made: reinforcement and cut rods are welded across the bearing elements on both sides.

The width of the raceway of the rolling plane must be at least 0.5 m. The resulting welded structure is placed on special supports of the required height (1 meter). For the manufacture of a platform for arrival and stairs, an L 50 corner, welded with fittings, is used. It is preferable to enclose the edges of the tracks with a corner to prevent the car from slipping.

Dear visitors of the site “Self-made friend»The presented material will show you how to make a mini-flyover yourself to repair your car in the garage. Car owners are well aware that during operation it is often necessary to repair the car and carry out an inspection, it is best to do this in a warm and well-lit garage with a viewing hole. But often modern garages do not have one, because there is a huge number of various car services and workshops. This is certainly good, but you will have to pay for the services, and the cost of a car is already affordable today. So in order to save money and repair the car yourself, you need to make a mini-flyover. The base will be a 50x50 mm corner, reinforcement crossbars of 12 mm with a step of 75 mm.

This overpass is installed on the track width of the car and driven onto it by the front or rear wheels. Attention! When installing a car on an overpass, be sure to put it on the handbrake, and put a hauler or stop under the wheel.

Step-by-step instructions for making a mini-overpass with your own hands.

And so, first of all, let's take a look at the detailed drawing that the author compiled.

Further, according to the dimensions of the drawing, this structure was welded, for which an angle of 50x50 mm and reinforcement of 12 mm were used.

The second part is made in the same way.

Then the product is painted bright yellow.

After the paint dries, you can test

This mini flyover is very convenient to store in the garage.

It is so compact that it can be stored even at home.

Thus, a very convenient and compact overpass has turned out. Guys, how do you like this idea? Your opinion on the presented homemade product is important. Thank you very much for your attention!

The overpass is an indispensable tool for the inspection and repair of a passenger car. A small mini-structure is made at home with your own hands. It is important to respect all dimensions and be guided by the dimensions of your car.

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 a service station and pay out of their own pocket even for an oil change.

More experienced drivers do most of the work with their own hands. To do this, a home-made flyover is often installed in the garage - a structure with which you can explore the bottom of a car.

Overpasses are of two types:

Fullsize. Driving into this structure, the car rises above the ground by about a meter. You can examine the bottom, the hood, carry out the necessary manipulations. Suitable for servicing cars and light trucks
Mini flyovers. Provides partial lifting of the vehicle. This is enough for making a do-it-yourself car cosmetic repair. Suitable for partial arrival of passenger cars

In the first approximation, the functions of the overpass are similar to the inspection pit. It provides access to the underbody of the vehicle. However, with a high level of groundwater at the construction site of the garage, it is impractical to equip an inspection pit: 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-size flyover is a monolithic structure found in auto repair shops and along busy highways. To install it, a lot of space is required - the length of the product is about six meters above the ground, plus a drive-in.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-overpass is a small portable structure designed for partial collision of a car. It is based on two independent parts that are not connected with each other. The car runs into the prepared platform with rear or front wheels, rises slightly above the floor or the ground and allows the car owner to conduct an initial inspection or cosmetic repairs.

The advantage of a mini-flyover is the ability to use it in a confined space. After work, it can be removed to the side. The main disadvantages of the design are as follows:

Jewelry accuracy is required to enter the platform. Otherwise, the structure may overturn or damage the car.
The structural elements are installed in places where it is excluded the possibility that they will disperse in different directions from the slightest push from the wheels.

When manufacturing a standard overpass, a number of requirements must be observed. This will help to ensure comfortable and safe work with the car.

The height of the full-size repair structure is about one meter. This allows you to easily climb under the car, provide a sufficient flow 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 drive-in is about half a meter: it does not imply 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 up to a millimeter; when calculating the structure, you need to make small allowances. The car must freely enter the platform.
Mini-flyovers are used for inspection and repair of passenger cars. An additional margin of safety is provided for a stationary structure. Thanks to this, the product does not deform over time. Also, you can roll up quite heavy vehicles on it.

There are many ways to make a do-it-yourself flyover or mini flyover for car repairs.

A brick overpass is a stationary structure, which is more often used in rural areas or outside the city. The construction is carried out by the method of brickwork with cement mortar. The width of the structure corresponds to the distance between the wheels of the vehicle.

This method has several disadvantages:

It is necessary to allocate a piece of land for arrangement. If later the flyover needs to be removed, its dismantling will require considerable time and effort.
After a while, under the influence of overloads, the brickwork may collapse, as a result of which it may need to be dismantled.

The design is based on several railway sleepers. Sleepers stacked one on top of the other form two bases. The tracks are laid across to ensure the drive. So that the overpass made of sleepers does not disperse during operation, it is carefully fastened with brackets.

This design also has certain disadvantages.

Sleepers are not so common in everyday life, 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 space for railway sleepers is required.

The use of an overpass made of railway sleepers is justified in a summer cottage or garden area, when the structure is left outdoors all year round. To protect it from decay, the product is impregnated with creosote.

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 starting 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 are ease of assembly and 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, ordinary carpentry tools that are in every home are enough. Among the disadvantages of a wooden structure, one can note low durability, weak resistance to decay and insects. Partially these problems can be solved with the help of treatment with antiseptics, fire retardants and insecticides.

Self-production of a wooden or metal overpass 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, the following materials and tools will be required:

Rolled metal products.
Welding machine with a set of electrodes.
A grinder equipped with several cutting discs.
Rebar pieces.
Fasteners: bolts, nuts.
Metal paint for finishing the structure.

Materials and tools for a wooden overpass

For the manufacture of the simplest portable wooden overpass, a minimum of materials and tools will be required:

Boards 45-50 millimeters thick. If thinner boards are used, additional vertical supports are installed in the center of the overpass.
Two wooden blocks.
Two pieces of wagon board.
Screws (150), nails (300), screwdrivers, hammer, wood saw.

Before making the overpass, 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 a car wheel with a small margin. The distance between the settings is equal to the distance between the wheels of the vehicle. At the same stage, tools, materials and place of work are prepared.

All dimensions are approximate and calculated for each car model

If a metal overpass is planned to be used in several places, or it is needed only 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 trestle is as follows:

The finished structure is cleaned with a metal brush, degreased and painted.

The finished design will look something like this

The simplest wooden overpass is assembled from two pairs of wooden beams with a section of 20–20 cm. The beams are knocked down in pairs, cut at an oblique angle. The impromptu flyover is ready.

The improved wooden overpass is assembled from scraps of boards that are knocked together into a wide "pyramid shield". On one of the sides, a stepped slope is formed for a car to enter.

Another version of the mini-flyover is assembled from four 50-mm boards, two blocks, lining and fasteners.

The blocks are sawn to the same length. The upper edge is cut at an angle, at the end you need to leave a small stop.
Arrival boards and bases are attached to the deck. For this, long nails and screws are used.
Safety strips are nailed to the side of the decks.
Blocks are nailed from above, limiting the movement of the car beyond the overpass. Assembled from four planks and beams

A similar design is used for the repair of passenger cars. For heavy vehicles, it is worth installing a stationary overpass.

Every 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.A good help in repairing a car for its owner will be a do-it-yourself flyover in the garage or next to it. But such a design is cumbersome and takes up a lot of space, and visiting a service station for the sake of minor repairs is not always cost-effective. In the absence of large areas for servicing a personal car, an overpass for car repair can be made in another version. Image - Do-it-yourself overpass for auto repair

The task of such a device is to facilitate access to the suspension and the underbody of the vehicle. In this case, only the front or rear pair of wheels is raised to a small height above the ground. Under the other, during inspection and repair, you need to put stops to prevent accidental rolling off an inclined surface.

The simplest way to make a flyover is ladders. They can be made of wood or metal thick enough to support the weight of the machine. You will need:

a board with a thickness of at least 5 cm or a metal corner 4x4 with a thickness of 4-5 mm;
timber (the thickness depends on the height to which it is convenient to raise the car);
grinder and welding machine for working with metal;
saw, nails for working with wood;
roulette.

For manufacturing, you need to calculate the length of a board or a metal bridge for colliding wheels so that in a horizontal position this part does not damage the bottom of the machine. Making wooden ladders is reduced to sawing off 4 pieces of timber for the base and boards for the bridge. The width of the bridge must be sufficient for free wheel travel (at least 30-35 cm). Nail the pieces of timber to the boards in the position shown in the figure: in the middle of the ladder and at the edge of it.

When making a bridge from metal, you need to cut a corner with a length equal to the calculated length of the bridge (4 pcs.). Connect these parts in pairs with short sections of the same angle or reinforcing bar 15-17 mm in diameter. The resulting "ladders" are able to withstand the weight of a passenger car. On the underside of the bridges, weld the base from the corner in the form of a U-shaped structure. The height of the base is selected individually. The base posts should be positioned in the same way as in a wooden structure. When hitting the ladder to the first support of the base, under the weight of the machine, the automobile overpass comes to a horizontal position, and its rear part rests on the second base post.

There is another version of the mini-flyover. These are 2 small home-made welded structures from a 4x4 corner 5 mm thick in the form of a fixed bridge with inclined entrances for lifting one pair of wheels. The length, height and width of each part can be calculated individually, depending on the car brand. When manufacturing, it is required to weld 4 rectangular frames from the corner, connecting them in pairs with crossbars at the bottom. On the upper part, weld pieces of a bar or corner along the width of the bridge.
