How to make an inspection overpass for a car. Do-it-yourself overpass: features of manufacturing different options

Overpass - indispensable tool for inspection and repair passenger car. A small mini-structure 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-overpass. 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 carry out a routine inspection of the car exclusively at a service station and pay out of pocket even for an oil change.

More experienced drivers do most of the work themselves. To do this, a homemade overpass is often installed in the garage - a structure with which you can examine the bottom of the car.

There are two types of overpasses:

To a first approximation, the functions of the overpass are similar to the inspection pit. It provides access to the underside of the car. However, when high level Given the occurrence of groundwater at the site where the garage is being built, it is not advisable to equip an inspection hole: it will constantly be filled with water, which will require additional equipment drainage system, and on metal parts Cars will experience corrosion due to increased moisture.

A full-size overpass is monolithic design, which 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 the driveway. 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.

A mini-overpass is a small portable structure designed for partial collision with a car. It is based on two independent parts that are not connected to each other. The car drives onto the prepared platform with its rear or front wheels, rises slightly above the floor or ground and allows the car owner to carry out an initial inspection or cosmetic repairs.

The advantage of a mini-overpass is the ability to use it in limited space. After work it can be put aside. The main disadvantages of the design are as follows:

To enter the platform, pinpoint precision is required. Otherwise, the structure may overturn or the vehicle may be damaged.
Structural elements are installed in places where there is no possibility that they will diverge in different directions from the slightest push of the wheels.

General requirements

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

The height of the full-size repair structure is about a meter. This allows you to easily 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-overpass with partial access is about half a meter: it does not involve 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 down to the millimeter; when calculating the design, you need to make small allowances. The car must drive onto the platform without hindrance.
Mini-overpasses are used for inspection and repair of passenger cars. For a stationary structure, an additional margin of safety is provided. Thanks to this, the product does not deform over time. You can also roll fairly heavy vehicles onto it.

Material selection

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

Brick construction

Brick overpass - stationary design, which is more often used in rural areas or outside the city. Construction is carried out using the brickwork method on cement mortar. The width of the structure corresponds to the distance between the wheels of the car.

This method has a number of disadvantages:

It is necessary to allocate a plot 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 collapse, which may require dismantling.

Overpass made of sleepers

The structure is based on several railway sleepers. The sleepers laid one on top of the other in a “slide” style form two bases. Tracks are laid across to ensure access. To prevent the sleeper trestle from moving apart during operation, it is carefully secured 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 of railroad ties requires space.

The use of a trestle made of railway sleepers is justified in a country house or garden plot, when the structure is left on outdoors all year round. To protect against rotting, the product is impregnated with creosote.

Made of 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 starting repairs. 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 trestle can last about ten years or more.

There are also some disadvantages. The metal is initially susceptible to corrosion, so before work the material must be treated with special impregnations.

Among the main advantages of a wooden trestle are the 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 found in every home are sufficient. Among the disadvantages wooden structure One can note low durability, poor resistance to rotting and insects. These problems can be partially solved by treating with antiseptics, fire retardants and insecticides.

Tools and materials

Independent production of a wooden or metal overpass requires the availability certain materials and tools. There is no need to purchase complex specialized equipment; it is enough to purchase household power tools, which are sold in every store.

What is needed to build a metal overpass

To make a regular metal overpass you will need following materials and tools:

Rolled metal.
Welding machine with a set of electrodes.
Grinder equipped with several cutting wheels.
Pieces of reinforcement.
Fasteners: bolts, nuts.
Metal paint for finishing the structure.

Materials and tools for a wooden overpass

To make the simplest portable wooden trestle you will need a minimum of materials and tools:

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 carriage plank.
Screws (150), nails (300), screwdrivers, hammer, wood saw.

Preparing for work and drawing up a drawing

Before making the overpass, it is necessary to carry out a number of measuring works. The mini-overpass consists of two independent installations. The width of each of them corresponds to a car wheel with a small margin. The gap between installations is equal to the distance between the wheels of the car. At the same stage, tools, materials and work site are prepared.

All dimensions are approximate and calculated for each car model

DIY metal structure

If a metal overpass is planned to be used in several places, or is needed only occasionally, the structure can be made in a collapsible version. This will allow you to quickly assemble it as needed within half an hour.

The assembly of a metal overpass occurs as follows:

The bases of the cabinets are assembled. The blanks are cut based on the size of the car wheels. The blanks can be laid out into chipboard sheet or other flat surface and fix it at an angle of 90 degrees (you can use a regular construction corner). After all measurements, the workpieces are welded together.
All parts are connected at right angles
The racks are being assembled. The height is about half a meter, the angle is about 120 degrees. Fixed, scalded.
Corners and side walls should be equal
The upper 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.
The finished supports are connected to the base, set at right angles and welded.
After assembly, you can additionally weld the main components
The dead end of the cabinet is welded. This is necessary to prevent the car from driving further and turning over. The part is made from a corner 63*63*5 mm.
Reinforcing bars are welded to the finished cabinet. To adjust the distance between them, you can use the same corner 63*63*5 mm. The reinforcement sections are laid so that their “herringbones” intersect.
A regular construction corner with a side of 63 millimeters is used as a template.
Assembly of gangways (bridges). The blanks are cut and fixed with clamps on the corners. Sections of reinforcement are welded to the corners, the distance can be determined using a template corner, the “herringbones” intersect. The corners are welded to the workpieces.
The car will drive onto the overpass using these bridges
The final stage- fit. On level ground, both parts of the overpass are placed close to each other. The centers of the bollards are marked, the structure is adjusted to the width of the car. Holes are drilled in the ladders and cabinets, after which the elements are connected to each other using bolts. Thanks to the bolted connection, the overpass can be easily disassembled and reassembled later.

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

The finished design will look something like this

Making a wooden mini-overpass

The simplest wooden overpass assembled from two pairs of wooden beams with a cross-section of 20–20 cm. The beams are knocked together in pairs and cut at an oblique angle. The improvised overpass is ready.

An improved wooden overpass is assembled from scraps of boards, which are assembled into a wide “pyramid shield”. On one side there is a stepped slope for cars to drive in.

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

A similar design is used for repairing passenger cars. For heavy transport it is worth installing a stationary overpass.

Video: Assembling a metal structure

Every car owner can make a mini-overpass on his own. It is very important to check the strength of the structure before driving a car onto it and starting renovation work.

Every car owner knows that the main “sores” of a car are hidden in two places: in the engine compartment and under the bottom. You can get to the engine by opening the hood. But you won’t be able to fix the suspension or remove the transmission without getting under the body.

To perform work under the bottom of the car, you can use a pit, a lift or an overpass. The pit can only be installed in dry soil, so it is not available in all garages.

A lift is an expensive pleasure that a repair shop can afford. As a result, the average car enthusiast is left with a homemade overpass for the car, which does not require large costs and time to assemble.

In this article we will look at the most popular and affordable structures, and also describe step by step the process of their design and installation.

Main types of road overpasses

Depending on the budget and complexity of the repair, there are two types of overpass structures:

Allows you to raise only one axle of the car (front or rear).
Full-size (designed to accommodate the entire car).

The first option is economical and convenient. The mini-overpass for partial entry has small dimensions and weight. It is easily installed on a level surface and removed after the repair is completed. The main disadvantage is that it is not as convenient to use as a full-size design, since the lift of the car here does not exceed 50-60 centimeters.

The full-format option is more expensive and more difficult to implement, but gives the car owner simultaneous access to all body components. Let us note in passing that, regardless of the type of overpass, for its high quality workmanship you need to make a drawing, and when assembling it, you need to accurately maintain the dimensions of the structure.

Three groups of sizes are especially important:

height and width of the supporting pedestals of the “chairs”;
length of the ladder (entrance and horizontal);
ladder width.

In addition, attention should be paid to the junction points of the ladders with the pedestals. They must support the weight of the car without deformation.

Popular options for overpasses for car repairs

The simplest type of mini-overpass is two pairs of scraps knocked together wooden beam with a cross-section of 20x20 cm. By cutting the edge of such an improvised support at an oblique angle, we will get a solid platform onto which you can drive the front end or back the car (photo No. 1).

Photo 1. Two pieces of timber - the simplest lifting device for repairs

The disadvantages of such a support are obvious: there are no sides on the beam to protect against lateral sliding of the wheels, which requires the driver to be extremely careful when entering. There is also no rear bumper to prevent an accidental slide. The height of the stand is not sufficient for easy access to the bottom.

There is a better option wooden support for performing simple repair work. Such a flyover at the dacha is made from scraps of boards, sequentially knocked down into a wide board. One side of it forms a stepped slope for entry (photo No. 2).

Photo No. 2 Mini-overpass made from scrap boards

This design has a bumper bar and two carrying straps. Its width can be chosen so that you can drive in to inspect the car without the risk of the wheels falling off. The cost and complexity of manufacturing such a stand are minimal.

Most often, mini-overpasses are made of profile metal (pipes, angles and fittings). They are more durable and stronger than wood. You can see an example of such a design in photo No. 3.

Photo No. 3 Stand-overpass from a corner

Instead of a corner for the supporting part of the ladder, you can use fittings or a pipe. By extending the horizontal ladder by 1 meter, we will get a mini-overpass that is more convenient for work. Using it, you can get to most of the units located under the bottom of the body (photo No. 4).

The review of compact designs is completed by a mini-overpass for a collapsible car. It occupies an intermediate position between portable and stationary options (photo No. 5, 6, 7).

Photo No. 5 Portable overpass assembled

An important feature of this design is the ability to dismantle the horizontal ramps after the vehicle enters for convenient access to the wheel arches and sills.

Photo No. 6 Option for partial assembly of an overpass for lifting one part of the body

Photo No. 7 When disassembled, the universal overpass fits completely into the garage

It is possible to work while lying or sitting under a car, but it is not very convenient. Therefore, for regular repairs, you need a stationary high overpass, assembled at columnar foundation(photo No. 8).

Photo No. 8 Stationary metal overpass on a concrete base

This design, if necessary, will accept not only a passenger car, but also a small truck or bus.

How to make a collapsible car overpass yourself?

The manufacturing of the structure begins with the preparation of a detailed drawing. When doing it, you will be able to take into account and think through all the stages of assembly, avoiding the mistakes inherent in hastily completed work.

The collapsible overpass must have the following dimensions:

Length of entrance and horizontal ladder equal to the length of the car + 1 meter.
The width of the ladder is at least 40 cm.
The height of the supporting pedestals is 70-80 cm.
The width of the upper part of the support pedestals is equal to the width of the ladders.

In order to make the overpass durable, you should not skimp on metal. For drains you need to buy a 63 mm equal angle angle. Supporting pedestals “chairs” can be welded from a corner with a shelf width of 50 mm. The filling of the drains is done with corrugated reinforcement with a cross-section of at least 14 mm.

Without welding machine, grinders and drills, it’s better not to start working. In addition to the assembly tool, you need to prepare 12 pairs of bolts and nuts for attaching the ladders to the “chairs”.

Stages of work

The first step is making the support pedestals. They need to be given trapezoidal shape to improve sustainability. To accurately assemble the base and upper part of the “chair,” the corners cut to size must be laid out on an OSB board, secured together using clamps or welder magnets.

First, the lower bases of all four supports are welded. Then the frames of the upper platforms are assembled and the legs from the corner are attached to them. The final stage is the installation of the upper frames with legs into the lower supports and fixing them by welding.

Please note that in the assembly diagram one of the corners of the upper frame is turned upside down and forms a bumper to protect the wheels from falling off the overpass. One more fender corner needs to be welded on the end supports. They will not allow the car to move off the ramp.

In order to make the overpass with your own hands as stable as possible, you can install transverse links on it from steel profile. It is bolted to the pedestals. This measure will not be superfluous, since it will increase the rigidity of the entire structure.

The horizontal and entrance ramps are made from a 63 mm angle and reinforcing bars that act as a “ladder”. Length of inclined ladder for passenger car must be at least 3 meters. Size horizontal section chosen by adding 1 meter to the length of the car. The width of the ladders is at least 40 cm.

Before installing the reinforcing bars, the corners are turned over so that their flanges face up and serve as outer side edges. The “ladder” will be level if the profile is laid on a solid horizontal platform. It is difficult to attach it to concrete or asphalt. Therefore, you can use two transverse angles as a mounting base. The guide “ladders” are attached to them with clamps. Having completed this operation, you can begin the welding process. It will be more convenient to align sections of profiled reinforcement using a 63 mm corner piece as a template.

Making an inclined ramp for an overpass for car repairs is slightly different from assembling a horizontal one. You need to leave a free end 10 cm long on it (without reinforcing bars), which will serve as a connecting point. The vertical edge of the profile is cut with a grinder to the horizontal shelf. After this, it is necessary to bend the connecting ends.

If you don’t have a bending machine, but have a couple of friends of considerable weight, then ask them to climb onto the pedestal to counterbalance the bending force. Before this operation, you need to lay the entrance ramp horizontally, supporting its free end. Two holes are drilled locally in the supporting part of the profile and the corner of the “chair”. Having fixed the ends of the “ladder” with bolted connections, it is tilted with force down to the ground. In the place where the profile was cut, you need to weld a piece of steel plate to strengthen the support unit.

The horizontal ladder is mounted by laying it on pedestals. After this, holes are drilled for the bolts in the supporting corners and the upper support profile of the cabinet. For more reliable fastening of the overpass to the site, eyes can be welded to the “chairs”. By fixing them with dowels to the concrete or steel pins to the ground, you will protect yourself from the displacement of parts of the overpass when a car enters it.

When making a test drive, pay attention to the behavior of the inclined “ladder”. If it bends, you will have to make two intermediate support frames and bolt them to the corners.

Design features of many cars and their specifications involve regular preventive inspection and repair of various components and systems. What can you do, it's just a machine and like any equipment, it requires care and attention. However, if in some cases it is possible to carry out repair work from above by lifting the hood, then any inspection of the suspension and chassis becomes a real pain if there is no inspection hole or overpass. It’s quite expensive to constantly take your four-wheeled friend to a car service center, and it’s not necessary, because many of the jobs can be done with your own hands. Therefore, installing an overpass for cars is a top priority for any car owner who cares about the smooth operation of his car.

Requirements for the overpass

In order to ensure safety and ease of operation, it is better to make the overpass taking into account the following requirements:

The height of the overpass for car repairs must be at least 1 meter. Otherwise, it will be very difficult for you to get under it, there will not be enough light to inspect the chassis, and there will be no free space for manipulating parts and keys.
The width depends on the type of vehicle (truck, passenger car), but should not be minimal, centimeter per centimeter. It is necessary to make allowances in the calculations so that the car can drive onto such a platform without problems.
For greater reliability, it is necessary to provide a safety margin when constructing an overpass. This will help not only to avoid deformation of the structure, but also, if necessary, to roll heavier vehicles onto it.

Types of inspection platforms for cars

In principle, there are only two options for arranging an overpass on your site. Each of them has its own pros and cons and manufacturing features.

Mini overpass, is a portable structure for partial collision. Consists of two separate parts that are not welded together. The car can drive onto such a platform with its front or rear wheels, allowing the owner to carry out repair work.

Plus - this overpass can be used even in conditions of severe shortages free space and after repairs, put it aside. The downside is that driving onto the structure requires pinpoint precision and the elements need to be installed only in places where they will not move in different directions from the push of the wheels.

Full size overpass much more convenient and reliable, but its construction will require free space. But it will last for decades, saving its owner a lot of money, because many repairs can be done at home. The advantage of this design is reliability, strength and durability. The downside is the need to allocate free space and some high costs for materials.

DIY mini overpass for a car

In order to make a mini overpass with your own hands you will need:

Steel corner with a thickness of at least 10 mm;
Metal rod;
Electrodes for welding;
Welding machine;
Finished protection paint metal structure from corrosion.

The load-bearing elements, the “heels” on which the access ladder will be attached, should have a width of about 40-45 cm. The supports are welded in the form of a trapezoid, where the bottom, the base, is 10-15 cm wider than the top. This is necessary to give stability to the structure. The access ladder is made of two pieces of angle with a transversely welded rod, which allows the wheels not to slip when climbing onto the structure.

To fix the car in the desired position, it is necessary to make special gaskets, which are used to prevent the car from spontaneously sliding off the overpass. After completion of the work, the entire structure is painted.

Full-size car repair overpass

Even at the stage of choosing a site for construction, it is necessary to determine the size of the overpass for passenger cars. Since the width of the car and the required length of the platform are not constant values, there is not and cannot be a single size. Today you may have a small subcompact car, tomorrow a huge jeep or a small truck. Therefore, the overpass must be made with a good margin of safety and allowances.

At the first stage of construction, the overpass is dug in steel pipes(6 pieces) with a diameter of at least 80-100 mm to a depth below soil freezing. If you go deeper, there is too great a risk that the structure will move to the side during the first spring thaw. The hole under the post is not filled with soil, but filled with cement.

The inclined part (drive) is made of a metal angle with a steel rod welded transversely. The distance between the rods is about 10 cm.

The horizontal plane is performed in the same way, only at the end of the overpass it is necessary to make a limiter that will protect the car from uncontrolled sliding forward.

As a rule, the length of the inclined part is up to 4 meters, and the horizontal plane is up to 3 meters. This is quite enough to repair a passenger car of any make and design.

As you can see, the question of how to make an overpass for a car with your own hands is solved quite simply.

To do this, you need basic skills in working with a welding machine and some free time. But the result will exceed all expectations and you can not only repair your car to your heart’s content, but also wash it from all sides.

We want to be able to understand and repair everything, so as not to attract outsiders and not pay for it with funds that are now not so easy to obtain. Some delve into the design of various mechanisms simply for the sake of hobby. For both, information on how to build an overpass in a garage with your own hands will be relevant.

When it is not possible to make a viewing hole

Inspection pits have become very popular and widespread. They are relevant for garages with low ceilings, where it is not possible to raise the car. In some areas groundwater are close enough to the surface, and thorough waterproofing must be done so that the inspection of the vehicle does not turn into acceptance cold bath. If this is also true for you, or you simply don’t want to bother with wasting effort on excavating soil, then an overpass will be the ideal solution.

There are two main types of overpasses:

stationary;
collapsible or mini-overpass.

Overpass construction

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

Note! At correct production overpasses and calculations, you can raise your car almost a meter above the ground.

You will need pipes with a total length of up to 2 m. At approximately 1 m they will have to be buried in the ground and securely concreted. You will need from 4 to 6 such posts, it all depends on the size of the machine. Four corners measuring 7.5 by 7.5 cm are fixed on top, the space between them is filled with reinforcement rods, which are welded perpendicularly. In the same way, the driveway is installed at an angle. It is imperative to provide limiters in the design that will prevent the car from rolling back or driving further forward. The length is selected to suit specific needs.

Other types of overpasses

But not all of us have two cars or large garages in which to play football or hold a party, so it’s worth paying attention to mini-overpasses that can be dismantled or freely moved around the territory and stored in a garage or shed. Making them will require some ingenuity. Here are a few options for you to choose from:

rectangular trapezoid;
"rocking chair";
reversible;
based on sleepers.
One-sided pyramid. To make this type of platform you will need a minimum of effort, time and money. You need to have approximately 17 m of boards on hand, 5 cm high and 30 cm wide, maybe less if you are an ace at driving on a narrow gauge railway, but it’s better not to risk it. Next, we cut out two beams of the same length with the following dimensions: 45 cm, 70 cm, 95 cm, 120 cm, 145 cm, 170 cm and 195 cm. After all the parts are ready, you can start assembling - just connect them together so that at one end they create a plane, and at the other they look like a ladder. You can use nails or self-tapping screws - whatever is at hand or more convenient for you. The assembly process should have resulted in two pyramids, cut off on one side. But such an overpass is not yet suitable for a car to drive onto it. The two blocks may suddenly separate and cause damage to the underbody, or the vehicle may overturn. To prevent this from happening, we do the following. On internal sides We mount two two metal corners with holes. Next, choose two metal or wooden slats. We make holes along the edges and attach them to the corners. After such an operation, the stands will not move to the side. When the car is already on top, carefully unscrew the safety crossbars and carry out the necessary repairs.

A similar trimmed pyramid or trapezoid can be made from metal channel, it will turn out to be much more reliable and durable. Instead of climbing with a “staircase”, you will simply need to make an inclined drive.

Note! Using such a device, the car can be raised by 30 cm; if a greater height is needed, add a few more bars of greater length. Be sure to install restraints at the front to prevent the vehicle from rolling forward, and secure the rear wheels.

The “rocking chair” is also a very simple design that any car owner can make. We select two boards as thick as in the previous example, the length can be 1 m. We take four 10x10x30 cm blocks 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 secure it firmly and do not forget to place emphasis. Now, when the car runs over its wheels, the boards will be thrown over due to a shift in the center of gravity; with further advancement, they will be supported by two bars. All! The car is up! Repairs can be made. You can vary the dimensions, focusing on the ground clearance of a particular vehicle and the length of the wheelbase.

There is another version of this overpass, it is a little more complicated to implement, but much more reliable. Designs may vary. Here is one of them. Take a 30×30 corner, larger if possible, adjust the length based on your car. We will need 8 such segments. We connect them in parallel using reinforcement bars. The result should be 4 bases same size. The lower parts can be made longer and wider for greater stability. Next 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. We install 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 movably connect it to the lower base. If you do not touch the stands, they will be folded at an angle. When the car moves along them, the wheel shifts its center, aligning the horizontal, and rests against the block. Now you can use the latches to secure the platform in this position.

Using a platform is an interesting approach to the matter. To make it, you need to get a corner we already love, or use a square profile. Next, using a welding machine, 2 isosceles triangles are made so that the base is 1.5 times longer than the wheelbase, and the apex angle is obtuse. The platform is placed on them. Now everything is ready. The car drives onto the structure and, resting against the limiters, reaches the end.

Note! Place stands under the rear wheels to prevent the car from rolling away when it is on an overpass.

The sleeper-based trestle is very easy to make. Two sleepers are laid, one in continuation of the other. Strong boards are laid on the part with the recess, after which a small slide is created. That’s it – the platform is ready, you can move in and make repairs. The disadvantage is that the sleepers need to be stored somewhere, although it is unlikely that anyone will decide to take them away from you. For this kind of platform it is not necessary to use sleepers; anything that can securely support the boards will do.

Note! Constructing homemade overpass, do not forget to protect your car by installing limiters - they will prevent the car from falling off the overpass.

As you can see, there is no particular difficulty in lifting the machine for servicing. 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.

Mini overpass in the garage

During the current and major repairs The motorist has to pay a lot of attention to the engine compartment and... Some operations with the engine can be performed from above, but when diagnosing or restoring the suspension, you will have to work on the car from below. There are two ways to ensure comfortable mechanic conditions in such situations: lower the repairman into the pit or lift the car onto an overpass. Most people prefer lifting the car because it is a less expensive option. However, before making an overpass, it is necessary to prepare a project and select materials and tools for it.

Methods for making a car overpass with your own hands.

Popular types of automobile overpasses

Craftsmen realized a large number of various designs that help to conveniently position the machine before repair. Thanks to such successful results, popular groups of auxiliary equipment can be distinguished:

For one bridge. In such a situation, the car will have only one axle, front or rear. The advantage of the form is its compactness, since it is not required large area for her. The disadvantages are that the method is not suitable for complex repairs.
Full size type. The format allows you to pile up the car by completely raising the entire body to a sufficient height. The option is relevant for working under the entire bottom, but requires significant space and a larger volume of materials for implementation.
Stationary type. Mounted in one place, for example, in a country house, which minimizes mobility. At the same time, it may have good equipment, a close distance to electrical and pneumatic connections, and an indoor type is allowed.
Mobile variety. Presented in the form of cabinets made of metal or wood. For installation you need a flat area. After completion of the work, the construction is easy or different utility room. Easily adapts to any type of vehicle, subject to load limits.

Important! A mobile overpass for cars, made by yourself, can be intended for either one bridge or two.

How to make a collapsible car overpass yourself

Most motorists prefer collapsible overpasses. This is due to the fact that they can be made independently with minimal costs, which will allow them to quickly pay for themselves. At the stages of development of this auxiliary device for repairing a passenger car, you will need to take into account some, which include:

the width and height of the base pedestals on which the structure rests;
length of the driveway and horizontal platform;
width for inter-wheel space (track).

Basic knowledge in the field of strength of materials is welcome, which will help form strong components and joints of the product that can withstand the weight of the vehicle without rupture or deformation. You should not skimp on materials.

After various repairs There may be scraps of boards left. It is rational to use them to make a trestle with your own hands, since a wooden product will have minimum weight with optimal strength. A popular design is a pair of meter-long bars with an approximate cross-section of 200x200 mm. On one side wooden blanks cut at an angle of 40-450 to form the drive-in part. Next, we nail the parts onto a two-meter board with a cross-section of approximately 200x40 mm. We place the finished products under the wheels and can drive onto the mobile mini overpass made of boards using one of the bridges. For optimization, we recommend placing a front block on top as a sliding stop. Although the lifting height is small, it will allow a number of operations to be carried out under the machine.

Another wooden variety The structure is made from scraps of boards with blanks of equal thickness. Typically, the base for each support is a pair of strong, wide slats, about 40 mm thick. and 1.5-2.0 m long. They are filled with steps across the planks to the required height (about half a meter). The front part is also equipped with anti-rollback. For ease of carrying, loops-straps made of durable material. The total cost of the product is minimal.

A do-it-yourself metal overpass on a level surface is more reliable. The product will be much heavier than its wooden counterpart, and also more expensive to manufacture. However, the homemade product will last much longer and will be able to withstand heavy vehicles. To make a metal slide you will need any material:

profile rolled products (hollow square or rectangle);
pipes or fittings;
corner.

Everything is joined together using a welding machine. Ready product We recommend painting. Vertical racks we recommend making from profile pipe. It is preferable to make the horizontal platform from reinforcement, and the entrance - in the form of steps from the corner. It is advisable not to increase the approach angle, so 30-350 will be the optimal value. The horizontal part at the top is completed with a vertical stop that prevents rollback. The height of the racks is selected at the request of the car owner. The design can be used both for full vehicle entry and as a mini-overpass for entry via one bridge.

Convenience for users is provided by the collapsible type of overpasses. The option belongs to an intermediate type between stationary and mobile structures. Due to its large dimensions, when assembled, the slide provides a lot of space for repairmen, and when disassembled it takes up little space. The constructor consists of elements:

four base cabinets;
two horizontal slabs for moving;
two inclined slabs for entry.

The pedestals are arranged in a special way so that each of them is under the wheel of a car. A maneuver in which the horizontal beams are removed, while the car remains standing on the pedestals, helps improve accessibility to the wheel arches. For a stationary version of the overpass, you will need to find a flat, free area. Cabinets are usually made of brick, cinder block or poured concrete. We weld entry and horizontal beams from metal corners, fittings and rolled products. The reinforced platform can accept proper planning not only cars, but also trucks.

Step-by-step production

At home, after preparing a plan, you can begin production by assembling the cabinets. They can be made with right angles and dimensions of 60x60 cm and a height of up to 80 cm, or the top can be reduced to a cone with a platform of 50x60 cm. Assembly can be carried out from wooden OSB boards or cook from a corner. For an inclined ladder we use two three-meter corners 60x60 mm, located parallel at a distance of 40 cm. We lay a ladder between them at intervals of 60-65 mm. fittings with a diameter of 14 mm. and weld it. The horizontal ladder is made in the same way.

Conclusion

Each motorist chooses which type of overpass to assemble based on current needs and prospects. The optimal option is a mini version or a prefabricated structure. Craftsmen choose between cheap, practical wooden products and metal expensive but durable structures.
