Landscaping homestead can be considered complete if a "complete set" will be independently built overpass for car repair. Dizzying designs of trestle striking laconicism and the ability to use the simplest metal. Do you dream of making a flyover with your own hands? What can be more exciting!

Personal car service
Almost every homeowner dreams of seeing his own homestead attractive, practical and functional. And if the landlord is also a passionate motorist, then there is simply no way to do without an overpass designed to repair cars on the site.
Even if you do not plan to service the car on your own, periodic inspection will help in time to identify problems and turn to a professional workshop. To access the car use special lifts observation pit and flyover. However, expensive special equipment and a well-equipped observation pit are strictly the prerogative of service centers, which requires considerable material costs.
The overpass for the car, on the other hand, can be installed anywhere on the site, almost next to the potato beds, and note, with your own hands. It is possible to build a flyover for cars for cars and trucks. The area of use and application of such a trestle can be expanded and the services of a "personal car service" can be used at any time of the day or year.
Construction of overpasses
Constructively distinguish the following types of trestles:
• for partial arrivals of cars
• full-size trestle.
Naturally, depending on the size of the trestle structure and the bearing capacity to withstand the load, these types of trestles are used for a certain weight of cars. The only condition is to limit the size of the overpass for your existing car or two.
The classic design of the trestle (almost from the words of the driving instructor) has a certain height, width and length of the working part, limited by the bevel, and also along the sides of the walkway.
trestle for partial auto arrival
Trestle for partial arrival of cars (portable and mini) is a lightweight portable structure consisting of separate parts welded together. Portable and mini trestles are installed without a foundation. Check in this trestle for the subsequent vehicle inspection is possible with front or rear wheels.
This trestle for cars is simply installed and also easily retracted, allowing you to save space on the site. However, for a successful arrival on the construction, you will need the dexterity and dexterity of the driver.
The main parameters of the flyover:
• height - not less than 1 m.
• width - 2.5 m.
• length of bevel - 4.2 m.
Constructively portable or mini overpass consists of four parts.
The flyover is easily assembled and disassembled, and also transported to the desired location, so for a sudden diagnosis of a moody car, such an overpass is indispensable, especially in the "field conditions". In practice, sometimes it is necessary to make two overpasses to raise the front or rear of the car to the required height (clearance plus trestle height).
This is how the trestle, made independently, used for partial arrival looks.
full-size flyover
Of course, a full-sized overpass is a more convenient and reliable construction, for the construction of which you need a workspace. But the full-sized overpass in the future with more than pay back the cost of its construction.
The main parameters of the full-scale trestle are similar to the parameters of portable and mini overpasses:
• height - 1 m and more
• Width up to 2.5 m.
• length of working part - 4-6 m.
• the length of the bevels on both sides is 4.2 m.
Let's talk at once, that the sizes of a full-size trestle for cars are not a constant value.
Therefore, a full-length overpass is manufactured 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 a viewing platform for a car, equipping a pit of observation.
How to make a trestle for a car with your own hands
Theoretically, it is possible to make a flyover for a car from any improvised material. In the course are boards, bricks and used tires. But such temporary measures can be justified only in extreme cases.
Therefore, for the main load-bearing elements and tracks of overpasses, metal rolling is used, capable of withstanding significant daily loads. This is a metal channel, corners and a profile pipe. These types of rolled metal can withstand significant bending stresses.
how to make a mini overpass
For the manufacture of a mini flyover the following materials are required:
• corner steel, thickness not less than 10 mm
• metal rod.
as well as welding electrodes and a welding machine. The form of the support of the mini overpass is "trapezium", with a base 15-20 cm larger than the upper part. A ladle for the arrival is made from steel corners, on which the bars of the rod are welded evenly on both sides.
The surface of the rod is preferable to choose grooved so that the wheels of the car do not slip when lifting and descending the overpass.
Bearing elements of the flyover, on which the ladder is attached, should have a width of 45-50 cm. Fixing cars are carried out special gaskets, which exclude the spontaneous departure of the car. After welding, the trestle construction is painted with anti-corrosion paint.
A mini overpass for car repair is presented in this video.
how to make a full-size flyover
Initially selected on the site is a site on which there are no intumescent soils, groundwater and ground do not have a water-saturated layer. Prepare the pits under the trestle base - poles or steel pipes, up to 10 cm in diameter.
The number of pipes of the base of the full-scale trestle is calculated according to the preliminary working sketch. Pits with installed pipes are cemented. To the installed pipes or poles, a channel is welded to strengthen the bearing capacity.
It is also recommended to use metal rolling (channels, angles and profile pipe) as carrier elements for tracks. Then the rolling plane is made: the reinforcement and the cut rods are welded across the bearing elements on both sides.
The width of the track of the rolling plane must be at least 0.5 m. The received welded structure is placed on special supports of the required height (1 meter). To make a landing for the arrival and stairs use the corner L 50, welded with the armature. The edges of the tracks are preferable to protect the corner, preventing the car from slipping.
