For body repairs simple tools is often insufficient and requires specialized and expensive equipment. Deformation of the main parts does not always mean the need to replace them. Restoration of body geometry can be performed in the workshop, but these services have a considerable cost. If you have the appropriate equipment, you can easily carry out repairs yourself. To perform such work, you will need a home-made slipway, the assembly of which will not take much time.
A slipway is a mechanical equipment whose task is to restore the original state of the car frame and body geometry. Straightening of deformation bends, dents and other irregularities is carried out using local loads. In most major body geometry modifications, the slipway is the only possible solution to restore the shape of the car frame. The presence of such equipment is mandatory for every workshop and guarantees high-quality body repairs.
To decide to make a slipway with your own hands, you need to understand not only the purpose of such a mechanism. Manufacturers offer different functionality of this equipment. Some models are suitable only for work in large service centers. There are also more mobile options that can be installed in a garage or similar room. When buying such devices for personal use, their price will be high and independent production most appropriate.
Deformation of the body can occur for various reasons. Accidentally hitting an obstacle, overturning while driving on rough terrain or getting into an accident do not pass without a trace for the car. Changing the geometry on the spars or a curved car frame can lead to the following consequences:
Such features of damage to the frame cast doubt on the possibility of operating the vehicle. The basic dimensions of the body are indicated in technical documentation every car. Moreover, changing them will require restoring the original parameters in order to continue driving safely. The slipway mechanisms make it possible to almost completely eliminate the deformation and independent creation such an assistant will be a good alternative to contacting a service center.
The use of multidirectional efforts is the most important feature power stand. Such work is difficult to do manually. You can make a slipway with your own hands of various designs. Such devices are made of durable metal, and their features depend on the type of repair being performed. When choosing suitable model the slipway should take into account the parameters of the transport for which it is manufactured. The dimensions of the stand, the characteristics of devices and mechanisms can be selected based on the most successful models of Trommelberg, Nordberg BAS or Autorobot.
Depending on the nature of the work being carried out and the versatility of use, there are several varieties of such power stands. With the help of small structures it will be convenient to carry out local repairs. and a large-sized industrial slipway, equipped with powerful hydraulic equipment, will cope with heavy freight transport. To select the appropriate design, you should know the types and purpose of all such devices.
There is no strict standardization of power stands. Most manufacturers supplement the slipway with various equipment. So, anchor clamps, special grips and a multi-tower design of the stand ensure that the force is generated in the right direction. For use in the garage, you can choose only the most necessary equipment, and the rest can be purchased or made later. All stocks can be divided into 3 types with their own characteristics and functionality.
Frame slipway - is a structure for pulling relatively small deformations. Such a stand is suitable for local work and allows you to high precision restore the geometry of the deformed area. The metal frame has complex structure, which serves to ensure sufficient rigidity. Strong fixation allows you to stretch the vehicle in any direction and change the direction of the applied efforts.
The frame stand is quite popular due to its small size and practicality. Fixing the machine on such a frame is carried out with special grips. A chain connection is used to pull out deformed nodes, which provides recovery right position damaged part. The kit of such an installation should include a lift to ensure the fixation of the vehicle at the required height. The arrangement of such a stand will require various parts to ensure the capture and installation of the machine.
Floor slipway - in use professional companies specialized in body repair. Its design implies fairly high traction forces, suitable even for the restoration of freight transport. In the absence of volumes of work, this system does not take up much space, which provides additional convenience in operation. It is quite difficult to make such a do-it-yourself slipway for body repair due to the huge number of parts. In most cases, the functionality of such a power stand is not needed in a conventional garage.
Any floor slipway needs a specially prepared base. The installation of rail tracks, rack systems, anchors and fasteners requires accurate calculations and the availability of appropriate equipment. The most convenient floor slipway when installing mounting systems flush with the floor, which will ensure the safety of movement and work. The capabilities of such a power stand will be enough to access any area of deformation, and the installation and fixing of the machine does not take much time.
Platform slipway - has some similarities with the overpass design. With the help of such a device, it is easy to pull the car body in any direction. The platform of such a device has huge opportunities for installation. additional equipment. It is most convenient to perform pulling on such a stand, and its functionality is sufficient for professional use or repairs in the garage.
For self-manufacturing, such a design does not present difficulties. Any platform slipway is superior in its capabilities to a frame one and is suitable for most types of vehicles. One or more towers can be used to repair the machine on this stand, which will be enough for the most difficult jobs. The pulling force of hydraulic equipment is unlimited. Moreover, such a platform can be used for body repair of SUVs and heavier equipment.
The stocks are produced by large world-famous companies and small regional enterprises. The price of such power stands varies greatly, but the independent production of such equipment will cost many times cheaper. Depending on the design chosen, drawings should be drawn up, providing for all the features of the future workshop. Then it remains only to prepare the necessary Consumables and tool.
To assemble a homemade slipway, you will need a metal profile, which will form the skeleton of the structure. The assembly process is carried out by welding, and the appropriate equipment must be available. The fastening system is developed individually and it is important to purchase the power rack mechanism, chains and gripping devices that are difficult to manufacture. Before starting work, metal should be prepared by cleaning it from rust, degreasing and priming. After that, you can start assembling the structure.
To obtain a reliable frame, the profile must withstand not only the weight of the car, but also the force created by the tower rack. To perform such tasks, the thickness of the metal of the slipway should not be less than 4 mm. The platform construction of the leveling stand is most convenient for installation in the garage, and special attention should be paid to its design.
The exact dimensions of the slipway depend on the type of vehicle in need of service. In length for such a design, 4.5 m of the profile will be enough, and a width of 2 m will provide convenient installation cars. For the manufacture of the frame, a channel with a cross section of 50-120 mm is suitable, which forms a solid platform for installing the machine. Given that the load from the power tower on the profile will try to deploy it, it is required to install powerful stiffening ribs. The assembly of the frame is carried out using welding tacks, and after fitting, the final welding is performed. In general, all actions have the following order:
When doing such work Special attention structural rigidity is required. It is possible to organize repairs on the slipway only if the machine is securely fixed. Security issues should be carefully considered. The loads acting on the frame of the vehicle during the extraction can not only damage the car, but also cause a significant blow to health.
You can make a slipway of any design, frame or platform are most suitable for such purposes. The main thing is to take a responsible approach to work and show your own ingenuity. Understanding how to make a slipway is quite simple, but right choice material will help reduce the cost of its creation. To implement your own ideas, you should take all the best from existing models. The operation of the slipway is designed for many years and such equipment will prove its practical benefits more than once.
If you have any questions - leave them in the comments below the article. We or our visitors will be happy to answer them.
Whatever golden hands you have, but in order to straighten the body of one hand, it will not be enough, special devices are needed here. In order to restore the body well after an accident, one cannot do without a slipway.
Its function is to firmly fix the car in the process of compressing or stretching the body. The slipways are different in their design, but they can be combined into three types: frame (in the form of an iron frame), platform (for more difficult work) and floor (these are already multifunctional, mobile, professional).
Who really needs a slipway, but there is no way to buy it, I suggest making a slipway for body repair with your own hands, and I will help you with this.
Before starting to make a slipway, I probed the soil well, re-read many articles and reviewed more than one video, drawings on the Internet.
We will make a straightening frame according to the principle of the car. The frame under the car is in the shape of a rectangle, fasteners are attached to the boxes on all four sides, they will come out on the back of the lifting platform, thanks to which it will be mobile.
First of all, measure the length from the front wheel to the rear. The width of the frame must pass between the wheels. Using a welding machine, we weld two metal three-meter sticks and two sticks of 800 mm each. To avoid distortions, we lay everything out on a flat surface.
Carefully so that there are no bumps at the junction, we weld the frame in the shape of a rectangle.
When we finish drilling the blanks, we will deal with scarring and cutting grooves as in the drawing.
On our forum, and on the forums of our auto repair friends, questions constantly pop up on the manufacture of a slipway for body repairs in your garage. Many try to make it with their own hands, but sometimes new knowledge, solutions are required. possible errors and you have to seek help from your colleagues.
Usually, two versions of home-made stocks are considered: mobile and stationary (concrete floor).
In this article, I tried to compile useful information, from our forum including: tips, drawings, photos for making a slipway and give impetus to those who are not yet fully confident in their abilities and are afraid to start making it on their own.
Here is such a slipway made by our forum member Yevsey.
Was taken as a basis lung design and mobile Finnish slipway Autorobot micro A.
The main materials used in the manufacture of steel channel No. 10 and No. 12.
Below in the photo are the main nodes of the slipway.

power towerAn important detail of the slipway is the grips of the rapids, a kind of vise. For their manufacture, sheet steel with a thickness of 16 mm was used. Threshold grip width 150 mm, tightening bolts 12, and bushings 14 mm. The springs were used from the classic Vase valves. "Sponges" of captures are made of a rasp on metal.
To work with this slipway, hydraulics from a set designed for 10 tons are used.
Here is such a chain lock located on the draft tower (boom) of the slipway, as well as how the threshold grips work.
Staple at work:
But actually the scheme itself with the dimensions of the slipway.
To simplify the work, special coasters were welded with the arrival of a car on them in front or behind, and it became easier and much faster to bring the slipway under the belly of the car.
This design of the slipway has the ability to put a fixture to pull down. To do this, you need to upgrade it a bit by placing a sliding roller under the chain links.
Cons and pros of this do-it-yourself slipway design. It may be worth considering them if you repeat this or a similar design.
Cons and improvements:
Pros:
In general, beauty, the car stands dead on the slipway, the hydraulics pull exceptionally easily, as if you are not pulling iron, but cardboard or paper. Before that, I used an ordinary winch, so I can compare and say that this is heaven and earth. The slipway has established itself as a real hard worker, its rating is 5 plus, it is very mobile and reliable.
As one of the options for a small homemade slipway for use in the garage, below in the video from Boris AvtoDok, where he talks in detail about his design.
In the second video, the errors identified already during the work, how he corrected them and what alterations he made.
And now, we have smoothly moved to a stationary slipway, or, as it is also called, a floor one.
Here is a statement by Yevsey, the author of a do-it-yourself mobile slipway and which we talked about in the first part of our article:
If I had originally built this garage for body repair, then I would have viewing hole along its entire length, I concreted the channels, and to these channels I made the anchor fastening of the grippers to the thresholds of the car. And the traction boom would also be attached to anchor fasteners.
I would also put channels or rails into the walls, that is, I would weld a kind of cage so that it would be possible to pull in any direction simultaneously in several directions. Then I think it would be possible to undertake repairs of any complexity.
What is the most important thing in a slipway? The most important thing is that you can securely fix the car and even then it can be pulled in any direction, of course, if the slipway design allows.
I can’t offer drawings for such a slipway, because. I don’t have my own, but for every master, if the slipway is not purchased, but made with his own hands, then he made it according to the principle of his vision of the situation (tasks to be solved, source materials, the size of the garage, finances and other "Wishlist").
Basically, these are channels welded and embedded in concrete with a cut for fastening various fixtures (threshold grips, “tower”).
Some car repairmen make a whole cube from channels throughout the entire volume of the garage. Such a kind of slipway allows you to pull the body in any direction and at any angle. Of course, this solution is the most convenient, but very expensive.
Part one is the overall design and budget.
Part two - Benefits.
Part three - Drawings and full alignment.
If you are going to make a floor slipway with your own hands, then approach this issue thoughtfully and purposefully. Throw a sketch depending on the size of your garage and the proposed work, decide on the list necessary materials think about how and where you can save.
It will not be superfluous to familiarize yourself with various designs homemade slipways, which can be found on the Internet abound. And take the best from them, taking into account the mistakes and shortcomings - learn from the mistakes of others!
The principle of operation for all devices is the same. To restore the geometry of the body, it is fixed on any one or more sections of the slipway. Then the mechanic, by means of an exhaust device and applying force with the help of hydraulic devices, pulls out the deformed elements. If a do-it-yourself slipway is made in the garage, then this is, as a rule, a simple system with one exhaust mechanism. There are several of them in the factory equipment.
There are four types of structures in total, each of which is used in certain conditions. Some types of equipment can be made independently. How are the slipways used today characterized?
Differ in a possibility of use for restoration of a body of the most various cars. The devices available on the slipway allow you to fix the car without flanging the thresholds. Rolling equipment is compact, so it can be used in confined space- that is, it makes sense to make a do-it-yourself slipway for body repair in order to install it in the garage. Minus this equipment in that it cannot be used in the presence of distortions and changes in the geometry of the body.
It assumes the presence of a rail along which retractable devices move. This design helps to carry out repairs of varying complexity, as the mechanisms move to any point on the slipway.
Advantages of outdoor equipment:
The downside is the inconvenience of taking measurements. individual elements body and its general geometry.
Used here metal carcass, on which the machine is fixed by means of chains. Despite the fact that such stocks are used when correcting not too severe damage, structurally frame equipment is more complex. Fixing the body desired height and in the required position is carried out by means of clamps, and the deformed part is straightened by chains connected to a power hydraulic device.
To simplify lifting, auto frame slipways are often used in conjunction with scissor lifts.
The advantages of these designs:
Frame stocks do not take up much space, however, serious deformations cannot be corrected with their help, since the number of exhaust points is small. Therefore, it makes sense to use such structures during straightening and other simple damage.
The most popular platform or frame structures. This is due to the simplicity of their manufacture, compact dimensions and relatively large functionality. Finding suitable drawings on the Internet today is not difficult. The best option- measure the finished factory slipway and focus on its design. Here the main requirement is the dimensions, which must correspond to the area of \u200b\u200bthe workshop or garage. The recommended dimensions of the slipway are 4.5 × 1.85 m. Externally, this is a structure where one frame is inserted into another.
It will take welding machine, hydraulic device, grinder, drill with drills, spray gun or paint brushes. From the materials you need to purchase:
First, the outer frame is welded from the profile, then to finished construction attached to the inner frame. It is necessary to boil from above and below, turning the structure over. Do not forget to use kerchief reinforcements at the corners of the structure to increase its rigidity. If you have doubts about the strength of the frame, weld a pair of cross beams in the middle. When the frame is ready, it is necessary to attach legs to it from below in order to adjust the horizontal position of the device. To do this, you can use bolts 15 cm long and nuts 24, which are welded at the corners of the structure. If you wish, install wheels instead of hardware - you get a mobile slipway. This makes sense if you have a perfectly flat floor or you put the structure on rails that are in a strictly horizontal position.
If it is not possible to purchase ready-made clamping clamps, then they can be made independently from the railway platforms, through which the rails are attached to the sleepers. Cut each of them in half and weld metal on the inside, which, using a grinder, cut into rhombuses. outer side leave it as it is, so that when installed on the thresholds of the car, they outer side was not damaged. Weld a 4 mm thick plate on the inside as well. This is necessary so that the clamping part evenly fixes the threshold and does not warp.
You will need steel 1 cm thick. Cut out rectangles 200 mm wide and 350 mm long. Weld vertical racks 300 mm high to the resulting platforms, do not forget about triangular reinforcing braces made of the same metal. For the manufacture of upper clamps 200 - 250 mm long, it is best to use fragments from KAMAZ springs 1.5 cm thick. You need to burn holes for the mounting bolts in them.
As the latter, use hardware that secures the cylinder head with a diameter of 16 mm. These are strong enough products that do not allow thread breakage. Weld 12 mm reinforcement from the edges - it will guarantee the absence of distortions when fixing the body.
Align the frame strictly on the level to ensure its horizontality. Further:
The last stage is the cleaning of the structure from rust, primer treatment, followed by painting.
Here you can use factory hydraulic devices or homemade mechanism. In any case, the capacity should be 1.5 - 2 tons. To fasten the pulling structures, use an overlay made of a channel and installed on the frame of the slipway. So that the pulling mechanism and chains can be placed at any point, drill holes in the frame around the entire perimeter of the structure.
If you prefer homemade design racks, it is better to use a tower device. Although it is heavier than other varieties, it provides uniform traction over the entire height.
Such a rack can be placed in close proximity to the body, while the power cylinder does not interfere during operation (the rod comes out from behind).
Using a standard hydraulic pump is not The best decision. It is much more reliable to make such a unit from a jack with a lifting capacity of 8 tons. You will have to upgrade the central cylinder, replacing it with a suitable tube. This is necessary to increase the volume of the poured liquid by 300 - 400 ml. In the upper part of the jack, near the fitting, make a breather (you can use a grease gun bent at 90 degrees). And to make it more convenient to work, instead of a bypass bolt, which requires a key, install a “butterfly” that is turned off by hand.
A modern slipway for car body repair is the most efficient equipment to correct the skeleton that received mechanical damage during the accident and other collisions. IN Lately traffic accidents are becoming more and more frequent. As a result, all cars, including even those that have been in a minor accident, need body restoration. We will find out what are the features and advantages of slipway equipment, as well as how to make it yourself.
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
There are 4 main types of body repair tool. There are, as a rule, the following varieties of this machine.
The frame stand is almost the most popular and common type of equipment when we are talking on the execution of finishing manipulations on the body. No view is complete without this stand. restoration work in a professional workshop.
Among distinctive features frame stand can be distinguished by its compactness, because it does not take up much space compared to analogues. Also, it is this type of slipway equipment that is considered very comfortable to use and provides many-sided opportunities.
What is a frame stand? This is a special installation that successfully returns the shape of body elements to their original structure. Without this machine, it is practically impossible to imagine body repair work.
The floor type of slipway equipment is a reliable and high-quality equipment. Its use is justified due to the speed and simplicity of installation work.
This type of slipway equipment is installed on a flat area, and then fixed with special anchor bolt fasteners. No additional installation work is required.
A rolling machine is needed for light body work. IN this case the force exerted by the equipment does not exceed 5 tons.
The sliding type of slipway equipment is not fixed to the floor, it can be easily and quickly used by lifting the car onto the machine. All this can be done by one person. The ideal machine for leveling spars, door pillars and other body parts.
As for the equipment, a hook with 2 fixing points, clamps of 5 and 6 tons, a pneumohydraulic pump with a pedal, stands, etc. should come with the rolling slipway.
The dimensions of a conventional slipway are 350 cm long, 220 cm wide, 20 cm high. The mass of the machine is about 400 kg.
The platform slipway has a reliable fixation system. Thanks to this, it is possible to pull the body into different directions applying different amounts of effort at the same time.
Realizing that the slipway effectively replaces physical strength in stretch, Russian body repair enthusiasts came up with a homemade version of it.
The principle of operation of standard slipway equipment is clear: a car is attached to the frame. The main thing is a reliable fixation, because a positive result of the case depends on it.
High-quality slipway equipment is not cheap. Often for this reason, many amateurs decide to make this machine with their own hands.
First of all, the manufacture of a slipway at home involves the calculation of the necessary components. A drawing is made, the required stock of materials is calculated. The basis of the slipway is a tetrahedron made of an iron profile with a section of 50x50 or 70x40. As for the length, 200 cm is considered optimal, and the width should be equal to the wheelbase of the car.
Stiffener made of similar material - metal profile, is welded in the middle of the platform. Then, as mentioned above, the calculation is carried out, and the amount of the required metal is ordered at the special base or is found in another way.
The slipway is also equipped with good hydraulics. In this case, a kit that can withstand a load of up to 10 tons is suitable.
Depending on what the slipway will be (mobile or stationary), it is equipped accordingly. The stationary slipway should not move, therefore it is not equipped with wheels. A mobile slipway, on the contrary, in addition to wheels, must also be equipped with a device for storing the machine in a vertical position.
The assembly process is carried out by welding. This means that welding skills are a must.
Here's what to do:
Note. Homemade slipway can be assembled at the request of the future owner. It is likely that he will want to strengthen the machine longitudinally or transversely. Therefore, it is not possible to give definite advice on this matter.
It remains only to paint homemade machine, equip it with components for repair and start operating.
