In detail: making a slipway for body repair with your own hands from a real master for the site my.housecope.com.
To carry out body repairs, simple tools are often not enough, and specialized and expensive equipment is required. Deformation of the main parts does not always mean that they need to be replaced. Body geometry restoration can be done in a workshop, but these services are expensive. With the appropriate equipment, you can easily carry out repairs yourself. To perform such work, you will need a homemade 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 vehicle frame and body geometry. Straightening of deformation bends, dents and other irregularities is performed using local loads. In the majority of major changes in the geometry of the body, 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 a high-quality body repair.
VIDEO 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 only suitable for work in large service centers. There are also more mobile options that can be installed in a garage or similar space. When buying such devices for personal use, their price will be high and self-production is most expedient.
Body deformation can occur for various reasons. Accidental collision with an obstacle, a coup while driving on rough terrain or getting into an accident does not go unnoticed for the car. Changing the geometry on the side members or a curved car frame can lead to the following consequences:
Video (click to play).
The presence of noise and extraneous sounds when the engine is running;
Inability to open doors, luggage compartment or hood;
Car skidding when driving in a straight line;
Slots in body panels and structural elements;
Uneven rubber wear.
Such features of damage to the frame call into question the possibility of operating the vehicle. The basic body dimensions are indicated in the technical documentation for each vehicle. Moreover, their change will require the restoration of the original parameters to continue safe driving. Staple mechanisms allow you to almost completely eliminate deformation and the independent creation of such an assistant will be a good alternative to contacting a service center.
The use of multidirectional efforts is the most important feature of the power bench. Such work is difficult to carry out 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 a suitable model of the slipway, one 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 from Trommelberg, Nordberg BAS or Autorobot.
Depending on the nature of the work 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 the large industrial slipway equipped with powerful hydraulic equipment can handle heavy freight transport.To select a suitable 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-turret design of the stand ensure the creation of force in the desired direction. For use in the garage, you can choose only the most necessary equipment, and the rest can be purchased or made later. All slipways can be divided into 3 types with their own characteristics and functionality.
Frame slip - is a structure for pulling relatively small deformations. Such a stand is suitable for carrying out local work and allows you to restore the geometry of the deformed area with high accuracy. The metal frame has a complex structure that serves to provide sufficient rigidity. Strong fixation allows you to stretch the vehicle in any direction and change the direction of the applied forces.
The frame stand is quite popular due to its small size and practicality. The fixation of the machine on such a frame is carried out with special grips. To pull out the deformed nodes, a chain connection is used, which ensures the restoration of the correct position of the damaged part. The set 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 slip - used by professional body repair companies. Its design assumes a fairly high tractive effort, suitable even for the restoration of freight transport. In the absence of the scope of work, this system does not take up much space, which provides additional ease of use. It is quite difficult to make such a slipway for body repair with your own hands due to the huge number of parts. In most cases, the functionality of such a power stand is not needed in an ordinary garage.
Any floor slipway needs a specially prepared base. The installation of rails, uprights, anchors and fastenings requires accurate calculations and the availability of appropriate equipment. The most convenient floor slipway is when installing fastening systems flush with the floor, which will ensure the safety of movement and work. The capabilities of such a power stand will be sufficient to access any deformation area, and the installation and fastening of the machine does not take much time.
Platform slipway - has some similarities with the flyover structure. 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 tremendous opportunities for installing additional equipment. It is most convenient to carry out pulling on such a stand, and its functionality is sufficient for professional use or for repairing in a garage.
For self-production, such a design does not provide any difficulties. Any platform slipway surpasses the frame slipway in its capabilities and is suitable for most types of vehicles. One or more tower racks can be used to repair the machine on this stand, which will be enough for the most difficult work. The pulling force of the hydraulic equipment is not limited. Moreover, such a platform can be used for body repair of SUVs and heavier equipment.
The slipways are produced by large world-renowned companies and small regional enterprises. The price of such power stands varies greatly, but the independent manufacture of such equipment will cost many times less. 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 tools.
To assemble a homemade slipway, you will need a metal profile, which will make up 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 a power rack mechanism, chains and gripping devices that are difficult to manufacture. Before starting work, the metal should be prepared by cleaning it from rust, degreasing and priming. Then you can start assembling the structure.
VIDEO
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 slipway metal should not be less than 4 mm. The platform structure of the straightening stand is most convenient for installation in the garage, and its design should be given special attention.
The exact dimensions of the slipway depend on the type of vehicle in need of service. In length for such a structure, a 4.5 m profile will be enough, and a width of 2 m will ensure convenient installation of the machine. 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. Considering that the load from the power tower on the profile will try to unfold it, it is required to install powerful stiffeners. The assembly of the frame is carried out using welding tacks, and after adjustment, the final welding is performed. In general, all actions are in the following order:
Assembling the structure according to the developed scheme;
Welding the body of the slipway taking into account all stiffening ribs;
Assembly and installation of fasteners for fixing the car;
Installation of power rack and additional equipment;
Installation of chains, grabs and brackets.
When performing such work, special attention must be paid to the rigidity of the structure. It is possible to organize repairs on the slipway only on condition that the machine is securely fastened. You should be careful about safety issues. The loads acting on the vehicle frame during stretching can not only damage the car, but also cause a significant impact on 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. It is quite simple to understand how to make a slipway, and the correct choice of material will help reduce the cost of creating it. To embody your own ideas, you should take all the best from the existing models. The operation of the slipway is designed for many years and such equipment will more than once prove its practical benefits.
Car maintenance is a very costly business: you need to change consumables, carry out maintenance, and also there will be periodic repairs of various parts of the car. It is much more profitable to improve your car, change parts and fix something on your own. Therefore, your garage should have the necessary equipment and tools. Among such devices, an important place is occupied by the slipway for body repair. This device can be made by yourself.
There are three types of slipways: frame, platform and floor. There are also different devices for the type of movement: rolling and mobile.
Frame-type devices are made of a metal profile. The work is performed in a fairly simple sequence:
clamping mechanisms that fix the car;
a chain connected to the power mechanisms is attached to the damaged place of the machine;
with the help of a slipway, a section is pulled out and given its original shape.
In order to safely load the vehicle onto a frame-type structure, a lifting device is needed. The frame slip allows for different types of body repairs, but for difficult jobs, this is an unreliable design.
The platform slipway is used for the most complex body repairs. The metal platform is equipped with a sophisticated system of fasteners and clamps. She also has a scissor lift and towers that perform power manipulation. Such platform equipment is considered universal. It makes it possible to stretch the damaged fragment in all possible directions in order to return the correct shape. Since the device has a variety of mechanisms and all kinds of fasteners, you can carry out different types of car repairs. But the disadvantage of this design is the huge dimensions of the device.
The floor slip is most often used in the professional auto repair industry. The movement takes place on rails. The complete set includes:
system of fasteners, clamps;
metal racks;
rectifiers are pneumatic.
This type of device is suitable for the repair of cars and trucks. In addition, a car of any level of damage can be repaired using such a device. This equipment is very durable and reliable, as it has a large number of components.
In order to equip a slipway for body repair in your garage, you should spend a lot of time. We need a wide range of tools and metal rectangular profiles, section sizes 50x50 or 70x40 centimeters. On the Internet you can find instructions and drawings for making a floor or frame slipway.
The type and dimensions of the structure are matched to the make and model of your car. Since there is work to be done with metal, a welding machine is needed to make the connecting seams. For various operations, it is necessary to select the optimal operating mode of the device. In order for the structural strength to be the highest, it is necessary to rationally combine the transverse and longitudinal frame elements. In the corners of the structure, parts should be welded, the dimensions of which are 25 centimeters high - metal racks.
At the next stage of work, auxiliary mechanisms are made. A fastening system is being developed to secure the vehicle to the equipment. The most important thing is to make fasteners in which the height changes. The design of these mechanisms is selected for specific working conditions and your car:
moving the car along the frame and fixing the car at various points;
fasteners that exert a deforming force;
the system of the most firm fixation of the car on the device.
Another important piece of equipment is the power rack. It must move and work at various points on the slipway. Such a device applies the main force to the deformed parts of the machine, and they are aligned. Such struts are firmly mounted to the base of the structure and must have a high level of strength. In the place where the part is welded, the element is reinforced with an additional metal gusset.
In addition to these mechanisms, it is also necessary to make several thrust rods with strong fasteners. They help when dealing with minor damage to the car body.
Having found a drawing in order to make a slipway with your own hands, you need to prepare the tools:
Metal profiles for the base of the structure;
Longitudinal profiles for posts;
Metal corners;
Welding machine;
Nuts and bolts;
Fasteners;
Primer;
Powder paint;
Spray gun;
Hydraulic device;
Powerful chains;
Hooks;
Blueprints.

So, when everything is ready, you should start making a slip for body repair. All parts must be degreased in advance, covered with a primer, and then painted with powder paint using a spray gun. Then the metal corners must be welded to the profile, which will be the base. Next, the longitudinal profile is welded as a rack and bolted. Then power and retractable devices, chains and hooks are mounted. After you have built the slipway, you need to test it and check the action of each device.
The repair process is quite simple: the extraction mechanisms are started, and the pressure of the power devices activates the slipway. Thus, you can independently repair damage of any level of complexity in your car.
A modern building berth for car body repair is the most effective equipment for correcting a skeleton that has received mechanical damage during an accident and other collisions. In recent years, road traffic accidents are occurring more and more often. 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 me? 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! Read more"
There are 4 main types of body repair tool. There are, as a rule, the following types of this machine.
Equipment called "frame stand".
Floor type of slipway equipment.
Sliding view of the slipway.
Platform type of slipway.
The frame stand is almost the most popular and widespread type of equipment when it comes to performing finishing manipulations on the body. Not a single type of restoration work in a professional workshop can do without this stand.
Among the distinctive features of the frame stand, one can single out compactness, because it does not take up so much space in comparison with its counterparts. Also, it is this type of slipway equipment that is considered very comfortable to work with and giving multifaceted opportunities.
What is a frame stand? This is a special setting that successfully returns the shape of the body elements to their original structure. Without this machine, there is practically no way to imagine body repair work.
The floor type of slipway equipment is a reliable and high-quality equipment. Its use is justified in view of the efficiency and simplicity of installation work.
This type of slipway equipment is installed on a flat area, and then fixed with special anchor bolts. No additional installation work is required.
A rolling machine is needed for light bodywork. In this case, the force exerted by the equipment does not exceed 5 tons.
The rolling type of slipway equipment is not fixed to the floor, it can be used quickly and easily by lifting the car onto the machine. All this can be done by one person. Ideal for aligning side members, door pillars and other body elements.
As for the equipment, a hook with 2 fastening points, clamps of 5 and 6 tons, a pneumatic hydraulic pump with a pedal, stands, etc. should go with a rolling stock.
The dimensions of a conventional rolling stock are 350 cm long, 220 cm wide, 20 cm high. The weight of the machine is about 400 kg.
The platform slip has a secure fixation system. Thanks to this, it is possible to pull the body in different directions, simultaneously applying forces of different magnitudes.
Realizing that the slipway effectively replaces physical strength in stretching, 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 the 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, making a slipway at home means calculating the necessary components. A drawing is made, the required stock of materials is calculated.The base of the slipway is a square 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.
A stiffener made of a similar material - a 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 a 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 kind of slipway will be (mobile or stationary), it is equipped accordingly. The stationary slipway should not move, therefore it is not equipped with wheels. The movable slipway, on the other hand, in addition to the 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 required.
Assemble a rectangle from the profile, and then reinforce it in the middle with additional material.
Note. A 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 definitely give advice on this matter.
At the corners of the machine, heights are welded to prevent the vehicle from moving off the slipway;
Clamps are installed on the longitudinal sidewalls of the frame;
A power stand is installed in the shape of the letter "L", which can easily move and be fixed anywhere in the frame.
It remains only to paint a homemade machine, equip it with components for repair and start operating.

In case of severe accidents, the car receives body deformation. A defective housing affects fuel consumption and handling. A body with a broken geometry will not be able to protect passengers in the event of a repeated accident. A body repair slipway is a necessary tool for repairing a car.
The body straightening jig is a device for carrying out body repairs. The stand is designed to straighten out serious damage to a car, and is equipped with fasteners that allow you to pull the body, as well as change the shape and size of some elements. A slipway is used to repair serious damage to the car body.
All types of slipways have an identical operating principle. To eliminate the deformation of the body, it is fixed to one or more areas that need to be straightened and straightened. Further, the master, using the drafting device, applies force and straightens the damaged parts of the body.
Simple slipways for body repairs are equipped with one exhaust device. Complex fixtures have several exhaust mechanisms.
There are 4 types of devices: floor-standing, rolling, frame and platform.
The rolling stock is used for body repair of various types of cars. It is equipped with devices that allow you to secure the car without flanging the sills. Rolling slipways are convenient to use in confined spaces. Due to this, the device is used in garage conditions.
Rolling equipment must not be used in the event of distortions and changes in the body geometry.
Do-it-yourself floor slip for body repair is a compact and effective equipment for restoring a car body in a garage or workshop.If there is no need to use a pulling mechanism, then the rails are used for other purposes.
The frame slip belongs to the professional type of exhaust mechanisms. The main difference from other types is that frame fixtures have a complex design.
The exhaust mechanism allows you to repair different car models. The machine is fixed to a frame that is highly durable. With the help of a force directed in different directions, the body deformations of mild and moderate severity are pulled out.
To save space in the workshop or garage, as well as to facilitate the process of restoring the car body, they purchase body repair stands equipped with a lift.
The platform slipway for body repair is a complete professional equipment. Devices of this type are used to straighten damage to the body of any car, including frame SUVs.
The design of the pulling mechanism consists of special rails and an entry bridge-base. The car drives into it on its own, or it is pulled in there if the car is not on the move. The platform is equipped with various devices and fastening mechanisms that securely fix the vehicle on the slipway.
Platform devices have hydraulic metal stands, a winch, power and pull-out units. The beams of the device allow you to effortlessly move heavy structures in any direction. The platform leveling stand has a telescopic scale, with the help of which accurate calculations and measurements are carried out.
The disadvantages of the platform exhaust mechanism include large dimensions and high cost of equipment. It is used in large car maintenance services.
Making a homemade body straightening slip will save you money as they are expensive. When designing, you should take into account the dimensions of the future fixture for car repair and create a drawing of the device. It can be ordered from specialists, or you can find it ready-made on the Internet. Depending on the type of the exhaust mechanism, the set of tools and materials that will be needed differs.
To make a mobile body straightening device yourself, you will need:
From a profile with a thickness of more than 4 mm, you need to create a frame with dimensions twice the dimensions of the machine.
The structure is reinforced with cross members and corner pieces. The cross members will fix the car. Exhaust mechanisms are also attached to them.
To make the structure mobile, four wheels are attached to the bottom.
To be able to lift the car onto the frame, a gangway is constructed. On the one hand, they will have a special plug, and on the other, a removable section necessary for lifting the vehicle.
The design is equipped with a bench vise or special clamps. They are needed to securely fix the machine.
VIDEO
In order for the structure to serve for a long time, it is covered with a layer of primer and painted.
When designing a straightening stand with your own hands, the channel is concreted, and also reinforced with cross members of a rigid structure. The optimal material for creating a "stationary" is a metal profile with a section of 40 by 80 mm. The length is determined depending on the dimensions of the vehicle.
Further, along the perimeter of the frame, four fasteners are installed, which are designed for the vice clamping the machine. They move perpendicular to the channel, thanks to which damage of any size can be repaired. The car is installed on a body repair stand using a jack: first, the front of the car is raised, then the rear. In the garage or auto repair shop, you will need to mount the special eyes required to attach the chain.
To facilitate the process of raising the car, a homemade lift is used. It is done using a winch and a special platform.
A slipway is a necessary equipment for do-it-yourself body repair. The device removes damage to the car body. When self-restoring the machine body, the exhaust mechanism is also necessary.
On our forum, and on the forums of our friends, auto repairmen, questions about the manufacture of a slip for body repair in our garage constantly pop up. Many people try to do it with their own hands, but sometimes new knowledge is required, solutions to possible mistakes, and you have to look for help from your colleagues.
Usually, two versions of homemade slipways 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 an 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 member of the forum Yevsey.
The design of the light and mobile Finnish slipway Autorobot micro A was taken as a basis.
The main materials used in the manufacture of steel are channel # 10 and # 12.
Below in the photo are the main nodes of the slipway.
An 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. The width of the sill grips is 150 mm, the tightening bolts are 12 mm, and the bushings are 14 mm. The springs were used from the classic Vase valves. The jaws of the grippers are made of a metal rasp.
To work with this slipway, hydraulics from a set designed for 10 tons are used.
And here is the actual scheme itself with the dimensions of the slipway.
To simplify the work, special stands were welded with the car entering them in front or back, and it became easier, as well as much faster, to bring the slipway under the belly of the car.
This construction of the slipway has the ability to put an adaptation to pull it down. To do this, you need to modernize it a little by placing a slide 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.
There are only two sill grips and there is no height adjustment.
The lock for turning the boom horizontally: there was iron 5 mm, you need at least 10-15 mm.
During operation, weaknesses began to emerge, which were strengthened.
The length of the telescopic boom is in principle excessive, so it can be made shorter.
How to hook the car to the thresholds from below with these grippers if they do not have a flange, for example, a BMW type car? To do this, you will need special adapters that cost quite a lot of money (there are homemade options).
Both a plus and a minus can be considered the mobility of the slipway and the ability to turn it in different directions, but in a small garage, there will be a problem with movement.
General impressions of Evsey (the author of the project) from working with his slipway:
In general, beauty, the car is dead on the slipway, the hydraulics pulls extremely easily, as if you were 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, rated 5 plus, very mobile and reliable.
You can read the details and discussion of this design on our forum here.
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.
VIDEO
In the second video, the mistakes that were already revealed during the work, how he fixed them and what alterations he made.
VIDEO
And now, we smoothly moved on to the stationary slipway, or, as it is also called, the floor one.
If I had originally built this garage for body repair, then I would have concreted the channels along the entire length of the inspection pit, and to these channels I would have anchored the grips for the sills of the car. And the traction boom would also be attached to the anchor fasteners.
What is the most important thing in the slipway? The most important thing is that it is possible to securely fix the car and even then it can be pulled in any direction, of course, if the construction of the slipway allows.
I cannot offer any 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 it was made according to the principle of his vision of the situation (tasks to be solved, source materials, garage size, finances and other "wishes").
Basically, these are channels welded and embedded in concrete with a cut for fastening various devices (grips of thresholds, "tower").

The idea of creating the slipway was taken from the Internet, in particular from Vitaly Kakhovka. Sizes 4.5 by 1.85. Why is this? Because it is a normal size. And the point. One of the biggest advantages of this slipway is that it can be put in a standard garage, or any other room in which it fits. Unlike similar slipways of frame construction, this slipway does not have the so-called "geese" (as in the photo), which increase the working area both in front and on the side by a sufficiently large distance, which does not allow using such a slipway in a regular garage.
For the manufacture of the slipway, 46 meters of the 16th channel were purchased. Moreover, they managed to find half at the reception, which made it cheaper by a few sput. 20 meters were purchased at 25 rubles per kg.at the reception of ferrous metal, and the rest was bought at a metal base at a price of 570 rubles per meter.
The channel was immediately marked and cut to size.
The length of the outer ones is 4.5 m. The length of the middle ones is 3.76 and the length of the bridges is 1.5 m.
After welding all channels into blanks, in the form of boxes, half of the blanks are set aside. We lay out on the floor the outer contour of the slipway from boxes 4.5 meters long (namely, this is the length of the slipway) and internal, more precisely perpendicular boxes 1.5 meters long. I set the horizontalness with the help of a level, putting under the boxes the thickness of wood chips or metal scraps that was required. Also, before welding the first outer contour of the slipway, the diagonals were measured with a tape measure several times. After that, the boxes were welded (with tacks at the corners and center, as well as at the inner corners and centers) to form a rectangle.
We do the same with the other side.
Why 6 and not 4 or 8? Do not know. I decided that I shouldn't do less and more. And the longitudinal blanks - the boxes were already measured and cut off exactly for this gap, as planned. Then we repeat the procedure of turning the future slipway 180 * again and scald the lower part. Then turn it over again and brew the upper part.
After that, we insert the inner longitudinal boxes and, also stepping back 6 cm from the outer boxes, grab them in the newly welded transverse boxes.

The process is repeated one more time. Turn the slipway 180 * and scald. Then turn it over again on the front side and scald it completely. (The vertical walls were also scalded in a horizontal position, because I cannot boil the vertical seams with high quality). What am I doing this for? Moreover, in a couple of days the slipway was lifted up and down by a winch many times. Although it was probably worthwhile before that to make something like a rotating platform on 2 bases. It would make it easier. Anyway. The slipway is welded. What is a slipway without legs? Nope, this is some kind of legless horse, and you won't be able to fix anything on it. For the legs, I decided to use nuts, the largest that I found in the store. I don’t remember, probably 24. Well, with them bolts, 15 cm long, for future adjustment of the slipway in relation to the horizon. The nuts were welded at the corners of the slipway.
We begin the manufacture of devices for attaching a car to a slipway, as well as for pulling and pushing.
I made the clamping jaws before welding the slipway. I can’t advise you to make just such, because I haven’t pulled a single patient on my “operating table” yet. I hope they won't let me down. I made them from 2 railway platforms for attaching rails to sleepers. Having cut it in half, I welded half of the old Soviet file to each file. On the inside I welded dots on the camping ground, which I then turned into rhombuses with the help of a grinder.
For the manufacture of racks with clamps, on which the clamping jaws will be welded and on which the car will be installed, as well as devices for extraction, clamps and hooks, metal was purchased on a metal acceptance with a thickness of 10 to 20 mm. For the manufacture of racks (let's call them paws) I used a centimeter metal, cutting out from the acquired platform with a width
The cross braces were cut from the same metal.
After welding the 2nd vertical post to the site, I realized that it was not worth cooking like that, because the site itself was bent from welding. Then I had to unbend the platform with a sledgehammer, placing wooden blocks under the edges, and lower the vertical stand between the slipway boxes (although the slipway had to be lifted and placed on wooden blocks so that the stand did not reach the floor). But to be honest, it didn't help much. I had to weld their lower platforms with potholders together, holding them with clamps and
Then, from the separately purchased KAMAZ (15 mm thick) fragments and scraps of springs, the upper clamps were cut, 20-25 cm long, with a slight offset from the center, holes for KAMAZ bolts were burned out in them
The next step was to weld the body clamps to the struts. There is no photo, but I will try to explain.
First, the ready-made racks were bolted to the slipway, which had been pre-leveled. I screwed them into approximately those places on the slipway, on which they will subsequently stand. Clamping all 4 paws, the level measured one height, to which the clamping jaws were welded, which were first tightened with clamps, tacked by welding, and then, after removing the paws from the slipway and laying them in a horizontal position, they were scalded to the paws from all sides.
The dimensions of my paws are indicated above, the width of the jaws was taken arbitrarily, that is, based on the availability of material, and as I already wrote, the clamps were made of railway platforms and welded halves of files. Bolts for clamps 16. The holes in the jaws, previously, temporarily tacked by welding at the ends to each other to maintain alignment, were drilled on a drilling machine. But once again I want to draw your attention to the fact that all sizes are arbitrary and were taken on the basis of keeping as little scrap as possible from the available metal. I think that sponges can and should be made with a width not less than mine, but better than a larger one. The bolts and, accordingly, the holes for tightening the jaws may need to be larger and their diameter should also be larger.
