The use of a mini lift in the garage will require the efforts of several people, as a result of which the side of the car may be knocked over. Few dare to repair the car at a strong angle, but in the absence of other methods of exit is not provided. It can be made by using corners with a cable mechanism from an old winch.
The cost of the finished car lift is high, however, a self-made version can damage the person working under it if the design is unreliable. The weight of the car should not exceed more than a ton; if the structure falls on a person, you can get irreversible injuries.

A homemade car lift is made according to prepared drawings, or versions of finished products are used. In the latter case, one has to rely on the author's high computing skills. Incorrect calculation of the base or one of the fastened nodes can lead to irreversible consequences, in the best case, damage to the unit being lifted.
For a self-made kit made by hand, you will need parts and assemblies, without which assembly is impossible. You can find this type of component in large stores selling construction equipment. If the funds for new parts are not enough, it is necessary to go to scrap metal collection points and enterprises that write off old parts.
Vehicle parts are subject to wear and tear. For this reason, in a private garage, a lift for a car, which can be assembled from available tools, comes in handy. Aggregates manufactured by different companies often have a high cost, so a jack assembled in our own workshop will help to quickly repair the machine without unnecessary financial investments.
The most economical option for a household lifting mechanism is a two-post unit equipped with an electric, electro-hydraulic or hydraulic drive. In the hoist with the first type of drive, the racks accommodate threaded shafts with a moving bearing nut fixed on a lifting steel arm. There are other models of the screw design, which include 1, 3, 4 racks.
To assemble a cheap but productive device for your own use, you need to understand how a factory-made device works. You can make a do-it-yourself car lift for a garage from the following components:
3 steel corners 750 × 750 × 8 mm;
worm gear;
steel plate 10 mm thick;
2 chains with large thin links made of wire with a diameter of 30 mm;
hook;
cable 5 mm thick;
two sprocket keys.
When choosing the constituent elements, it should be borne in mind that the minimum carrying capacity of the unit with a gear ratio of 60 kg should be 300 kg.
A homemade lift for a car service workshop is assembled quickly and easily. The workflow consists of 8 steps:
steel bent corners must be fixed on opposite flat walls of the room so that the hood of a car is under them;
it is necessary to install a steel plate on the corners and fix it with M8 bolts;
install a reducer on the plate;
fix the key on the drive shaft reducer;
drill a hole in the plate and pass the chain, close in the form of a ring;
fix the smaller key on the output shaft of the gearbox;
drill two holes in the plate, skip the second chain;
Fix the first end of the drive chain on the small key, and the second end with a hook.
Using professional drawings, a do-it-yourself scissor lift can be made very easily and quickly. The homemade garage lift has a scissor-shaped linkage system. The working moments are carried out by a hydraulic drive powered by an electric motor.

In the process of assembling a structure, the master may encounter a number of safety problems. The correct choice of material for the component parts will help to eliminate the fall, deflection and breakage of the jack.
In the manufacture of equipment, a locking mechanism should be installed, with the help of which a self-made car lift holds the load in the event of an emergency. Inspection and maintenance of the threaded shafts, bearing nuts, hoses and cylinders should be carried out periodically. Setting the operating parameters of the device is carried out as follows:
remove the fasteners securing the frame and the car engine;
bring the cable under the motor, throw the loops onto the hook;
fingering the chain, pull the cable, slowly raise the load to the desired height;
move the engine to the repair table.
If it is not possible to equip an inspection pit with a lift in the garage, mechanics recommend arranging a tipper-lift for a car with your own hands. Installation drawings are best ordered from a professional. A fixture is made of sheet metal and a square profile by welding. The lifting structure is robust, safe and easy to operate.
VIDEO
As the main working unit, the auto-lifter-tipper contains a rack, hydraulic or worm-gear jack. The heel of the device with large stiffening ribs can tilt a car weighing 2.5 tons by 45 °. For strength, the platform of the device with movable mechanisms is equipped with stiffening ribs up to 7 mm thick, corners and a square thick-walled profile. A support bent corner, a lower platform and a support bar are also made of metal.
A mechanical tipper can be made from a set of necessary components:
thick-walled square pipe 0.5 × 0.5 cm or a corner with a shelf;
two fingers;
four bushings;
fragments of metal for kerchiefs.
The parts are fastened together by welding, the brackets with hinges are connected to the platform, after which the lift is ready for work.
For a private service station, an inexpensive and efficient hydraulic scissor lift is ideal. Having the structure at his own disposal, the owner of a car gets the opportunity to carry out repair and maintenance work on the body, replace the chassis, suspension, brake pads and transmission parts. You can make a lift with your own hands using a specially developed technology.
For small rooms, garages, auto repair shops, many people install a hydraulic lifting mechanism.Now some craftsmen make a scissor lift with their own hands.
Let's consider how to make a car lift. This device is used to fix the car and raise it to a certain height in order to provide access to the chassis, suspension, machine mechanisms.
First, choose a lift scheme. The most popular fixtures are with 2 posts. This design can be electromechanically driven. There are designs with several posts, they distribute the load better. The scissor structure is a platform with a leverage system.
This device may have an electromechanical drive that will transfer the load. It is necessary to make a homemade lift taking into account that the device is safe and reliably holds the car. It must be borne in mind that when performing work, the foreman will be under the machine, the weight of which exceeds a ton.
Before making a do-it-yourself scissor lift, drawings and design diagrams must be drawn up. The drawing should indicate the dimensions of all parts and show the places of welding of units and systems of the structure being created.
Instructions for making do-it-yourself scissor car lift structures:
First, supports are created using steel corners, which are hammered into a solid wall.
A 1 cm thick slab is installed on these corners and fixed with bolts.
The load will be transferred through a hydraulic cylinder system. Nowadays it is easy to find such mechanisms, as they are used in different devices.
Holes are made in the slab for the chain, then it is threaded in and closed.
A key is installed on the gearbox shaft.
Then a sprocket is installed on the output shaft, which is suitable for working with the chain.
In the plate, 2 holes are made for the passage of the chain, at the end of which a steel hook is installed.
The resulting structure can be used in a private garage to lift a small car. The lifting device will allow you to independently inspect and repair the chassis of the car and other mechanisms and systems.
People often assemble the lift themselves because a new factory design is expensive. It should be borne in mind that making a homemade lift is not always an easy task. In addition, if the structure is not assembled correctly, then its use can be dangerous.
An installed vehicle falls off the device if:
the weight of the car indicates the load that the homemade lifting unit cannot support;
the fixing mechanism does not work well;
the supporting device cannot withstand the existing load;
the self-made device has the supports incorrectly installed, or they are loosely fixed.
Also, difficulties in creating a device arise because some structural elements cannot be performed without special equipment. For example, it is difficult to manufacture long lead screws. Therefore, it is rather difficult to independently carry out this design. Many craftsmen make a tipper for a car instead of this device, since it is easier to manufacture.
When creating a fixture, most of the parts will need to be bought in stores, so the final cost of the finished device can be considerable.
In addition, an accurate calculation of all nodes will be required, which only an engineer with experience in performing such work can do. If you do not have such knowledge, then you will have to order a project with all calculations in a special organization, which will require financial costs. If an error is made in the calculations, then the device will not be able to withstand a heavy load.

Therefore, if you are not sure that you can make such a complex project a reality, it is better to create a tipper for the vehicle that is safer.

Car lift scheme
Sometimes a lift is needed to inspect or repair the underside of a car. Of course, you can contact a service station, but craftsmen who repair their car themselves can make a lifting mechanism for themselves in the garage. We will learn the principles of operation of lifts and their design features, as well as how to independently make a lift and operate it correctly.
A car lift is a special technical equipment that is used to carry out repair work and maintenance of vehicles by lifting and holding it at a certain height.
Depending on the installation method, lifts are:
stationary;
mobile (mobile);
portable.
Depending on the type of lifting mechanism, they are divided into the following types:
mechanical;
pneumohydraulic;
hydraulic.
By drive type:
manual;
electrical;
powered by a car engine.
For your garage, you can make a pit lift yourself, which will be convenient to use. Such a lift has a safe design, which is important for homemade products, and is also easy to operate.
The height of our homemade construction will depend on the hydraulic jack used to lift the top, and the length will depend on the width of the garage pit. The carriage of the elevator will be 35 cm high and 80 cm wide for the pit of the corresponding size.
It will be equipped with rollers that are located along the width of the pit and will move this entire structure along the length of the pit. When manufacturing and installing the lift, it should be borne in mind that the edges of the garage pit must be trimmed with corners on which the rollers will walk.
Therefore, the selected rollers must withstand a large weight and move freely along the corners set along the length of the pit.
In order to make a structure for lifting the machine, you should stock up on the following materials:
channel 100 mm - 1.5 m;
corner 63 mm - 2.5 m;
corner 50 mm - 2.5 m;
square steel pipe 40 mm - 0.6 m;
square steel pipe 50 mm - 0.5 m;
Video: making a car lift with your own hands
If you have taken into account all the important points in the ratio of the width of the pit, the height of the jack and the dimensions of the structure itself, then the lower part of the channel should freely sink into the pit, and the rollers on the upper part should be located along the width of the pit and move along the corners set along its length.
On the lower part of the channel in the middle, a hydraulic jack is installed, which, if necessary, starts up and raises the upper extendable part that raises the car. There you can also store special attachments for the feet used as extension cords.
When using a lift, usually do the following:
The guides should be lubricated, for example, with grease for better extension from the lift. The condition of the lubricant should always be monitored and refilled as necessary.
Extend the share to the required distance and insert the machined share with the required extensions into it.
The vehicle to be lifted must be secured with the handbrake - make sure of this.
The jack must be tightened and the rise to the desired height is made.
It is permissible to go under the car only after stopping the work of the lift.
It is forbidden to stick your head or limbs between the sides of the lift.
Do not put your hands or fingers near the rollers.
Before starting work, it is best to sketch out a diagram of the future product. The first step is to draw drawings of the base from the channel, the length of which is equal to the width of the pit (you can minus a few cm).
The height of the channel structure and its sides must not be lower than the jack used. The rest of the details need to be planned and drawn based on these main parameters.
It is important that the rollers attached to the side corners fit exactly into the corners of the pit. Another important point will be the exact insertion of 40 mm square pipes into 50 mm square guides welded to the side channels.
If you have experience in welding and manufacturing metal structures, then it will be quite within your power to independently make a convenient pit lift for your garage. This will help save your budget and make the product exactly the size of your inspection pit in the garage.
No auto repair shop is complete without a car lift. The equipment is available on the market in a wide variety of models from local and foreign manufacturers. A car lift installed in a car service will pay off quickly, but buying a car lift for personal needs is a stupid expense. Moreover, it is realistic to build a car lift with your own hands.
The owners of personal cars are well aware of how rapidly the prices for the maintenance and servicing of such vehicles are rising annually. A sensible solution would be DIY car repair when qualifications and experience allow it. A separate tool is already in the garage of motorists, but the situation is different with the pit repair room and equipment. However, some important devices (for example, a car lift for a garage) you can create yourself.

Before choosing a drawing for a future lift, it is worth analyzing the existing equipment versions and choosing the best one for your garage. Lifts are:
single-column and double-column;
hydraulic;
rack and pinion;
pneumatic;
screw.
The advantages of the single-post variants are their compact size - perfect for small garage applications. A two-post lift will provide an opportunity to carry out repair work of any level of complexity. The hydraulic truck crane is practical. It is necessary to observe the level of fluid in the oil seals. Rack lift has a simple design and protection of parts from contamination. For the efficient operation of a pneumatic crane, you need to buy a pump. And the screw version is characterized by low lifting capacity and lifting height, therefore it should be considered the latter.
VIDEO
Your future homemade car jack must have a certain design. The two-post mechanism (electromechanical or electro-hydraulic options available) is used everywhere. The first consists of a threaded shaft with a bearing nut. The shaft rotates by means of an electric motor with a gearbox.
In the second case, the shaft is replaced by a hydraulic drive. And also a scissor lift has proven itself well in business. Special levers act as "scissors" and. The lifting of the load is carried out by hydraulic drives with electric motors. Each design can be tailored to your specific application. Any considered installation turns out to be quite difficult to build a similar car lift for a garage with your own hands. Indeed, even when creating a motor-lift, difficulties arise, but here the task becomes much more complicated.
VIDEO
You must be prepared for the fact that the creation of a useful system (homemade lift to the garage) will be fraught with significant financial costs and difficulties in manufacturing. But the main thing is the need for strict adherence to safety rules. Among them:
elimination of the risk of injury during work on the manufacture of the device;
provision of a stock of equipment carrying capacity;
creation of locking mechanisms.
The last point deserves special attention, because such devices will protect against the consequences of emergency situations. Better to anticipate them and regularly check the condition of the shaft and nut when electromechanical drive, and for electro-hydraulic equipment it is important to check for damage to cylinders and hoses.

To avoid costs and a lot of complications, you can give preference to a simple garage lift-tipper. The device will allow you to tilt the car to one side, and the tilt angle can vary from 45 ° to 60 °. This will be enough for most renovation work.
To build such a unit, you will have to create and connect a number of parts: the front pillar, the beams (top, bottom, rear), and the shoe. Various connectors will also be required. It will take a lot of work with metal therefore, it is necessary to have special tools - welding, grinders and drills with a set of drills for metal. The main material for work is 4 mm steel sheets, corners and bushings.
VIDEO
It is worth starting the manufacture of a jack from the base - a shoe. It is necessarily made of steel and in full compliance with the drawing. It is important to achieve free movement shoe on the front pillar in the vertical plane. The stand consists of two squares that are welded from 32 corners with a minimum length of 1500 mm. They are united by means of corner segments, and the distance between them should not impede the free movement of the upper beam. After that, you need to drill holes for the support pipe and fingers - the metal clips of the upper beam and shoe.
VIDEO
Next, proceed directly to creating the upper beam. For her, take two corners of 1.5 m and weld them into a U-shaped profile. It is also necessary to weld a metal insert in the middle, which will ensure the fixation of the jack. The beam is ready when you weld a plate of the appropriate length and height to the profile. The result is a rectangular beam. One end of it must be tightly welded - the bushing will be attached to it and the rails for the jack are welded to the other end.
The platform for the beam is created from sheet steel. You can bend its sides to get the semblance of a box, or weld the walls of this very structure. Inside the site there will be a piece of wood of the required size, which is fixed with fasteners, and rubber is mounted on top of the tree. The platform is attached to the beam by means of a pre-welded lug.
VIDEO
A rear beam is required for the machine to be supported securely from the opposite lifting side. It is welded from 4 corners 32, 1500 mm long, to end up with a square the length of a car. The beams are interconnected by means of a special assembly on the rear beam. The bottom beam is also created from corners and connected to the upright and rear beam. The only thing left to do is to make stupor fingers and install a jack. The end result is an efficient tipper.

Having your own car lift is not only very convenient, but also beneficial. The benefit from it, of course, does not appear on the second day after the purchase or assembly, but the fact that you can save on minor or even overhaul of the car is definitely.
But we are talking not only about saving financial, but also about saving space in the garage. Plus, even trivial operations such as oil changes or steering linkage diagnostics will no longer be time-consuming and inconvenient. You can buy a lift, or you can assemble it yourself.
Frankly speaking, if you assemble a lift for a car with your own hands, then its price will not differ much from the factory new one, and even more so, used one. For example, a Chinese fork lift of an electromechanical type, screw, will cost 100-120 thousand rubles. If you collect all the elements in pieces, then only the engine, gearbox and power screws can cost 80 thousand, not to mention the power frame, control automation and other structural elements, mainly of a power nature.
It is cheaper, of course, to assemble it yourself, but not radically.Self-assembly has only in some cases - when we are assembling a fairly simple and effective device and when almost all the elements are already at hand, it remains only to tie them together. Be that as it may, there can be only several types of lifts:
Fork screw.
Scissor lift.
Lift-tipper.
The lift is platform.
The lift is plunger.
Platform lift.
We will not consider half of this range, because, for example, a platform lift is too bulky, expensive and ineffective in a small garage, because it takes up a lot of space.
If we have already decided to assemble the lift ourselves, we must make sure that the garage meets certain requirements. Otherwise, we simply will not be able to use the device physically - there will not be enough space. And the height of the car's lift will be limited by the height of the garage, so you shouldn't take on a serious structure if the height of the garage does not exceed the height of the car by at least 1.5-2.5 m.
In addition, at least 1.5-2.5 meters should remain along the perimeter of the lift for servicing the car. This is about the place. If we build an elevator with an electric drive, then the electrical equipment in the garage should be three-phase, since most powerful electric motors are connected to a three-phase network. Basically, the preparation of the site depends a lot on the design of the lift, the size and weight of the vehicle.
One type of garage lift is the engine lift. It will allow you to remove the untied motor from under the hood, even alone. There are also electric winches with a control panel, but we do not remove motors every day, so there is no point in spending hundreds of thousands on a professional hoist. To assemble the hoist, which is shown in the drawing, we need:
Worm gear reducer (7).
Two corners 45x45 (4).
Loopback chain (10).
Lifting chain (9).
Chain sprockets (6,8).
Metal plate 8-10 mm thick (5).
The operating principle of the hoist is clear - the gearbox is installed under the ceiling on a metal plate, which rests on a corner mounted in the walls. In this case, the plate is not rigidly fixed to the corner, it can be moved to correct the position of the hook on the lifting chain 9. A large diameter chain gear with 48-62 teeth is put on the input shaft of the worm gear. A chain of the required length is selected and looped back. Turning the input shaft of the gearbox, we turn the output shaft, on which the gear is put under the chain with the number of teeth 24-28, on which the chain is also hung, but with a hook. At the same time, when positioning the lift, it is necessary to take into account the height of its attachment so that the engine can be completely removed from the engine compartment, and the car could be freely rolled out from under it.
The simplest hoist design is a tipper. We have shown several designs of self-made tippers in the photo, in fact, its design is so simple that it does not require any comments. It remains only to decide on the dimensions of the profiles and their length. As a rule, a 20x20 square profile is used for such a lift, and 40x40 mm for a car weighing more than 1800 kg.
Video (click to play).
The tipper structure is based on the rigidity of the triangular structure. Our task is to change the length of the side of the triangle, while lifting the car to the required angle. For lifting, both brute male power and a jack or a winch, as in the photo, can be used. The adjustable rail is marked and drilled so that you can fix the machine at a certain angle. Such a lift is designed taking into account the size and weight of a particular vehicle. Successful and comfortable work and maintenance of the car for everyone!
