Let’s choose the construction
To make a unit for lifting vehicles with your own hands, it is important to familiarize yourself with the designs on the market. The cost of the finished equipment can be equal to the price of a car. In car repair shops you can find the most common option. a screw two-post jack, the design can be made with a hydraulic or electric drive. The design can be made with additional beams, depending on the anticipated loads.Scissor elevator has a platform and is set in motion by a mechanism similar to scissors. Homemade elevator of this type is driven to work by mechanical force, makes the lifting by the hydraulic drive connected to an electric motor. Before making this type of construction it is important not to forget about safety rules. In operation, the parts can spontaneously lower, resulting in irreversible consequences. Homemade car elevator should be made with a reserve of power aggregate power, when using it is important to know the mass of the lifted element.
In emergency situations with the garage elevator, you can hold the car locking mechanisms. To avoid critical moments, it is necessary to check the condition of the electric motor and hoses. The main problem of making a screw elevator with your own hands is the complexity of assembling and making the mechanism. Hydraulic parts are expensive, it is not reasonable to buy a new construction.
The modification of the mechanism, which allows lifting the car from a certain side, will do for garage use. Your own hands may produce a hydraulic elevator, which raises the car at an angle of up to 60 degrees, such a design is called a tipper.
The size of the garage: what affects them?
What size garage to do? First of all, you need to know and understand the factors that determine the size of the construction of the garage, what restrictions exist on its maximum or minimum dimensions. The first factor. the size of the garage plot and where the building is located. If the garage is in the cooperative, it is particularly unraveled, most likely, you have at your disposal the standard size of the garage.
Another thing, if you live in the country or in the private sector, there the size of the garage on the site you choose yourself.
Here at this point comes the second factor. the length, width and height of your iron horse. Of course, the garage must hold your car and provide comfortable entry, exit and exit of the car. As a matter of fact, this factor should be considered “for the future”. what if you buy a larger car in a few years, and maybe even buy a minibus.
Also on the size of the garage for the car affects the presence in your family motorcycle, bike or snowmobile, because it, too, need somewhere to put for storage and maintenance.
Speaking of maintenance. If you plan to conduct simple repair and maintenance of your vehicles inside the garage. for this, too, need to allocate space, because somewhere to put the racks for parts, workbench, press, toolboxes, etc., etc. Having a small storage area for fuel, lubricants, parts and tools will significantly increase, especially in length, the size of the garage.
And the last, but not least factor. your budget. If it is small, then it is worth thinking about a fairly compact garage-box, whose task is simply to store your car from the bad weather and hooligans.
Otherwise it is better to make the size of the construction bigger. And if the budget is not a problem for you, you can try to spread out and make a room for rest, a platform for two cars, or even a second floor.
Standard size garage for a passenger car:
Pit hydraulic jack with their own hands
Amateur and professional car repair requires specialized equipment, which unambiguously includes a traverse. This highly specialized pit jack is a great help for mechanics at service stations and workshops.
In the domestic segment, this equipment is much less common, and you can find it in the garages of only true car enthusiasts. Professional orientation and. make such an elevator is not the most cost-effective purchase, but if desired, you can make a pit hydraulic jack your own hands, from scraps of rolled metal.
Measuring tools, file, vise and other auxiliary tools, without which the process of such a scope will not do, we will not enumerate. If you decide to take on such a serious project, then you have such useful little things.

As a lifting device, in this construction, any bottle jack of suitable lifting capacity can be used.
All materials and measurements are provided as an example and are not intended to be the absolute truth. Everyone builds to the best of his ability, with what he has and how he thinks it is necessary. This example shows that for this width pit can be made of these elements. Based on this, you can make for yourself, simplify or modernize. It all depends on the skills and goals set.
To improve convenience and increase functionality, you can equip your homemade hydraulic jack with adjustable legs extending from the support platform. As the legs will take the full load, they should be made of a thick-walled profile, from 5 mm, and go into the landing without visible backlash. If desired, you can make convenient grooves for the soft cushions of the stop, from a thick-walled tube or other suitable metal part.

A final review of the pit jack at your workplace, capturing the additional nuances of organizing an exemplary workspace. No less useful information for lovers of the topic.
To avoid the expense and the mass of complications, you can opt for a simple garage tipping elevator. The device allows you to tilt the car sideways and the tilt angle can vary from 45° to 60°. This is quite enough for most repairs.
To build such a unit, you will need to create and connect a number of parts: the front post, beams (top, bottom, rear), the shoe. You also need a variety of connecting elements. You will need to work a lot with metal, so it is mandatory to have a special tool. welding, angle grinder and drill with a set of drills on metal. The main material for the work is 4-mm sheets of steel, angles and bushings.
Start the construction of the jack with the base. the shoe. It is necessarily made of steel and in full accordance with the drawing. It is important to achieve free movement of the shoe on the front pillar in the vertical plane. The rack is two squares that are welded from angle 32 with a minimum length of 1500 mm. They are united by means of pieces of corners, and the distance between them should not prevent the free movement of the upper beam. After that, you need to drill holes designed for a support tube and pins. metal clamps of the upper beam and shoe.
Creating the top beam
Then proceed directly to creating the top beam. For it, take two 1.5 m long angles and weld them into a U-shaped profile. It is also necessary to weld an insertion of metal in the middle, which will ensure the fixation of the jack. The beam will be ready when you have welded a plate of suitable length and height to the profile. The result is a rectangular beam. One end has to be tightly welded. the bushing will be attached to it, and the jack stands are welded to the other end.
Platform for the beam is created from a steel sheet. You can bend its sides to get a semblance of a box, or weld the walls of this very structure. Inside the platform will be a piece of wood of the right size, which is fixed with fasteners, and on top of the wood is mounted rubber. Playground is attached to the beam by means of a pre-welded eyelet.
In order for the car to be reliably supported on the opposite side of the lifted, you need a rear beam. It is welded from 4 angles 32, 1500 mm long, so that the end result is a square length of the car. Beams are connected to one another by a special node on the rear beam. The lower beam is also created from angles and connected to the strut and rear beam. It’s just a matter of making the tines and mounting the jack. The result is an efficient tipper.

Sometimes you need a car elevator to inspect or repair the underside of your car. Of course, you can go to a service station, but craftsmen who repair their own car, can make themselves a lifting mechanism in the garage. Let’s learn the principles of elevators and their design features, as well as how to make an elevator yourself and operate it properly.
It is easy to assemble a device with a three-point shoe with your own hands. In this situation, the base is prepared U-shaped. After that it is already possible to secure the hoist. For this purpose, numerous experts advise the use of a clamp. Directly the hydraulic mechanism can be defined on the screws. At the same time it must not cover the supports.
Next, to make a car elevator with your own hands, you need to fix the regulator. To do this, a small plate is cut from an iron sheet. It must be welded near the upper beam. The distance from the edge must be at least 2.2 cm. After that the shoe is fixed. The first base is installed at the hydraulic device. At this time, the other 2 supports should be placed at the front edge of the model.
Why you need one
It makes no sense to buy one in most cases. Both in terms of finances and space in the garage. Although, for car owners who have a large garage workshop, its presence is already a huge plus.
First, let’s not complicate life and dig an inspection ditch, which, in principle, except for access to the underbody does not give anything else. However, in the case of any type of elevator we get a certain benefit:
- it’s very convenient to carry out welding and straightening work on the body;
- Maintenance and replacement of the chassis, suspension, brakes, exhaust, and the entire transmission;
- tire fitting and wheel replacement with the help of a hoist is faster and easier;
- preventive maintenance can be combined with minor repairs.
What’s better: to assemble the elevator yourself or buy one
People often assemble the elevator themselves because a new factory design is expensive. It should be taken into account that it is not always an easy task to make a homemade hoist. In addition, if the construction is assembled incorrectly, its use can be dangerous.
The installed vehicle falls from the device if:
- The weight of the car shows the load, which the homemade lifting unit can not hold;
- the fixation mechanism does not work properly;
- the support device does not withstand the load;
- the homemade device has improperly installed supports, or they are poorly secured.
Also difficulties in the creation of the device arise because some elements of the design cannot be performed without special equipment. For example, it is difficult to make large lengths of propellers. Therefore, it is quite difficult to perform this construction by yourself. Many craftsmen instead of this device make a tipper for the car, as it is easier to make.
When creating a device, most of the parts will need to buy in stores, so the final cost of the finished device may be considerable.
In addition, you will need an accurate calculation of all components, which can only be made by an engineer experienced in performing such work. If you do not have such knowledge, you will have to order a project with all the calculations in a special organization, which will require financial costs. If a mistake is made in the calculations, the device will not be able to withstand a large load.
Therefore, if you are not sure that you can implement such a complex project in reality, it is better to create a tipper for the vehicle, which will be safer.
Cars tend to break down, require periodic maintenance, like any technique. Access to the underside in garage conditions is often impossible due to the lack of a hoist. Having all the necessary tools, equipped and ready to work elevator is possible to make replacement of consumables undercarriage, transmission, engine. Despite the fact that the device is in demand when repairing cars with their own hands, it is very expensive to buy it for use in their own needs. Maintenance can be performed no more than twice a year, so it is better to make the units and assemblies with your own hands.
Basic requirements for the manufacture of a scissor lift mechanism
It is important during the manufacture of the lifting mechanism to ensure that the design meets the basic requirements.
If the basic rules are ignored, the device will not work properly and the mechanism can pose a threat to the person who uses it.
First of all, it is important to determine to what height the equipment will be able to lift loads.
There are scissor tables that can lift up to one meter in height, and some devices can lift up to two or three meters in height.
Given this indicator, it is important to comply with certain requirements and safety rules.
Analyzing the future design, it is necessary to correctly, in accordance with the norms:
- Choose an electric or hydraulic drive;
- develop a scheme of the elevator;
- Choose a system of regulation and control of the device;
- Think about fixing the equipment to the floor.
Both self-propelled and stationary hoists are made.
The stationary device is securely fastened to the concrete floor, and self-propelled lift tables can be moved as needed.
Stationary devices are much safer for people and property than mobile devices.
Types of vehicle elevators
There are three types of lifting units for vehicle repair:
According to the method of lifting the machine elevators are divided:
The most common type of car elevator are forked screw devices. Their base is a shaft made of tool steel, withstanding a force of several tons. But to make such a device at home is almost impossible because of the complexity of the design of forks. That’s why for self making it is better to use screw platform devices.
They are made in the form of two channels, placed in parallel to each other, with the ribs facing down, attached to the screw drive devices, providing the lifting of the entire structure. In such units the requirements to the shafts are not too strict, because the lifting is provided by four shafts instead of two. Their significant disadvantage is the need to use a jack to perform suspension repair, since the car wheels are not suspended, but are on the channels.
Often platform and fork elevators for transport are made with a chain drive. In terms of their parameters they are not worse than screw ones, but they are much more complicated in production, synchronous operation of electric drives and brakes is required. To produce scissor-type lifting devices, a hydraulic drive is usually used, but some craftsmen conduct experiments with screw drive and chain drive.
In a sale it is possible to meet some following kinds of elevators:
8 AMAZING ELEVATORS AND LIFTS You Wont Believe Exist
- Standing. of the load is on the vertical column. The lower part is fixed by means of anchor bolts screwed into the concrete floor. There is a lifting mechanism on the side of such a system, most often of the electromechanical or electrohydraulic type. There is also an extra attachment. Depending on the number of uprights can be: single, double and four-post.
- The scissor stay is used for maintenance and adjustments of the vehicle. The main advantage is the floor-level installation. Due to its special design it does not take up much space. Most often the lifting is by means of a hydraulic drive. This guarantees a low noise level, smooth running and a long service life.
- The plunger is suitable for the maintenance of passenger cars and commercial vehicles. Available in several variants, depending on the number of rams. Allows easy work with access to the car from any side.
- The mobile type is chosen by owners of service stations for versatility and easy maintenance. Their installation does not require a specially prepared foundation. Easy to install in any room. The main advantage. mobility.
