Lifts for cars: technical specifications

For qualitative diagnostics of the car, its inspection, as well as repair work and maintenance in each station, lifts for machines are installed. They help in carrying out locksmith work, body repair, maintenance of the running gear, in adjusting the camber-toe. Without lifts, it is difficult to manage even on bus services. Also these units are used for engine repairs, maintenance of the electric part of the car. Not all types of work can easily be done with the help of a viewing pit. Today, there are a large number of types of lifts for machines, which are used for different types of work. Consider the most basic types, as well as the main characteristics of this equipment.

Characteristics of car lifts

So, among the important characteristics can be distinguished load capacity, speed, as well as the height of the lift, clearance, type of construction.

Characteristics of the carrying capacity are determined by the weight of the car, which specific equipment is able to raise safely. For repair and maintenance of cars and small trucks, the permissible mass is from one and a half to five tons.

As for the lifting speed, this parameter differs only slightly for most units. On average, the speed is from one to two minutes. Electromechanical equipment has a high speed of lifting the machine. Height is often on many types of lifts - no higher than two meters. As for the overall height, this parameter does not exceed four meters. Practice shows that for any repair work there is no need to raise the car very high. Sometimes in the process of servicing machines with a high roof there is a need for a height of 4000 to 4200 mm. Also, for the height of the lift, it is possible to distinguish units for tire shops that are capable of lifting the machine to a small height.

The clearance of the lifts for the machines is the minimum height when the feet are lowered. This parameter for many types of equipment will be in the range from 95 to 110 millimeters. However, there are low-profile mechanisms. Here the clearance is 75 to 90 millimeters. Such systems are relevant for cars with low clearance or body kit.

Security Requirements

Safety requirements for the operation of such equipment are also important. This is mainly aimed at eliminating the risks of falling the elevator and on electrical safety. Especially high demands are made on mobile equipment, as well as on units operating in the open air. An example is a car with a lift.

Types of structures

Each of them differs according to the principle of the lifting mechanism. Also the type determines how the car will be attached to the lifting mechanism. By the type of drive all equipment can be divided into:

• Electromechanical.
• Hydraulic.
• Electrohydraulic.
• Pneumohydraulic.
• Pneumatic.

By the way the support elements are made, it is possible to distinguish rack, plunger lifts, as well as scissor units.

Each specific type of equipment has its own design features. As for the field of application, it can be different. The scope of use in most is determined by the type of service performed, as well as by what machines are serviced at the station. Now electro-hydraulic units are especially popular on many SRTs. They have a lot of serious advantages over electromechanical systems. So, in the design there are no mechanical parts and components that are subject to great wear and tear. Significantly higher overall reliability and high resource. The unit is characterized by a more smooth running, less electricity consumption, simple maintenance, the possibility of easy lowering of the car.

These lifts for machines are equipped with additional supports, which greatly increase the safety of operation.

Rack lift

Here the main load is on the vertical rack. The lower part, which provides stability to the system, is usually mounted by means of anchor bolts in the concrete floor base. On the side of this structure there is a lifting mechanism - it can be electromechanical or electrohydraulic type. Also on the side you can see the mounts. Rack aggregates can also be performed in a mobile mobile version.

According to the number of racks, these units are divided into single-column structures, two- and four-post. Let's consider features of each of them.

Single column equipment

This is the most universal and, in addition, mobile lifting equipment. They are used mainly in small service stations or garage type services. There are stationary as well as mobile models. With regard to stationary equipment, the carrying capacity of such equipment is 2000 kg. Characteristics of carrying capacity of mobile models - no more than 250 kg. At the same time, no more than four mobile lifts for cars can be used.

With the help of this equipment, the machine rises behind the wheels or over the thresholds. The car rises with one, or at once from two sides. It depends on the number of such equipment in stock. Often single-column lift units can be found in car washes and service stations, where anti-corrosion treatment of the bottom is provided. Often, the models are found in tire shops.

Two-post lift

This is one of the most common types of equipment. These structures are ideal for repair, diagnostics and maintenance. The unit does not have a platform, which makes it possible to leave the chassis suspended. According to the type of drive, equipment of electromechanical or electrohydraulic type is distinguished. The first are easier to operate, and the latter are more safe, reliable, durable and differ in the maximum speed of lowering the machine. Characteristics of lifting capacity allow lifting the machine on a lift with a weight of up to 8 tons. More often, 5-ton models are installed on the service station.

By type of weighting, symmetrical and asymmetrical systems can be distinguished. By the method of synchronization, equipment with a lower or upper type is selected.

Four-column auto lift

These systems are characterized by a large load-carrying capacity. They are widely used in freight service stations. Between each other in this group, the models are distinguished by the carrying capacity and the length of the platform. With dimensions up to 5000 mm, the unit is suitable for passenger cars. Among the advantages is the possibility of repairing long-boring machines, low price, simplicity and reliability, the possibility of using a lift for trucks. Among the minuses - the size, uncomfortable jumper.

Scissor lifts

These systems are designed for maintenance or for adjustments. Among the advantages can be identified the possibility of installing flush with the floor surface. Due to the design features that allow the system to be folded, the unit is quite compact.

In most cases, lifting the machine on a lift of this type is carried out on the basis of a hydraulic drive. Due to this, silent operation is achieved, smooth running, high durability. Allocate stationary or mobile models. Portable versions are used for quick maintenance outside the workshop. As for the basic characteristics, the load capacity is only up to 5 tons. The main disadvantage of these designs is a high price.

Plunger equipment

These units are widely used in works related to the maintenance and repair of trucks and cars. There are lifts with one, two and four plungers. There are platform models or equipped with paws. Also, there are models of floor mounting. But the most common systems are built in a special groove in the floor. These are popular hydraulic lifts for the machine.

The bearing part is located on the upper end parts of the plungers. This scheme allows you to provide the ability to conduct work and at the same time without obstacles to approach the car from any side. Among the advantages of this technology can be distinguished high level of reliability, comfort in operation, smoothness of ups and downs, noiselessness, a wide range of models. These units are easily combined with the stands for the adjustment of camber. Among the shortcomings can be identified only a high price, as well as complexity in the installation process.

Mobile column hoist

These solutions are considered one of the most versatile and economical when servicing heavy trucks. They do not have strict requirements in terms of foundation preparation. You can install them in any room. Mobility allows you to save space in the room. Due to the electronic unit, synchronization is carried out. Carrying capacity can reach from 12 to 80 tons.

Special lifts for cars

In this group there are solutions for tire service, for body repair, and also for maintenance of motorcycles.

The unit for tire fitting is a specialized platform equipment, which greatly facilitates the task of replacing the wheels. The models are distinguished by the drive. It can be pneumatic, electrohydraulic, electromechanical. The construction is scissor type. Along with these devices in the tire shops also use lifts for the car.

Equipment for body repairs can significantly improve the performance of the work performed. Models are completely synchronized. The actuator can be pneumohydraulic or pneumatic.

Homemade lift

On large and medium-sized SRT lifts - not uncommon. But still there were masters who work in garages, and a small business does not allow to purchase serious equipment. In this case, you can make a lift for the machine with your own hands. It will be no worse than the firm's designs for efficiency and reliability. But for the manufacture of such a system you need to have the skills to work with metal, to be able to use a welding machine.

Assembling a self-made lift is very hard work, requiring the creation of drawings and production schemes with a different type of drive. As a compromise solution, you can consider buying already used equipment. The cost of such lifts is an order of magnitude lower, while you significantly save time for their installation.
