Working principle and purchase tips of car lifts

Car lifts are car maintenance machines used in the car repair industry. The nature and quality of their products directly affect the personal safety of maintenance personnel. Lifts play a vital role in car repair and maintenance. Whether it is a major overhaul of the whole vehicle or a minor repair and maintenance, it is indispensable. In maintenance and repair enterprises of various sizes, whether it is a comprehensive repair shop that repairs a variety of models, or a street shop with a single business scope (such as a tire shop), almost all of them need to be equipped with lifts.

Since the 1990s, lifts have gradually become popular. With the increase in the number of cars, the demand for lifts as an important tool for car repair has also greatly increased. Now the lift market has nearly 100 Chinese and foreign brands, and hundreds of product series. The advantages and characteristics of various lifts are also different.

According to the function and shape, lifts can generally be divided into three categories: two-column, four-column, and scissor-type.

2 Post Car Lift

The two-post car lift is a special mechanical lifting equipment commonly used by car repair and maintenance units, and is widely used in the repair and maintenance of small cars such as sedans. The two-post car lift can lift the car in the air while saving a lot of ground space, making it convenient for ground operations.

The main feature of the four-post lift is that the limit switch will automatically cut off the power and the hydraulic circuit in the hydraulic pump when the lift rises to the maximum lifting height.

Scissor Car Lift

The scissor lift is equipped with a small scissor, which uses the same hydraulic balance control method as the main scissor, and the maximum lifting height is increased by 400mm. High-precision four-wheel alignment can be configured. The hydraulic method of the main and auxiliary oil cylinders ensures the balance of the system, with the following advantages: no connecting rod, comforta

ble work, no obstacles, and the distance between the running boards can be adjusted at will.
