Description

Technical Field

[0001] The utility model relates to the technical field of automobile repair equipment, in particular to a chassis lift. Background Art

[0002] A car lift is a piece of automotive maintenance equipment used in the auto repair industry to lift vehicles. Its purpose is to elevate the vehicle from the ground to a certain height, making it easier for repair personnel to inspect and repair the vehicle. Lifts play a vital role in auto repair and maintenance, and their quality directly impacts the safety of repair personnel. Almost all vehicle repair shops of all sizes are equipped with lifts, which can be categorized by function and shape into single-post, double-post, four-post, and scissor-type types.

[0003] The four-post lift is currently the most widely used and most stable type. However, since its power mostly comes from hydraulic pumps and hydraulic controllers, the lifting distance requires hydraulic control, the movement accuracy is poor, and the size of the lifting support frame is fixed, while the size of the car chassis is different, making it impossible to adapt to lifting different chassis, which greatly limits the application function of the lift.
