Car Lift

Car Lift

A car lift, also called a car lift, is a forklift that specializes in the vertical movement of vehicles. They are used to transport these vehicles from one height to another with or without an occupant. For this purpose, its design is generally robust and simple, so that it can withstand the blows well and facilitate the entry and exit of vehicles. Its technology can be more or less elaborated in its presentation and in the handling devices, but in general it uses the same basic physical principles.

How do they work?

The most efficient and most widespread car lifts are the hydraulic ones that work by the Pascal principle. This one that affirms that, when exerting pressure on a liquid body, it is transmitted to the entire container of the liquid without diminishing its volume. In a container that has non-deformable retaining walls, these will direct all this pressure towards the only point that is free to release it.

In the case of a hydraulic lift, an actuator piston is available, that is, the place where the inlet pressure is exerted, which is of a smaller size compared to the executing piston. The pressure is lower at the point of action, although the distance traveled during it increases with respect to that obtained in the executing piston. In this way, a high pressure can be generated to lift a very heavy element by exerting a small pressure for a long stroke.
