[0002] A two-post lift is a special mechanical lifting device commonly used by automobile repair and maintenance units. It usually has two vertical columns with two telescopic arms on each column. When the vehicle needs to be lifted for underbody inspection, replacement of parts or other maintenance work, the telescopic arms are extended to the underside of the chassis. There is usually a rubber tray at the end of the telescopic arms, which contacts the chassis of the vehicle to lift the vehicle, making it easier for maintenance personnel to perform maintenance on the vehicle.
