Abstract

A vehicle lift has a support platform and a pair of scissor mechanisms underneath it for supporting it, and raising and lowering it. An actuator, for example, an hydraulic cylinder, that is connected between the scissor arms. The ends of one pair of scissor arms include rollers for engaging the ground, the rollers permitting the lift to be raised and lowered. A cart or other lifting device is provided for lifting one end of the lift, to support it on wheels of the cart. With the other end of the lift supported on the rollers of the scissor arms, the lift can be freely moved around on a flat surface. The lift can have a simple ratchet locking mechanism including a cam, which provides a simple mechanism for locking the lift in a raised position, and for enabling it to be lowered.
