ABSTRACT:
A small vehicle lift of the parallelogram type is described wherein parallel pivoting legs are pivotally attached at their opposing ends to a base and a support platform, whereby the lift ranges from a lowered state wherein the support platform is in close parallel relation to the base and a raised position wherein the support platform is in spaced parallel relation to the base. Both the support platform and the base pivotally bear the legs within channels and thereby surround the legs at opposing planes adjacent the planes wherein the legs pivot. The channels within the base also have wheels rotatably mounted therein to allow the lift to be easily transported. Two opposing pivoting legs are affixed together by a bridge member which is pivotally connected to a linear actuator, which is in turn pivotally connected to the base. Actuation of the linear actuator thereby raises and lowers the support platform with respect to the base. The bridge member is situated nearer the upper leg ends than the lower leg ends to provide greater mechanical advantage.
