Abstract
A jack includes a base having a pair of spaced apart side members with a substantially horizontally oriented platform overlying a forward portion of the base. A pair of support arms pivotably connect the platform to the side members, and a lift arm is pivotably connected between the platform and the side members. A driver assembly mounted to a rear portion of the base in response to manual actuation moves the platform between a lowered and a plurality elevated positions while maintaining the horizontal orientation of the platform.
