ABSTRACT:
A wheelchair lift assembly is provided. The wheelchair lift assembly includes a frame, a platform, and a lift mechanism associated with the frame. The lift mechanism includes a stabilizing arm and at least one lift arm member having a first end connected to the platform. The first end of the lift arm member pivots and translates relative to the platform as the platform is reciprocated between raised and lowered positions. The wheelchair lift assembly also includes a drive assembly. The drive assembly selectively provides a driving force to the lift mechanism without directly providing the driving force to the stabilizing arm.
