摘要:
A wheelchair lift with hydraulic power unit and automated folding platform for installation on the floor, inside the opening defining walls of a vehicle to provide for loading and unloading of wheelchair occupants to and from the vehicle. Completely automated, retractable, collapsable folding platform. Hydraulic power unit (10) of the lift and the hydraulic cylinder (28) are totally enclosed, and contained in the power box. The power unit provides power for upward motion of the platform and gravity descent for downward motion of the platform. The platform is pivotally retracted and held in a vertical position in half of the opening space of the vehicle door. The folding motion is accomplished by a folding arm driven against a cam roller which starts the motion of the ball joint linkages inside the platform tubing structure. This initiates a resulting revolving motion of one half section of the platform which folds the platform in a smooth un-interrupted continuous manner.
