ABSTRACT:
A grocery lift for lifting and lowering grocery loads. The apparatus includes a pair of spaced apart elongate guide rails with a support chassis interposed between the guide rails. The support chassis is mounted to each of the guide rails to permit riding of the support chassis along the guide rails between the top and bottom ends of the guide rails. An upper pulley is provided and is adapted for mounting to the support structure between the guide rails. A winch is provided adjacent the bottom ends of the guide rails. A flexible elongate member is looped around the upper pulley with one end of the flexible elongate member coupled to the support chassis and another end of the flexible elongate member coupled to the winch to permit winding and unwinding of the flexible elongate member about the winch. A support platform is pivotally coupled to the front surface of the support chassis.
