Abstract

A modular lift assembly includes a frame, at least one head block connected to the frame, a drum rotatably connected to the frame about an axis of rotation and having at least one winding section, and a drive mechanism operatively connected to the drum for rotating the drum. In various examples, the lift assembly includes at least one loft block internal or external relative to the frame. The loft block is configured to guide a cable from the at least one head block to a load. The lift assembly can further include a load brake positioned along the axis of drum rotation to reduce risks associated with a drive or motor failure.
