ABSTRACT:
A portable lift for transporting cargo between different vertical levels of a building. The lift comprises a frame mounted for movement on a plurality of wheels. A carriage having a cantilevered platform that is adapted to support the cargo is mounted for vertical movement on the frame between a lower level and an upper level. The wheels can be manually moved between a lower supporting position where they support the frame for movement to an upper, non-supporting position. Movement of the wheels to the upper, non-supporting position automatically engages a locking mechanism to lock the frame to the building to prevent accidental movement of the frame during a loading operation. The platform of the carriage can be selectively positioned at either a lower position to receive cargo from mechanical handling equipment, or at an upper position to receive a manually carried cargo.
