    摘要： A remote controlled lift assembly includes a pair of supports is each mountable to a respective outrigger of scaffolding. A winch unit is positionable on the supports when the supports are mounted on the scaffolding and the winch unit has a cable extending downwardly therefrom. The cable is lowered or lifted when the winch is actuated. A receiver is coupled to the winch unit and the receiver is in electrical communication with the winch unit. A remote control is provided that is carried by a user and the remote control is in wireless electrical communication with the receiver. In this way the user can remotely lift and lower the cable for lifting and lowering cargo.

    摘要： A safety control mechanism for a load line forming part of an extensible boom crane which has a plurality of sections moved relative to each other by power means. The cable supports a load supporting member on one of the crane sections and is reeled or unreeled from a driven drum supported adjacent another of the sections. The safety control means incorporates mechanism which will render the power means inoperative when the tension on the cable reaches a certain level. The safety control means consists of a bracket pivotally supporting the drum and pivoted about an axis. The bracket is normally biased to a first position, with the biasing means accommodating movement from the first position after the tensile load exceeds a lower level to actuate control means, forming part of the power means, to render the power means inoperative when the tensile load on the cable exceeds a desired maximum level.

    摘要： A lower mast is attached to a base having fork pockets, and is pivotal between vertical and horizontal positions. A lower mast brace assembly has a receiver configured to receive the lower mast as it is moved into the generally vertical position, and to retain it there. An upper mast having a hoist at its upper end slides into the lower mast. The upper mast has a dogleg that offsets the hoist forward of the centerline of the lower mast. A hook is attached to the lower mast brace assembly near the receiver. The hinge, the lower mast brace assembly, the dogleg of the upper mast, and the hook are arranged so that the hoist may be used to pull the mast from the horizontal position to the vertical position. A combination limit switch, buffer, and vertical shutoff switch may be attached to the upper end of the upper mast.
