摘要： This invention relates to a cable drive unit (1) for use with a free stall cleaning system (101). The cable drive unit (1) includes a base frame (3), a support frame (5) being displaceable with respect to the base frame (3) via a corresponding displacement assembly (7), and a drum (9) pivotably mountable about the support frame (5) and displaceable therewith for receiving a cable (11) to be wound about said drum (9). Also described is a kit for assembling a cable drive unit (1) and a free stall cleaning system (101). The invention further includes a method of winding a cable (11) of a free stall cleaning system (101) about a drum (9) via the present cable drive unit (1).

摘要： A hoist system having a drum primarily self-contained within a batten, for raising and lowering lighting, sound equipment, curtains and the like in a performance environment. The hoist system may be adapted with safety mechanisms including an overload sensor and/or a slack line detector. The system may be provided in the form of a point hoist. The compact system is highly scalable to a variety of spaces and applications, including school and public theaters and concert halls, as well as some homes, private business, etc. Additional features include various cable management systems and trim adjustment mechanisms for use with the hoist system.

摘要： A hoist includes a cable deployment sensor to sense the length of a cable that is deployed from a cable drum of the hoist. The cable deployment sensor includes a stationary ring and a rotatable ring disposed coaxially on the cable drum axis. A cluster assembly is mounted to rotate about the cable drum axis simultaneously with the cable drum. The cluster assembly includes a cluster gear with a first gear engaging the stationary ring and a second gear engaging the rotatable ring. The second gear drives the rotatable ring about the cable drum axis, and the rotatable ring drives rotation of an input gear for a sensor assembly.

摘要： A hoist system having a drum primarily self-contained within a batten, for raising and lowering lighting, sound equipment, curtains and the like, often in a performance environment. The compact system is highly scalable to a variety of spaces and applications, including school and public theaters and concert halls, as well as some homes, private business, etc. The hoist system may be adapted with safety mechanisms including an overspeed detector, which may comprise a centrifugal detection mechanism coupled to an elongate member of the system; dampening means; a compact mechanism for trimming or adjusting an operative length of elongate member; stabilizing pipe shaft bearings; elongate member diverter pulley mechanisms load balancing termination points. Additional features include various alternative combination hoist implementations and orientations, and alternative incorporated attachment mechanisms for use with the hoist system.

摘要： A lift assembly comprises a base, a drive mechanism, a flexible drive element extending from the drive mechanism along a fleet axis, and a sheave directing the drive element from the fleet axis to an output axis. The sheave is coupled to the base at a first sheave mount aligned with the fleet axis. The assembly can further include a second sheave mount aligned with the fleet axis and configured to be coupled to the sheave to allow the sheave to be de-coupled from the first sheave mount and coupled to the second sheave mount, resulting in substantially no change in a fleet angle of the fleet axis. Preferably, the sheave is positioned on a first side of the fleet axis when coupled to the first sheave mount, and the sheave is positioned on a second side of the fleet axis (e.g., opposite the first side) when coupled to the second sheave mount.

摘要： A winch for winding and unwinding of a tension line, with a winding drum that is rotational around its central axis so that the tension line is windable and unwindable in windings running around the winding drum, and with a rotating actuator for driving a rotation of the winding drum, wherein the winding drum is arranged in a longitudinally movable manner along its central axis with respect to a base of the winch. It is a threaded rod extending in the central axis and having an external thread, wherein the winding drum is arranged rotationally around the threaded rod by means of a counter-thread that engages in the external thread.

摘要： A lift assembly including a base, a drive mechanism, and a drum assembly adapted to be driven by the drive mechanism. The drum assembly includes first and second drum segments positioned adjacent each other, each drum segment including a small diameter portion, a large diameter portion, and a tapered portion between the small diameter portion and the large diameter portion. The lift assembly further includes first and second flexible drive elements at least partially wrapped around the small diameter portions of the first and second drum segments, respectively.

摘要： A lift assembly having a drum rotatably mounted to a frame and linearly translatable with respect to the frame. A plurality of head blocks are connected to the frame along a helical mounting path, wherein linear translation of the drum during takeoff or take-up maintains a predetermined fleet angle between a take off point from the drum and the head block.
