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 velocity control device for controlling the velocity of a load on a flexible tension member. The device can include a chassis having a chassis peripheral surface, with a portion of the chassis peripheral surface defining an exit aperture. The device can also include a capstan, the capstan having a proximal face joined to the chassis and a distal face separated at a distance from the proximal face. A peripheral capstan surface can be tapered from a greatest diameter near the distal face to a smallest diameter near the proximal face. The device can include a throttle, the throttle being attached to the chassis. The throttle can an interior surface defining an opening through which the tension member can pass with the interior surface being in at least partial contact with the tension member. Heat produced by kinetic energy in the flexible tension member is transferred to the throttle, and the change in system internal energy produces work in the form of a drag force on the flexible tension member.

摘要： Improvements to a pulley is disclosed. The rope is threaded through the self-locking pulley in the desired direction. At some places, the threading passes the rope or strap in opposing directions to cause a binding and prevent free movement of the rope or strap in one direction. There are no one-way clutches or self-locking teeth to lock movement in a particular direction. A first part it secured to a spinning mount or ceiling so a user can walk around a suspended self-locking pulley and pull the rope or strap from any direction. The second part can pivot and move up-and-down on the first piece. A threaded member alters a frictional lock between the at least two interconnecting pieces. The interaction of the at least two pieces allows for lifting, locking and lowering of a load on the rope or strap.

摘要： A user-controllable braking system, including a descent tether connectable to a support and configurable for descending a user; a rigid body configured to be connectable between the descent tether and a user for enabling control of the descent by the user; a pulley rotatably positioned on the rigid body, the descent tether positionable around the pulley; a brake member yieldably positioned on the rigid body adjacent the pulley; a bias member operatively associated with the brake member to bias the brake member away from the pulley; and a lever pivotally connected to the rigid body and operable to bear against the brake member to controllably overcome the bias member and controllably bear the brake member against a portion of the descent tether. Operation of the lever by the user enables the user to controllably bear the brake member against the portion of the descent tether positioned around the pulley to provide a braking force.

摘要： A line puller designed to accept a Working line (15) through a Working Line Fairlead (14), directing the line around a Capstan (21), and through a brake (28). This line puller is mainly driven by gears or friction rotational devices (38), driving the internal face or cogs (36) of a Capstan. The design allows users to load a Working Line (15) from midsection not requiring the end of the line to load the puller. The puller can be hard mounted or Soft mounted using an Anchor Line (44) fed through incorporated Anchor Fairleads (20). Multiple gear rations allow users to pull objects at different rates.

摘要： A rope grip having a receiving member with a pair of substantially parallel side walls spaced apart a distance sufficient to receive a rope therebetween. The side walls are joined along one side edge thereof so as to define a first engagement. An engagement member slidably received within the side walls and having a second engagement surface and being in a facial spaced relationship with regard to the first engagement surface. A movement restricting member, is positioned to define and restrict the movement of the engagement member within the pair of side walls. An actuating arm having a first end and a second end is secured to the engagement member in such a manner to allow for pivotal movement of the actuating arm, whereby the first end moves in response to a force exerted upon the second end and the first end makes contact with the receiving member causing the engagement member to move within the pair of side walls, such movement of the engagement member causes the second engagement surface to either move closer to or further away from the first engagement surface and accordingly secure or release the rope grip from the rope. A pair of planar members are secured to and depend away from the second engagement surface. The planar members are angularly positioned with respect to the second engagement surface and allow the rope to be angularly displaced with respect to the rope grip. Such placement of the planar members prevents the rope grip from damaging the rope when the rope grip is secured to the rope.
