Abstract: A compression chuck for variously conducting and braking a rope, wherein the compression chuck includes a first and second portions. The invention includes a first biasing mechanism which maintains the compression chuck first and second portions in a disengaged condition with the rope, wherein the rope is conducted freely in response to outside forces on the rope.

Abstract: The present invention relates to an improved level wind arm for a winch drum assembly, and a winch drum assembly incorporating such a level wind arm. The level wind arm includes a cross member adapted to bias against an outwardly extending portion of rope, the cross member being concave so that more force is required for the rope spindle associated with the cross member to “climb” the slope of the cross member, causing a momentary pause in motion of the spindle after it reaches the end of wind stroke. This momentary pause allows for rope being wound onto the drum to rise up the end wall of the drum to create a new layer which is aligned and consistent with the layer below, without causing gaps in the rope or other circumstances which could lead to the rope accumulating at any one point, or becoming tangled. The present invention also includes means of ensuring that tension is maintained in the rope, and that the rope does not jump off the reel and, for example, into the clutch mechanism.

Abstract: Controlling the orientation of a load suspended from a bearing wire employs one master winch, one slave winch and a winch control. Each of the winches has a motor and a bi-directional rotational spool with a tagline. The winches are on the ground, the crane or the load. Each tagline is attached to the load for applying a controlled torque to the load about the bearing wire. The control system comprises tagline tension sensors and spool rotation sensors. The control system is connected to each winch motor for simultaneously rotating the winch spools, until preset tagline tensions are sensed during horizontal and/or vertical movement of the load. If necessary, the spools are rotated with rotation speeds for maintaining a desired orientation of the load, based on the determined tagline tensions. After relieving tagline tensions, the taglines are disconnected from the load.
