The present disclosure describes a winch comprising a recoiling mechanism engaged to a winding member having a strap installed on, and wound around, the winding member. By rotating the strap away from the winding member to secure an object to the winch, a coil, which is positioned within the recoiling mechanism, is rotated from an unbiased position at rest to a biased position not at rest. Once the strap is disconnected and a locking gear is disengaged, the coil is naturally rotated back to its original unbiased position at rest, which in turn rotates the winding member and rewinds the strap around it.

A winch includes a coupling A, a coupling B, a rectangular spring, a gear wheel, a gear rack, a friction ring, and a transmission shaft, etc. By increasing the distance between the adjacent internal teeth of the two-stage planet carrier, it ensures that the three-stage sun gear can be smoothly inserted into the two-stage planet carrier even if the elasticity of spring A is reduced, such that the engagement width between the three-stage sun gear and the two-stage planet carrier can reach the normal requirements. With the design of sliding gear ring and spring C, it can greatly reduce the phenomenon of mis-engagement when the external teeth of the three-stage sun gear enter the internal teeth spacing of the two-stage planet carrier, protect the teeth integrity of the three-stage sun gear and the two-stage planet carrier.

A winch control system is disclosed. The winch control system may be used to control or operate a winch on a vehicle in a selected mode, such as a plow mode. The winch control system may include or receive input from selected sensors relative to the vehicle to assist in control and operation of the winch.

A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

A removable winch handle assembly for engaging a winch gear within a gearbox comprises: a handle receiver having at least a portion thereof exposed outside the gearbox, a seal between the handle receiver and the gear box, an engagement mechanism in the gearbox, the engagement mechanism coupled to the handle receiver to rotate with the handle receiver, wherein rotation of the engagement mechanism engages the winch gear, and a winch handle selectively coupled to the handle receiver, wherein, rotation of the winch handle causes rotation of the handle receiver when attached, the winch handle detachable from the handle receiver, wherein the gearbox opening is sealed by the seal when the winch handle is detached from the handle receiver.

A winch assembly including a mount attachable to a vehicle, and a guide attached to the mount; including a winch having a drum for winding and unwinding a line, and a motor for driving the drum about a winding axis, wherein the drum has a helical groove for receiving the line as it is wound. A frame connects to the first and second end of the drum and is adapted to move relative to the guide so as to synchronize movement of the drum along the winding axis so that the line is aligned with the helical groove during winding and unwinding. A rod is attached to the frame and generally parallel to the winding axis, and passes through a hole in the guide, allowing the movement of the drum along the winding axis but preventing the frame from rotating about the winding axis is disclosed.

A cable guide device, including a cable with one end attached to an unwinding/rewinding device, another end having structure for accepting applied force, with cable therebetween guided by a cable guide, wherein as force is applied to the cable, the cable guide causes redirection of the applied force eliminating cable binding as cable is rewound. One embodiment is a trunnion-sheave winch-apparatus for object recovery, including: a trunnion-sheave of a pair of sheaves with cable inserted therebetween, one cable end attached to a winch drum with a hook attached to its other end for connection to an object being recovered, wherein as the object is recovered the force applied to the cable is redirected by the trunnion-sheave causing said cable to be maintained at a minimum of 90 contact with the pair of sheaves regardless of the angle of force being applied to the cable causing elimination of cable binding.
