Methods and systems are provided for a winch including a rotatable tie structure. In one example, a winch may include a tie structure coupled to a top side of a winch. Notches formed in main cross rails of the tie structure enable rotation of the tie structure relative to a housing of the winch.

A load sensing device for a rescue hoist includes a load pin mounted coaxially with a traction sheave. A cable extends from a cable drum and over the traction sheave before exiting the rescue hoist. The traction sheave is rotatably driven about a traction sheave axis to maintain a back tension on the portion of the cable extending between the cable drum and the traction sheave. When the cable is loaded, strain gauges in the load pin sense a strain on the load pin caused by the load, and the strain information is communicated to a load calculator. Entry angle information is also determined and communicated to the load calculator. The load calculator determines the load on the cable based on the strain information and the entry angle information.

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.

The present disclosure discloses an automatic clutch winch comprising a motor, a gear reduction unit actuated by the motor, and a winding drum drivably coupled with the gear reduction unit. The gear reduction unit comprises a planetary gear assembly drivably coupled with the winding drum, a movable ring gear engaging with the planetary gear assembly, a DC gear motor, a cam driven by the DC gear motor to rotate, and a pull rod driven by the cam. The pull rod is driven by the cam on a first end to enter or exit a notch of a plurality of notches in the movable ring gear. The disclosed automatic clutch winch can provide protection for the internal components during an emergent situation.

A hunted game winching assembly for drawing hunted game through uneven area includes a winch has a cable is wrapped therearound when the winch is turned on to rotate in a first direction. The cable is drawn off of the winch when the winch is urged to rotate in a second direction. A harness is releasably coupled to the cable and the harness is positionable around hunted game. In this way the winch can draw the hunted game toward the winch when the winch is turned on the rotate in the first direction. A pair of handles is each of the handles is coupled to and extends in opposite directions from the winch. Each of the handles can be gripped to positioned the winch between a user and the hunted game.

The present disclosure provides an appliance for towing compact loads (e.g., logs), and include an auxiliary winch provided in combination with a main winch on a tractor without the need for separate powering means or the need to transport said auxiliary winch to the area adjacent to the load (away from the main winch/tractor.) The appliance may be provided by upgrading an existing tractor winch by, for example, attaching the auxiliary winch to a casing of the main winch, or to the ground adjacent the tractor with the main winch. The auxiliary winch may be furnished with a driving means powered by disposable powering means on the tractor that may include auxiliary pulley block(s) with an accompanying accessory to provide attachment thereof to the terrain, with each pulley block suitable for guiding an auxiliary cable in the area outside of the line between the main winch and the load.
