A snatch ring for off-road vehicle recovery has an annular core and an outer sheave. The outer sheave has an outer winch line groove and the annular core and the outer sheave are concentric. The annular core is rotatably engaged to the outer sheave so that the annular core and the outer sheave can rotate with respect to each other about an axis of rotation. The annular core has an anchor loop passage therethrough.

A containment device, including a housing, a first axle rotatably connected to the housing, the first axle including at least one gear having a plurality of teeth, a second axle rotatably connected to the housing, the second axle including at least one pawl operatively arranged to engage the plurality of teeth, and a line connected to the first axle and engaged with the second axle.

A winch assembly is described and shown herein. The winch assembly may include a first housing member having a first retaining member formed therein and a second housing member having a second retaining member formed therein, the second housing member secured to the first housing member forming a winch housing. The winch assembly may further include a drive system generally positioned within the winch housing, and a winch drum operatively coupled with the drive system and rotationally secured with the first and second retaining members.

A system is provided to compensate for heave of a vessel in which the compensation system has a first panel with a first magnetic field having magnetic flux disposed in a first direction and a second panel parallel to the first panel. The second panel has a second magnetic field having magnetic flux disposed in a second direction with the first magnetic field parallel to the second magnetic field. A conducting loop is located between the first panel and the second panel. The conducting loop is attachable to a cable connected to a load suspended in water. Compensating force generated by the first magnetic field and the second magnetic field transfers to the cable to compensate for heaving motion of the vessel and stabilize the cable-connected load in the water.

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.

Methods, apparatus, and systems are provided for rigging interfaces couple to winch cable terminals that protect outer surfaces of fairleads and rigging devices as connections between objects. In one example, a rigging interface may include curved surfaces adapted to nest against a fairlead. In another example, a rigging device may have one or more removable elements allowing for coupling of the device to other objects.
