A compensating winch (10, 100, 200) which incorporates elastomeric elements (20, 118, 202, 204) which are deformable in torsional shear about the rotational axis of the drum of the winch to absorb shock loading of the cable (22) to increase the service life of the cable and winch and resist catastrophic failure. The elastomeric element can comprise a series of alternating elastomeric rings (48, 121) and rigid rings (50, 119) bonded together to form a unitary structure. Concentric elastomeric elements (202, 204) can be connected in a series relationship to provide for greater annular deflection of a drum versus a drive element. |
