ABSTRACT:
An improved cable paying out and taking up device particularly for use in underground or overhead cable pulling environments which includes a novel winch assembly disposed on a vehicle, a swivel fairlead disposed on a trailing portion of the vehicle bed adapted for facile removal and redeployment, the swivel fairlead provided with instrumentalities for operatively orienting a pulley sheave associated with the fairlead in 360.degree. of direction and allowing disassociation of the pulley sheave from its associated support drum so that cable including an enlarged end unable to fit within clearances about the pulley sheave can be threaded through the swivel fairlead without disassociation of the cable from the enlarged end. The novel winch briefly includes a pair of winches modified to accommodate a removable bull wheel having a plurality of grooves on its outer face, the grooves dimensioned to receive cables corresponding to the diameter of the cable, an instrumentality for assuring level winding, a pressure responsive instrumentality associated with a reel to accommodate variations in effective reel diameter due to cable build-up and pay-out, so that hydraulic pressure and synchronization of the various rotating winches and reel can be coordinated for the accurate functioning of the apparatus.
