ABSTRACT:
An apparatus guides a cable so that the cable is wound on a drum in a substantially uniform manner. The apparatus includes a support slidable attached to a longitudinal stationary guide tube mounted to a floor. The tube is positioned substantially parallel to the axis of the drum. A guide support member is slidably attached at one end to the support and has a longitudinal axis disposed substantially perpendicular to the axis of the drum. A first guide is positioned proximate a first end of the guide support and a second guide is positioned proximate a second end of the guide support. The first and second guides guide the cable along the longitudinal axis of the guide support. Power to move the guide support is provided by a hydraulic system to a hydraulic actuator that moves the guide support. The hydraulic actuator includes a hydraulic motor mounted on the guide support member and a sprocket drivably attached to the motor. The sprocket engages a stationary double link chain that extends parallel to the axis of the drum. A cable contact-valve actuating member is positioned on the guide support between the first guide and second guide contacting the cable on two sides. The actuating member is engaged by the cable as the cable is being wound on the drum, activating a valve which directs hydraulic fluid into the motor. The motor, in cooperation with the chain, moves the guide support such that the cable it wound on the drum in a substantially even manner.
