ABSTRACT:
An apparatus guides a cable so that the cable is wound on a drum in a substantially uniform manner. The apparatus includes a rigid elongated support slidable within bearings mounted to a floor. The elongated support is positioned substantially parallel to the axis of the drum. A guide support member is fixedly attached at one end to the elongated 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 having a hydraulic actuator that moves the guide support. 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 actuator. The actuator moves the guide support such that the cable is wound on the drum in a substantially even manner.
