Abstract
Abstract A stationary or mobile cable spooling system for winding up electrical cables used on drilling rigs comprised of an axle for insertion into a cable spool, a yoke for rotationally mounting the axle, a hydraulic motor coupled to the axle for rotating the spool and a cable guide system which evenly winds the cable onto the spool. The cable guide system is comprised of a cable guide mounted on a diamond grooved shaft which traverses from one side of the shaft to the other guiding the cable onto the spool. The hydraulic motor is driven by a pressure compensated hydraulic pump which prevents excessive force being applied to the cable as it is being wound on a spool. If the cable should catch or bind in any fashion and the stress on the cable exceeds a certain amount, the hydraulic motor will slowly stop when the pressure in the hydraulic pump exceeds a pre-determined amount. The transportable spooling system is comprised of a tiltable frame having the spooling system mounted on a trailer for transporting the system by towing it from one site to another. The tilt frame is tilted up and locked for transportation and is tilted down to provide a stationary platform for use at a site.
