ABSTRACT:
An apparatus for unwinding underground cables includes a framework chassis which is open ended and open bottomed and rests on the ground such as a trench bottom. Mounted on the chassis are horizontal support rollers which support the horizontal cable as it is propelled through the chassis by a peripherally grooved driven pulley applied against the upper side of the cable. The pulley is driven about a horizontal axis by an electric motor via a gearbox. The chassis carries vertical guide rollers on either side of the cable to constrain it to a given path. The guide rollers on one side are movable to permit release of the cable from that path when a support arm carrying the pulley, gearbox and motor is pivoted upwardly, by manual action on a pivotable handle, to lift the pulley off the cable.
