Abstract
A hydraulic reel drive wherein the reel motor is driven by a hydraulic pump, which is adjustable in a continuous manner and operates therewith in a closed oil circulating system. The advantage of this arrangement is that the reel always rotates uniformly independently of the instantaneous load thereon. Another advantage thereof is that by using a hydraulic pump, which is adjustable in a continuous manner, only that amount of oil is ever circulated as is required to drive the reel at a predetermined rotational speed.
