ABSTRACT:
A hydraulically powered, direct drive, quick response, bidirectional rotation, and variable speed and torque wireline multiple reel assembly for winding or unwinding cable under the control of an operator. A frame for rotatably supporting one or more reels. Two hydraulic wheel hubs of different cubic inch displacement are coaxially mounted internally in each reel. Each wheel hub displacement may be individually selected or combined together to give the reel assembly different speed/torque characteristics. An operator panel allows control of the selection, speed and rotational direction of each reel.
