Abstract
A storage reel for evenly winding and unwinding heavy electrical feeder cable is mounted on the side of a mining vehicle. The storage reel is mounted so as to be stationary on the vehicle. The orbital carriage revolves around the reel evenly winding or unwinding the cable. The reel is shaped in an elongated oblong to maximize the cable storage for use on restricted low profile mining equipment. The device is suited for use on vehicles in mining operations and does not require the use of split rings, rotating collector rings, brushes, or the like for electrical connection, but permits power to pass through the cable from the power source to the vehicle without intervening electrical connectors.
