Abstract: A portable cable reel drive device which is removeably and adjustably attachable to large reels of varying widths and diameters having heavy metal cable or the like. The device includes a portable drive shaft having an adjustable reel hub engaging means, a hanger assembly for mounting and coupling the device to the reel itself, a shaft supporting device for supporting the shaft above ground and a tie down means for connecting and holding the shaft in place when it is being driven. The device is driven by a conventional, portable electric motor which is attachable to one end of the reel drive shaft. The device is especially useful for paying out heavy electrical cable on large reels to reduce the number of men required during the operation.
