Abstract
A self-mobile electrically powered machine is provided with an electric cable for supplying power to the machine. The cable is suspended between a rotatable turret, which may include a reel, on the machine and a portable cable tower spaced from the machine. From the cable tower, the cable extends to a remote power source. Constant cable tension is provided by the turret reel, or by a sheaving arrangement on the cable tower. The cable tower base is provided with a slot whereby the machine is used to move the tower to different locations while still being supplied with electricity therefrom.
