Abstract
An electrical cable management device for use in mining and other applications where there are size restrictions on equipment. The device is a round stationary drum, around which travels a carriage for winding, unwinding and storing hot electrical cable. The device is mounted on skids and is portable and can be located away from the mining activity while still being able to manage and control the winding and unwinding of electrical cable in response to movement of the mining equipment. The device does not require electrical split ring connectors, rotating collector rings, brushes or the like, but provides a continuous cable from a power source to the moveable mining equipment. The orbiting carriage is driven by an electric motor for winding cable and automatically becomes free wheeling when cable is unwound from the drum.
