ABSTRACT:
A motorized traversing power unit includes a take-up reel, with a power supply cable which is anchored at one end adjacent one end of the path of the power unit and is wrapped in one direction around the reel, and a drive cable anchored at one end adjacent the opposite end of the path of the power unit and passing around the take-up reel in an opposite direction. Upon movement of the power unit in either direction, the paying out of one of these cables from the reel causes rotation of the reel for automatic take up of the other cable.
