1) Festoon
A configuration of small trolleys, support track, and electirical cable utilized to provide power to material handling devices while keeping the power cable out of harm's way. The cable is looped or "festooned" by attaching to trolleys supported on a track. Thsi arrangment allows this cable to be "bunched" in an accordian-like fashion so as to keep the cable from becoming entangled in the movement pattern of the device it serves. Often utilized to "stretch" cable across the bridge of an overhead traveling crane.
