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.
2) Electrification
The track mounted conductor system by which the moving equipment receives its electrical power. All of the electrical components that go into providing power to an electric overhead crane or jib crane. These components may include power bar, collectors, collector rings, pendent stations, and tagline/festooning.
3) Tagline
An electrical conductor system employing flexible cables which are festooned along the bridge or runway. The cable is attached to trolleys or hooks which operate on a rigid bar or tight wire along the entire bridge width or runway length. This arrangement serves to keep the cables "out of the way" of the crane and hoist movement.
