Words are escaping me - literally.
What do you call a bundle or loop or coil of power/control cabling that connects to an apparatus which moves, pivots, or telescopes during operation where the cable is designed to accommodate the motion of said apparatus by some means of extension/retraction?
You see this in various industrial apparatus such as variable geometry conveyor belts, gantry cranes, draw out equipment in racks or electrical switchgear, airport jet bridges, etc;
There are several different types of designs, but they all have some means of accommodating non-trivial amounts of motion in the connected device. The most common designs usually have loops of extra cable hanging from pulleys or sections of conduit/duct.
Here is a good picture that shows the kind of thing that I am asking about. In this instance it is the power and control cable for an overhead gantry crane
There is a particular term for this kind of arrangement but I cannot for the life of me recall what it is.
