Abstract

A guide or feeder chain for power and supply lines is provided. The chain includes chain links formed from two spaced-apart side pieces or link members that are disposed parallel to one another and are interconnected via crosspieces. Successive chain links are pivotably interconnected where they overlap one another. So that the chain links can slide on one another without becoming worn or generating noise, sliding skids are detachably secured to narrow sides of the side pieces or link members.
