Abstract
Abstract A guide or feeder chain for power and supply lines is provided. The chain includes chain links that comprise two spaced-apart link members that are disposed parallel to one another and are interconnected by crosspieces. The chain links have a reciprocal pivot angle delimited by abutment inserts. Exposed sides of the chain links are covered by cover plates secured to the crosspieces. End links of the chain are connected via connectors to a fixed connection at one end and to a movable consuming device at the other end. Some of the crosspieces, along a portion thereof disposed between the link members, have an enlarged cross-sectional configuration. The abutment inserts are interconnected via stems that extend into corresponding notches of the link members. A curved cover element is telescopically guided on one side of each cover plate. One end of each end link is embodied to connect to a link member, and the other end is provided with a pocket for the insertion of variously shaped connectors.
