Abstract

An energy supply chain for guiding conduits such as cables, hoses or the like between a stationary and a movable connection point or between two connection points which are movable relative to each other comprises a plurality of hingedly interconnected chain link members forming a space for receiving the conduits extending therethrough. The chain includes at least one bar which is resilient about its longitudinal axis and which extends in the longitudinal direction of the chain, more particularly in the receiving space thereof. Upon pivotal movement of the chain link members relative to each other the bar produces return forces which oppose the pivotal movement.
