Abstract
Apparatus for carrying one or more power conduits to a movable power consumer includes one or more power supply chains, a carriage between static and dynamic portions of the chain and movable in response to movement of the power consumer via a sheave and cable carriage drive and having rollers positioned in response to movement of the power consumer to support a dynamic portion of a power supply chain when it sags in a chain guide tray as a result of the chain travelling beyond its self-supporting travel distance. The carriage rollers have a radius substantially less that the predetermined bend radius of the chain so that a compact, light-weight, low center-of-gravity carriage is provided for movement in a chain guide tray.
