摘要
The invention relates to an electrical power-supply duct comprising at least one duct section supporting a plurality of strip conductors arranged in order to be contacted by associated contact brushes (slides) carried by a moveable current-collecting trolley. According to the invention, the duct section (100) is made in the form of a beam having, in cross-section, a closed outline, on the outside of which are arranged longitudinal grooves (103), at the bottom of each of which a strip conductor (105, 105') is laid, and two ribs (106, 107) forming the craneways (rolling tracks) of the said trolley. Application especially to ducts for supplying electric power for a moveable crane-bridge trolley or for an electronic hoist carriage. IMAGE
