Abstract
A system for supplying power to a trolley chain. The system includes: a trolley chain, consisting of at least two trollies coupled with one another, wherein the trolley chain has a closed bus; and a stationary energy conductor along the track of the trolley chain. The stationary energy conductor consists of one or more successive segments, which are spaced apart from each other. The closed bus has several transmission heads, which are designed to supply the closed bus with electricity from the stationary energy conductor without contacting the stationary energy conductor, if they are within a pre-determined distance to the stationary energy conductor. During a journey of the trolley chain along the track, at each moment in time, at least one of the transmission heads supplies the closed bus with electricity from the stationary energy conductor.
