ABSTRACT:
The invention proposes an electric overhead trolley system in which a travelling gear (14) is provided with a motor-driven driving wheel (16) and at least one auxiliary wheel (30) interacting with an auxiliary track (28), at least in certain sections, which auxiliary wheel contributes in transmitting the drive force to a track (10) so that ascending and decending track portions can be run through with less problems.
