Abstract
A current collecting means in an aerial cableway system collecting electric power for driving a self-propelled aerial carriage, is capable of maximization of the lifetime of a current collecting shoe. The current collecting means comprises a current-carrying cable having at least a planar surface on the outer surrounding thereof and a current collecting shoe having a planar contacting surface to be urged onto the planar surface of the cable. The contact between the shoe and cable is carried out in both planar surfaces to prevent uneven wear of the shoe.
