Abstract
The present disclosure concerns a crane, in particular a tower crane, with a jib from which a load hook can be raised and lowered via a hoisting cable, and with an electric power supply to the load hook and/or to a trolley that may be movable along the crane jib. According to the disclosure, the electric power supply to the load hook and/or to the trolley is at least partly conducted by a running cable which transmits tractive forces for the crane operation.
