摘要

A crane includes a crane structure defining a substantially vertical rotation axis; a boom connected with a first end to the crane structure to be rotatable about the vertical rotation axis; a trolley moveable along the boom in longitudinal direction of the boom; a hoisting cable and a load connector. The load connector is arranged at a free end of the hoisting cable to be connected to a load for hoisting purposes. The trolley includes a cable guide to guide the hoisting cable and an attachment configured to temporarily attach the load connector to the trolley to fix the position of the load connector relative to the trolley.
