Krankatze

Description: A crane trolley with hoist usually moves along the bridge girder, unless the gantry crane features a rail-mounted slewing crane. Small running gear such as on crane trolleys usually feature central drives with wheels connected to rigid or articulated shafts. Bridge cranes can be equipped with one or more crane trolleys, with single girder bridge cranes usually fitted with under-running trolleys on an I-beam girder.
