SYSTEM LAYOUT OF A LIFTING GEAR, ESPECIALLY FOR A CONTAINER CRANE FOR LIFTING LOADS AND METHOD FOR OPERATING SAID SYSTEM LAYOUT

摘要

The lifting gear comprises two motors (1, 1') that are connected to a transmission (6) via respective drive shafts (2, 2'), couplings (3, 3'), with fitted brake disks (4, 4') or brake drums, brakes (14, 14') and transmission input shafts (5, 5'). The transmission (6) drives cable drums (9, 9') via transmission output shafts (7, 7') and couplings (8, 8'). Said cable drums have a cable pull (12, 12') and fitted brake disks (10, 10') or brake drums and safety brakes (11, 11'). The inventive lifting gear is characterized by comprising, in the drive shafts (2, 2'), devices (13, 13') that completely or partially disconnect the motors (1, 1') from the transmission (6) when an excess load exceeds the predetermined load. They are monitored on both sides of the devices (13, 13') and the brakes (14, 14') and/or safety brakes (11, 11') are activated in the event of disconnection.
