Simultaneous motion of gantry, trolley, hoist and swivel
Liebherr RMGs have the option of a rotating trolley. Loading of a train often sees the doors of the container facing each other for security.
Available with stacking heights of up to eight containers high, with custom spans in excess of 70 metres and outreaches up to 20 metres, each RMG features Liebherr’s crane management and reporting software and is designed for manual, semi-automatic or automatic operation. The application of Liebherr’s eight rope reeving anti-sway system and simultaneous motion of all drives leads to increased productivity when compared with alternative designs.
