Rail mounted gantry cranes
Rail mounted gantry cranes (RMGs) are manufactured to individual customer needs in a variety of different stacking heights and spans. Supplied with Liebherr's 8 rope reeving anti-sway and drive systems, the Liebherr rail mounted gantry crane delivers exceptional productivity and reliability.
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.
