Liebherr Rail Mounted Gantry Cranes

Product catalog summary

Technical Specifications
Rail Mounted Gantry Cranes (RMG) are designed with a gantry span ranging from 22 to 70 meters and a lifting height from 9.2 meters for 1 over 2 up to 26.9 meters for 1 over 8. The cantilever can extend from 0 to 20 meters, and the travel wheel gauge is between 16.5 and 18.2 meters. The cranes support a Safe Working Load (SWL) of 40.6 to 50 tons for single lifts and 50 to 65 tons for twin lifts. The design adheres to F.E.M. U7-Q2-A7 classification, withstanding in-service wind speeds of 72 km/h and out-of-service speeds of 151.2 km/h, and operates in temperatures from -45°C to +45°C.

Design and Operational Advantages
RMGs are suitable for both port and rail terminals, offering increased yard capacity and reduced emissions. They require minimal maintenance and are energy-efficient due to their electric supply. The cranes feature a Liebherr anti-sway system with eight rope reeving, reducing energy consumption and maintenance needs while enhancing productivity.

Motors and Control Systems
The cranes are equipped with motors sourced from reputable European manufacturers, ensuring maximum torque and power. The control system, developed by Liebherr, is robust and reliable, featuring a modular electronic design to maximize availability and minimize the need for skilled personnel. The system includes features like minimal spreader positioning times, anti-skew, and no additional ropes or devices.

Options and Features
Optional features include a rotating machinery trolley, interface with terminal operating systems, energy chain systems, non-contact anti-collision systems, and automation options. The diagnostic and management system provides a comprehensive overview, including crane status, drive data, wind speed history, and maintenance logs.

Additional Information
Liebherr offers a worldwide service network, extensive training, and a purpose-built design and production facility in Ireland. The company ensures responsibility for all aspects of crane design, production, and service, eliminating compatibility issues.
