Description
The rail mounted gantry crane is applicable to remove, load, and unload international standard containers. It is a highly efficient loading and unloading equipment, mainly for in ports, docks, and inland container yards. The main function is stacking, handling, and transshipment of containers from ships to land transport. The main beam is the core structure that bears the weight of the container. It is usually a box-shaped section to ensure strength. Its outriggers connect to both ends of the main beam. Thus, it could support the entire RMG crane and allow it to move along tracks on the ground.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Superior Stability & Heavy Load Capacity
Operating on fixed ground rails, RMGs provide exceptional stability and minimal ground pressure, supporting lifting capacities from 30.5 tons up to 100+ tons . The robust double-girder or truss structure, fabricated from high-grade steel, ensures durability in demanding 24/7 operations .
Large Span & Full Coverage
With spans ranging from 25 to 50 meters (customizable beyond 70 meters), the crane covers multiple rail tracks and storage rows in a single pass . It can travel along the entire yard length, enabling uninterrupted operations without repositioning railcars .
Track tPrecision Control & Anti-Sway Technologyype
Equipped with PLC and variable frequency drives (VFD), RMGs deliver smooth acceleration, precise positioning (±50mm), and micro-speed movements . Advanced anti-sway systems (e.g., 8-rope reeving or Active Load Control) actively eliminate container swing, enabling accurate alignment and rapid cycle times .
Automation-Ready & Energy Efficient
RMGs support a clear evolution path from manual to semi-automated and fully automated unmanned operation, with integration to Terminal Operating Systems (TOS) via GPS, laser scanners, and OCR . Power regeneration systems and lightweight designs si
