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.
El accionamiento eléctrico adopta la tecnología única de conversión de frecuencia de CA completamente digital y control de regulación de velocidad PLC con control flexible y alta precisión. Los componentes estándar adquiridos de marcas de renombre nacionales y extranjeras garantizan la calidad general.
The design, manufacture, and inspection comply with Chinese standards and international standards such as FEM, DIN, IEC, AWS, etc. Weihua’s RMG has the characteristics of multiple functions, stability, reliability, a wide range of operation, easy operation, and maintenance.
Our main products include RMG for railways: upper rotating (trolley rotation), lower rotating (spreader rotation), cantilevered, and non-cantilevered.
Rail mounted gantry crane mainly consists of a metal structure (main beam, outrigger, traveling cart), hoisting mechanism, trolley running mechanism, trolley running mechanism, electrical control system, and safety protection devices.
