Rail Mounted Gantry Crane
Rail mounted gantry cranes, also known as RMG, are large-scale terminal gantry cranes that are often used for loading and unloading containers. We can provide customers with customized lifting solutions according to the requirements of different heights and spans.
-
Main beam structure
The main girder structure is composed of two box end girders and the frame girder is supported on the rigid and flexible legs. At present, the partial rail box beam is often used, the high strength bolt or welding method is used to connect the main beam and the rigid leg, and the twisted connection mode is used to connect the flexible leg. For the convenience of installation of RMGC cranes, the connection between the main beam and the end beam is generally connected by high strength bolts.
-
Door leg structure
For small and medium span rail container gantry crane, both rigid and flexible door legs adopt box structure. For the long-span crane, the three-degree-of-freedom dumpling connection is adopted for the connection between the flexible leg and the main beam, and a synchronous detection device is set up.
-
Trolley structure
The structure of the running trolley is different according to whether the hoisting mechanism is of wire rope drum type or telescopic rigid frame type, and the combined structure of box girder and grid is generally adopted. The structure of the running trolley takes into account the arrangement of the hoisting mechanism and the running mechanism of the trolley, which ensures high stiffness.
