Rail mounted gantry crane design

Zhonggong provides professional rail mounted gantry crane for sale, our rmg
cranes brings together decades of experience in crane design to achieve high
performance, high reliability and operational accuracy, while significantly
reducing operating costs and energy consumption.

We can tailor rmgc crane to your specific operational needs.

(1) 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.

(2) 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.

(3) 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, and has a certain
stiffness.
