Rail-mounted Container Gantry Cranes

Rail-Mounted Container Gantry Cranes (RMG) are specialized yard container handling cranes.

RMG crane travels on rails to lift and stack 20a or 40a containers in the yard area by means of the yard power. The container is lifted by a telescopic spreader attached to cables. Rail mounted container gantry cranes come in a variety of models with different spans and overhangs.

RMG crane consists of lifting device, trolley traversing device, gantry travelling device and sway-dampening device. The lifting, gantry and trolley devices are normally equipped with AC frequency conversion control system. The lifting device is of single drum type,and it can also be designed to be double drum type if needed.

RMG cranes are specifically designed for intensive container stacking due to its automation and less need for human handling. Compared to the Rubber Tyred container Gantry crane (RTG), the RMG crane has the advantages of being driven by electrical power, cleaner, bigger lifting capacity, and higher gantry traveling speed with cargo. Rail-Mounted Gantry cranes are particularly effective for rail/road transhipments of large quantities of containers.

The following items are for usera s selection according to their own needs:
* Trolley slewing mechanism. Normally the trolley can be slewed easily between -10 ~ + 190 degrees. If needed, continuous slewing can be realized.
