Rail-mounted container gantry cranes

Rail-mounted container gantry cranes (RMG) is a specialized yard container handling machine. It can travel on rail by means of the yard power, and lift an stack containers in the yard area with the equipment of the 20' or 40' telescopic spreader (or twin-lift spreader if needed). The RMG has the advantage of being driven by electrical power, clean, bigger lifting capacity, an high gantry traveling speed with cargo. The RMG consists of lifting mechanism, trolley traversing mechanism, gantry mechanism and sway-dampening mechanism.

It can travel on rail by means of the yard power, and lift an stack containers in the yard area with the equipment of the 20' or 40' telescopic spreader (or twin-lift spreader if needed). The RMG has the advantage of being driven by electrical power, clean, bigger lifting capacity, an high gantry traveling speed with cargo. The RMG consists of lifting mechanism, trolley traversing mechanism, gantry mechanism and sway-dampening mechanism.

Rail Mounted Double Girder Container Gantry Crane is suitable for loading and unloading of large span, frequently railway freight yard, port, open storage, container transfer station etc.. This machine adopts U type gantry, its legs headroom large (nearly 7 meters). It is suitable for heavy bulky cargo and container handling operations, with frequent high-level work, A5 ~ A8. The weight of 5 to 500 tons, the span of 18 to 35 meters, the girder can be designed have cantilever and no cantilever, the end of two main beam connected with end beams to meet the high level requirements.

Case

Application

The Rail Mounted Gantry Crane (RMG) is a specialized material handling equipment used in ports , container terminals, and intermodal yards for efficient cargo movement. Rail Mounted Gantry Crane is designed specifically for handling containers and heavy loads, such as pallets and bulk materials. They are powered by electricity or diesel.

Rail Mounted Gantry Crane is commonly used for container loading and unloading, cargo transportation within a port or terminal, and container stacking in depots or yards. They are equipped with spreader or grab attachments for secure lifting and movement of containers or other types of freight.
