Detailed Product Description

Rail-mounted gantry crane

Rail-mounted gantry crane(RMG) is a specialized yard container handling machine. It can travel on rail by means of the yard power, and lift and stack containers in the yard area with the equipment of the 20 or 40 telescopic spreader (or twin-lift spreader if needed). Compared with the rubber-tyred gantry crane(RTG), the RMG has the advantages of being driven by electrical power, clean, bigger lifting capacity, and high gantry traveling speed with cargo.
The RMG consists of lifting mechanism, trolley traversing mechanism, gantry mechanism and sway-dampening mechanism.
The lifting, gantry and trolley mechanisms are mostly equipped with AC frequency conversion control system. Normally the lifting mechanism is of the single drum type. It can also be designed to be double drum type if needed.
The following items are fro users selection according to their own needs;
* Trolley slewing mechanism. Normally the trolley can be slewed easily between
-10°and +190°. If needed, continuous slewing can also be realized.
* RMGs with overhanging en beam, which reaches beyond gantry traveling rail.
* RMGs with different rail gauges.
* RMGs with generator.
* two-direction anti-sway system(eight(8)-rope system, refer to left)
