The Rail Mounted Container Gantry Crane (RMG) is a specialized, high-efficiency container handling solution manufactured by Henan Mine, designed for loading, unloading, stacking, and transferring ISO standard containers in ports, railway terminals, and large container storage yards . This crane features a robust double-girder or truss-type main beam structure supported by rigid and flexible outriggers, traveling on fixed ground rails to provide exceptional stability, high positioning accuracy, and the ability to span multiple container rows and rail tracks .

The crane is equipped with a dedicated telescopic container spreader compatible with 20ft, 40ft, and 45ft containers, an advanced electrical control system with full digital AC frequency conversion and PLC control, and a bi-directional flexible resistance anti-sway system for precise load positioning . Typical specifications include lifting capacity from 30.5 to 60 tons (standard) and up to 100+ tons for heavy project cargo, spans from 25 to 50+ meters, lifting heights from 12 to 25+ meters (stacking up to 1-over-6 or higher), working duty class A6 to A8, lifting speeds of 25–35 m/min (laden) and 50–70 m/min (empty), and power supply options including conductor bar, cable reel, or diesel generator .

The crane supports multiple operation modes including cabin control, remote operation, and fully automated (ARMG) with integration capability to Terminal Operating Systems (TOS), featuring intelligent functions such as inching movement, electronic anti-sway, zero speed hover, multi-trolley synchronization, regional load limit, and wireless expansion for full lifecycle management .

Rail-mounted container gantry cranes (also known as rail-mounted container gantry cranes, abbreviated as rail-mounted hoists) are large-scale loading and unloading equipment that run along fixed tracks. They are mainly used for efficient loading, unloading, handling and stacking of containers in ports, railway freight yards and container storage areas.

Core Applications – Rail Mounted Container Gantry Crane
1.Ports & Large Container Terminals – Loads and unloads ISO containers from ships and transfers them to trucks or stacking areas with high-speed lifting and trolley travel, supported by U-type or double-cantilever legs allowing vehicles to pass under the crane .
2.Railway Intermodal Terminals – Transfers containers between freight trains and trucks or storage stacks at inland rail depots, with span capable of covering multiple railway tracks and optional cantilever design extending reach beyond rail centers .
3.High-Density Container Storage Yards – Stacks containers 1-over-5 to 1-over-8 tiers high over large areas, maximizing storage density for long-term container storage facilities and inland container transit stations .
4.Automated Container Terminals (ARMG) – Performs fully automated, unmanned container stacking and retrieval operations guided by GPS, laser scanners, and optical character recognition (OCR), integrating with Terminal Operating Systems for 24/7 productivity .
5.Mixed Container Handling – Handles standard ISO containers (20ft, 40ft, 45ft, HC) and specialized containers (reefers, open-top, flat-rack) using manual, semi-automatic, or fully automatic twistlock spreader systems .
6.Environmentally Friendly Port Operations – Operates on electric power via conductor bars or cable reels with zero emissions and energy regeneration technology, reducing carbon footprint while lowering long-term operational costs compared to diesel-powered alternatives .
