Adhering to the philosophy of "Quality builds brands, integrity shapes the future", it provides customized RMG equipment and full-life-cycle maintenance services for container yard projects.
What is an RMG rail-mounted container gantry crane?
Rail-mounted Container Gantry Crane (RMG) is a gantry crane specially designed for container stacking and transfer. The whole machine travels directionally along pre-laid steel rails and is equipped with dedicated telescopic container spreaders to complete lifting, stacking and on-site transfer operations of 20ft, 40ft and 45ft containers.
The equipment is available in two structural types: single girder and double girder. The double-girder RMG manufactured by Henan Mine features higher load capacity and smoother operation, and is widely adopted in high-throughput heavy-duty yards. The single-girder model is mostly applied to medium and small yards and empty container storage areas. The machine supports multiple control modes including cabin operation, wireless remote control and fully automatic unattended operation, suitable for the renovation of traditional yards and new smart terminal projects.

Core Advantages of Henan Mine RMG Rail-Mounted Container Gantry Crane
Precise positioning and adaptability to automated upgrading
The equipment travels along restricted track routes with small travel deviation. It can be equipped with laser positioning, anti-collision systems and PLC intelligent control systems, and can easily connect to the yard WMS management system to realize unmanned container access operations and build intelligent container storage yards.
Lower long-term operating costs, energy conservation and environmental protection
Henan Mine's mainstream RMG adopt power supply via trolley wires / cable reels. Unlike fuel-powered RTG rubber-tyred gantry cranes, they consume no fuel and produce no exhaust pollution. The steel wheels travel along rails, eliminating ongoing expenses caused by tyre wear and regular replacements, delivering outstanding cost efficiency for long-term high-frequency operations.
Stable operation under heavy load and reduced container cargo damage
The rigid track effectively restrains the shaking of the complete machine during lifting. It delivers excellent torsional resistance when transporting fully loaded heavy containers, greatly lowering risks of container collision and cargo damage, and meets the stringent operation standards for customs supervised yards and heavy-duty railway container transportation.
All-weather durable design, suitable for complex outdoor environments
The complete machine is standard-equipped with professional wind-resistant anchoring devices and lightning protection systems. For working conditions featuring low temperatures in northern regions and rainy, humid weather in southern regions, Henan Mine can customize low-temperature anti-corrosion and rust-proof coating solutions. The equipment supports 24-hour non-stop all-weather operation and can meet heavy-duty standards of working class A6 and A7.
Main Application Scenarios of RMG
- Railway Multimodal Transport Container Freight Yard
- Inland Dry Port, Customs Supervised Container Storage Park
- Inland river ports and inland waterway container terminals
- Container Turnover Yard of Large Logistics Group
- Special Container Yard for Import and Export of Manufacturing Enterprises
Key Steps and Procurement Process of RMG Cranes
Contact the technical team of Henan Mine for quotation. It is recommended to organize the following on-site information to ensure the scheme accurately matches the working conditions:
- Rated Lifting Capacity: Distinguish empty container operations and full loaded container operations, and confirm the maximum total weight of the lifted containers.
- Effective span: the total width of the container stacking area inside the gantry frame.
- Lifting height: Determined according to the planned stacking layers of containers.
- Operating class: Continuous daily operation of more than 8 hours; A6/A7 heavy-duty operating class is preferred.
- Control Configuration: Choose one from manual cab, remote control and fully automatic unmanned system.
- Power supply scheme: power supply via sliding contact line or cable reel.
- Environmental customization requirements: low-temperature anti-freezing, anti-corrosion coating, heightened wind protection devices, supporting video surveillance, etc.
