Rail Mounted Container Gantry Crane (RMG)
Rail Mounted Container Gantry Crane (RMG)
Henan Mine’s Rail Mounted Container Gantry Cranes (RMGs) are engineered to meet the rigorous demands of container terminals, rail yards, ports, and intermodal logistics hubs. These cranes are designed for high-throughput, high-precision operations, delivering fast container turnaround, advanced safety, and seamless automation integration.
Running on embedded rails, RMG cranes combine heavy-duty steel structure, customizable span and height, and smart motion control systems to optimize your terminal’s performance—without compromising on stability or long-term durability.

| Labor shortage and safety concerns | Optional semi/fully automated remote operation |
| Irregular yard layouts and custom gauge needs | Modular design, customizable span, gauge, and stack height |
Container Handling Crane Comparison Table
| Feature / Crane Type | RMG (Rail Mounted Gantry Crane) | RTG (Rubber Tyred Gantry Crane) | Portal Crane (Rail Mounted Portal Crane) |
| Mobility | 🚉 Fixed on embedded rails (long straight lanes) | 🚛 Mobile on rubber tires, can turn and move freely | 🚉 Fixed rails along quay or shipyard; limited lateral mobility |
| Power Source | ⚡ Electric-powered (via cable reel or busbar) | 🔋 Diesel, hybrid, or electric battery | ⚡ Electric (shore power or cable) |
| Typical Application | Container stacking in rail terminals, dry ports, and inland logistics hubs | Container yard handling in ports, terminals, or near-ship operations | Ship-to-yard cargo handling (containers, bulk, general cargo) |
| Span Width | Medium to wide span (18–40m) | Medium span (20–30m); adaptable | Varies; typically spans along quay (20–40m) |
| Load Capacity | 30t – 80t | 30t – 60t | 40t – 120t |
| Operational Flexibility | Low (fixed path; ideal for repeat routes and automation) | High (can move between blocks and lanes) | Moderate (quay/berth-specific usage) |
| Automation Readiness | ✅ High – Supports semi/fully automatic systems | ❌ Moderate – Limited automation due to tire motion complexity | ✅ High – Suitable for automatic container positioning and real-time diagnostics |
| Ground Pressure | Low – Rail-distributed load | High – Requires strong pavement | Low – Rail-distributed |
| Energy Efficiency | ✅ Very high – full electric and regenerative braking | ❌ Lower – Diesel or hybrid use | ✅ High – With electric drive and energy control |
| Initial Investment | Medium to high | Low to medium | High – Requires strong infrastructure |
| Maintenance Complexity | Low – Fewer moving parts; rail-based system | High – Tire, engine, steering, hydraulics require constant maintenance | Medium – Complex but centralized systems |
| Use Cases | Rail intermodal yards, dry ports, logistics zones | Seaport yards, mobile container stacking, temporary overflow zones | Ports and terminals with fixed berths, multipurpose quay operations |
| Henan Mine Solution Models | ✅ Available – Custom RMG series for terminals & inland hubs | ✅ Available – Custom RTG (upon request or partner build) | ✅ Available – Rail Portal Cranes for bulk and container yards |
