Large Span and Cantilever Design
RMG's design breaks through the wheel pressure limitations of tire-mounted cranes, maximizing storage area coverage through large spans and single/double cantilever structures. Its track gauge can reach over 35 meters, and front and rear cantilevers can be designed to cover railway lines or truck access routes according to customer needs. This structure makes it particularly suitable for "sea-rail intermodal" scenarios, such as the RMG provided by RICON for València, directly serving the railway hub connecting the port and the inland.
Ultimate Speed and Control Precision
In the core indicators of high-frequency operations, RMG overwhelmingly surpasses RTG, which is the fundamental reason why it has become a core piece of equipment in automated terminals. As shown in the table below, RMG's advantages in speed, precision, and lifespan make its total life cycle cost more competitive:
| Performance Indicators | RMG Parameters | RTG Parameters |
| Full-load lifting speed | 13-23 m/min | 10-18 m/min |
| Trolley travel speed | 70-240 m/min | 50-120 m/min |
| Positioning accuracy | ±3-5 mm | ±20-50 mm |
| Stacking capacity | 1-over-7 | 1-over-6 |
| Design life | 25-30 years | 15-20 years |
Limitations and Investment Threshold of RMG: The biggest constraint of RMG lies in its high initial infrastructure investment (rail laying, power facilities) and lack of mobility. Once installed, it cannot cope with temporary changes in yard layout. Therefore, despite its extremely low operating costs, RMG is more suitable for large hub ports with stable freight volumes, long-term planning, and a pursuit of high automation, such as Shanghai Yangshan Port or Singapore Port.
