The RMG (Rail Mounted Gantry Crane) is a high‑capacity, rail‑guided container handling system designed for container terminals, intermodal rail yards, and logistics hubs requiring high‑density stacking, fast retrieval, and reliable operation. Unlike rubber‑tyred gantry cranes (RTGs), the RMG travels on fixed rails, offering greater stability, higher stacking capacity (up to 1‑over‑6 or 1‑over‑7 containers high), and the ability to operate fully automated with precise positioning. RMGs are typically used for stacking containers in storage blocks, loading/unloading trains and trucks, and serving as a transfer point between different transport modes.

1. Container Terminal Stacking Yards (Dense Storage) High‑Density Storage: Stacking laden containers up to 1‑over‑6 (6 high) in terminal storage blocks, maximizing land utilization. Truck Interface: Loading/unloading trucks at the landside transfer zone with precise, fast cycles. Vessel Discharge Support: Receiving containers from ship‑to‑shore (STS) cranes and stacking them in designated yard rows.,

2. Intermodal Rail Yards Railcar Loading/Unloading: Lifting containers directly from railcars (single or double‑stack trains) and placing them onto trucks or yard storage. Cross‑Docking: Rapid transfer of containers between rail and road modes with minimal handling time. Rail Yard Management: Serving multiple rail sidings with wide‑span RMGs, covering several tracks simultaneously.

3. Inland Ports & Logistics Hubs Barge Interface: Transferring containers between barges and trucks or storage, where rail‑mounted precision is beneficial. Bonded Warehouses: Handling containers in customs‑controlled areas with automated tracking and security. Cross‑Border Facilities: Managing container flow between different transport modes (rail, road, barge) with high throughput.

4. Port Terminal Expansion & Automated Yards Fully Automated Stacking: RMGs equipped with remote control, laser/radar positioning, and automatic spreader control for unmanned operation. Automated Truck Lanes: Using OCR and automated gantries to handle truck arrivals/departures without manual intervention. Integration with AGVs: RMGs interface with automated guided vehicles (AGVs) for seamless container hand‑off.

5. Heavy Industry & Steel Service Centers Heavy Cargo Handling: Using RMGs with spreader beams or hooks to handle steel coils, plates, and project cargo (not just containers). Rail‑Fed Warehouses: Serving rail sidings inside steel mills or fabrication plants, unloading raw materials and loading finished products. Large Component Storage: Stacking heavy industrial components (turbine blades, transformers) on specialized racks.

6. Military Logistics Bases Containerized Supply Handling: Loading/unloading military containers from railcars and trucks in secure, high‑density storage yards. Expeditionary Railheads: Deploying RMGs at temporary railheads to support rapid force projection. Ammunition & Equipment Storage: Handling ISO containers with ammunition or heavy equipment in controlled areas.
