Rail Mounted Gantry Crane Manufacturer in China | RMG Container Crane Solutions
Rail mounted container gantry crane (abbreviated as RMG, also known as container rail mounted gantry crane or rail mounted gantry container cranes) is a heavy-duty container handling crane that travels on fixed rail tracks within container yards, railway terminals, intermodal facilities, logistics centers, and coastal freight yards.
It is designed for efficient, high-precision container handling at:
- Deep-sea terminals
- Near-shore terminals
- Inland terminals
- Railway hubs
- Intermodal logistics facilities
Unlike rubber-tyred gantry cranes (RTG), RMG is fully powered by grid electricity and operates on steel wheels running on steel rails, offering:
- Zero emissions
- Low operating costs
- High automation potential
- Long service life
