RMG Crane
The Rail Mounted Gantry Crane (RMG) is a high-efficiency handling solution purpose-built for container terminals, rail freight stations, and intermodal hubs. Operating on fixed ground rails, the RMG delivers high throughput within limited yard space through precise positioning and high-density stacking. Fully electric-powered, it produces zero emissions and low noise, offering significant energy and environmental advantages. Lifting capacities range from 30.5 to 65 tons, with customizable span and lifting height to match specific yard layouts. The crane handles 20ft, 40ft, and 45ft ISO containers for storage and transfer operations--45. Depending on terminal automation requirements, RMGs can be configured for manual cabin operation, remote control, or fully automated (ARMG) unmanned operation, with seamless integration into Terminal Operating Systems (TOS)-10.

Customer Praise
"We've been running this boat hoist crane daily for over a year now, and it has been rock solid. Lifting is smooth and stable—the anti-slip slings give us real confidence that hulls won't get damaged. Maneuvering in tight yard spaces is surprisingly easy, and the corrosion protection has held up beautifully even with constant saltwater exposure. For the price, the build quality and reliability far exceeded our expectations. Very satisfied with the investment."

“Anti‑sway control is excellent — containers stay stable even at higher travel speeds. The 90‑degree in‑situ rotation and flexible steering modes let us work efficiently in a very tight yard. Hybrid power keeps fuel costs under control, too. Overall, very solid reliability for the price.”
customer
Arif bin Hassan
"Fast and precise. Our container handling is much quicker now, and the crane just works day in and day out with very few issues."
customer
Dmitri Volkov
“The dual‑trolley configuration is a genuine advantage for heavy block handling — the lower trolley passes right beneath the upper trolley for flexible positioning. Multi‑point synchronized lifting keeps everything perfectly stable, and it handles A7 duty without issue.”
customer
Terrence
“We ordered six RTG units and the performance has exceeded expectations. The hybrid power technology cut our energy consumption significantly, and the anti‑sway system keeps container movement remarkably stable during travel. The 90‑degree in‑situ rotation and flexible steering modes let us operate efficiently in tight yard configurations. Excellent build quality, and the delivery was faster than any previous equipment purchase we‘ve made.”
customer
Ethan
"Smooth operation and very reliable. It covers the whole dock with ease and handles whatever we need to lift without any trouble."
customer
Oliver
"The compact European double girder design saved us valuable workshop space, and the low‑headroom configuration fits our building height perfectly. Lifting and travel are smooth with precise VFD control—ideal for handling sensitive workpieces. A5 duty rating matches our production rhythm, and the CE documentation was complete."

Frequently Asked Questions – RMG Cranes
How do I choose between an RMG and an RTG crane?
add subtract
RMG runs on fixed rails with all-electric power, offering higher stacking density and lower operating costs—ideal for high-throughput permanent yards. RTG uses rubber tires for flexible movement but typically has lower efficiency and higher fuel costs. Choose RMG for maximum productivity and energy savings.
What technical parameters are essential when specifying an RMG?
add subtract
Four key parameters: Lifting Capacity (30.5–65t under spreader), Span (typically 25–50m+), Lifting Height (1-over-5 to 1-over-6 stacking), and Work Duty Class (A6–A8 for continuous operation).
Can the RMG crane be customized to my yard layout?
add subtract
Yes. Span, lifting height, cantilever outreach, power supply, and control mode (manual, remote, or fully automated) can all be customized to match your specific terminal configuration.
Do you provide installation and after-sales support?
add subtract
Yes. We offer remote or on-site installation guidance, 24-hour technical support, and genuine spare parts supply to ensure long-term reliability.
Can an RMG crane be upgraded to full automation later?
add subtract
Yes. Many RMG models are automation-ready, allowing you to start with manual or remote operation and upgrade to fully automated (ARMG) operation when your terminal requires it.
