INTRODUCTION

A Rail-Mounted Container Gantry Crane (RMG) is a specialized heavy-duty gantry crane designed for high-density container handling and stacking along fixed rail tracks. Powered by electric grid supply, it spans across multiple container tracks and truck driveways, utilizing automated or semi-automated container spreaders to move standard ISO containers ( $20ft}, 40ft, 45ft$ ) with exceptional speed, stability, and positioning precision.

APPLICATION SCENARIO

Container Freight Terminals & Sea Ports: High-density stacking and transfer of 20ft, 40ft, and 45ft standard ISO containers in primary container yards.
Inland Container Depots (ICD) & Dry Ports: Efficient container storage, customs clearance inspection yards, and consolidation hubs.
Intermodal Railway Freight Hubs: Direct transferring of containers between railway flatcars, road trucks, and yard storage lanes.
Automated Container Terminals (ACT): Serving as the core lifting equipment for fully or semi-automated yard stacking blocks (ARMGs).

ADVANTAGES

Advantage FeatureTechnical & Operational ValueSuperior Yard Density & Stacking CapacityMaximum Land Utilization: Capable of high stacking heights (typically 1-over-5 to 1-over-7 containers) and wide spans (up to 14+ container rows wide), maximizing terminal storage capacity per square meter.Fully Electric & Eco-FriendlyZero Direct Emissions: Powered directly by electricity via cable reel or conductor bar, drastically lowering energy costs and operating quieter compared to diesel-driven RTGs (Rubber-Tyred Gantry Cranes).High Precision & Automation ReadyPrecise Rail Guidance: Fixed steel rails remove steering deviations, enabling smooth integration with anti-sway systems, auto-positioning, and remote/fully automated operations (ARMG).

FAQS

01What is the main difference between an RMG and an RTG (Rubber-Tyred Gantry Crane)?

RMGs run on fixed steel rails and are powered directly by electricity, offering higher structural stability, wider spans, higher stacking capacity (up to 1-over-6), zero direct emissions, and superior automation. RTGs move on rubber tires and offer greater yard flexibility to move between different stacking blocks, though they traditionally rely on diesel power or hybrid/cable-reel power.

02Can an RMG crane be fully automated?

Yes. Because RMGs run along fixed rail tracks, their path is completely predictable. Equipped with target positioning systems, laser sensors, camera vision, and Anti-Sway control, RMGs are easily upgraded to ARMGs (Automated Rail-Mounted Gantry Cranes) for unattended 24/7 operations controlled remotely from an ops center.

03How does an RMG handle sway during high-speed hoisting and traveling?

RMGs use dynamic Mechanical Anti-Sway Systems (e.g., 8-rope or 4-rope rigid reeving layouts) combined with electronic/VFD sway-control algorithms to quickly stabilize the spreader, enabling fast, precise millimeter-level container positioning without waiting for natural pendulum damping.
