Introduction of Rail-mounted Gantry Crane
Our heavy-duty Rail-Mounted Double Girder Gantry Crane is engineered for high-capacity container and cargo operations across large-span outdoor settings, including ports, intermodal rail yards, and open storage terminals. Built with a robust U-shaped portal frame, it offers exceptional leg clearance—up to 7 meters—enabling smooth handling of oversized freight and shipping containers under demanding A5 to A8 duty cycles.
With lifting capacities ranging from 5 to 500 tons and spans between 18 to 35 meters, the crane structure can be customized with or without cantilevers. The main girders are rigidly connected to end beams, ensuring structural integrity and alignment under heavy loads.
Features of Rail-mounted Gantry Crane
Key Components & Operational Design
The crane travels seamlessly on steel wheels along fixed ground rails, drawing power from the main electrical supply. Its core subsystems include the gantry frame, hoisting unit, trolley traverse assembly, and specialized container spreaders. Integrated inverter-driven motors and PLC controls enable precise load management and smooth acceleration.
Advanced Performance Features
Multiple RMG Configurations: We supply both top-running (trolley rotation) and under-hung (spreader rotation) designs, available in cantilever or non-cantilever models tailored to rail and terminal applications.
Enhanced Anti-Sway Control: A standard two-way flexible resistance anti-sway system is included, with optional frequency conversion micro-adjustment and electronic sway prevention for superior load stability and reduced container oscillation.
Smart Monitoring & Diagnostics: Equipped with an intelligent CMS for real-time oversight of operational metrics, fault alerts, and performance analytics.
Energy-Efficient Drive Systems: Utilizing vector frequency conversion with regenerative power feedback and torque balancing to lower energy consumption and improve motion control.
Automated Safety & Positioning: Core automation technologies include auto-positioning, intelligent box recognition, trajectory control, and dynamic safety scanning—supplemented by wind speed alarms and anti-collision systems.
Flexible Operation Modes: Supports manual, semi-automatic, fully automated, and remote-control operation to match varying workflow requirements.
Built to International Standards
All cranes are manufactured in compliance with GB/T 19683-2005, JT/T 566-2004, ISO, FEM, and JIS standards, ensuring reliability, safety, and global interoperability.

Applications of Rail-mounted Gantry Crane
Our rail-mounted container gantry cranes deliver high-performance handling solutions for intermodal freight operations, supporting both ISO shipping containers and wider railway-specific container types across global supply chain infrastructures.
Primary Operational Environments
Seaport & Terminal Container Management
Deployed at port facilities and quaysides, these cranes efficiently unload containers from vessels and transfer them to storage yards or land transport. Their high stacking capacity and precise trolley control help reduce ship berthing time and optimize terminal throughput.Intermodal Rail-to-Road Transfer Stations
Acting as a key link between rail and truck transport, the cranes enable smooth transfer of containers from rail flatcars to waiting trailers. Their wide span and customizable lifting height accommodate various railcar and truck configurations, supporting just-in-time logistics.Logistics Park & Container Yard Operations
Ideal for large-scale storage yards and distribution hubs, these gantry cranes maximize vertical stacking density and ground space utilization. Operators benefit from flexible organization of containers by type, destination, or priority—speeding up retrieval and loading processes.Rail Freight & Inland Container Depots
Specifically designed to handle broad-width rail containers, these cranes are integral to modern rail freight terminals. They support efficient train loading/unloading cycles and help maintain scheduling accuracy in high-volume rail corridors.Customs & Inspection Zone Handling
Used in secured areas for container sorting and movement, these cranes assist in customs inspection workflows by allowing quick repositioning and safe handling of containers during clearance procedures.
Adaptability Across Transport Modes
With compatibility across sea, rail, and road container standards, our rail gantry cranes form a versatile backbone for multi-modal cargo transfer—enhancing workflow continuity from port to inland destination.
