Rail mounted gantry crane (RMG crane) is a high-efficiency container handling system designed to operate along fixed railway tracks. With its large span, high stacking capability, and advanced control systems, it is widely used in container terminals, rail transfer stations, and large logistics hubs for continuous, long-distance, and high-frequency container handling operations. As a type of heavy-duty container gantry crane, the rail mounted gantry crane is primarily used for loading, unloading, transferring, and stacking standard containers in railway transshipment yards and large storage areas. Its main structure consists of the main girder, rigid and flexible legs, trolley traveling mechanism, hoisting system, crane traveling mechanism, electrical control system, and operator’s cabin. With excellent stability, precise positioning, and strong load capacity, the rail mounted gantry crane plays a vital role in modern container logistics systems.
High Yard Space Utilization: The rail mounted gantry crane allows container stacking in multiple rows and several layers high within a fixed rail span. This significantly improves yard density and maximizes the use of limited terminal space, helping ports handle higher throughput without expanding land area.
Outstanding Handling Efficiency: With independent motions for hoisting, trolley travel, and gantry traveling, the crane achieves fast and smooth operating cycles. This greatly shortens container pick-up and drop-off times, leading to higher productivity and improved vessel turnaround speed.
Superior Reliability and Operating Stability: Designed with heavy-duty steel structures and premium components, the rail mounted gantry crane delivers stable long-term performance. Its rail-bound travel system offers consistent alignment and low vibration, while maintenance access points simplify servicing and reduce downtime.
Enhanced Safety Performance: Running on fixed rails provides better stability than rubber-tyred equipment. Combined with advanced electronic safety systems such as anti-collision devices, overload protection, and limit switches, it creates a safer working environment for operators and ground personnel.
Reduced Internal Traffic and Congestion: The crane operates directly over container stacks, minimizing the need for internal transport vehicles. This reduces yard traffic, lowers accident risks, and improves overall operational flow.
Lower Operating and Energy Costs: Electric drive systems, energy-efficient motors, and the absence of tire wear result in lower long-term operating expenses compared with mobile alternatives.
Environmental Advantages: As a fully electric solution, the rail mounted gantry crane produces zero local emissions, lower noise levels, and supports greener, more sustainable port operations.
Professional Project Coordination
From the initial planning stage to final handover, our expert engineering team manages the entire RMG crane installation process. We provide guidance on site preparation, foundation readiness, power supply planning, and safety arrangements to ensure a smooth and well-organized project execution.
Efficient Modular Installation Method
The main structural components of the RMG crane—including legs, main girders, and end carriages—are fully fabricated, pre-assembled, and tested at the factory. This modular design greatly shortens on-site work time and minimizes disruption to terminal operations. Depending on site conditions and crane size, the typical on-site installation period ranges from 4 to 8 weeks.
High-Precision Rail Installation Support
Accurate rail installation is critical for long-term stable operation of the RMG crane. We provide detailed rail foundation specifications and on-site technical supervision for rail alignment, level control, foundation grouting, and tolerance verification to ensure smooth and safe crane travel.
Strict Testing and Commissioning Procedures
Each RMG crane undergoes factory acceptance testing (FAT) before shipment and site acceptance testing (SAT) after installation. All mechanical, electrical, control, and safety systems are tested under both no-load and full-load conditions. Sensor calibration, positioning systems, and safety devices are verified to meet design standards.
Comprehensive Operator & Maintenance Training
We provide systematic training for crane operators, maintenance staff, and supervisors, covering safe operation procedures, routine inspections, fault diagnosis, and preventive maintenance to ensure efficient, safe, and long-term performance of the RMG crane.
