Rail-Mounted Gantry (RMG)

• High-Precision Intelligent Anti-Sway: Utilizes an eight-rope anti-sway winding system combined with active load control technology to limit container sway within ±50mm. Enables micro-displacement adjustments for precise alignment with trucks, rail cars, or stacking positions, eliminating manual repositioning and boosting operational efficiency by 35%.
• Automatic Positioning & Recognition: Equipped with laser scanning recognition and dual GPS+BeiDou positioning systems, achieving positioning accuracy of ±10mm. Automatically identifies container numbers and types, uploading data in real-time to management systems. Supports automated lifting path planning for unmanned remote operation.
• High-Efficiency Cycle Operations: Lifting speed 0-20m/min, trolley speed 0-30m/min, and gantry speed 0-40m/min—all with variable frequency drive for smooth, shock-free starts/stops. Telescopic spreader changeover ≤15s enables rapid adaptation to various container sizes, reducing single-container handling cycles to under 60 seconds.

• Multi-layered Wind Protection: Equipped with wind clamps, top rail clamps, wind tie-downs (tie rods), and anchoring devices for quadruple safeguards. Ensures no slippage at wind speeds of 15-35 m/s and no overturning at 35-55 m/s, meeting the highest standards of the “Management Regulations for Large Port Machinery Against Gusts and Typhoons”;
• Intelligent Wind Warning System: Equipped with an anemometer featuring recording and alert functions, it continuously monitors wind speed changes. When wind reaches 15 m/s (Force 7), it automatically issues a warning prompting work cessation and activating wind protection mechanisms. Upon exceeding critical wind thresholds, it automatically cuts operational power and locks wind protection devices.
• Structural Wind Resistance Optimization: The main beam features a streamlined design to reduce wind resistance coefficient. Outriggers are secured to the foundation with high-strength bolts, complemented by track-end stops to further enhance wind stability, making it suitable for windy environments in ports and open-air yards.

• Energy recovery system: Regenerative energy generated during load descent and deceleration braking is fed back to the grid via active filters, boosting energy efficiency by ≥20% and saving over ¥300,000 in annual electricity costs. The system compensates DC bus voltage during grid fluctuations exceeding 15% to ensure stable operation.
• Lightweight and low-consumption drive: Incorporates Henan Mine’s new lightweight design, reducing equipment weight by 15%-30%. Combined with the YE4 ultra-high-efficiency energy-saving motor, overall energy consumption is reduced by 30% compared to traditional equipment. Transmission components feature hardened gear surface grinding for high transmission efficiency and minimal wear, reducing energy loss.
• Low-Maintenance Structure: Core components feature modular design with fewer wear parts and simplified replacement. Electrical systems meet IP54 protection standards, equipped with dehumidification and cooling devices for salt fog and dusty environments, reducing failure rates by 40%.
