GJM40.5吨集装箱龙门起重机出口蒙古

2025 年 11 月 28 日

The GJM40.5t container gantry crane successfully deployed in Mongolia not only resolved the cargo handling bottlenecks at a local inland container hub but also became a benchmark case for Belt and Road infrastructure cooperation due to its efficient, intelligent, and safe performance. Its technical innovations, such as low-temperature adaptability and multi-directional rotation, provide practical solutions for similar equipment operating under extreme climates and complex conditions, promoting the development of container cranes toward modularity and smart automation.

Container Gantry Crane Equipment Overview

The GJM40.5t container gantry crane is a heavy-duty handling machine custom-designed for an inland container hub in Mongolia. Container gantry crane has a rated lifting capacity of 40.5 tons (under spreader), a rail gauge of 37 meters, and a lifting height of 21 meters (supports five-high, six-over stacking). The container gantry crane is equipped with ISO-standard container spreaders compatible with 20-, 40-, and 45-foot containers. The whole machine is CE-certified, complies with GB/T 3811-2008 crane design standards, and has a design life of 20 years.

Container Gantry Crane Core Application Scenarios

Container Yard Operations

Task: Loading and unloading 40-foot heavy containers (up to 38 tons each)
Outcome: Full-variable frequency drive system (no-load 80 m/min, full-load 36 m/min) combined with hydraulic anti-sway devices increased single-container handling efficiency by 40% and reduced energy consumption by 18%.

Multimodal Transport Support

Task: Connect railway freight station and road transport (daily throughput 1,200 TEU)
Outcome: ±5° spreader rotation adapts to different trailer directions; trolley 270° rotation covers multiple tracks, increasing yard utilization by 35%.

Extreme Climate Adaptation

Task: Continuous operation in -30°C low-temperature environment
Outcome: Low-temperature grease and fully enclosed electrical cabinets reduced equipment failure rate to below 0.5%, 60% lower than conventional cranes.

Container Gantry Crane Technical Innovations

Intelligent Monitoring System

CMS system monitors 12 key parameters in real time, including hoist and trolley operations, supporting remote fault diagnostics.
Equipped with 3D laser anti-collision system; operational safety distance accuracy reaches ±10 cm.

Structural Optimization

Main girder constructed from Q345D high-strength welded box steel with a self-weight coefficient of only 1.15.
Flexible leg-to-girder hinge design (±15° self-adaptive tilt) accommodates complex foundation conditions.

Environmental and Energy-saving Features

Energy recovery system recaptures potential energy during lowering, saving 20% power.
Low-noise design (operating noise ≤75 dB) compliant with ISO 11202.

User Feedback and Benefits

Efficiency: Single-shift handling increased from 80 TEU/shift to 130 TEU/shift; handling cost reduced by 30%.
成本优化： Modular design reduced spare parts inventory by 60%, saving approximately RMB 280,000 annually on maintenance.
安全记录： Equipped with eight safety measures including wind anchoring and anti-overturn devices; zero accidents reported in three years of operation.
