GJM40.5t Double Girder Gantry Crane with Two Hoists Exported to Mongolia

The GJM40.5t double girder gantry crane with two hoists 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.

Double Girder Gantry Crane with Two Hoists Equipment Overview

The GJM40.5t double girder gantry crane with two hoists is a heavy-duty handling machine custom-designed for an inland container hub in Mongolia. Double girder gantry crane with two hoists 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 double girder gantry crane with two hoists 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.

Double Girder Gantry Crane with Two Hoists Core Application Scenarios

Container Yard Operations

• Задача: Loading and unloading 40-foot heavy containers (up to 38 tons each)
• Вынік: 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

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

Extreme Climate Adaptation

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

Double Girder Gantry Crane with Two Hoists 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.

Водгукі карыстальнікаў і перавагі

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