Double-girder container gantry cranes | High-efficiency loading and unloading, stable and reliable, empowering ports and logistics hubs

In container ports, logistics parks, and railway freight yards, efficient container loading and unloading is crucial for ensuring smooth supply chains. Our double-girder container gantry cranes, designed with cable reel power supply, an integrated control room, and a safety ladder system at their core, provide a highly efficient, safe, and reliable solution for heavy-duty container transshipment.

Technical Parameters:

⚡ Stable Power Supply: Cable Reel, Unaffected by Long-Distance Operations
Utilizing a cable reel power supply system, replacing traditional cable chains or sliding wires, the system automatically retracts and extends the cable during trolley movement, ensuring stable and reliable power transmission. Whether in yards spanning tens of meters or in frequent loading and unloading operations, uninterrupted power supply is achieved, avoiding operational stoppages due to power outages and significantly improving the equipment's continuous operation capability.

🎛️ Intelligent Control: Integrated Control Room, One Person in Control
Equipped with an independent integrated control room, offering a wide field of vision and comfortable operation. The control room integrates a PLC control system, video monitoring, and a fault diagnosis interface, allowing operators to precisely control the entire process, including lifting, trolley movement, and gantry movement. Supports remote monitoring and data transmission, seamlessly integrating with the port's TOS system for automated scheduling and operational optimization.

🛡️ Safety First: Full-process protection safeguards every operation.

Safety Ladder System: Anti-slip ladders and guardrails are installed on the main beam and outriggers, facilitating safe access for maintenance personnel to all inspection points, meeting industrial safety standards.

Multiple Safety Protections: Equipped with lifting limit switches, travel limit switches, overload protection, windproof anchoring devices, and an audible and visual alarm system, effectively preventing risks such as collisions and overturning.

Structural Strength Guarantee: The double-beam portal structure is welded from high-strength steel and has undergone rigorous stress testing and fatigue analysis, capable of withstanding heavy-duty operations under harsh conditions.

⚙️ High Efficiency: Tailor-made for container transshipment.

Large Span and High Lifting Capacity: Standard span 18–40 meters (customizable), lifting height up to 15 meters or more, meeting the needs of multi-row container stacking and loading/unloading.

Precise Positioning: Utilizing a variable frequency speed control and positioning system, container positioning error is controlled within ±10mm, significantly improving loading and unloading efficiency.

Flexible Adaptability: Supports standard containers such as 20ft, 40ft, and 45ft, and can be equipped with spreader rotation and tilting functions to adapt to different loading and unloading scenarios.

Low Maintenance Costs: Key components adopt a modular design, making it easy to replace vulnerable parts. The long maintenance cycle of the entire machine results in more economical long-term operation.

🌐 Applicable Scenarios:

Container Ports: Container stacking and ship loading/unloading operations in terminal yards, improving port throughput capacity.

Railway Freight Yards: Loading, unloading, and transshipment of dedicated railway container trains, achieving seamless sea-rail intermodal transport.

Logistics Parks: Container storage and scheduling in large logistics centers, optimizing warehouse space utilization.

Industrial Manufacturing: Transshipment of heavy equipment and modular components in large factories, adapting to intelligent manufacturing production lines.
