Double Girder Gantry Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Heavy-duty material handling in shipyards, steel mills, construction sites, ports, large-scale logistics hubs, and outdoor industrial facilities requiring high-capacity lifting solutions.

Product Overview

Our Double Girder Gantry Crane is engineered for extreme load capacities and long-span operations, combining robust construction with advanced automation for demanding industrial environments. Designed with European-grade engineering principles, it delivers unmatched stability, precision, and durability for lifting capacities up to 500 tonnes and spans exceeding 50 meters. Ideal for outdoor heavy-lifting tasks, this crane minimizes downtime and maximizes productivity in harsh conditions.

Key Features & Benefits

Heavy-Duty Performance
- Reinforced double box girders (FEM 3m–5m class) ensure minimal deflection under full load.
- Optimized load distribution reduces stress on foundations and rail systems.
Advanced Automation & Safety
- PLC-controlled anti-sway and collision-avoidance systems for precise load positioning.
- Dual braking mechanisms, overload protection, and emergency power backup.
Durability in Harsh Environments
- Hot-dip galvanized or epoxy-coated steel structure (ISO 12944 C5-M corrosion resistance).
- IP66-rated motors and dust-proof electrical panels for extreme outdoor conditions.
Energy Efficiency
- Regenerative braking systems recover energy, reducing power consumption by 20–30%.
- Variable frequency drives (VFD) ensure smooth acceleration and deceleration.
Customizable Design
- Adjustable gantry legs for uneven terrain or rail-mounted configurations.
- Compatibility with specialized hooks, grabs, or lifting magnets.
