Gantry crane
Truss Type Gantry Crane (Wind-Resistant Lattice Structure)
Product Overview
The Truss Type Gantry Crane (also known as Flower Rack Gantry Crane) is engineered with welded structural angle steel and tubular lattice sections instead of solid enclosed steel plates. This open truss construction minimizes wind resistance, significantly reduces crane deadweight, and delivers exceptional structural stability in windy open-air environments such as coastal yards, river ports, and high-altitude infrastructure projects.
Key Features & Advantages
- Superior Wind Resistance: The hollow lattice truss structure reduces wind drag by over 60% compared to traditional box girders, ensuring safe operation during high wind conditions.
- Lightweight & Low Wheel Load: Lower deadweight exerts minimal wheel pressure on ground tracks, cutting foundation construction and rail installation expenses.
- Modular Pin/Bolt Connection: Engineered for fast disassembly, easy transportation via standard shipping containers or flat racks, and swift reassembly at new project sites.
- High Rigidity-to-Weight Ratio: Delivers high structural stiffness and low vertical deflection under maximum rated capacity.
- Cost-Effective Outdoor Solution: Ideal for temporary construction sites and seasonal open-air freight yards requiring equipment relocation.
