Gantry crane
U-Type Double Girder Gantry Crane
Product Overview
The U-Type Double Girder Gantry Crane features an innovative “U”-shaped arched leg configuration that eliminates the lower crossbeam interference common in standard A-frame cranes. This specialized structural geometry provides massive horizontal clearance between the legs, allowing bulky cargo, 20ft/40ft standard containers, and long precast concrete components to pass through seamlessly without turning or tilting.
Key Features & Advantages
- Obstruction-Free Leg Passage: U-shape arch structural design allows wide, long materials to move smoothly from the span area to the cantilever zones.
- Lower Overall Profile: Reduced overall crane height compared to conventional high-leg A-frames, resulting in a lower center of gravity and reduced wind load.
- High Operational Efficiency: Optimized for intermodal logistics and precast component handling, drastically shortening loading and unloading cycle times.
- Reduced Civil Runway Cost: Balanced wheel pressure distribution reduces dynamic runway impacts and minimizes ground foundation preparation costs.
- Multiple Spreader Configurations: Supports semi-automatic or fully automatic container spreaders, rotating hook blocks, C-hooks for steel coils, and customized spreader beams.
