Truss Gantry Cranes: the "steel backbone" of bridge construction
At the bridge construction site, the Truss gantry crane stands tall like a red giant, supporting the core task of lifting precast beams with its ingenious truss structure design.
Technical Parameters:
| Lifting Capacity | 50～300 t (larger tonnage can be customized) |
| Span | 15～40 m (including cantilever extension) |
| Lifting Height | 10～30m (ground to top of hook) |
| Lifting Speed | Full load: 0.5～3m/min, no load: 1～6m/min |
| Work Duty | A 6～A 8 |
Truss strength, adaptable to the arduous task of infrastructure construction.
The truss, its "backbone," is a lattice system of members woven horizontally and vertically. Its lightweight structure boasts exceptional load-bearing capacity, easily supporting 100-ton precast beams. Its hollow structure offers low wind resistance, making it rock-solid even under open-air operations. It perfectly meets the demanding requirements of bridge construction: large spans, heavy loads, and multiple working conditions.
Precise operation, interconnected construction processes.
During lifting, it precisely grasps the precast beams like a "steel hand," steadily moving horizontally and vertically along the track, placing the massive beams precisely on the piers. From material lifting to beam erection, the entire process is efficiently integrated, transforming the "puzzle in the air" into standardized procedures.
Safety and efficiency, dual-enabling engineering.
The truss distributes load evenly, offering excellent torsional and wind resistance, providing a strong safety net for high-altitude operations. The modular truss also allows for rapid assembly, shortening construction preparation times. It uses the toughness of steel to accelerate the construction of bridges across natural barriers, and also bears witness to the construction wisdom of "making light of heavy things" in the infrastructure field.
