Pioneers in bridge construction: Truss Gantry Cranes play a key role in infrastructure construction

In the vast expanse of the bridge construction site, the red Truss gantry crane stands tall like a steel giant. With the mechanical wisdom of its truss structure, it carries out the core mission of erecting precast beams, becoming the key engine for "crossing mountains and rivers" in the infrastructure landscape.

The Truss gantry crane's main beam and outriggers are constructed from triangular lattice trusses. The interlaced structure reduces loads into axial forces, achieving both lightweight and high-load-bearing capabilities:

Technical Parameters:

Sharply Reduced Weight: 30% lighter than a box-type structure, reducing foundation load.

Heavy-Load Control: A single unit can lift precast beams weighing 80-200 tons, with spans ranging from 15-40 meters, and is compatible with various beam types, including box beams and T-beams.

Wind Resistance: The hollow truss structure offers a low wind resistance coefficient, increasing wind resistance by 40% during open-air operations, ensuring rock-solid stability even in strong gusts.

Infrastructure Adaptation: A Full-Cycle Efficiency Engine
The value of the Truss gantry crane permeates the entire bridge construction process:
During the prefabrication phase, it serves as a "transportation hub," efficiently transferring formwork, rebar, and finished beams, reducing beam production cycles by 20%.
During the erection phase, it collaborates with the bridge crane to position beams, accelerating the completion of bridges and tunnels and transforming natural barriers into thoroughfares with greater efficiency.
During the operation and maintenance phase, its pin-jointed members increase assembly and disassembly efficiency by 50%, making it easy to adapt to project relocations and site expansions.
