Double-girder Truss Gantry Crane: the "steel backbone" of heavy industry and the king of lifting

Whether in the steel coil yards of steel mills, container terminals at ports, or alongside the massive beams of bridge prefabrication yards, "large spans, high load-bearing capacity, and wind-resistant stability" are the core requirements for heavy lifting. The twin-girder truss gantry crane, with its "truss structure breaks through the constraints of deadweight and dual-girder design enhances load-bearing capacity," creates an efficient, safe, and durable heavy lifting hub for heavy industrial applications.

Structural Revolution: Hollow Truss × Double Girder Synergy
Integrated Material Intelligence: The main truss is constructed of Q460 low-alloy high-strength steel. A "spatial force network" is created through a CNC intersecting wire cutting and bolt welding process. Compared to box-type gantry cranes, this crane boasts a 35% reduction in deadweight while stably carrying loads ranging from 50t to 500t (customization is available to cover loads exceeding 1,000t).
Wind Drag Resistant: The hollow truss design reduces the wind drag coefficient by 30%, enabling safe operation in wind conditions up to force 8, making it suitable for open-air storage yards (such as ports and steel plants) regardless of wind or rain.
Dual Girder Efficiency Enhancement: The symmetrical dual main girders evenly distribute wheel loads (≤200kN), reducing rail wear by 60%, and enabling 24/7 continuous operation. Lifting 1,000 tons per day is no longer a myth for steel companies.
