Description
Truss Gantry Crane is a kind of gantry crane that adopts a truss structure as the main girder, the rigid or flexible legs on both sides, and the truss main girder on the top form a gantry frame, which can be moved along the ground track to carry out lifting operations. The truss structure has about 40%-60% air permeability, the wind resistance coefficient is significantly lower than the traditional box girder gantry crane, especially suitable for ports, coastal areas, and other windy places.
The truss structure is usually connected by standardized rods and nodes, which is convenient for factory prefabrication and on-site assembly, easy for inspection and maintenance, and is suitable for engineering occasions requiring frequent disassembling and transferring, such as hydroelectric power station construction, bridge construction, and so on. It is widely used in harbor terminals, bridge construction, power station construction, heavy equipment manufacturing, and other fields.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Superior Wind Resistance
The open truss structure achieves 40–60% air permeability, significantly reducing wind drag and maintaining stability even in strong coastal or outdoor winds—a critical advantage over traditional box-girder designs.
Lightweight & Cost-Effective
The triangular lattice design offers high strength with reduced deadweight, lowering foundation investment, wheel pressure, and rail costs compared to box-girder alternatives.
Large-Span Capability
Structural optimization enables economical spans up to 60 meters, providing wide coverage for outdoor yards, ports, and construction sites without excessive weight.
Modular & Transportable Design
Standardized rod-and-node connections allow factory prefabrication, rapid on-site assembly, easy disassembly, and convenient transport—ideal for temporary or relocating project sites.
