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:
Lightweight design
adopting a space truss structure, lightweight, low foundation bearing requirement, suitable for large span operation.
Excellent wind resistance
the open truss structure has low wind resistance, strong wind permeability, and good stability, which is especially suitable for open-air environments, such as harbors and wind power installation operations. The stability is better than box crane in high wind speed areas.
Strong large-span capability
the truss structure can realize a large span (4 to 39 meters) by optimizing the grid layout, which is suitable for bridge construction, power station construction, and other scenarios.
Modular assembly
Segmented truss units, connected by bolts or pins, are easy to transport and quickly assembled on site. Suitable for temporary works or frequent moving operations.
