Truss crane mainly refers to truss gantry crane which use truss structure, welded from shaped-steel, divided into two working-level mid-level and light-level system according to the busy degree of use. Truss gantry crane is mainly used in factories, open area between fixed cross, construction and installation sites, lumber yards and other places, due to the wind size is smaller than the box-shaped structure. Truss crane is particularly suitable for large sandstorm place, generally for handling and lifting work.
