Material

Molding, no welds, high-precision cold-

formed molding, eliminating the traditional production grinding, cutting, welding,

and many other complicated production process, reduce to the deformation of the

single beam crane girder in the handling process, to ensure that a single beam

crane girder precision. Improve the work efficiency, while greatly enhanced the

whole strength, and improve the quality of cranes appearance.
