What is the main girder of the gantry crane?
Single gantry gantry crane structure is simple, easy to manufacture and install, its own quality is small, the main beam for the partial rail box frame structure.
Compared with the double girder gantry crane, the overall stiffness is weaker.Therefore, when the weight Q ≤ 50t, span S ≤ 35m, can be used in this form.
L-type manufacturing easy installation, the force is good, their own quality is small, but the lifting of goods through the legs at the relatively small space.
C-shaped feet made of inclined or curved, the purpose is to have a larger horizontal space, so that the goods successfully through the feet.
