Top quality MG double girder truss structure crane

MG(A) type double girder truss structure crane with hook is applied outside warehouse or railway sideways to do common lifting and unloading works, this kind of crane is composed of bridge, support legs, crane traveling organ, trolley, electric equipment, strong lifting winch, the frame adopts truss-type welding mechanism, this result to small windward side. (The wind-pressure is less than 125Pa).crane traveling mechanisms are operated in the driver cabin or remote control.
