Structure of Double Girder Gantry Crane
Gantry cranes are Q345B steel material for steel structure and use legs to support the bridge, trolley, and hoist. They can travel on single or double rails on the ground. Widely used for indoors
and outdoor service, gantry cranes have strong box design, less distortion and automatic welding. The crane is composed with main beams, end beams, cantilever, front and rear legs, outrigger,
