Gantry crane consists of large and small vehicle operating mechanisms, hoisting mechanisms, electrical systems, safety devices and cabs. The gantry crane is modified on the basis of a bridge crane with one or two legs at both ends of the main beam that can be run along a dedicated track on the ground. The main components are composed of main beam, end beam, lower beam, and legs. Common main beams are box beams, truss beams, and the like. Among them, the truss beam is made by welding steel pipe, and the box beam is made by welding plate. The end beams are respectively installed at the two ends of the main beam, and are composed of a plate beam, a truss and wheels to support the main beam.
1. The metal structure of the gantry crane is like a door-shaped frame. Two legs are installed under the main beam, which can walk directly on the track on the ground. These is a cantilever beam at the end of each beam.
2, The lifting weight of each single hook can reach 600t, which has a good improvement on the lifting height, and the strength is more obvious.
3, The site utilization rate is high, the scope of operation is large, the adaptability is wide, and the versatility is strong. It is widely used in port yards.
4. From the related technology of the equipment, this 600t crane uses a three-in-one rotating system. The whole equipment is controlled by the non-contact module of the electric appliance. The actual speed can realize the change of dangerous speed and two-speed operation . The most important thing is to have a multi-functional protection system on the operating platform when operating.
