Is a bridge crane deformation, also known as gantry crane.Mainly used for outdoor yard, yard cargo, bulk cargo handling operations.Electric hoist gantry crane has the characteristics of high site utilization, wide range of operation, wide adaptability, strong versatility, etc.Its metal structure is like a portal frame, bearing the main beam under the installation of two legs, can be directly on the ground on the track, the main beam at both ends can have an overhanging cantilever beam.
Operating environment of electric hoist gantry crane:
Generally applicable to - 10 ℃ to + 50 ℃, environment temperature, under the temperature of 40 ℃ relative humidity of not more than 50, the lifting of the molten metal forging hook, hook the radiation temperature does not exceed 300 ℃.Work level: A7, A8 for relatively busy metallurgical foundry workshop.
Electric hoist gantry crane structure introduction:
Electric hoist portal crane girder at both ends of the longitudinal seam welding, the girder has four longitudinal seam, welding sequence by the camber and side bending of the beam.In the case of insufficient cambidity, the left and right longitudinal seams of the lower cover plate shall be welded first. In automatic welding, the straight welding can be started from the end, while in manual welding, the welding shall be symmetrical from the middle to both sides.If the arch is too large, the two longitudinal seams of the upper cover shall be welded first. If the side bend is too large, the outer seam shall be welded first; if the side bend is too large, the inner seam shall be welded first.The electric hoist gantry crane has novel structure, beautiful shape, good technology, flexible and stable operation, safe and reliable.
