30t 40t 50t Rail Mounted Double Girder Container Gantry Crane Manufacturer

Rail Mounted Double Girder Container Gantry Crane consists of main girder, rigid and flexible door legs, running trolley, hoisting mechanism, long traveling mechanism, electrical system, operating cabin and so on.

According to the yard operation process, the cantilever is extended in the direction of the single door leg or the direction of the double door to become a single cantilever or double cantilever type and does not extend into a non-cantilever type.

1 The lifting speed is lower and the speed of long traveling is higher. According to the demand of the container yard, the lifting height of the rail-type container gantry crane is determined by the stack of three or four or four or five piles. Since the lifting height is not high, the lifting speed is correspondingly low. However, the container yard generally has a long length along the running track. In order to achieve certain productivity, the speed of the crane long traveling is relatively high.

2 The running speed of the trolley can be determined according to the span of the bridge and the overhanging distance between the two ends. When the span and the length of the boom are small, the trolley running speed and productivity requirements are relatively small. When the span is large and the length of the cantilever is also large, the running speed of the trolley can be increased accordingly to meet the productivity requirements.

3 When the span exceeds 40m, during the high-speed operation of the crane, the offset will occur due to the different running resistance of the legs on both sides. For this purpose, a synchronizing device is set to keep the running speed of the running mechanisms on both sides synchronized by the electric control system.
