Container Gantry Crane

Rail mounted double girder container gantry cranes are mainly used for container handling, handling and stacking of container railway transfer yards and large container storage yards.

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.

Rail Mounted Double Girder Container Gantry Cranes have the following main features:

• 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 a certain productivity, the speed of the crane long traveling is relatively high.
• 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.
