Both the gantry crane and the mobile mold pallet are supported by running wheels on the track on the ground. During use, the mold pallet and the gantry crane may cross each other, resulting in poor stability and passability of the gantry crane and the mobile mold pallet when passing through the intersection of the tracks (when driving from one direction across the intersection, it is necessary to cross the track in the other direction, which will cause shaking and increased resistance). In addition, in order to prevent cross collisions by passing through the intersections one by one through manual on-site control and command, manual command wastes manpower and has a poor degree of automation.
