[0002] The cross-type quay crane is a new type of high-efficiency quay crane. The upper trolley can pass through the frame of the lower trolley. The two trolleys run at the same time, which can greatly improve the container loading and unloading efficiency of the port terminal. However, the energy consumption of the cross-type quay crane is higher than that of the traditional single-trolley quay crane. In order to reduce the operating cost of the cross-type quay crane and control the energy consumption of the cross-type quay crane, it is necessary to optimize the structure of the cross-type quay crane.
