[0002] The quay crane, also known as the shore container crane or bridge crane, is a device used to load and unload containers on ships at the shore. With the increase in the throughput of container operations at the Yangtze River inland terminal, the frequency of quay crane operations at the terminal has increased accordingly. During the loading and unloading process, the container truck must frequently move the operating position. How to quickly and reliably achieve one-time positioning has become a current problem. The working habits of the terminal operating container truck drivers are to shout on the intercom, look up, etc. to determine the size of the current operating box. The positioning is basically based on personal experience to select a reference point on the quay crane truck for alignment. Some even wait until the hoisting box is suspended on the upper part of the container truck flatbed and wait for the container truck driver to reverse and touch the box to place the box. After the box is placed, some container trucks start when the quay crane hoist is not unlocked and raised to a safe height in order to blindly pursue the operating speed, which often leads to the "pull-off" phenomenon of the container truck. At present, the container truck cannot be accurately placed on the bottom side of the container, and the personnel on the quay crane cannot observe whether the container is placed horizontally on the container truck, which makes it easy to tilt and cannot be transported.
