[0002] After the fishing boat returns from the sea, its catch will be packed separately in boxes. After the fishing boat arrives at the dock, the boxes containing the catch need to be carried to the dock one by one. Due to the height difference between the fishing boat and the dock, manual transportation one by one is too inefficient, so a sprocket-type circulating lifting device is generally used to unload the catch from the fishing boat to the dock.
