When loading and unloading cargo from the top, the top cover needs to be removed from the hard open top box first. When the cargo is loaded and unloaded, the top cover can be repositioned to the top of the box to close the hard open top box. Typically, a locking device for securing the top cover is also provided on the hard open top box. When the locking device is in the snoring state, the top cover can be removed; when the locking device is in the locked state, the top cover is fixed relative to the side plates, thereby ensuring the safety of the goods in the box. Usually the customs seal will also be placed on the locking device.

A locking device is now known which includes a plurality of buckles disposed at the top side rails of the hard open top box. When it is necessary to remove or secure the top cover, it is necessary to manually open or close the buckle. However, hard open top boxes typically have a higher height, so that in order to close the buckle it is necessary for the worker to reach the top of the box through the ladder or platform. If there is no height suitable for climbing ladders or platforms at the operation site, the top cover opening and closing operation and the assembly and disassembly seals cannot be smoothly performed.
