[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. It is also called an overhead crane, overhead crane, or crane. A bridge crane is a lifting equipment that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal supports, it is shaped like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides. It can make full use of the space under the bridge to lift materials without being hindered by ground equipment and is widely used.

[0003] The most commonly used lifting component of existing bridge cranes when in use is the hook, which is used in conjunction with the cable to directly lift objects.
