[0002] A bridge crane is a type of lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal supports, its shape is like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides. The space under the bridge can be fully utilized to lift materials without being hindered by ground equipment. It is the most widely used and largest number of lifting machinery.

[0003] The existing anti-sway equipment of bridge cranes with adjustment function usually needs to lift the load to a certain height and then move it horizontally. Due to the influence of inertia, when starting or ending horizontal movement, the hoist will shake due to inertia, and this shaking will cause wear of the wire rope.

[0004] The existing patent (publication number: CN216038248U) is a bridge crane sling anti-sway structure, which performs the first buffering by squeezing multiple buffer rollers through steel wire ropes. The buffer rollers are subjected to force to push multiple buffer rods outward. Multiple torsion springs and second springs perform a second multi-directional force buffering on the buffer rods. The buffer rods are subjected to force on the second buffer shell. The first springs on both sides perform a third force buffering on the second buffer shell, that is, multiple buffering can be performed on the sling, which can effectively prevent the sling from shaking.
