[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The lifting beam is a special crossbeam sling used in cranes to lift heavy objects. It is mainly used to lift goods that are long or have other irregular shapes, to ensure that the heavy objects do not tilt during the lifting process, and to ensure the stability and safety of the lifting.
