[0002] Lifting rigging is the connecting part between the crane or the main body of the hoist and the hoisted object. It is also a general term covering slings and slings. There are two main types of rigging: metal rigging and synthetic fiber rigging.

During the lifting process, since the first stainless steel lifting ring and the second stainless steel lifting ring can rotate around the hanging rod as a whole, and the first stainless steel sleeve ring, the second stainless steel sleeve ring, the third stainless steel sleeve ring and the fourth stainless steel sleeve ring are respectively located on different semicircular rings of the first stainless steel lifting ring and the second stainless steel lifting ring, and due to the presence of the second fixed connection part, the first stainless steel sleeve ring, the second stainless steel sleeve ring, the third stainless steel sleeve ring and the fourth stainless steel sleeve ring cannot slide to other semicircular rings, and can only slide on the semicircular rings where they are located, so that the steel wire ropes can be prevented from being entangled with each other.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed lifting rigging has the following problems: in the prior art, although entanglement during lifting is avoided through the cooperation of components such as semi-circular rings, in actual use, due to the uncertainty of the size of the lifting object, the four sets of connecting rigging at the bottom are relatively rigid during use. If a smaller object is used, the gap may be larger and unstable. In view of this, a length-adjustable automobile lifting rigging is provided to overcome the above-mentioned defects.
