They are indispensable key components in lifting operations and are directly related to the safety and efficiency of the operation.

[0003] A search revealed existing slings, such as the one disclosed in CN111891897B, which has a detachable sheath. This sling consists of a lifting column, a first double-ended bolt, protrusions, a first sling, and a sling. Tightening the first double-ended bolt fixes the lifting column between the protrusions. At this point, the first sling connects the lifting column and the sling. The four first slings are evenly distributed, resulting in balanced force on the sling and enhanced stability. However, after lifting the material, the angle of the material needs to be adjusted according to different requirements. Existing slings cannot adjust the angle of the material and require other equipment for adjustment, which is inconvenient. Therefore, a sling with a detachable sheath is proposed.
