Description

Technical Field

[0001] The utility model relates to the technical field of crane slings, in particular to a sling installation structure for a crane. Background Art

[0002] When the crane is directly hoisted using the sling, the gravity of the object being hoisted will directly act on the crane, which can easily reduce the service life of the crane.
