Abstract

The invention provides a lifting sling for a steel coil bundling strap bag. The lifting sling for the steel coil bundling strap bag comprises a lifting sling body and a safety rod. An upper lifting ring is arranged at the upper end of the lifting sling body, and a lower lifting ring is arranged at the lower end of the lifting sling body. The inner diameter of the lower lifting ring is larger than the outer diameter of the safety rod. The length of the safety rod is larger than the inner diameter of the steel coil bundling strap bag. A steel wire rope which is used all the time in the prior art is replaced, and problems occurring when the steel wire rope is used for hoisting weights are solved. When the lifting sling is used, the lifting sling body is made to penetrate through a hollow cylinder of the bundling strap bag, then the safety rod is made to penetrate through the lower lifting ring, it is guaranteed that the two ends of the safety rod can both make contact with the lower bottom surface of the bundling strap bag, and lifting begins after a hook of a lifting device is connected with the upper lifting ring. The lifting sling is convenient and fast to use, capable of saving time and labor, high in safety performance, simple in structure, low in machining and manufacturing cost and easy to apply and popularize.
