Description

Technical Field

[0001] The utility model relates to the technical field of slings, and more specifically to a sling for a large-diameter heavy-load cable packaging tray. Background Art

[0002] Large diameter heavy-load cables usually use steel-wood hybrid cable packaging drums. The skeleton of the side plates on both sides of the steel-wood hybrid cable packaging drum is welded with steel sections, and the fan-shaped plates on the side plates and the diameter strips on the barrel are made of wood. The steel skeleton and the wood plate are fastened with bolts; the confluence center of the side plates on both sides is welded with a shaft sleeve of exactly the same size.

[0003] Existing large-diameter heavy-load cables are usually lifted with a hook and a whole steel wire rope. However, due to the large mass of the steel-wood hybrid cable packaging drum, the following problems exist during the lifting process: First, when lifting with a hook and a whole steel wire rope, the lifting device is prone to uneven force, and the entire packaging drum is skewed, causing the packaging drum to be damaged due to the huge impact load, and there is a risk of damage to the cable product and personal accident; Second, the steel wire rope of the lifting device passes through the shaft sleeve of the cable packaging drum. During lifting, the steel wire rope rubs against the edge of the shaft sleeve end, and the triangular lifting and the lower wide and upper narrow increase the bending stress of the two side plates of the packaging drum during lifting, causing the two side plates of the cable packaging drum to be easily damaged during lifting.
