Wire Rope Spider Slings

A wire rope spider sling is a four-leg lifting device that, in design and technical specifications, meets the requirements of GOST 25573-82.

Compared with other sling types, a spider sling offers higher load capacity, as well as the ability to maintain balance when hitching a load and move it with maximum precision. The length and thickness of the working legs are selected based on the weight of the load being lifted or moved.

Sling components:

• a suspended detachable link attached to the crane equipment;
• four steel wire rope legs;
• lifting attachments for securing loads — hooks, snap hooks, clamps, or other options.

The four legs of the spider sling evenly bear the load (calculated per rope leg), maintaining the position of the load’s center of gravity. The rigging process proceeds without skewing, keeping the moved items safe.

The steel wire rope used to make the spider sling has high strength and resistance to mechanical and dynamic stress, as well as to abrasion. The simplicity of assembly and maintenance makes this type of rigging equipment widely used.
