Chain spider sling

The chain spider sling (4STs) is a four-leg rigging device for handling heavy loads in demanding conditions.

The chain legs are attached in pairs to each connecting link. The design resembles a spider in appearance, hence the name. Slinging loads with a spider sling is reliable and provides a high level of safety.

Structurally, the device consists of:

• a load-bearing element with two connecting links, which is attached to the crane hook;
• four chains made of high-quality steel with a property class above 8;
• lifting attachments (hooks, rings, forks, snap hooks) — the choice depends on the type and mass of the load being moved.

The technical characteristics of 4STs slings allow them to be used at high temperatures and even in the presence of open flame — in metallurgical and pipe-rolling shops, and in machine building. Chain spider slings are also used for rigging work in logistics and warehousing, in agriculture, in large-scale construction, and for equipping crane machinery in sea and river ports.
