Slings get used to lift loads by either wrapping around the load and connecting to the crane’s chains, or attaching to shackles and lifting points on the load.

Slings come in various lengths to give versatility, depending on how big the load is. They’re also colour coded. Each colour represents the sling’s Working Load Limit (WLL), which is the maximum weight of the load that the slings are permitted to lift. The amount of stripes that are stitched into the slings also represented this.

The WLL can change depending on how the load gets slung. For example, choking the slings on themselves reduce the lifting capacity, as well as what angle the slings are at when lifting. This is determined by mode factors.

Here is an example of a load chart. It gives a guide to mode factors.

Slings usually have labels that show some mode factors as a guide

All slings should be checked for damage before using. Any tears or fraying should be reported. The sling will probably get discarded.

If a load is to be wrapped, most sites require you to double wrap every time. Although, there are some circumstances where they don’t need to be double wrapped. Like, if the load is banded or ratchet strapped.

Slings should be stored off the ground, either in a chain box or chain rack, to keep the clean and out of standing water.

There are two types of slings. Web slings and endless slings.

Slings Guide

Web Slings

Web slings are flat with loops at either end.

---

Endless Slings

Endless slings are more rounded in shape. They’re continuous, so have no ends. Hence, the name.
