Published on: Oct  20, 2025 | Source: chen | Hits: 0

A single chain sling, also known as a single leg chain or single leg chain sling, is one of the simplest yet most effective lifting tools in the rigging industry. Built with a master link, a single chain leg, and a hook at the end, this sling is ideal for vertical lifting tasks where stability and precision are required.

This article explores the features, applications, working load limits, and safety considerations of single chain slings. It also explains why TOPONE CHAIN® single leg slings are trusted worldwide for certified and reliable lifting operations.


What Is a Single Chain Sling?

A single leg chain sling consists of:

Master link: Connects the sling to a crane or hoist.

One chain leg: Made from quenched and tempered G80 or G100 alloy steel.

Hook or fitting: Typically a grab hook, self-locking hook, or foundry hook.

Safety Tips for Single Chain Sling Use

Always match the sling’s WLL to the load.

Use edge protectors if lifting sharp-edged items.

Inspect chain and hook for cracks or elongation before use.

Never exceed the rated capacity.

Retire the sling if any damage exceeds safe limits.
