Selecting the right chain sling is critical for safe and efficient lifting. With multiple configurations, chain grades, and end-fitting options available, the choice depends on more than just Working Load Limit (WLL). You must also consider load shape, environment, lifting method, and sling angle.
This guide explains the key decision factors and provides a practical framework to help you choose the correct sling for your application — based on international lifting standards and TOPONE CHAIN® manufacturing expertise.

Identify the Load Type

Different loads require different sling configurations.

Determine the Required Chain Grade

The chain grade determines lifting capacity and safety margin.

If the lifting environment demands higher WLL with smaller chain diameter, G100 or G120 is the better choice.

Consider the Working Environment

Not all chain slings are suitable for all environments.

Choose the Right Hook Type

The hook defines how the sling connects to the load.

Pay Attention to Sling Angle

Even the strongest sling loses capacity when used at a wide angle.
A 60° sling angle has SIGNIFICANTLY lower WLL than a 30° angle.

Rule of thumb:

The greater the angle, the lower the safe working load.

This is why choosing the right configuration is not just about weight, but geometry.

Certification & Traceability

A safe chain sling must meet global safety standards such as:

EN 818

ISO 3077 / ISO 7593

TÜV / CE certification

NACM standards (North America)

Full traceability (batch number or laser code) ensures quality and legal conformity.

Example Selection Scenario

Scenario:
Lifting a steel beam weighing 6 tonnes in a construction yard.

Correct chain sling:

Two-leg sling (because there are two lifting points)

G100 grade (for higher WLL margin)

Self-locking hooks (to prevent unintentional release)

30–45° sling angle (to maintain optimal load capacity)

Conclusion

Choosing the right chain sling is not a one-step decision. It requires understanding:

Load characteristics

Chain grade and configuration

Environmental conditions

Angle factors

Certified safety markings

By applying these criteria, rigging teams can ensure safe, efficient, and compliant lifting.
