How is chain strength calculated?
Determining Chain Working Load Limits WLL = MBL / SF. Where MBL is the minimum breaking load and SF is the safety factor. A safety factor is the ratio between allowable stress and actual stress.

What is the working load limit of a chain?
The term Working Load Limit (WLL) refers to the maximum amount of tension that can be applied to a new and undamaged chain. It is a rated capacity and often referred to in pounds. Working Load Limit is calculated by dividing the minimum breaking strength of the chain by the assigned safety factor rating.
How much force is needed to break a chain?
As it turns out, the European ISO standard of 8,000 Newtons of minimum breaking force for a chain offers a good margin of security.
How do you calculate chain work load?
Working Load Limit is calculated by dividing the minimum breaking strength of the chain by the assigned safety factor rating. The grade and diameter of the chain is also used to determine the working load limit.
How do you calculate lifting chain capacity?
To calculate the SWL of lifting chain in kilograms, multiply the diameter (D) in millimetres (mm) squared, by the grade (G), by either 0.3 or 0.4. For Grade 80 chain, use 0.4, and for Grade 30 or 40 chain, use 0.3. For example: Chain diameter, 10 mm.
