What is the most important factor of G80 lifting chain ?

Every G80 chain we supply meets the 4:1 safety factor per EN 818-2. Each batch is proof-load tested at 2.5 × WLL before leaving the factory

G80 chain1
G80 lifting chains have a wide range of applications, covering lifting, construction, marine, logistics, mining, and many other fields. A common requirement across these diverse applications is "safety."
According to the EN818-2 standard, the working load of a G80 chain is one-quarter of its minimum breaking tensile force.
A safety factor of 4:1 is the core of the G80 chain.
All other specifications—breaking tensile force, stiffness, elongation, and fatigue life—are set around this safety baseline.
This 4:1 factor covers all the unexpected factors that might be encountered in the application scenarios you mentioned.
