Description: 
Lifting Chains & Components are proof load tested at 2.5 times the working load limits, with resultant permanent deformation within 1%, dynamic fatigue testing where batch samples of chain and components are dynamic fatigue tested at 1.5 times working load limit for 20,000 cycles. It also includes ultimate breaking load testing, batch samples of chain and components are break load tested in a static tensile testing machine to ultimate failure. The minimum ultimate force that is equal to the working load limit times the safety factor. Yoke Industrial Corporation supplies lifting and material handling industry.
