CALIBRATED LOAD CHAIN

CALIBRATED LOAD CHAIN

Used for - Chain Hoist and Lever Hoist

PROPERTIES
• Working Load Limited (W.L.L.) is the maximum load which chain or components are designed to sustain in lifting use. The mean stress at this load is 200n/mm2 (M.P.A.) and is based on a factor of safety of 4:1.
• Manufacturing Proof Force (M.P.F.) is the force to which during manufacture chain or components are subjected. The mean stress at this load is 500n/mm2 (MPA) which is 2.5 times the working load limit.
• Minimum Breaking Load (M.B.L.) is the minimum force which chain or components must withstand before failure. The mean stress at this load is 800n/mm2 (MPA). The minimum elongation before failure is 20%.
