Chain Parameter
SCIC Grade 70 (G70) transport chains cargo lashing are made as per AS/NZS 4344 standards. Chain links are well designed / monitored welding & heat-treatment ensure chains mechanical properties including lashing capacity, proof force, breaking force, elongation & hardness. Full inspection and tests are applied on chain batch.
G70 Transport Chains have the advantages of cleanliness, lightweight, strength and reliability and thus are ideal for tie-down applications for cargo securing with the transport and shipping industries.
We can supply chains with grab hooks and other components, per clients lengths.
Figure 1: Grade 70 chain link dimensions
Note:
dm = mean diameter of the material in the chain link
dn = nominal diameter of the material from which the chain is made
dw = diameter of the material at the weld
e = extent of the material affected dimensionally on either side of the weld
p = inside length
w1 = inside width
w = outside width
(w1, w excludes weld protrusion)
