Steel lifting chain G80

steel alloyalloypowder-coated steel

Description
G80 load chain designed for trawl and marine lifting applications. Manufactured from alloy steel (20Mn2 / 20Mnv) and produced to referenced industrial standards, this chain series provides defined working load limits and certified test/breaking loads for selection in deck and lifting equipment.

Applications

• Deck trawl gear and fishing winches
• Chain pulley blocks, lever pulleys and electric hoists on vessels
• Marine lifting slings, crane and industrial lifting operations where trawl-specific chains are required

Materials & Standards

• Material: Alloy steel 20Mn2, 20Mnv
• Referenced standards: ISO 3077, EN 818, AS 2321
• Safety assurance: 4× safety factor; tested loading capacity 2.5× working load

Detail Items

• Grade: G80 (high-tensile alloy load chain), also available in Grade 70 and Grade 60
• Surface treatment: Natural/unchanged, oxide black, shot blast, painted, electro-galvanized, hot-dip galvanized, powder coated
• Typical uses: Chain pulley, lever pulley, electric hoist, crane, binding and lifting slings
• Rupture/breaking capacity: Specified by grade and diameter (refer to dimensional/load tables)

Parameters
G80 load chain available in multiple nominal diameters and pitches. Chains are offered in finishes suitable for marine environments and can be selected according to working load limit (WLL), proof load and minimum breaking load values provided in the technical tables.
