Product Overview<\/p>\n

EN 818-2 Grade 80 Chain for Lifting Applications<\/h2>\n

Grade 80 lifting chains are alloy steel short-link chains manufactured to EN 818-2<\/strong>, designed for assembly into chain slings and for use with cranes, hoists, and industrial lifting equipment. The grade designation indicates a minimum tensile strength of 800 N\/mm\u00b2, achieved through precision flash butt welding and quench-temper heat treatment of 20mm2 25mnv alloy steel<\/strong>.<\/p>\n

Ever-power Engineer Class Chain Co., Ltd produces G80 chain in diameters from 6 to 48 mm<\/strong>, covering working load limits from 1.1 t (6 mm) to 72.5 t (48 mm). All chains are proof tested at 2.5\u00d7 working load limit<\/strong> and carry a minimum breaking load of 4\u00d7 working load limit<\/strong> (4:1 safety factor). Each link is permanently embossed with the G80 grade mark<\/strong> for identification and in-service inspection.<\/p>\n

Surface treatments include hot-dip galvanising, electro-galvanising, blackening, electroplating, and powder coating, selected to suit the operating environment. Wire rope clamps, connecting links, and sling hardware are available to complement the chain supply.<\/p>\n<\/div>\n

Construction & Standards<\/p>\n

Product Features<\/h2>\n
\n
\n

Standard: EN 818-2<\/h3>\n

Manufactured to EN 818-2 (medium tolerance short link chain for lifting purposes \u2014 Grade 8). This standard defines dimensional tolerances, mechanical property requirements, and the proof testing procedure applicable to Grade 80 lifting chains.<\/p>\n<\/div>\n

\n

Material: 20mm2 25mnv Alloy Steel<\/h3>\n

Links are manufactured from 20mm2 or 25mnv alloy steel, precision flash butt welded and quench-tempered to achieve the Grade 80 minimum tensile strength of 800 N\/mm\u00b2 and the required ductility for overhead lifting service.<\/p>\n<\/div>\n

\n

4:1 Safety Factor<\/h3>\n

Minimum breaking load is not less than 4\u00d7 the working load limit across all sizes. Proof load testing at 2.5\u00d7 WLL is carried out on every chain before dispatch. Working load limits range from 11 kN (6 mm) to 725 kN (48 mm).<\/p>\n<\/div>\n

\n

G80 Link Marking<\/h3>\n

Each link is permanently embossed with the G80 grade designation and manufacturer code at regular intervals along the chain. This allows grade identification and traceability during in-service inspection without removal from the sling assembly.<\/p>\n<\/div>\n

\n

Size Range: 6 to 48 mm<\/h3>\n

Twenty standard sizes from 6\u00d718 to 48\u00d7144 mm cover the full range of chain sling and hoist chain applications, from light-duty rigging to heavy industrial and port crane service. Accessories including wire rope clamps and connecting links are available.<\/p>\n<\/div>\n

\n

Surface Treatment Options<\/h3>\n

Available with hot-dip galvanising, electro-galvanising, blackening, electroplating, or powder coating. Treatment selection is based on the humidity, salt, and corrosive exposure expected in the operating environment.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

FAQ<\/p>\n

Frequently Asked Questions<\/h2>\n
\n

What does Grade 80 mean?<\/h3>\n

Grade 80, also written G80 or Grade 8, indicates a minimum tensile strength of 800 N\/mm\u00b2 for the chain material after heat treatment. The grade number is used to define the working load limit and minimum breaking load for a given chain diameter.<\/p>\n<\/div>\n

\n

What is the difference between EN 818-2 and EN 818-7?<\/h3>\n

EN 818-2 specifies medium tolerance short link chain intended for assembly into lifting slings. EN 818-7 specifies fine tolerance chain designed for use in chain hoists and blocks, where calibrated pitch dimensions are required for correct engagement with the hoist pocket wheel. The G80 chain in this listing is EN 818-2 (medium tolerance) and is intended for sling assembly and general lifting use.<\/p>\n<\/div>\n

\n

What is the working load limit for 16 mm Grade 80 chain?<\/h3>\n

The working load limit for 16\u00d748 mm Grade 80 chain is 80 kN. The proof load is 192 kN and the minimum breaking load is 320 kN, giving a 4:1 safety factor relative to the WLL.<\/p>\n<\/div>\n

\n

Are chains proof tested before dispatch?<\/h3>\n

Yes. All Grade 80 chains are proof load tested at 2.5\u00d7 the working load limit as part of the standard production QC process. Test certificates are available on request.<\/p>\n<\/div>\n

\n

What surface treatments are available?<\/h3>\n

Standard options are hot-dip galvanising, electro-galvanising, blackening, electroplating, and powder coating. Treatment selection depends on the operating environment \u2014 galvanising is typically specified for outdoor or marine-adjacent applications.<\/p>\n<\/div>\n

\n

Can Ever-power supply sling hardware to match the chain?<\/h3>\n

Yes. Wire rope clamps, connecting links, hooks, shackles, and load binders compatible with Grade 80 chain are available. Please specify the chain diameter and intended sling configuration when enquiring.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Grade 80 lifting chains are used alongside a range of drive and transmission chains in industrial facilities. Those specifying chain for material handling systems may also find reference in power transmission chain standards<\/a> for conveyor and drive applications, and in industrial roller chain specifications<\/a> for ancillary plant drives. For wider chain product reference including bulk supply and engineering data, heavy-duty chain engineering resources<\/a> and sprocket and chain drive system guidance<\/a> provide useful complementary context.<\/p>\n<\/div>\n<\/section>\n
