Chain slings stand at the center of every serious lift, yet no single grade rules every job. A maintenance shop loves rugged Grade 80; a wind-tower crew needs lean Grade 100; a salt mine sticks with ultra-hard D-grade links. This guide breaks down six Topone® product lines—Grade 100, Grade 80, Mining, DIN-standard, NACM-standard, and ASTM-standard—adds real numbers from lifting-chain.com, and maps each sling to its ideal market. Scan the data, spot your match, and buy once with total confidence. 

1 | Grade 100 Chain Slings

Core spec – 980 MPa yield, 1 180 MPa tensile, proof tested at 2.5 × WLL.

Why choose – lifts 20-25 % more than same-diameter G80, so crews drop one size and gain up to 200 mm headroom.

Typical build – 13 mm, four-leg adjustable chain sling with grab shorteners, self-locking hooks, and 130 × 70 mm master link.Best industries – OEM production lines, turbine halls, bridge-beam yards—anywhere cranes fight ceiling height or floor loading.

Finish set – black epoxy for indoor, hot-dip zinc for outdoor, red powder for color-coded rigging plans.

Add-on kits – clutch shorteners, “4 way chain rigging” equalizer rings, RFID tags for digital inspections.

2 | Grade 80 Chain Slings

Core spec – 640 MPa yield, 800 MPa tensile, 4 : 1 design factor, proof at 2.5 × WLL.

Why choose – price point meets rental budgets; 10 mm lifting chains pair with eye hooks for speedy hook-ups.

Popular builds – 3 leg chain sling for prefabricated concrete, 2 leg compact sling for steel fabricators.

Best industries – construction sites, general fabrication, municipal maintenance.

Finish set – black paint for dry yards, manganese phosphate for dusty quarries, hot-dip zinc for fleets that travel.

Accessories – wide-throat foundry hooks, “chain lifting hooks” with latch kit, link-by-link shortening claws.

3 | Mining Chain Slings (DIN 22252 D-Grade)

Core spec – 900 MPa tensile minimum, 350–390 HB hardness on fully hardened skin, 64 HRC optional for salt mines.

Why choose – round-link geometry sheds impact and digs through grit; spiral shackles bolt right onto scraper bars.

Common builds – double-leg chain sling dragging armored-face conveyor drives; single-leg compact sling swapping pump gearboxes.

Best equipment – beam-style loaders, plough shearers, longwall stage loaders.

Finish set – bare tempered steel for fire-hazard coal faces, electro-gal for potash brine, carburized skin for rock-salt gouge.

Upgrades – “heavy lifting slings” with cup-link connectors, side-plate shackles, spring clip spares.

4 | DIN-Standard Chain Slings

Standards covered – DIN 764, 766, 763, 5684, 5685, 5687/5688, 22252:2001.

Why choose – calibrated pitch drops directly into windlass drums, chain conveyors, and European crane blocks.

Product range – long-link DIN 763 for marine mooring; short-link DIN 766 for anchor windlass; mid-link 5684 for fish-processing conveyors.

Industries – shipbuilding, agriculture, sugar mills, sawmills.

Surface menu – hot-dip zinc for deck, copper-nickel overlay for fish brine, carburized skin for abrasive feed grain.

Options – “adjustable slings” with sliding clamps, bespoke odd-pitch sections for antique winches.

5 | NACM-Standard Chain Slings

Standards – NACM 96, 84/90, 2010; follows U.S. commercial tolerances.

Why choose – fits American hoists and chain block lifting equipment for sale with zero pocket re-machining.

Typical build – 20 ft lift lever hoist using 8 × 24 mm Grade 80 load chain and 5 mm hand chain.

Industries – HVAC riggers, stateside utility crews, trailer manufacturers needing “buy lifting chains” locally.

Finishes – mechanical zinc for transport tie-downs, black oxide for theater rigging.

6 | ASTM-Standard Chain Slings

Why choose – ASTM F1145, A973, plus coating specs assure chemistry and hardness to the decimal, ideal for refinery and nuclear documents.

Options – Grade 80 and 100 alloy, galvanized transport chain, decorative proof coil, “certified lifting straps” in stainless.

Industries – petrochemical, aerospace ground support, military depots.
