Precision-forged leg chain sling systems built for India's toughest lifting and rigging operations.

RUD India offers chain slings in five leg configurations, each suited to a specific lifting task.
1 Leg Chain Sling: A single chain with a master link and hook, used for straight vertical lifts or as a choker hitch around pipes and round stock.
2 Leg Chain Sling: Two legs from a common master link, matched to loads with two defined lifting points, such as eye bolts or lugs on either side.
3 Leg Chain Sling: Three legs spread from the master link, built for loads with uneven weight distribution, including irregular castings and fabricated brackets.
Four Leg Chain Sling: Four legs from a common master link, used on wide or box-shaped loads like precast panels and equipment skids. Rigging practice treats one leg as a safety margin, since load-sharing across four points is rarely perfectly even.
Endless Chain Sling: A continuous loop with no fixed end fittings, rigged as a choker or basket hitch around drums, coils, beams and stock with no built-in lifting point.
The right chain sling configuration comes down to how many lifting points the load has, how its weight is distributed and how much headroom is available above it.
Start with the load's lifting points. A single eye or round profile suited to a choker hitch calls for a 1 leg chain sling. Two aligned lugs point to a 2 leg sling. Three or four points, common on machine bases, tanks and fabricated frames, call for a 3 or 4 leg sling.
Symmetry matters as much as the point count. The multi-leg factors in the chart below apply to symmetrical loading only, where the weight spreads evenly across all lifting points. A load that does not meet that condition falls outside the chart, so a qualified rigger should assess it before the lift.
Headroom and rigging angle affect capacity directly. A steep leg angle close to vertical gives higher WLL than a wide, shallow angle, so confirm available crane height before fixing the leg length.
2 leg chain sling capacity is not a single fixed number. It depends on three variables: the chain grade (Grade 80 or Grade 100 VIP), the nominal chain diameter, and the angle each leg makes with the vertical during the lift.
As the leg angle widens from 0° to 45° and then to 60°, the working load limit drops, because each leg carries a larger share of the load's horizontal component. RUD calculates and certifies these values to EN 818-4 and DIN 5688, the standards governing chain sling design and testing.
A 10mm Grade 80 chain, for instance, rated near 3.15 tonnes on a single vertical leg, carries a different WLL again once used as a 2 leg sling at 45° to 60°. The full capacity chart below sets out these figures by diameter, grade and angle.
RUD chain slings are built from forged alloy steel, heat treated and calibrated to hold tight link tolerances, which keeps wear even across the chain length instead of concentrating stress at a few links. Each sling carries a RUD-ID-TAG®, a permanent, scannable identification tag with RFID-based traceability that stores the sling's serial number, WLL, inspection history and test certificates across its working life. VIP grade components use master links and connectors designed for anti-confusion locking, so mismatched grade parts cannot be assembled into the same sling by mistake. The chain surface is treated for abrasion and corrosion resistance, which matters on sites where slings sit exposed to weather, coolant or coastal air between lifts. Every component is load-tested before assembly, and the finished sling is proof-tested again, with results logged against its own serial number.
RUD chain slings are used wherever loads are heavy, hot, sharp-edged or irregular in shape. Steel plants and rolling mills use them for coil, billet and scrap handling. Foundries rely on chain over synthetic slings near molten metal and high ambient heat. Construction sites use them for precast beams, rebar cages and structural steel erection. Shipbuilding and ports use chain slings for engine blocks, hull sections and container handling, where abrasion resistance matters. Precast concrete yards use them for panels, culverts and manhole rings. Heavy engineering and machine-building units use them for gearboxes, castings and fabricated assemblies that need a rigid, non-stretch lifting connection.
RUD chain slings are built to order rather than picked off a shelf, so most specifications can be adjusted to match the application. Leg length is set to the job, not a standard catalogue figure, and legs can be shortened later using grab hooks if lift height changes. Hook type is selectable: grab hooks for length adjustment, clevis hooks for a fixed pinned connection, or safety hooks with a spring-loaded latch where the load could shift. Master link size is matched to the crane hook or shackle in use. Chain grade (80 or 100 VIP) and surface finish, including zinc-plated or painted options, are specified at order stage. Endless slings are made to a stated loop length rather than a fixed range of sizes.
RUD India manufactures chain slings to the same design and testing standards as RUD's German operations, with local production reducing lead time against imported slings. Every sling is proof-load tested and issued with a traceable test certificate, so inspection and audit records are available for its full working life. Technical staff review the application, not just the order, checking leg configuration, angle and headroom before confirming a specification. Field support continues after delivery, covering periodic inspection, re-certification and replacement of worn components rather than treating the sale as the end of the relationship. A sales and service network across India's major industrial belts keeps replacement parts and support within reach of most plants.
Ready to specify a chain sling for your application? Share the load weight, the number of legs required and a brief note on the application (indoor, outdoor, corrosive or high-heat environment), and RUD India's technical team will recommend the right chain grade, leg configuration and fittings for the job.
Grade 100 (VIP) chain typically carries 25 to 30 percent more WLL than Grade 80 at the same diameter.
Example: a 2 leg sling built from 10mm Grade 80 chain, rigged at 30° from vertical, carries 3.15 × 1.4 = 4.41 tonnes. The same sling rigged at 50° carries 3.15 × 1.0 = 3.15 tonnes.
Material: Alloy steel, Grade 80 (T) or Grade 100 VIP (V)
Standard compliance: EN 818-4, EN 1677 (components), DIN 5688, IS 2760 (steel chain slings), IS 8324 (safe use and maintenance)
Proof-load testing: Every finished sling is proof-tested to twice its WLL before dispatch, with results recorded against the sling's individual serial number.
