Rigging Hooks & Lifting Hooks — G70, G80 & G100
Rigging hooks are the end fittings that connect a chain sling, wire rope sling or hoist to the load — and, like every other component in a lifting assembly, they're graded, load-rated and stamped for a reason. AIMS Industrial stocks a genuine range of certified rigging hooks from Austlift, Beaver and Yoke, covering swivel hooks, clevis hooks, self-locking hooks, grab hooks, sling hooks, foundry hooks and hoist eye hooks in Grade 70 (G70), Grade 80 (G80) and Grade 100 (G100). For a deeper dive on the standards and selection criteria, see our Lifting Hooks Guide: G80, G100 Eye, Clevis, Swivel & Self-Locking Hook Selection.
Grade matters because it sets the working load limit (WLL) a hook can safely carry for a given size. G80 alloy steel is the long-standing standard for overhead lifting chain and componentry in Australian rigging, while G100 componentry is manufactured to carry roughly 25% more WLL than a G80 hook of the same chain diameter — letting riggers use a smaller, lighter hook for the same rated load, which is why you'll see G100 favoured in mining and heavy industrial rigging where every kilo of gear counts. Grade 70 hooks are a different animal again: in this range they're built and rated for load restraint and chain shortening — lashing capacity, not overhead lifting WLL — so they're not a substitute for a G80 or G100 hook on a crane or hoist.
Whatever grade you're after, every hook needs to be matched correctly to the rest of the rigging assembly, fitted with a working safety latch where the application calls for one, and inspected before use. Below we've broken down the range by hook type and grade, and answered the questions our team gets asked most often about selecting, matching and inspecting rigging hooks.
Rigging Hook Quick Reference
| Hook Type | Grade | Verified WLL / Capacity Range | Typical Use |
|---|---|---|---|
| Swivel self-locking hook (ball-bearing) | G80 | 1 t – 12 t (size dependent) | Crane and hoist rigging where the load needs to rotate free of sling twist |
| Swivel self-locking hook, V Series (ball-bearing) | G100 | 1.4 t – 10 t (6–16 mm) | Same duty as G80 swivel hooks at a higher WLL for the same chain size |
| Clevis / eye sling hook w/ safety latch | G80 | 1.1 t – 15 t | Standard sling-to-crane-hook connection, quick attach/detach |
| Eye self-locking / eye sling hook | G80 | Up to 21.2 t (size dependent) | Wire rope and chain sling end fitting requiring a two-step release latch |
| Clevis grab hook / shortening hook | G80 | 1 t – 15 t | Chain shortening and choke hitching without a coupling link |
| Clevis winged grab hook | G70 | 2,300 kg – 9,000 kg lashing capacity | Load restraint / chain binding — not rated for overhead lifting |
| Eye / clevis foundry hook | G80 / G100 | 2 t – 12.5 t | Slung loads where the wide throat and reinforced saddle suit awkward or hot-yard lifts |
| Container hook (45°) | G80 | 12.5 t (left/right hand pair) | ISO container corner-casting lifting |
| Choker hook | G80 | 3.2 t (10 mm) | Choke-hitch wrap around pipe, timber and structural steel |
| Hoist eye hook (alloy, with latch) | Alloy, non-chain-graded | 1 t – 11 t | Top/bottom connection point on chain blocks, lever hoists and wire rope hoists |

How to Choose the Right Rigging Hook
Match the hook grade to the chain or sling grade — never mix grades
This is the one rule riggers can't afford to get wrong: a lifting assembly is only as strong as its weakest rated component. Fitting a G100 hook onto a G80 chain sling doesn't lift the assembly's rating to G100 — the chain is still the limiting factor, and vice versa, fitting a lower-grade hook onto a higher-grade chain drags the whole assembly's WLL down to the hook's rating. Always select a hook of the same grade as the chain or sling it's terminating, sized to the same chain diameter, so the stamped WLL on the hook and the stamped WLL on the chain actually agree.
Swivel vs. fixed (clevis) hooks
Swivel hooks run on a ball-bearing race that lets the hook rotate under load, which stops the sling or chain twisting as the load turns — the right call for crane rigging, hoist rigging and any lift where the load can spin. Fixed clevis hooks connect via a solid clevis pin straight onto the chain, with no rotation — they're the better choice where you want a controlled, non-rotating connection, such as multi-leg slings converging on a common lifting point.
Safety latch types
Standard sling and eye hooks carry a spring-loaded safety latch that keeps the sling seated in the saddle and stops it riding out under slack or side-load. Self-locking hooks go a step further with a positive, two-step release mechanism that has to be deliberately operated to open — they won't trip open from vibration or an unexpected knock the way a spring latch can, which is why they're specified for critical lifts and dynamic loading. Grab hooks and clevis-pin hooks generally don't carry a latch at all — they rely on the geometry of the connection instead, which is fine for chain shortening but is not a substitute for a latched hook on a general lift.
Load in the saddle, never on the tip
A hook's rated WLL assumes the sling, ring or shackle sits fully in the saddle — the deepest, strongest part of the curve. Point-loading the tip concentrates the same force on a section of steel that was never designed to carry it, and can bend or fail the hook well under its rated capacity. Seat the load properly, every time.
Inspect before every lift
Check the throat opening, look for bends, wear or cracking at the throat (the most highly stressed point on any hook), and confirm the latch closes and locks properly. Any hook showing throat deformation, cracking or a latch that won't seat correctly should be tagged out and taken out of service immediately — don't wait for the next scheduled inspection.
Verified Brands in This Range
Every hook in this collection comes from one of three manufacturers, all represented by genuine, current product lines through AIMS:
- Austlift — the broadest range in this collection, spanning G70, G80 and G100 swivel, clevis, eye, grab and hoist hooks, including the newer V Series G100 line with per-size WLL specifications published on each product.
- Beaver — Grade 80 sling, self-locking, grab, foundry, container and choker hooks with WLL and chain-size data published against every variant, plus a small run of Grade 70 and Grade 100 hooks.
- Yoke — a Taiwanese lifting hardware manufacturer supplying G80 and G100 eye, clevis, sling, grab, self-locking and foundry hooks, with componentry described as design-factor 4:1 proof tested and tested to EN 1677.
We also stock a 316 (A4) stainless swivel slip hook for marine and corrosion-prone environments — a different category to the alloy chain-grade hooks above, and not rated to G70/G80/G100 chain grades, but a genuinely useful option where corrosion resistance matters more than raw WLL.

Rigging Hooks — Frequently Asked Questions
What's the difference between a Grade 80 and a Grade 100 rigging hook?
Grade 100 componentry is manufactured to carry roughly 25% more working load limit than Grade 80 hardware of the same chain diameter. That means a rigger can use a smaller, lighter G100 hook to carry the same rated load as a larger G80 hook — which matters in mining and heavy industrial rigging where hook and chain weight adds up fast. Both grades are alloy steel, batch tested and stamped with size, grade and WLL.
Can I fit a Grade 100 hook to a Grade 80 chain sling, or mix grades generally?
No — never mix grades in a lifting assembly. The assembly's working load limit is set by its lowest-rated component, so pairing a higher-grade hook with a lower-grade chain doesn't increase the assembly's capacity; it just wastes the extra strength of the hook. Always match hook grade to chain/sling grade, and match the size too, so the stamped WLL figures on each component actually correspond to one another.
What's the difference between a swivel hook and a clevis hook?
A swivel hook rotates on a ball-bearing race, letting the load turn freely without twisting the sling or chain — the right choice for crane and hoist rigging where the load can spin. A clevis hook connects via a fixed pin with no rotation, giving a controlled, non-rotating connection that's often preferred for multi-leg slings converging on one lifting point.
Do all rigging hooks need a safety latch?
Sling and eye hooks used for general overhead lifting should carry either a spring-loaded safety catch or a self-locking (two-step release) latch to keep the sling seated in the saddle during the lift. Self-locking hooks are the more secure option for critical or dynamic lifts because they won't trip open from vibration. Grab hooks and some clevis-pin fittings don't carry a latch — they're designed for chain shortening rather than as the primary sling-to-load connection, so check the product is the right type for your application.
What's the difference between a grab hook and a sling hook?
A grab hook (clevis or eye type) is designed to bite onto a chain link, letting you shorten a sling leg or choke-hitch a load — it's an adjustment fitting, not the sling's primary end connection. A sling hook is the terminal fitting on the sling itself, fitted with a safety latch, and is what actually connects to the crane hook or load.
Can a Grade 70 hook be used for overhead lifting?
In this range, Grade 70 hooks such as the Austlift and Beaver clevis winged grab hooks and clevis slip hooks are specified and rated by lashing capacity rather than working load limit — they're built for load restraint and chain-shortening duty, not for general overhead lifting. For crane, hoist or sling work, choose from the Grade 80 or Grade 100 lifting hooks instead.
What standards do these rigging hooks comply with?
Product specifications in this range reference AS 3776 (chain sling componentry) and AS 2741 (shackles) for Austlift's alloy steel fittings, and EN 1677 for Yoke's G80/G100 componentry, which is described as design-factor 4:1 proof tested. Always check the specific product page for the compliance information published against that item, and keep the manufacturer's WLL and grade markings visible on the hook in service.
How do I know what size hook I need?
Match the hook's chain-size rating (in mm) to the diameter of the chain or sling leg you're connecting it to — this is the figure that determines the hook's WLL, not the tonnage alone. Each product page lists the available sizes with the WLL for that size; if you're building or repairing a chain sling assembly rather than buying a complete sling, get in touch with our team and we'll help you match hook, chain and connecting hardware correctly.
