Load Restraints — Ratchet Straps, Tie Downs & Chain Binders
AIMS Industrial stocks load restraint equipment for road transport, mining, construction and 4WD/recovery use: ratchet tie-down straps, cam buckle straps, soft-eye axle straps, chain load binders and Grade 70 transport chain, and corner protectors. The range is led by Austlift (our broadest load restraint range), with SmartStraps, Beaver and FASTY covering the rest of the everyday tie-down and chain binder range, plus Raze Ratchet straps and Black Rat recovery straps for 4WD work. We've put together a Ratchet Strap Guide: Types, Sizes & Selection if you'd like more detail before you buy.
Quick reference — restraint type, rating and use
| Restraint type | Typical rating | Sizes stocked | Best for |
|---|---|---|---|
| Ratchet tie-down straps | 250kg–4,000kg LC | 25mm, 35mm, 50mm webbing | General freight, pallets, machinery, vehicles — the workshop default |
| Cam buckle straps | Lower LC, hand-tensioned | 25mm–35mm webbing | Light or fragile loads where ratchet over-tensioning risks damage |
| Soft-eye axle straps | Matched to vehicle/plant weight | 50mm webbing loop | Securing vehicles and plant to axles/wheel hubs without hook damage |
| Chain load binders (lever & ratchet) | 2,300kg–3,800kg+ LC | 6mm–10mm pin diameter | Tensioning Grade 70 chain on heavy machinery and structural loads |
| Grade 70 (G70) transport chain | Rated to the binder/hook assembly | 8mm–10mm chain | Heavy haulage, mining and earthmoving equipment |
| Corner protectors | Up to ~4,250kg LC (webbing type) | Webbing & chain versions | Protecting straps/chain and load edges from cutting and abrasion |
| Recovery / snatch straps | Rated by recovery capacity, not LC | Vehicle-rated | 4WD vehicle recovery — a different job to on-road load restraint |
Ratings above are typical for the sizes we stock — always use the LC (Lashing Capacity) marked on the product's own label or tag for the actual calculation, not a general figure.
Australian load restraint regulation — NHVR and the Load Restraint Guide
Load restraint on Australian roads is regulated under the Heavy Vehicle National Law (HVNL), administered by the National Heavy Vehicle Regulator (NHVR). The technical performance standard is set out in the Load Restraint Guide — now in its fourth edition (2025), published by the NHVR (the guide was previously issued by the National Transport Commission). The performance standard requires restraint sufficient to prevent load movement under: 0.8g forward, 0.5g sideways, 0.5g rearward, and 0.2g vertically (where vertical restraint relies on friction). These figures represent realistic braking, cornering and acceleration forces for a heavy vehicle.
Restraint hardware is rated as Lashing Capacity (LC, kg) for tie-down and lashing use — not the same as breaking strength, and not the same rating system as Working Load Limit (WLL), which applies to lifting and rigging equipment. Don't substitute one for the other: a strap or chain rated for lifting is not automatically rated for tie-down, and vice versa.
The Chain of Responsibility (CoR) provisions under the HVNL extend liability for load restraint beyond the driver to anyone in the supply chain who consigns, packs, loads or receives freight — which means dispatch and warehouse staff carry real responsibility for restraint adequacy, not just the person driving.
Choosing the right restraint — LC, direct restraint and tie-down
NHVR guidance sets out a simple rule for direct restraint (chains or straps run directly from rated anchor points on the load to the vehicle, rather than relying on friction): combined LC should be at least 2× the load weight forward, and at least 1× the load weight sideways and rearward. This is the calculation to use whenever a load has rated tie-down points — most machinery, plant and vehicles.
Tie-down (friction) restraint — straps run over the top of the load and tensioned down — works differently: the strap increases friction between load and deck, so the LC needed depends on how much friction is actually present. A load sitting on bare steel needs more restraint than the same load on rubber matting or timber dunnage, because the deck itself is doing less of the work. The Load Restraint Guide includes reference friction values for common surface combinations — worth checking rather than assuming.
Chain vs webbing: chain and lever/ratchet binders handle higher LC per restraint, resist heat, abrasion and cutting from sharp-edged or hot loads, and don't stretch under load — the right choice for machinery, steel and mining equipment. Webbing straps are lighter, quicker to rig, won't mark painted or polished surfaces, and are gentler on the load — the right choice for general freight, vehicles and anything where a chain could scratch or dent. Neither is a universal answer; match the restraint to the load.
Inspection and retirement
Check every ratchet strap, cam buckle strap, chain and binder before each use: webbing for cuts, fraying, chemical staining or UV stiffening; hooks and end fittings for cracks, bending or gouging; ratchet mechanisms for worn pawl teeth or a handle that won't lock; chain links for stretch, nicks or corrosion. Any of these takes the item out of service immediately — there's no partial-credit inspection. Retire any restraint after a shock load or overload event even if it looks undamaged. Dry webbing thoroughly before storage; wet webbing left coiled in a toolbox or ute tray encourages microbial growth that weakens the fibres, and UV exposure degrades nylon and polyester over time even in storage.
Load restraints we stock — brands
Austlift is our broadest load restraint range — ratchet tie-down straps across 25mm to 50mm webbing, soft-eye axle straps, lever and ratchet load binders, Grade 70 transport chain, corner protectors for both webbing and chain, and motorbike/vehicle tie-down sets. SmartStraps covers ratchet and cam buckle tie-downs, tarp straps and bungee cord. Beaver is our chain and load binder specialist — Grade 70 lever and ratchet-type binders in several hook configurations. FASTY supplies ratchet straps across the common webbing widths. We also stock Raze Ratchet tie-down straps and Black Rat recovery/snatch straps for 4WD work — a related but distinct product, rated for vehicle recovery rather than road-transport load restraint.

Load restraints — frequently asked questions
What's the difference between LC and WLL ratings?
LC (Lashing Capacity) is the rating for tie-down and lashing equipment under AS/NZS 4380 — it's what applies to load restraint. WLL (Working Load Limit) is the rating for lifting and rigging equipment. They're different test methods and aren't interchangeable: a strap rated for lifting isn't automatically rated for tie-down, and a tie-down strap should never be used for lifting.
How many ratchet straps do I need for my load?
Where the load has rated tie-down points, use the NHVR direct restraint rule: combined LC of at least 2× the load weight forward, and 1× sideways and rearward. For a 2,000kg load with rated anchor points, that's 4,000kg of combined forward LC — two 2,500kg LC straps covers it with margin. Friction (tie-down) restraint needs a separate calculation based on the friction between load and deck, which the Load Restraint Guide covers in more detail.
Ratchet strap or chain and binder — which do I need?
Ratchet straps suit general freight, pallets and vehicles — they're quick to rig and won't damage painted or finished surfaces. Chain and binders (typically Grade 70, or G70) suit heavy machinery, steel and abrasive or hot loads, where the higher LC per restraint and resistance to cutting matter more than convenience. Most transport operations use both, matched to the specific load.
What width ratchet strap do I need?
As a rough guide across the range we stock: 25mm webbing runs roughly 250–750kg LC (light freight, motorbikes); 35mm runs roughly 700–1,500kg LC (general transport); 50mm runs roughly 1,000–4,000kg LC (heavier freight and machinery). Always check the LC marked on the actual strap — width is a guide, not a substitute for the rated figure.
Cam buckle or ratchet — which strap for a fragile load?
Cam buckle straps are hand-tensioned and can't over-tighten the way a ratchet can, which makes them the safer choice for motorcycles, panels, glass and anything vibration-sensitive. Ratchet straps deliver much higher, more precise tension and suit heavier general freight where the load can take it.
What is a soft-eye axle strap for?
A soft-eye axle strap loops directly around an axle, wheel hub or suspension component with no metal hook — avoiding the gouging and long-term damage a hook causes on these surfaces. Use it wherever a vehicle or piece of plant is being secured directly to its axle rather than to a chassis tie-down point.
What do corner protectors do, and when do I need them?
Corner protectors sit between the strap or chain and a sharp load edge, spreading the load and stopping the restraint from being cut or abraded through. They're standard practice on any load with square steel edges, timber crates or angular machinery — a strap that's been cut partway through by an unprotected edge has lost most of its rated capacity without any visible sign from the outside.
Is a recovery/snatch strap the same as a load restraint tie-down strap?
No — a recovery (snatch) strap is designed to stretch and absorb kinetic energy when recovering a bogged or stuck vehicle, and is rated by vehicle recovery capacity rather than Lashing Capacity. It isn't a substitute for a rated tie-down strap and shouldn't be used for on-road load restraint, and a tie-down strap shouldn't be used for a vehicle recovery.
What Australian regulations apply to load restraint?
The Heavy Vehicle National Law (HVNL), administered by the NHVR, governs load restraint on Australian roads. The technical requirements sit in the NHVR's Load Restraint Guide (4th edition, 2025), which sets the performance standard restraint must meet. Non-compliance found at a roadside inspection can mean a defect notice, an on-the-spot fine, or the vehicle being held until the load is re-secured.
What is Chain of Responsibility, and does it apply to warehouse staff?
Chain of Responsibility (CoR) is a set of HVNL provisions that make everyone in the transport supply chain — not just the driver — legally responsible for safety, including load restraint. That includes anyone who packs, loads, consigns or receives freight. Practically, that means dispatch and warehouse staff loading a truck share responsibility for the load being adequately restrained before it leaves the dock.
How often should I inspect and replace ratchet straps and chain binders?
Visually inspect before every use — webbing for cuts, fraying or UV/chemical damage, hooks for cracking or bending, ratchets for worn pawls, chain for stretch or corrosion. Any of these means immediate retirement; there's no fixed replacement calendar, but straps in regular outdoor trade use typically need replacing well within a couple of years as wear accumulates. Retire anything involved in a shock load or overload event regardless of appearance, and keep straps dry in storage.
Are ratchet straps suitable for motorbikes and quad bikes?
Yes, with the right setup: a front wheel chock or cradle to hold the bike upright, four corner straps to compress the suspension and lock it to the deck, and soft loops or strap protectors wherever a hook would otherwise sit against anodised or painted surfaces. Lower-LC straps suited to the bike's actual weight are usually the better choice over heavy-duty freight straps, which can over-tension a lighter machine.
