Lifting pulleys, snatch blocks and sheaves for planned rope handling

Industrial Shed’s Lifting Pulleys & Sheaves collection is a dedicated home for rated snatch blocks and sheave-based lifting hardware used in rope-handling and rigging arrangements. It is deliberately separated from our power-transmission pulleys so a customer planning a lift is not sent to belt-drive components that are unsuitable for lifting work. The collection currently centres on verified Austlift snatch blocks and yoke assemblies, alongside a Schutts Industrial crane-lifting snatch-block sheave.

What you will find in this collection

The available range includes hook-head, shackle-head and yoke-style snatch blocks for selected steel-rope sizes and lifting arrangements. Product titles confirm a spread from a 750 kg webbing model through 2 t, 4 t, 6 t, 8 t, 10 t, 12 t, 15 t, 20 t, 22 t, 30 t and 50 t rated configurations. Those figures identify individual products, not a blanket rating for every item: select the exact item only after checking its stated working load limit, rope compatibility and connection style.

Choose a block by the complete system, not the load alone

Start with the verified load weight, centre of gravity, intended line of pull and the rope that will run in the sheave. Then confirm the product’s working load limit, the stated compatible rope diameter, the sheave profile, head fitting and the proposed anchor point. A hook-head block, shackle-head block and yoke assembly solve different connection problems. A yoke is not interchangeable with a complete block unless the supplier’s documentation expressly permits that arrangement.

Where a rope needs to be redirected, a snatch block can support a planned line route and, in suitable systems, help create mechanical advantage. The opening side-plate arrangement can simplify installation around an appropriate rope; it does not make side loading, shock loading or improvised anchorage acceptable. The full lifting system is only as strong as its lowest-rated compatible component.

Steel-rope and connection compatibility

Several Austlift products in this range identify specific steel-rope bands in their titles, such as 8–9 mm, 10–13 mm, 13–16 mm, 16–18 mm, 18–20 mm, 20–22 mm, 24–26 mm, 28–32 mm, 32–36 mm and 44–50 mm. Treat these as product-specific guidance. Confirm the supplier information on the item page before purchase, particularly where rope construction, hook opening, shackle pin diameter or the load path differs from a straightforward vertical lift.

For compatible components, explore Chain, Wire & Rope and Lifting & Jacking Equipment. Those collections help complete a system, but components must still be selected and checked together by a competent person.

Safe use in lifting and rigging work

Before each use, inspect the block body, sheave, pin, hook or shackle head, rope contact surfaces and any latch or retaining hardware. Remove equipment from service if it is deformed, cracked, excessively worn, damaged by heat or corrosion, or missing its identification. Confirm the load is controlled, keep people clear of suspended loads, prevent side pull and avoid shock loading. Never exceed the product’s stated working load limit or use a drive pulley, belt pulley or unmarked sheave as lifting equipment.

Plan lifts with appropriately rated and compatible attachments and anchorage. Ensure the supporting structure is suitable, establish exclusion zones and follow the manufacturer’s instructions together with your site’s lifting procedures. Lifting equipment supports controlled handling; it is not a substitute for a lift plan, inspection regime or competent supervision.

Questions about lifting pulleys and snatch blocks

Can I use a power-transmission pulley for a lift?
No. Belt-drive and timing pulleys are not lifting devices. Use only equipment specifically identified and rated for the intended lifting or rigging arrangement.

Does a larger-capacity snatch block make every part of the system higher rated?
No. The usable capacity is limited by the lowest-rated compatible rope, connection, anchor and component in the system. Verify each item before work starts.

Why does the rope-size range matter?
The rope needs to sit correctly in the sheave and work within the product’s stated compatibility. An incorrect rope size or profile can damage the rope or block and compromise control.
