A vehicle that shifts during loading, unloading or maintenance is one of the most common causes of serious injury on a yard or loading bay, and a heavy duty rubber wheel chock is the simplest way to stop it happening. Wedged against a tyre, it holds HGVs, vans, trailers, diggers and other plant securely on both flat ground and slopes, giving your team a reliable last line of defence against unexpected roll-away.

Why it works

The chock is moulded from a single block of solid rubber rather than a hollow shell, so it keeps its shape under sustained load instead of compressing or splitting. A ribbed tread runs across the full contact face, biting into the tyre tread to resist slipping even when the ground is wet, oily or frosty. Because the body is solid rubber rather than steel or hard plastic, it will not mark tyres, will not rust, and will not crack in cold weather the way some lower-cost chocks do after a winter outdoors. A drilled hole through the wedge accepts a rope or chain, so the chock can be tethered to the vehicle or a fixed point and never gets left behind on site.

• Solid rubber build – resists compression and splitting under repeated heavy loads
• Ribbed grip face – maintains traction on wet, icy or oily surfaces
• Rope hole fitted – tether it to the vehicle so it is never lost or left behind
• Weatherproof rubber – will not rust, rot or crack outdoors year-round
• Two size options – matched to tyre diameter for vans, HGVs, diggers and dumpers

Wheel chocks like this one are specified wherever vehicles stand unattended with an engine off and a handbrake that cannot be fully relied on: loading bays, distribution yards, vehicle workshops, construction sites and plant depots. They are equally at home under a parked HGV trailer awaiting a tractor unit, a van on a sloped forecourt, or a digger left overnight on site.

Specifications

Choosing the right size: match the chock to the tyre it will be holding rather than to the vehicle type alone, since a chock that is too small can be driven over rather than stopped by. As a working rule, chock height should be at least a quarter of the tyre's overall diameter. The 300mm chock suits vans, cars, small trailers and light plant with a tyre diameter up to roughly 900mm. The 400mm chock is sized for HGVs, tractor units, dumpers and diggers with larger tyres, and gives a greater margin on inclines. If you are chocking a laden HGV on a slope, fit chocks to more than one wheel rather than relying on a single chock.

Installation, use and care

Position the chock hard against the tyre tread on the downhill side of the wheel, so that any rolling motion drives the tyre further onto the chock rather than away from it. On a slope, fit a chock to the downhill side of at least one wheel on each axle; two matched wheels is safer still. Push the vehicle gently onto the chock to seat it before leaving the vehicle unattended. Store chocks away from fuel, oil and direct sunlight when not in use, and inspect the rubber periodically for cracking, tearing or a permanent compression set, replacing the chock if any of these are found.

Frequently asked questions

How many chocks do I need per vehicle?
One chock per wheel is the minimum on level ground; on a slope, chock at least one wheel on each axle, or both wheels of the same axle for extra security.

Will this chock damage my tyres?
No. The solid rubber body and ribbed face are designed to grip the tyre without marking or damaging the rubber, unlike some steel or hard plastic alternatives.

Can it be used on gravel or uneven ground?
It performs best on hard, level surfaces such as concrete or tarmac. On loose or uneven ground the chock may not sit flush, so use a flat base pad underneath or add extra restraints on steep or unstable surfaces.
