MineChock™ is National Plastics & Rubber’s range of heavy-duty wheel chocks, manufactured in Australia from slip-resistant polyurethane and designed to immobilise everything from light site vehicles through to ultra-class haul trucks.
Every chock in the range is a one-piece moulding, with no fasteners, welds or assembled parts to fail. Mining wheel chocks face conditions that break conventional products. Our products are designed to guard against oil and fuel spills, chemical exposure, constant impacts, and operator handling dozens of times per shift. Our range is engineered to deliver high performance in all conditions, supporting your long-term operational needs.
The range is sized by tyre diameter rather than by vehicle model, which means one size will typically cover several machines across a mixed fleet. When selecting, work through these factors:
Selecting wheel chocks for heavy equipment comes down to four things: the tyre diameter the chock sits against, the vehicle’s laden mass, the surface gradient, and how the chock is stored and carried on the machine.

MineChocks™ are designed to be used in at least two at a time, on low-to-minimal gradients. A site-specific risk assessment should always be completed before use.
A wheel chock is the last thing between a parked machine and an uncontrolled roll, which is why every MineChock™ carries a published tyre diameter range and a tested capacity to ensure a lasting hold. Enquire with our team to outfit your fleet and provide specialised parts to support your site’s operations.
