What size Wheel Chock do I need?

When choosing your wheel chocks, it is important to know exactly what size you need

Follow these simple 5 Wheel Chock rules:

  1. The height of the wheel chock should be 25% of the height of your wheel and fit snugly against your tyre. For example, a wheel 600mm high, would require a wheel chock of 150mm.
  2. When parking on a gradient, at least two wheel chocks are recommended.
  3. The majority of mine and big construction sites in Australia require all vehicles to have a set of wheel chocks.
  4. Park with wheels turned so that, if the vehicle rolled, it would roll towards the kerb, where possible.
  5. Leave a slight gap between the chock and the wheel, to indicate whether the vehicle has moved since placing the chocks. Leaving a gap may not be appropriate when people are working around the vehicle, such as when undertaking repair or maintenance work.

“Vehicles that are not immobilised properly can pose serious risks to workers and others. Vehicle roll-aways result in a significant number of serious injuries and fatalities in Australia each year.
Roll-aways can occur with any type of mobile plant including cars, forklifts, trucks, tractors, trailers, passenger vehicles and heavy machinery. Roll-aways can occur on worksites, car parks, maintenance yards or when a vehicle is parked on the side of the road.
When vehicles that have not been safely immobilised roll-away, a person could be hit, crushed, trapped or run over, leading to serious injuries or fatalities. Injuries can also occur when a person tries to enter or exit a vehicle that has begun to roll-away.”
