Understanding Stop Blocks

Stop blocks are designed to be used in pairs, positioned behind a wheel to prevent unintended movement of vehicles or equipment. In mining environments, characterised by the operation of diverse large haul vehicles, the use of stop blocks is particularly crucial due to the substantial risks posed by these heavy machines.

However, stop blocks extend their utility beyond mining; they find extensive application in road construction, where they secure vehicles and equipment on uneven surfaces or inclines.

The Importance of Stop Blocks

When positioned correctly, stop blocks are highly effective and reliable safety products to use on site. However, their proper usage involves several key considerations that may not be immediately apparent to every user.

Below you will find a list of the do’s and dont’s related to stop blocks.

Selecting the Right Stop Blocks

It is important to choose the right stop blocks for your environment and vehicles as using the incorrect stop block may result in the stop blocks not working. Consider the following factors:

  • Size of the wheel: Tyre diameter considerations are crucial before selecting stop blocks.
  • Weight of the Operating Vehicle: Select blocks that match the weight of the vehicle for adequate support.
  • Grade of the Ground Surface: Position blocks differently depending on the surface, and consider using multiple blocks for wet or muddy conditions or those with cleated bottoms for icy or slippery surfaces.
