Safety features for self-propelled mobile work equipment - fact sheet

Roll-over structures and seat belts for self-propelled mobile work equipment

All self-propelled mobile work equipment (except those excluded below) must be fitted with safety features.

As an employer you need to ensure that this equipment has a seat belt and a suitably protective roll-over structure (such as a safety frame on a tractor). To avoid roll-over you can also consider improving the equipment’s stability or levelling the work area if possible.



  • Agricultural harvesters or tractors
  • Car, van, truck, or buses
  • Cranes
  • Drag lines
  • Fork-lifts with telescopic booms
  • Log haulers
  • Paving machinery
  • Power operated elevated work platforms
  • Machinery that has a mass of 700 kilograms or less
  • Machinery used in a mine, quarry, or tunnel
  • Anything designed to be used on level ground at all times, so long as you ensure that employees only use it on level ground at your worksite.



If equipment gets damaged and safety is compromised, no employee can use it until it’s replaced, or repaired to manufacturer’s specifications.


Exemption certificates

The Ministry can grant an exemption certificate for specific equipment if satisfied that the conditions imposed are either unreasonable in the circumstances, or unnecessary to protect employees. It can also cancel the exemption certificate but must give a reasonable end date and notify the employer of the cancellation and end dates. If the certificate wasn’t issued to a particular person the Ministry will publish a Gazette notice showing the cancellation and end dates of the exemption.
