Overturns – Where is the tipping point?

Uneven ground

MEWPs rely on the strength of the ground and the structure directly beneath them to support the weight, movement and changes to the load in the platform. Where the MEWP touches the ground is often referred to as the ‘point of contact’ – this could be wheels, tracks, stabilisers or outriggers, and this may differ again if the MEWP is mounted to another vehicle or trailer.

Can you spot all of the hazards in this video that may affect the stability of a MEWP?

Rigorous planning is essential when selecting the appropriate MEWP for working at height. Always check:

  • the ground or foundations, to ensure it can take the machine’s weight when loaded;
  • the whole area in which a MEWP will be operated or set up must be thoroughly assessed;
  • the route for the MEWP, which should be walked first by the operator;
  • the likelihood of hazards, such as culverts, ducting or other cavities or structures hidden beneath the surface – wherever possible any hazards should be moved or cordoned off;
  • users and operators should know the rated load capacity of any machine being used and not exceed this.
