Using MEWPs among trees: Work site safety

• Carry out pre-use checks before using any MEWP. Always check for damage or faults, and isolate, tag and report any defects.
• Plan and walk the route – getting to and from the work site may involve manoeuvring the MEWP over challenging terrain. For vehicle-mounted platforms, consider a four-wheel-drive unit.
• Track-mounted MEWPs should be manoeuvred with outriggers partially deployed so if the MEWP becomes unstable while being driven it reduces the risk of an overturn (see illustration).
• Make sure the ground can support the weight of the MEWP and its load – on 1b-type machines use spreader pads to distribute weight evenly. Consideration must be given to the point-load pressures when MEWPs have more weight over one side of the machine – this can be up to 80% of the machine’s total weight.
• Ensure MEWPs are set up and levelled correctly, on firm surfaces, and are not at risk of being struck by other vehicles or machines.
• Always set up well away from edges, verges or steeply sloped banks.
