Summary: After parking a utility vehicle in the lower quarry bench, an operator of a 40 tonne articulated haul truck parked about 1.5 metres from the back of the utility. The operator exited the haul truck and walked to another area of the quarry. When a leading-hand worker was obtaining something from the front of the utility vehicle, the haul truck rolled forward and rested against the rear tailgate of the utility causing minor damage to the tailgate. No injuries occurred.
Recommendations to industry: Mine operators should review park-up procedures with operators for specific plant with operators. Safety critical systems such as braking and steering systems should be inspected, maintained and tested in accordance with the manufacturer’s recommendations.
