During the cleaning out of a run-of-mine (ROM) crusher bin at an Eastern Goldfields mine, two maintenance personnel were crushed between the bin and an excavator counterweight. They sustained serious injuries, including multiple fractures.

The excavator was being used to clean rocks from the crusher bin to allow maintenance work to be carried out. This involved the excavator bucket reaching into the bin, removing loose rock and placing it beside the bin. The incident occurred when the slewing action of the excavator created a pinch point between the counterweight and bin’s concrete sidewall when tipping a bucket of rock beside the bin.
