SUMMARY

A 47-year-old mechanic was killed by an excavator bucket during a maintenance operation. The conveyor on a portable rock crusher had stopped working, and the mechanic and equipment operators were working to raise the conveyor with the arm of a hydraulic excavator to get underneath. The mechanic stood on the conveyor, 15 feet above the ground, to complete the task of rigging a chain to attach the frame of the conveyor to the lifting eye on the excavator bucket – when the excavator boom suddenly dropped and swung, and crushed him. The excavator operator had leaned forward for a better view of the mechanic working at the bucket, and when sitting back down the pocket of his raincoat caught on the left-side control handle for the boom, and activated it.
