Operator crushed by backhoe boom while doing maintenance.
NIOSH 1999 Nov; :1-4
In May 1999, a 75-year-old owner of a well-drilling business was killed while servicing a company tractor backhoe. The victim and his employee were performing routine maintenance on the machine, tightening a large nut, which connects the backhoe boom to main tractor frame. The boom was extended straight out to the back of the machine. The victim was standing on the ground behind the tractor next to the boom. The tractor was running, and the hydraulics of the backhoe were connected and operational. When the victim apparently reached for a wrench, he accidentally leaned on the foot pedal which operates the boom sideways movement. The extended boom immediately swung towards the operator, crushing him against the raised outrigger. The other worker was preparing to grease the bucket joints at the time, and was not injured. The victim died shortly after from crushing injuries to the chest. Recommendations based on our investigation are as follows: 1. Machines should not be serviced while the engine is running. 2. Machines should be maintained in safe condition to avoid malfunctions and increased maintenance.
