In a recent metal/nonmetal mine fatality, a mechanic was killed while checking for a hydraulic leak on an Atlas Copco ST-8B Scooptram, the Mine Safety and Health Administration (MSHA) reports.

While checking for a hydraulic leak, the victim leaned into the ejector plate relief port in the back of the loader bucket. The ejector plate of the bucket was retracted, crushing him against the back of the bucket, according to MSHA.

Atlas Copco has developed a general hydraulic system safety notice that they are distributing to all of their LHD and Truck customers, according to MSHA. The safety notice was developed to remind workers to take the necessary precautions before and during work on a hydraulic system.

The safety notice will be included in all Parts Books and Service Manuals for the model numbers in the attached service news.
