## Narrative

The injured employee was moving mud boxes within a tunnel operation using a locomotive. An overhead crane was used to bring the loaded boxes out of the shaft. A loaded mud box was still attached to a locomotive when it was hoisted by the overhead crane and raised about 3 to 4 feet. The hitch broke causing the locomotive to drop to the bottom of the shaft and the operator's chest struck the control panels. The locomotive operator suffered a broken rib and internal bruising and was hospitalized.
