MASE Product Failure Injury Report
Product involved: JCB backhoe
What happened: Person was putting in a sewer line near an existing water supply line. To ensure the water line did not get hit, one worker would use a backhoe to dig, then the other worker would get into the hole and dig by hand for a few inches. Person in hole got hit by backhoe bucket when operator tried to move it right, which it did, but then swung left violently.
Injuries: None listed.
Findings: Appears to be a case of out-of-adjustment hydraulic controls. By the time the unit was inspected, the cover over the foot pedal controls had been removed. The rod that went to the foot pedal control had been recently adjusted. There is a distinct difference in the rod adjustments on the other valves. The linkage threads on the crucial valve are clean as are the nut and clevis. Someone even tried to spot weld the adjustment device so that it would not loosen. The foot pedals that control the left-right movement of the boom looked new. The paint was not worn on the pedal.
OSHA/Standard violations: None found
