Abstract
In response to a request from the Allied Industrial Workers, the International Machinist Unions, and management, an investigation was undertaken of possible hazardous working conditions at Harley- Davidson, Inc. (SIC-3751), Milwaukee, Wisconsin. The facility manufactured and assembled motorcycle parts 24 hours a day, 7 days a week. An ergonomic evaluation of job risk factors for musculoskeletal disorders at the flywheel milling area was performed, and employee medical record data were reviewed. The cumulative weight handled in lifting and transporting flywheels during the milling process was in excess of 14 tons for one worker and in excess of 9 tons for another worker. Data gathered indicated that potential musculoskeletal disorders could result at the elbow, shoulder, back, and hip during manual handling of the flywheel during the milling process. Job risk factors which may cause disorders included manual transport of the flywheel between milling processes, placement of the flywheel in the milling machinery, and removal of this part when milling was complete. Hand and wrist disorders may also result from exposure to hazardous vibration frequencies from a hand held power grinder used to remove metal burrs from milled flywheels and during manual tightening of this part onto the index milling machine. The authors conclude that musculoskeletal hazards existed for the upper limbs and back.
