8/1/2003 - Conference papersA multi-body biomechanical model was developed that can be used to assess the risk of low back disorders due to occupational exposure to jarring and jolting from operation of heavy mobile equipment (e.g., trucks, haulers, graders, tractors, etc.)

8/1/2003 - Conference papersA field study was conducted to evaluate four seat designs on shuttle cars, including two NIOSH-designed seats.
-
4/1/2002 - Peer reviewed journal articlesThis study evaluated spinal loads associated with lifting and hanging heavy mining cable in a variety of postures.
-
7/1/2001 - Peer reviewed journal articlesThe objective of this study was to systematically characterize the ergonomic hazards associated with excavating operations.
-
3/1/2001 - Peer reviewed journal articlesCoal miners often handle heavy electrical power cables, weighing up to 10 kg per meter. These cables are manually lifted and attached to the mine roof to prevent damage from mobile underground equipment.
-
1/1/2001 - Conference papersThis paper presents a technique for representing and analyzing random motions and hazardous events in a computer simulated three-dimensional workplace, providing machine designers and safety analysts with a new technique to evaluate ways to reduce opera...

8/1/2000 - Peer reviewed journal articlesThis paper discusses the application of global positioning system (GPS) data, accelerometers, and pressure transducers to provide feedback about equipment operations and identify the cause of truck jolts.
-
12/1/1999 - Peer reviewed journal articlesWith input from underground shuttle-car operators, this study addressed a component of WBV that is germane to underground mining: high-energy impacts or shocks.
-
3/1/1998 - Conference papersThe prolonged exposure of equipment operators to shock and whole-body vibration (WBV) is linked to cumulative back, neck, and abdominal disorders.
-
10/1/1997 - Conference papersTwelve subjects participated in an investigation of the biomechanical stresses of asymmetric lifting in stooped and kneeling postures. Three factors were manipulated in this study: posture (stooped or kneeling), height of lift (35 or 70 cm), and weight ...
