8/1/2008 - Conference papersThis testing monitored the performance of older and newer truck models relative to whole-body vibration (WBV) exposures as a means for determining when the vehicle (e.g., suspension system) and seats required maintenance or replacement.
-
8/1/2003 - Conference papersThis study assessed the adequacy of cab design and determined the percentage of musculoskeletal symptoms among operators of heavy construction equipment.
-
9/1/2010 - Conference papersThis study assessed the difference between free cadence walking versus stoopwalking (under a 1.2-m ceiling), four-point crawling (hands and knees), and two-point crawling (knees only), both with and without kneepads.
-
8/1/2010 - Conference papersNIOSH investigated muscle activity, forces, stresses, and moments at the knee (with and without kneepads) while subjects assumed various postures, including kneeling in full flexion, kneeling at 90° of flexion, kneeling on one knee, and squatting.
-
10/1/2009 - Conference papersBy surveying experienced equipment operators about visual cues, researchers developed a method to gather data on the needs and practices of machine operators while controlling the machine and the reasons for needing particular operational cues.
-
8/1/2009 - Conference papersThe pressure applied to the patella and combined PT and TT was determined for postures associated with low-seam mining.
-
8/1/2009 - Conference papersIn this study thigh-calf and heel-gluteus contact forces were quantified to on the externally applied flexion moment in high flexion.
-
4/1/2008 - Conference papersThrough modeling, this paper analyzes the performance of vehicle operators when subjected to vibration from rough road conditions, and quanttifies the energy transmission in the presence of specialized seat padding and active suspension.
-
11/1/2006 - Conference papersResearchers performed laboratory studies on four passive and two semi-active seat suspension designs. These six seat suspension systems were tested and analyzed, for vertical vibration only, using the ISO 5007 Standard.
-
10/1/2006 - Conference papersRoof screen is often bolted to the mine ceiling to help control hazardous rock falls in coal mines. This study showed that musculoskeletal stressors during screen installation were reduced by a proposed intervention.
