Truck loading or unloading operations: Reduction of the whole-body vibration exposure of pallet truck drivers at the dock leveller location

Whole-body vibration (WBV) is a recognized health hazard that primarily affects the musculoskeletal system of human beings. Although research works on WBV are documented, for the past few decades or so, researchers are still attempting to explore the role of contributing factors of WBV for the causation of musculoskeletal disorders (MSDs). Therefore, this paper synthesizes up-to-date knowledge on WBV with respect to measurement methods, critical vibration magnitudes, contributing factors, and effects on human health. The present review is based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) that includes 112 studies on WBV exposure and its contributing factors. It also summarizes the contributing factors of MSDs that include personal factors, environmental factors, machine-related factors, and WBV exposure of the heavy vehicles and equipment operators across various industries. Most of the studies reported lower back pain as the most common MSDs experienced by the vehicle operators exposed to WBV, followed by upper back pain. However, it is apparent from the prevailing literature that musculoskeletal health risks do not result from exposure to WBV alone. The role of multivariate contributing factors should also be considered, analyzed, assessed, and understood to establish correlations between these factors with the development of MSDs. In addition to the measurement and assessment of WBV as per the ISO guidelines to evaluate the potential and likely health risks faced by the heavy equipment operators, researchers should also focus on studying various impacts of WBV, and understanding the role of its contributing factors on human health using advanced machine learning tools.

“…Randall (1992) and Aradom and Gebresenbet (2013) showed that during transportation pigs were subjected to vertical, lateral, and horizontal vibrations induced by vehicle motion which displaced the pig's center of gravity, causing discomfort and movement sickness. Vibrations are primarily caused by road surface roughness, undulation curvature, variations in speed, and poor suspension systems (Gebresenbet et al, 2003;Rebelle, 2021). Currently, the International Organization for Standardization (ISO) 2631-1 provides exposure action values (EAVs; injury possible) and exposure limit values (ELVs; injury likely) as guidance for whole-body vibration levels that are uncomfortable and potentially dangerous for humans (ISO 2631(ISO -1, 1997ISO 2631ISO -5, 2018.…”

The objective of this study was to collect and quantify three-axis acceleration data from six locations within commercial pig transport trailers during summer. Two trucks with straight-deck trailers transporting two loads per day were observed for 5 consecutive days (N = 20). Accelerometers were placed under the floor of each trailer’s top and bottom decks (DECs) in the center of three sections (SECs): fore, middle, and aft. Data from each trailer section were processed to calculate z- and x,y-axis root mean square (RMS) values and vibration dose values (VDVs) during loading, transport, and unloading. There were no DEC × SEC interactions or SEC main effects for z-axis RMS or VDV during any transportation stage (P > 0.06). The bottom deck had a greater x,y-axis RMS than the top deck during all transportation stages (P < 0.01). The bottom deck had a greater x,y-axis VDV than the top deck during loading and transport (P < 0.03), but there was no difference (P = 0.52) during unloading. The bottom deck had a greater z-axis RMS and VDV than the top deck during loading and transport (P < 0.01), but there were no differences during unloading (P > 0.07). There were no SEC effects for x,y- and z-axis RMSs and VDVs during all transportation stages (P > 0.06). Acceleration values were compared with exposure action values (EAV; injury possible) and exposure limit values (ELV; injury likely) vibrations thresholds. Over the 5 observation days during all transport stages, a greater percentage of compartments violated both RMS and VDV thresholds in the x,y orientation (average 90%) than in the z orientation (average 76%). Overall, these data indicate that bottom decks experience greater three-axis vibrations than top decks in straight-deck trailers and that pigs on bottom decks may experience greater discomfort during transportation that could contribute to fatigue or the non-ambulatory condition.
