Abstract
The objective of this study was to determine optimal personal equipment design for use in low coal based on ergonomic, biomechanic, and safety considerations. This report describes three experiments that were conducted to determine the effects of size and weight of battery packs. The first experiment tested the sensitivity of task measures; that is, workers performed locomotion, shoveling, cart pushing, and timbering tasks to detect variations in the size and weight of battery packs. The results showed that only locomotion was sensitive to size and weight variations. The second experiment focused on locomotion tasks and tested the effects of varying size and weight on task completion time. The third experiment compared the battery pack presently in use with a radically different configuration of power cells. The most important findings were that changes in weight affected locomotion times but changes in size and configuration had small and inconsistent effects. Workers indicated a strong preference for a battery pack belt concept.
