Manual Materials Handling Capabilities in Non-Standard Postures.

摘要

Research efforts to establish manual materials handling capabilities of individuals and populations have been conducted for many years at Texas Tech University. Recognizing that all industrial materials handling activities are not two handed symmetric sagittal plane activities, recent research projects have explored materials handling capacities in non-standard postures. Among the nonstandard postures examined were: twisting while lifting or lowering, lifting and lowering from lying, sitting, kneeling, and squatting positions, and carrying loads under conditions of constricted ceiling heights. Capacity data are presented for both males and females. In addition to means and standard deviations of the data, percentile distributions for the subject populations are also presented. Sample sizes for the experimental populations range from 20 to 50 subjects of each sex.
