Manual Materials Handling
These online "Liberty Mutual Manual Materials Handling Tables" are based on the maximum acceptable weights and forces published by Snook and Ciriello in 1991. These online tables provide both the male and female population percentages capable of performing manual material handling tasks without over
exertion, rather than maximum acceptable weights and forces published in 1991. This manual material handling analysis online tool can be used to perform ergonomic assessments of lifting, lowering, pushing, pulling, and carrying tasks with the primary goal of supporting ergonomic design interventions.
For a detailed description of the LM Tables please read the Liberty Mutual Manual Materials Handling Tables.
