| Summary |
"U.S. Army members undergo high biomechanical stresses, when performing tough manual material handling (MMH) tasks such as the assembly of a Medium Girder Bridge (MGB). High biomechanical stresses often lead to various musculoskeletal disorders in the people undertaking these tasks. The bridge components are extremely heavy and are designed to be carried using simple tools not manually. A study was done by Kotian and Davis applying in 2005 applying Human Factors Engineering and Mechanical Engineering methodologies to MGBs Mechanical assists were designed to reduce injury caused by manual material handling of bridge components. The approach for the current research involved phases of Finite Element Analysis (FEA) on most critical parts of the crane followed by fabrication of a crane based on the outcome of the FEA results. This research involved design calculations, testing of each and every component of the crane using FEA analysis, and optimizing the design whenever needed"--Abstract, leaf iii. |
