Abstract
A vibration field study was made of heavy equipment operators, an occupational group exposed to whole-body vibrations impinging on the entire body. Track type tractors, scrapers, motor graders, loaders, backhoes, compactors, skidders, and dump trucks were operated by one or two of four operators with differing degrees of experience. Vibration data were obtained from the vehicle floor, man seat interface, as well as from the operator's knee, shoulder, and head. Analysis by the vibration spectra that obtained for the different types of machines indicated, in part, that little difference could be attributed to the experience of body mass of the operator; and that the majority of higher level vibration occurred below the 4 to 8Hz human body resonance band, much of it at less than 1Hz.
