Abstract
Vibration characteristics of jack leg drills, jack hammers and slushers were surveyed. Instrumentation and test procedures were described in a previously reported study. Information on overall acceleration levels and the total work per unit time for the tools, acceleration time histories of the tools, measured acceleration levels on the tool handles, calculated energy levels into the hands, and the power levels into the hand was presented. The total work per unit of time for the large jack leg drill was greater than that of the jack hammer at similar overall acceleration levels, and the difference was associated with the direction in which the hands were excited. For the jack leg drill, the hand was excited in the horizontal direction, while the hand was excited in the vertical direction with the jack hammer. These differences also were achieved for the horizontal and vertical directions for the slusher.
