  Approximately 1.6 million commercial construction workers in the U.S. use rotary hammer drills for drilling into concrete to insert anchor bolts or set rebar. Depending on handle vibration acceleration level, hand grip force, and duration of exposure, this work may lead to hand-arm vibration syndrome and other musculoskeletal disorders. Currently, however, there is little information on the relationship between feed force (FF)—that is, the push force applied by the worker—and handle vibration. To begin to fill this gap, the research team used a robotic test bench for rotary hammer drills they had previously created to evaluate the effects of different FF on handle vibration and productivity, such as penetration rate and holes drilled.
