Being heavy and cumbersome, and offering only one or two standard handles, Jackhammers are not optimal in terms of ergonomic considerations. Vibration aside, the inability to change one’s posture means that user discomfort is amplified by the long periods over which jackhammers are typically used. Wrist, back, shoulder and neck pain can result, along with fatigue.
Inspiration was drawn from the drop handlebars of racing bicycles to transform the user’s engagement with Tripod Breaker. Its single streamlined handle allows for multiple postures during the use of the jackhammer. Additionally, a tripod-style leg can be expanded at its base, allowing the self-supporting jackhammer to be stood up straight and user fatigue to be diminished. A shock absorber at the top of the chisel diminishes the vibration felt by the user.
