Pole tampers or "pogo sticks" are an everyday tool of the trade for utility field operations. Pole tampers are small, effective soil compactors, appropriate for use in highly confined areas and capable of achieving geo-technical goals over a wide range of backfill soils. Unfortunately, pole tampers expose field personnel to one of the industry's highest levels of hand/arm vibration. Never-the-less, pole tampers have proven difficult to replace. Indeed, as a growing number of utilities adopt "keyhole methods", it is likely that pole tamper utilization will increase as excavation size decreases.
MBW's Ergo-Tamp is a pneumatic pole tamper specifically designed to minimize hand/arm vibration. A patent pending vibration suppressor located at the hand-held end of the tool reduces hand/arm vibration between 50 and 70%, depending on conditions of compaction. Excessive hand/arm vibration is known to contribute to the development of various chronic ailments including carpal tunnel syndrome, white finger and arthritis.
Additionally, the Ergo-Tamp can be equipped with a trigger guard. The trigger guard is a safety feature designed to minimize accidental activation of the compaction shoe.
Norm Coller, Gas Utility Program, Northeast Wisconsin Technical College:
The air operated pogo stick tamper is a tool widely used in the gas industry to ensure correct and safe installation with proper backfilling. Compaction around all underground facilities becomes more important as the competition for underground space increases. This tool has been virtually unchanged since its inception and it has served the industry and the task very well, in spite of its reputation as a tool that makes your body continue to vibrate even after you shut it off. The use for an extended time is hard on body wrist, elbow and shoulder joints and certainly could cause damage over time, much like hearing damage from exposure to noise over time. Our attention to protect workers from overexposure to vibration and growing ergonomic injury statistics make this vibration suppressor from MBW a welcome addition...
