Why AMPTAMP is better than old tampers:
New patent allows use of granular media in a hollow chamber of the tamper for amplification.
Reduces arm-numbing shock, bounce, and recoil
With old steel tampers, part of the kinetic energy from the operator’s arms "comes back" as recoil/bounce transferred back into the handle and the arms of the operator. and is not applied into the ground for compaction. Recoil and shock through the handle cause user fatigue, hand, wrist and elbow stress. Repetitive stress injuries, according to the Occupational Safety and Health Administration, cost employers $15 billion per year. With AMPTAMP, absence of recoil can transfer more kinetic energy into ground compaction than a static device and is proven to reduce shock and fatigue to the operator.
Adjust to the weight you want.
Need more weight? Just add water! Or sand. Or for a real surprise, add steel BBs. Old steel tampers are set at one weight. With AMPTAMP, you set the weight you want by adding water, sand or BBs.
More efficient transfer of impulse energy into the soil.
Old steel tampers bounce when striking the ground. With AMPTAMP, granular damping material slows down the duration of impact, reducing (or eliminating) bounce and can transfer more kinetic energy into ground compaction--instead of back into the operator's arms! Combined with optimal weight, less fatigue, and application of Newtonian physics, AMPTAMP does more work for less effort.
Already proven superior to old static tampers, AMPTAMP is currently in prototype use and is the result of significant testing and optimization of application of Newtonian physics to soil compaction via hand operated tools. Use of granular damping for tamping is protected by US patent 9487927 granted Nov 8, 2016. Inquiries into licensing for manufacture or purchase are invited.
