26/03/2012· Now although some vibration may be found reverberating through the hammer and object upon impact, this will be relatively short duration and high frequency. What I think your meter is picking up is the massive deceleration of the hammer upon contact with the object spiking massively the x/y/z axis to something rediculous like 20 30m/s. This is not HAV per se. I think the HSE wont cover any

of vibration which is frequently alleged to cause damage to structures. Unlike blasts, 000 ft lb of energy on impact. Simi larly, the maximum energy available from a double acting steam hammer is limited by the steam pressure, the area of the piston, and the stroke. On impact, the energy of the ram is imparted to the pile. It is distributed between rebound of the ram, elastic distortion

Vibration calculator. Vibration is a major topic that the power tool industry are working hard to provide solutions for, even more so since the EU Physical Agents Vibration Directive 2002/44/EC came into force. This directive deals with risks from vibration at work and has been implemented in the UK under the Control of Vibration at Work
vibratory hammers use spinning counter weights to create vibration to the pile, which allows it to cut soil into the ground. If you have ever put a nail in the wall with a hammer then you can understand how a traditional pile driver works. If you have ever used an electric knife to cut through meat than you can imagine how a vibratory hammer works. The high speed vibration causes the soil to
