FAQ
ATVA™ can be used on all vibrating machines working with high frequency impacting (“hitting”) movements. In other words, machines like rock drills/hammers, chiselling machines, stampers, concrete vibrators, tiger saws, compactors, hammer drills etc. are suitable for use with ATVA™. Below, a screenshot from one presentation from the ZeroVib project, indicating machines where vibrations can be substantially reduced with the new methods developed in the project.

Problems with rotating machines (dental drill, nut tightener, nut counter-force etc) are reduced with a different technology developed by the RISE ZeroVib department, for these applications ATVA™ is not applicable.
The ATVA™ technology is applicable for reducing vibration on machines with an reciprocating/impacting vibration with a fundamental frequency exceeding 1 Hz.
The ATVA™ equipped machines that are in use are available standard machines that have been stripped down and equipped with ATVA™ Unit as well as with other specially designed components. The company that built these prototypes, TM Verkstad AB, can produce identical prototype machines but these machines are not optimal in all aspects, and they are more expensive than machines produced by dedicated machine manufacturers. But still, these prototype machines are the machines widely preferred by the quarries that use them – they give 80-90% lower vibrations, their weight is reduced by 50% and the efficiency is better.
The objective from the ATVA™ Licence Group is to get started with well-established manufacturers that can redesign machines to fit with an ATVA™ unit, thus making a machine with an optimal balance of all technical, practical, ergonomic, economical etc features. The two quarry companies that have bought the patent rights and created the ATVA™ Licence Group will be the first customers – it is a part of the licence contract proposal.
Vibrations are not only a health problem – vibrations from drills that are held by excavators or robots are transmitted into these machines and causing problems that they in their turn are not designed to withstand. The RISE research team is convinced that, within a few years, ATVA™ will be a standard for such application, as excavators or robots will be exposed to far less damaging vibration.
So far, the only application with an ATVA™ equipped robot is at the Ävja Quarry, but as the CEO has stated in his interview, it would not have been possible to robotize the flaming and chiseling robot without the ATVA™ technology.
