How AVT works

The benchmark in vibration reduction Makita demolition tools are among the best in the world. Working with the users to solve the problem of vibration Makita’s AVT products have been designed in close relation to users needs at site level.

Focusing on the three D’s: Dialogue, Development & Delivery

No effort has been spared to ensure that our products provide the professional user with reliable, long lasting power. The diagram on the left shows the benefits of AVT at work and how we have managed to apply this revolutionary new technology to two of our most heavy duty hand held tools.

Initial Protection

The AVT mechanism works by transfering air around a series of chambers which, in turn, pushes a counterbalance in the opposite direction to the piston, thereby cancelling out the vibration the piston would have created otherwise.

Secondary Protection

Shock absorbing handles are also used on appropriate tools for added protection.

Anti Vibration Handle

As the handle receives vibration from the motor housing the handle is shifted in all directions with the help of the ball joint functioning as a fulcrum, the rubber dampers soak up this movement, lowering the vibration transferred to the operator.

Anti Vibration Side Grip

As the anti vibration grip receives movement from the machine through the shaft the vibrations are dissipated with help of a ball joint functioning as the fulcrum. The rubber damper between GRIP and SHAFT absorbs the vibration from the ball joint.

1. Vibration damping

AVT, Anti-vibration technology uses the principal of counterbalances to massively reduce the harmful vibrations experienced when using hammers drills and breakers.

2. Motor speed

Suppressing the motor speed reduces vibration of tool body when idling and decreases the amount of vibration to operator’s hands during a day’s operation.
