TNB Hydraulic Breaker
Silent and Anti-vibrqation tests have started in Japan

The noise and vibration problem of hydraulic breakers in urban areas has been closed up in recent years in respect to environmental consiousness in Japan.
Every hydraulic breaker manufacturer is intensively putting efforts to reduce the noise and vibration of hydraulic breakers. TOKU has also struggled on this issue for many years and have tested proto type units. According to our engineer's experiences, the noise and vibration issues are often comin from the same source. As a result, they have found that when the vibrqation level is reduced, the noise level is also lower than before. this discovery developed a hint in designing a breaker with less noise and vibration. The main cause of vibration and noise deveops during impact of the breaker.
A new breaker supporting system was develped by our engineers to reduce vibration and noise. Through this development, we have succeeded in lowering the noise and vibration levels for our breakers. It is a revolutionary improvement.
According to the staff that oprerate breakers, this development has reduced the vibratiion of entire machine.
*The average noise level has also improved by 10% compared to conventional breakers performed at our test site.
