  • Performance

    • 70% of breaker impact energy is generated from nitrogen gas pressure in the cushion chamber, the remaining 30% of energy is created from the operation oil circuit.
    • Cushion chamber allows every blow to be isolated from the carrier and operator, recycling and generating energy for the the next operation.
    • The long stroke piston enables a more powerful impact energy while increasing stability when recoiling.
    • The 50/50 piston to tool weight ratio efficiently transfers blow energy into the material to reduce recoil.


    • Dust preventing valve ensures that the cleaner air from the upper part of the breaker is recycled through the impact chamber and blows dusty air to the bottom.
    • Using a low pressure nitrogen charge, Toku breakers help cushion every blow, reducing wear and tear and providing operator comfort.
    • Dust preventing valve can also be used for underwater applications to lead high pressure air from an air compressor.
    • With an innovative side plate and bracket system Toku breakers can be powered by a wide variety of manufacturers and equipment, from skid steer loaders to compact excavators.
