The cutting system is characterized by the closed drum, which, supported by the interchangeable calibration grid, allows to obtain a uniform and homogeneous wood chip, even for domestic boilers.
The machines of the PTH 30.70 series can be fed manually or by mechanical means, or by mixed solutions. For those users operating exclusively with manual loading, the chipper is equipped with a robust safety bar and a state-of-the-art push-button panel to ensure an intuitive and safe managing of the machine by the operator, present by the machine board.
Thanks to the large hopper, the chipper can also be fed by means of a forestry grapple: in this case the supply includes a special remote control.
A specific set-up is also available for those who use either the manual and the automatic loading mode: the machine is equipped with a safety bar and push-button panel that can be excluded when feeding with external mechanical means.
The main wear parts are specially designed to be low cost and allow easy replacement. The exhaust fan, for example, is equipped with interchangeable internal volutes and thus allows the extension of the life of the wood chip expulsion system without machine standstill.
