Butt-end reduction units

Fully automated milling-off for rootstock


A quick look at the benefits of the unit:
  • Low operating costs with similar reduction output thanks to extremely low drive power of  15 kW
  • All units with patented safety cutter shaft
  • Optionally available reduction shaft with 22 kW drive power
  • Low electricity consumption and, notably, hardly any expensive peak period current
  • Fully automated operation of the reduction process via PLC control
  • Remote control operation with two programs and control of blank holder and ejection unit
  • The trunk can be reset multiple times and be fully debarked in so doing if need be
  • Supplied with automatic resetting device if required
  • Carrier plates for rotating the trunk with wide, non-slip contact surface including lateral protective covering
  • Long-life carrier plate drive
  • Handy chips box
  • As the chips are very short they can be immediately burned in the woodchip heating unit
  • All units supplied with switching cabinet and oil tank heating, thereby providing unrestricted operation even at sub-zero temperatures
  • Safety device, CE approval with conformity declaration


Answers to the following questions are important for us:
  • What trunk lengths will you be processing?
  • Do you wish to reset the trunk or debark it as well with the reduction unit?
  • What appliance will you be using (grapple, forklift, etc.) to place the trunk on the reduction unit?
  • Should the trunks be automatically ejected after the reduction process?
  • Is a blank holder required for your application?
  • How will the installation be set up in order to achieve the optimum working process?
  • How high should the installation be?
  • Would a conveyor for removing the bark be an advantage?
  • Will an automatic trunk feed be required for resetting?
  • Should the trunk be automatically transferred onto another machine?
  • What safety devices are required?
We determine the optimal position of the reduction shaft, the length of the machine and the equipment that is technically required on the basis of the answers to these questions. Our modular design system enables precise adaptation of the butt-end reduction unit to the requirements of your particular application.
