RKN 806 and RKN 806 XRS - 2H Butt end reducer

The but end reducer is a single-purpose machine for placement in technological lines for wood processing and is a machine used to reduce the root run-up from the rhizome part of the trunk. The reducer has one or two reduction cutters (XRS - 2H version) - left and right. When the cutout passes through the reducer, the reduction cutter is activated - depending on the orientation of the cutout. Correct cut-out entry and feeding is carried out on the preceding technological device.

The machine frame is welded from quality steel plates and profiles. The machine is designed for the most demanding operation with emphasis on durability and reliability.

The log is rolled into the reducer from the previous technological equipment properly started. It is then pressed into the bottom line by a hydraulically operated pressure arm. The pressure arm is equipped with driven chains for rotating the cut-out.

The reduction head, mounted with the driving hydraulic motor swinging on the arm, from the bottom of the machine, is raised to the working - reducing - position by a hydraulic cylinder.

The log pressed by the upper arm is rotated by the rotation chains. The spinning reduction head is raised from its lower position to the working position and the root rake is reduced. When the root run-up has been reduced, the reduction head is lowered to its lower position. The upper pressure arm is raised to its upper position and the ejection segments in the frame eject the reduced cutout from the reducer. In the two-head reducer design (XRS - 2H), the measuring frame located in the technology in front of the machine determines which side is to be reduced. The reduction cycle is controlled by the control system and is automatic. Manual input into the process is possible and must not compromise the safety of the machine and the operator.

The rotation of the trunks is ensured by an electric gearbox with transmission to the rotating segments.

The machine is designed to be used in a line - the supply of cuttings for reduction and the removal of reduced cuttings and shavings is handled by downstream machinery.

The hydraulic unit is not included in the machine delivery.

The electrical distributor and control system are included in the delivery.

The machine is approved by the State Testing Institute and fully complies with current EU regulations.
