2. Root reducer

Dimensions:
Length: approx. 7 m

Description:
- 3 driven chain beds, drive chain: roller chain 6/4" with square tooth attachment
- Drive via gear motor
- 2 support blocks with non-driven rollers (roller bearing)
- hydraulically pivoting clamping device for clamping from above with V-bed
- Drive chain: roller chain 6/4", drive via gear motor;
- housing-mounted milling shaft with reversible, interchangeable knife blocks
(4 cutting edges per knife block), drive via three-phase motor
(drive power: 75 kW; flexible tire coupling)

- automatic switchover during the reduction process)
- Milling shaft length: 1,200 mm, mounted on a rotatably supported, adjustable
drive rocker (hydraulic drive)
- 4-arm lifting device, hydraulically driven
- integrated hydraulic unit (15 kW)
- integrated log diameter measurement for automatic milling time calculation
(control unit included in item 2), for wood lengths under 3.5 m, the
Kodpfxozcaqtj Ap Djdu
support position of the log must be adjusted (reduced reduction length)
Reduction length for log length of 2.7 m: 0.7 m, for log length of 3 m: 0.9 m

3. Control system
