Cutting section: The cutting section consists of the mechanical milling drum drive,
the milling drum housing, the milling drum, the moldboard, the sliding shoe and the
side boards.
All these elements are precisely tuned to one another and their designs adapted so
that high performance milling is assured with low levels of cutting tool wear, as is very
good retrieval, granulation and transport of the milled product, an exact milling pattern
with cleaner milling edges is produced and the processed area is kept clean and free
of milling product which has not been retrieved.
- The mechanical milling drum
is driven by the diesel engine via a hydraulic separating clutch, belt pulleys and a 14-
belt powered-belt pack on a planetary gear directly connected with the drum body.
This guarantees a low-loss transfer of power, intercepts load impact and has a long
service life. The drive is fitted with an automatic belt tensioning fixture. The hydrauli-
cally selectable 3-pulley dry-plate clutch and the two-stage planetary gear are config-
ured specially for the milling drum drives and finely tuned to the engine rating of the
machine.
- The milling drum
rotates in the opposite direction to the machine forward drive. The professional cut-
ting tool arrangement and equipping with the best cutting tools ensures rapid and
clean cutting as well as high cutting tool downtimes.
A good, tried and tested, new type of changeable fixing system is used on the stan-
dard drum (line spacing 15 mm, milling width 2010 mm (PL 2000 S) / 2100 mm (PL
2100 S)). Thanks to the manner in which it is able to rapidly and simply replace upper
fixing parts, it makes minimum change times possible and does not therefore cause
long downtimes during replacement.
The milling drum housing
seals off the milling drums to the left and right through the side boards, the sliding
shoe to the front, the moldboard to the rear, in all grading depths and therefore en-
sures optimum material pickup and a clean cutting surface.
The side plates are fitted with replaceable, zero-wear hard metal plates to increase
their service life.
