PRoDuCtion of WooD CHiPs
Whenever the efficient production of high-quality
wood chips is required, Doppstadt precision chip-
pers of the DH series are always the first choice.
A full-steel chipping drum rotates mounted in
robust steel frames. The special arrangement of
the chipping knives guarantees a low-vibration
with all kinds of wood and an optimum structure
of the chips.
The whole unit is driven by a powerful Mercedes-
Benz engine with high efficiency. The capacity is
Road transport of the DH 910
Processing logs with the DH 910
Moving the machine
The precision chippers of the DH series process waste wood,
log and root timber producing different sizes of wood chips
which can be adjusted by choosing different feeding speeds
or by changing the screening segments.
Mounted on multi-axle trailer chassis, semitrailers or on
tracks, equipped with powerful and economic diesel engines,
they meet all requirements.

designed to cope with the demands of continuous
service.
Reliable components manufacturerd by major
suppliers of hydraulic systems, controls and safety
systems on the basis of a thought-out construc-
tion guarantee very quick maintenance and short
downtimes during operation.
The great number of options for operation, adjust-
ment and equipment permits to meet any demand
on the final product and the economic efficiency.

Discharge arm
short setup times and flexibility
thanks to the hydraulically foldable
and slewable discharge arm.
Drive v-belt drives of the chipping rotor.
central control unit
easy operation, exact adjustment.
Discharge housing
screw transport of the
chipped material to the
large discharge rotor.
remote control
easy operation – e.g. by wheel
loader operator, exact ad-
justment and reading of the
machine data by multifunction
display. machine operation by
18-channel remote control*.
maintenance
large doors for
optimal maintenance.
FeeD-in roller anD chain Floor
the large feed-in roller and the
aggressive apron feeder guarantee
the in-feed of all kinds and shapes
of wood without difficulty.
chipping Drum anD knives
the full-steel chipping rotor chips the
materials. the rigid cutter bar and the
re-shredding screen guarantee a homo-
geneous product. the wood chip sizes
can be determined by choosing different
feeding speeds or by changing the
screening segments.
slip-on coupling
By means of the slip-on coupling
the machine can be moved by
the wheel loader grab (only for
machines with drawbar).
in-FeeD extension
the foldable in-feed extension
permits the loading and positioning
even of long pieces to be chipped.

swing-out cooler with reversiBle Fan wheel
the swing-out cooler is easily
accessible and self-cleaning by
means of a reversible large fan
wheel. the low speed keeps the
noise level down.
