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.

central control unit

easy operation, exact adjustment.

Discharge housing

chipped material to the

large discharge rotor.

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.
