The robust, clear and easy-to-maintain
Heizohack wood chipper HM 8-500 KFL is the
optimal machine for the start of professional
wood chip productions
Heizomat
suspension, spring-loaded, air
braked system taken from the
testing centre, 560/45 R 22.5 tyres
are installed. The drawbar with
variably adjustable trailer heights
is a fresh addition. The drawbar
was specially developed for the HM
8-400 KFL and is now also suitable
for other chippers.
“The robust, clear and
easy-to-maintain Heizohack
wood chipper HM 8-500 KFL
is the optimal machine for the
start of professional wood chip
production,” the manufacturer
claimed.
Innovations on the Truck
Chipper HM 14-860 KL
Wood waste such as slats,
edged pieces, pieces of wood,
rinds, branches but also whole tree
trunks can easily be processed into
high-quality wood chips with a feed
width of more than 700 mm and a
pull-in height of 800 mm. Whole
trees can be processed up to a
diameter of about 500 mm.
Powered by a 10-groove V-belt
countershaft, two power bands
transmit power to the chipping
rotor. The rotor is equipped with
eight quick-release blades. Built-in
special sieves ensure nearly slither-
free and homogeneous wood chips.
Thanks to the large flywheel in the
throwing fan, the machine can be
operated with little effort, saving
fuel and making it tractor-friendly.
The proven control unit
HE002 is used as load and intake
control. All other machine control
units are also simple and like
all Heizohack assemblies, are
solidly constructed. A smooth but
aggressive in-feed is ensured by
the large upper feed roller, the
powerful intake chain conveyor
and the hydraulically driven feed
roller, upstream of the infeed
chute. An intake chain integrated
in the infeed chute is available as
an option.
The wear plates installed in the
machine are available both in a
Hardox version and as an armoured
version. With the 40km/h
The HM 14-860 KL truck chipper,
introduced two years ago, has seen
several improvements. The original
carrier and drive vehicle Mercedes
Benz Arocs, is now being replaced
by the more powerful Arocs 3353
AK, 6x6 with an output of 530 hp
(390 kW). Of course, this engine
also fulfils the Euro 6 emissions
standard.
The slightly longer wheelbase
now allows the installation of a
larger (500 litre) diesel tank and
can also take the capacity of the
hydraulic oil tank, which has
been increased to 500 litres. As
an innovation, two hydraulic oil
pumps are now being installed,
which enable separate supply of
the assembled loading crane and
the oil circuit for the wood chipper
via two separate oil circuits.
Also new is the installation of
a robust safety glass pane from
Kasiglas. The modified glass
panel offers the operator the best
possible protection and improved
all-round visibility. Additional to
the four LED headlamps on the
driver’s cab, a new completely over-
routed lighting package will now be
installed on the outside of the truck
cab. A light bar with 22,300 lumens
on the cab front and a light bar
with 3,300 lumens on the side of
the cab rear wall ensure excellent
illumination of the workplace. Two
yellow front strobes integrated in
the grille and a yellow warning light
on the driver’s cab make it possible
to secure the danger spots around
the vehicle.
The Ringfeder automatic
towing hitch now has a 40 mm bolt
diameter, and the two double-
acting hydraulic connections at the
rear of the vehicle can now be used
while driving, if required.
As an option, the wood chipper
can be equipped with a 700 mm
telescopic ejection tower and the
fan of the truck engine can also
be equipped with reversible fan
blades on request. The fan blades
are automatically turned and
clean the radiators by reversing
the air flow. This fan system saves
the need to frequently clean the
filter pack whilst also reducing
fuel consumption, since the
truck engine operates at its ideal
operating temperature.
