The German manufacturer of
biomass heating systems and
woodchippers Heizomat, has
presented an entirely new product,
the ‘Heizotruck ‘, which among
other things is designed to move
and power large mobile wood
chippers.
The Heizotruck is based on the
twin-axle all-wheel drive chassis of
the Mercedes-Benz Arocs 2051 4x4.
It is powered by a 510 HP engine.
The forestry version of the
Heizotruck has the same modified
user-friendly cab, with separate
swivel seat and clear view rear
window as the conventional
Chippertruck from Heizomat.
All necessary controls for the
operation of a wood chipper are
already integrated into the cab.
The agricultural version of
Heizotruck, however, is equipped
with a large panoramic view
rear window in the cab. In both
versions, the rear PTO is driven
by the NMV-drive (direct full
engine power drive from the main
gearbox).
Due to the especially developed
PTO drive there is a maximum
torque of 3,800 Nm available on
the mechanical PTO shaft. At an
engine speed of 1,550 rpm a PTO
speed of 1,000 rpm can be achieved
at the rear PTO.
This means that large power
output can be obtained from the
truck with low fuel consumption.
The Load Sensing hydraulic system
has a pump with an output of up
to 250 litres/minute. The hydraulic
outlet connections are mounted
behind the driver’s cab as well as at
the rear of the Heizotruck.
In addition, there are five
double-acting (DA) outlets at the
rear, three DA outlets behind the
driver’s cab as well as three DA
outlets at the front mounting plate.
The optional fifth wheel enables
connection of standard fifth-wheel
trailers. As a result this tractor
unit has many uses, e.g. for the
transportation of wood chips, for
the maize harvest, etc.
The Heizotruck and the high-
speed tandem axle wood chipper
Heizohack HM 14-860 KTL fit
perfectly together. This is a large
26 in, 650mm diameter capacity
chipper which fits perfectly behind
the Heizotruck having excellent
power and torque for efficient
chipping.
Depending on the set up of the
chipper, the wood chips produced
are suitable for all heating systems
of private customers as well as
for large commercial installations
through to power generating
stations.
Due to the high output capacity
of the LS hydraulic pump of the
Heizotruck, the timber crane M80
F101 from Epsilon can also be used
with maximum efficiency.
The crane is still mounted on
the wood chipper, as with previous
versions. The operator’s distance
from the truck cab to the in-feed
hopper of the chipper slightly
increases compared with a chipper
driven by a tractor or a chipper
which is firmly mounted on a
truck. However, this gives a greater
working range for the crane, which
in turn means less moving along a
stack of timber.
For the crane-feed, a telescopic
extension chute is available. The
end piece of the chute can be
extended hydraulically by 700
mm. This leads to better and more
precise filling of trailers, containers
and skips. With the special flap,
which can mounted to the end flap
of the chute, it is now possible to
blow woodchips horizontally into
lower buildings and chip stores etc.
The chipper HM 14-860 KTL
is one of the larger drum wood
chippers with an infeed width
of 1,215 mm and a maximum
opening height of the upper infeed
roller of 800 mm. End pieces to
a maximum of 800 mm can be
processed. Larger diameters can be
split previously. Therefore a cone
splitter with three motors can be
fixed to the draw bar if required.
The rotor diameter is 690 mm.
Whole tree trunks with a diameter
of up to 650 mm can be chipped
easily. With the innovative multiple
blade holder system, either quick
change wear blades or chipper
knives can be attached. For hard
wood from a diameter of 400 mm,
Heizomat recommends the use of
chipper knives for this rotor type.
The diameter of the upper
in-feed roller is 800 mm. This large
diameter and heavy weight in-feed
roller makes easy work when
feeding all types of new and waste
timber into the chipper.
Due to the arrangement of
the 14 blades placed on rotor (or
alternatively also the chipper
knives), which spread over the
entire feed width, Heizomat
ensures a reduction of the power
