drum and rear wheels will maintain contact
with the ground through the full 10 degree os-
cillation even through a full turn. Combine the
new articulation joint with traction control and
the 3000 Series machines have gradeability
that is unmatched in the industry.
A further enhancement on the HAMM 3000
Series, is the Hammtronic technology, devel-
oped by HAMM to provide an optimum com-
paction operation. Its function is to manage all
engine and roller functions. The drive, vibra-
tion, oscillation and engine speed are all con-
trolled by Hammtronic. The rolling speed and
vibration system are adjusted with electronic
engine management, maximising operating
performance. Information is transmitted to the
information display and documents the most
current data. Hammtronic automatically mon-
itors the front and rear drives preventing spin-
ning of the drum or wheels further enhancing
gradeability. Power on demand technology
greatly reduces fuel consumption by as much
as 30 to 50%.
Power for the 3000 Series is a Deutz water
cooled diesel engine that incorporates an
innovative cooling system which allows the
engine to run at optimum levels and provides
a lower fuel consumption rate than competi-
tive models. All models are available in either
smooth drum or pad foot configurations. The
compact tandem roller market is one of the
most competitive market segments world-
wide. HAMM has dominated this market in
most countries with their HD Compactline
which now sits at a model range of 16 units.
This places HAMM at the top of the market
segment with the largest model range in the
sub 4.5 ton weight category. Of the 16 unit
model range, four models are equipped with
Oscillation technology having one vibratory
drum and one oscillating drum. The balance
of the range is equipped with either a single
vibratory drum or both vibratory drums.
The advantage of Oscillation is that it achieves
a rapid increase in compaction because the
oscillation drum directs tangential thrusting
forces into the material to be compacted
while remaining constantly in contact with the
ground. The combination of continuously act-
ing static load and changing dynamic shear
forces in the material brings about a faster,
better and more gentle compaction.
The design characteristics attributed to the
HD Compactline ensure that its features con-
tribute to the efficient operation of the equip-
ment and the comfort and safety of the driver.
The HD Compactline rollers offer the operator
unrestricted view of the drum edges and the
working environment in front, behind and both
sides of the unit.
The HD Compactline, by virtue of its compact
construction can work nearly everywhere es-
pecially with their low profile can be ideally
used in areas with low ceiling heights. The
optional fold away ROPS makes the unit even
smaller for ease of transport. The three-point
articulation joint is not restricted to the larger
units only, for the HD Compactline range has
very much driving comfort in mind, thanks to
the three-point articulation joint and flexible
positioning of the driver’s seat. The articulat-
ed joint effectively acts as a shock absorber
and provides excellent directional stability,
good stability in turns and a high degree
of stability against overturning. Driver com-
fort is further enhanced by the driver seat,
steering column, lever and footplate being
mechanically isolated from the frame. This
significantly reduces the amount of vibration
experienced by the driver.
All HD Compactline rollers offer extremely
high levels of side clearance with drums that
can be operated in offset position (50 mm
in machine models upwards of 2.5 ton) in
crab steering mode. This allows for compac-
tion right up to the edge, allowing for perfect
compaction even on narrow lanes and along
curbs. Controls and instrumentation for the
HD Compactline is language-neutral and can
be mastered in merely a few minutes. The
clear unambiguous markings of the control
panel make operation virtually intuitive.
Power for the HD Compactline range is by
means of Kubota water cooled diesel engines
either the 3 cylinder or 4 cylinder depending
on the model and the territory where they will
be operating. Low noise levels and safe oper-
ating has been the hallmark of these engines.
The HD Compactline offers a tangible ad-
vantage and one particularly valued by the
majority of rental companies because they
are compact, efficient and particularly easy
to operate.
