Height adjustment and extension of augers: Height adjustment and extension of
augers ensure optimum adaptation to a wide range of paving thicknesses and widths.
The basic configuration allows the height to be adjusted by attaching chains to the
side arms and by actuating the hydraulic screed lifting device.
When using ratchets for height adjustment (option), barrel nuts at the guide supports
in the rear wall are used to adjust the height.
Another variant allows the height to be regulated at the control panel by means of hy-
draulic cylinders (option).
Auger segments of different lengths can be attached to easily adapt to the different
paving widths.
Automatic levelling/slope control system: The slope control system (option) al-
lows the regulation of the traction point either on the LH or RH sides, by maintaining
a difference defined against the opposite side.
To determine the actual value, the two traction arms are linked with a slope control
rod.
The slope control system always operates in conjunction with the screed height ad-
justment of the opposite side.
By adjusting the height of the traction point of the arm (traction roller), the paving
height of the material or the laying height of the screed can be controlled.
Actuation occurs electro-hydraulically on both sides and can be controlled manually
by means of toggle switches or automatically (by means of an electronic grade control
system).
The screed lifting system: The screed can be lifted to transport height using the
screed lifting system. Lifting occurs electro-hydraulically on both sides by actuating
the hydraulic cylinders on the arms and is controlled by means of toggle switches on
the operating panel.
Automatic screed stop and screed charging/relieving device: The automatic
screed stop prevents the screed marks caused by a stopped screed. When the paver
finisher is stopped (during a truck change), the screed remains in floating position and
the relieving pressure is turned on, therefore, the sinking of the screed can be avoided
while stopped.
The screed relieving device puts a higher load on the chassis, thus increasing the
traction.
Activating the screed charging device can improve the compacting result under cer-
tain conditions.
Exhaust of asphalt vapours (
o
): The asphalt vapours are extracted by a hydrauli-
cally driven exhaust head mounted in the material tunnel or over the auger. The va-
pours collected are discharged together with the exhaust fumes of the internal
combustion engine.
Central lubrication unit (
o
): The central lubrication pump fitted with a large lubricant
tank supplies grease to the various lubrication circuits through various flow dividers.
They supply lubricant to the service-sensitive points of lubrication (e.g. bearings) by
adjustable intervals.
