EQUIPMENT
HA90C-2 is equipped with new
screed – the JPAVER2875. This
new screed was developed by
reinforcing the rigidity of the existing
JPAVER3075. The modifications has so
far achieved high pavement precision
and usability.
Additionally, its transportation width
has been improved to 2,8 m, meeting
the target of less than a 3 m transpor-
tation width.
This screed has a variable extension
system from 2,8 m to 7,5 m and can be
further extended up to 9 m by adding
two sets of 0,75 m extension screed on
both ends.
The board operation is now hydrau-
lic-driven, leading to easier operation
and further improvement of pavement
precision. As for heating method, an
electric heating system is available in
addition to an LPG heating system.
The hopper length has been
extended by 200 mm to adjust to the
big-sized damp track commonly used
in China. The height of the hopper front
is lowered to 550 mm and the eager-
ly-awaited dial-style steering system is
available. Combinedwith lever operation,
it enables fine tuning in the pavement for
curved or narrow roads.
The operating compartment and
both sides of screed have colour moni-
tors to display more information than
ever including machine status and
maintenance intervals.
In order to minimise time, workload,
cost of preparation and clean up, the
screw has been changed to a quick-re-
lease type that covers up to 7,5 m pave-
ment while the retaining plate has been
changed to optimise this new screw.
Currently, the total length of high-
ways has exceeded 100 000 km in China
and road repair and maintenance proj-
ects are expected to play an increasingly
important role due to the increase of
traffic and the aging road infrastructures.
The newly launched HA90C-2 is
developed based on the study of the
paving operation in repair projects and is
in line with the requirements of new road
building projects. As such it achieves
maximum usability.
INTRODUCING NEW
ASPHALT PAVER
A new asphalt paver – the HA90C-2 – was introduced at
the Shanghai BAUMA 2014. This is a fully restyled model for
the world markets and is based on the HA90C which had a
JPaver3075 screed.
