Low operational costs as well as
high quality paving and compac-
tion results are fundamental to
customers and end-users realising
sustainable productivity, lowest overall cost
of equipment ownership and ultimately
profitability. Quality equipment that delivers
powerful, reliable and efficient performance,
is safe and operator friendly, requires little
maintenance, has long service intervals and is
easy to service are central to achieving these
objectives. “The Dynapac range of asphalt
pavers and rollers and Chicago Pneumatic
compaction equipment deliver on all fronts,”
says Neville Marthinussen, Atlas Copco
Construction Technique business
line manager, Dynapac road construc-
tion Equipment.
The newly launched Dynapac SD2500 PLC
(Programmable Logic Control) large tracked
and wheeled paver line which complements
the well-known, proven F1700 and F2500
electric range is designed and engineered
to take paving quality, which is measured
in ride-ability, compaction, evenness and
profile, to new heights. The SD2500’s host of
features, including an intelligent logic control
system and an efficient and powerful drive
system, are focused on high performance
screed, smooth material flow, efficiency,
ergonomics and low main-
tenance and service.
“In addition, the SD2500 features a unique
safe impact system that absorbs the impact
during truck docking and eliminates segre-
gation of material on the asphalt mat, and
further improves asphalt finish and therefore
ride-ability and unwanted marks on the
surface,” states Marthinussen. “The system
which consists of a hydraulic anti-shock push
roller also extends the docking length to give
flexibility when working with different truck
models,” he adds.
Optimising work flow
When it comes to screed stability, Dynapac’s
patented four-guiding tube principle delivers
unmatched results. Marthinussen explains
that as no supporting rods are required for
the screed which reduce start-up paving time
and increase available productive hours,
particularly during limited available working
time either due to inclement weather and/or
access to road due to traffic requirements. All
Dynapac screeds are free floating, ensuring
excellent paving results.
Another excellent feature of the SD2500
range which optimises work flow is Pave-
Manager 2.0. This intelligent control system
monitors the complete paving process and
include pave parameters, pave memory func-
tion and automatic crown and slope settings.
Marthinussen also points out that paving
programmes can be conveniently set from
outside the machine through the PLC.
The SD2500’s optimised, longer hopper has
a very low dump height for fast and easy
material transfer from trucks and ensures
improved paving quality. The machine’s
slim gearbox and enlarged feeder tunnel
allow homogeneity of mixture, despite the
high material throughput of up to 1100 tons
per hour.
With operator comfort always a top
priority, the SD2500’s new platform suits all
needs from the operator’s perspective to
ensure safe, comfortable operation. Excellent
in-cab design features and low noise levels
presents an ergonomic high-end workplace
that gives the operator a full overview of the
complete working situation at all times.
Performance
Powered by a Cummins QSB6.7 diesel engine
with emission stage IIIA or stage IIIB, the
SD2500 machines require little and simple
maintenance; the centrally located service
points and components are direct, easy and
rapidly accessible from the ground without
any height adjustment required from the
service technician, saving time and money.
The maintenance process is further simplified
by the large number of high quality plug-and-
play components.
When it comes to performance, appli-
cation, compaction and operator control as
well as maintenance and service, Dynapac’s
tandem asphalt rollers are designed with
across-the-board built-in quality and effi-
ciency. The machine’s numerous
