When it comes to the precision and
cost-efficient construction of concrete
pavements and monolithic profiles,
Wirtgen’s slipform pavers are right for
the job. With their modular design, the
machines can be configured as needed,
and virtually all conceivable structures are
possible, including special shapes. The
SP 64i represented the new generation
of slipform pavers at CONEXPO CON/AGG
2017 in Las Vegas.
The SP 60 series replaces the successful
SP 500 – and is said to open up new
possibilities for contractors. More features
than ever operate hydraulically in the SP 60
series. Thanks to a new hydraulic concept,
energy is now used much more efficiently,
making it available for new equipment
options, for example, trimmers and a large
delivery screw for offset applications, or
the four swivel arms used to switch the
machine from transport to working mode
faster. The system starts as a basic version,
and grows along with the number of modular
equipment options selected. Customers save
by choosing only the options they want.
Likewise, the intelligent machine control
systems in Wirtgen’s slipform pavers are
state-of-the-art. Interfaces for the Wirtgen

Complete with new oscillation technology,
the DD105 OSC double drum compactor
from Volvo Construction Equipment has the
ability to effectively compact in delicate
areas, such as bridges, over pipes and
close to residential areas.
Fitted with the flexibility of Volvo’s
oscillation technology, which eliminates
vertical vibrations, the DD105 OSC offers
high compaction performance while
producing a non-damaging oscillation
movement. Featuring a 1 680 mm wide
drum with hardened, abrasion-resistant
alloy steel drum shell, the DD105 OSC is
powered by a D3.8 Volvo engine.
In addition to the oscillation technology,
adapting to different jobsites is easy. With
the option of using a drum with eight
amplitude settings or two, changes can
be made according to the surroundings
and material depth, adding further to
the machine’s versatility. Selecting the
amplitude most suitable for the mix
conditions and thickness enables the
operator to reach a higher quality of work
in fewer passes.
The DD105 OSC offers features that are
designed with the operator in mind. The
open ROPS/FOPS canopy and the optional
enclosed cab combine comfort, control and
visibility, ensuring a productive operator
environment. From the air suspension seat,
the operator has a commanding view of the
jobsite, as well as clear sightlines down
to the drum and spray bars, enhancing
safety and rolling precision. The view of
curbs and obstructions is enhanced with
off-set steering, aiding precise compaction.
With ergonomically-positioned controls
and joystick, manoeuvrability is improved
for the operator, who can rely on the Anti-
Slip Control to easily load and unload the
machine without damaging the pavement.

WITOS FleetView systems support users,
as does the optional Paving Plus package.
Combined with this package, the swivel
arms can actively circumnavigate obstacles
during the concrete paving process.
The option of hydraulic rotational drives,
available for all SP 60 series models,
provides even better manoeuvrability.
With hydraulic rotational drives, the 90° or
120° steering angle of the crawler tracks
becomes a major advantage, for example
when setting up the machine at a job site.
Another new development is the option
of choosing between two undercarriage
sizes. Why is such an option necessary?
For professional concrete paving at job
sites with unpaved ground, the lanes for
the pavers must be stabilised ahead of
time. However, the larger crawler tracks
exert less contact pressure per unit area,
reducing the pressure on the ground, thus
giving the slipform paver the stability it
needs. This in turn has a positive impact
on the quality of the paving results.

The SP 60 series, launched at ConExpo 2017,
replaces the successful SP 500.
The new DD105 OSC is ideal for working in delicate areas, such as bridges, over pipes and close
to residential areas.
