EDITORIAL FOCUS ON ROAD CONSTRUCTION<br />
are wider than the frame, sparing<br />
customers the need for a smaller roller.<br />
Precha Wannakohn, project manager at<br />
Siripriboon Pattanakarn, says: “Dynapac<br />
machines are strong and reliable, create<br />
smooth paving and are very easy to<br />
operate. The resulting flatness due to the<br />
heavy weight of the rollers is perfect for<br />
our road projects.”<br />
From an innovation perspective,<br />
among the recent market entrants in the<br />
road-construction arena is the SD45B<br />
single-drum soil compactor from Volvo<br />
<strong>Construction</strong> Equipment. Principally<br />
designed for commercial and residential<br />
site development, utility installations,<br />
driveways, and<br />
landscaping jobs, the<br />
SD45B provides up<br />
to 12° of oscillation<br />
and 41° of frame<br />
articulation in each<br />
direction. To<br />
optimise<br />
performance, the<br />
optional Volvo<br />
strike-off blade and<br />
pad-foot shell kit<br />
further help to match<br />
the application and<br />
material type.<br />
The fully<br />
integrated traction system provides<br />
superior climbing capabilities, even on<br />
steep inclines or slippery surfaces.<br />
Furthermore, Volvo’s drum system<br />
enables the operator to achieve target<br />
density in fewer passes by combining a<br />
heavy drum weight, high amplitude<br />
(1.99mm) and high centrifugal force<br />
(93kN). When the machine is returned to<br />
neutral, the vibration system<br />
automatically shuts off, preventing overcompaction<br />
and simplifying operation.<br />
Clearly, achieving smooth passage<br />
when it comes to road-construction<br />
projects relies heavily on smart<br />
machinery choices.
