Volvo introduces new high-frequency compactor
DD128C model improves productivity with fast rolling speeds and high drum vibration frequencies
Volvo Construction Equipment has launched a new asphalt compactor which offers higher productivity with what the Swedish equipment giant says is the fastest rolling speeds and highest frequency in the industry.
A statement from Volvo CE said the new DD128C compactor maintains proper impact spacing to provide the most productive rolling train available and features a 2000mm drum width with chamfer and radii drum edges for high compaction performance and reliability. The machine also features a large 1400mm diameter drum and auto-reversing eccentrics – an automatic function that ensures eccentric rotation in the direction the machine is traveling – for smoothness. It is also equipped with an advanced automatic drum wetting system that provides speed-dependent water flow to minimise water usage and ensures uniform drum coverage to prevent material pick-up.
“The DD128C is our best compactor yet,” said Chad Fluent, global product manager – Compactors. “This is the most productive, fuel-efficient, and versatile machine we offer.”
Offering Volvo’s exclusive eight amplitude eccentric system, the DD128C has a wide range of amplitudes, from 0.08 to 0.8mm. This allows for high versatility whether the job is an ultra-thin lift or a deep 10cm lift. Utilising Volvo’s patented technology to detect the amplitude setting, vibration frequency is automatically adjusted to the highest vibrations-per-minute available for the amplitude setting – so operators can get the highest rolling speeds and best productivity without compromise.
The DD128C is powered by a 148hp Volvo D4 engine, which delivers high torque at low rpm, ensuring performance with minimal noise and fuel consumption. Engine operating speed during work mode is a low 1850rpm, providing the torque and power needed without the noise and fuel draw. Fuel efficiency is further enhanced with optional auto-idling and auto-engine shutdown features. The engine and hydraulics are designed to work together to provide quick eccentric start times and exceptional drum performance in the most demanding conditions.
