en.Wedoany.com Reported - At the 2026 ConExpo in Las Vegas, Sweden's Dynapac showcased the CC7000 VI, a 32,000-pound (approximately 16-ton) double-drum vibratory asphalt compactor. This model features large-diameter 55-inch wide drums with a static linear load of 211 pounds per inch. By integrating the patented "Efficiency Eccentrics" mechanism, the machine reduces the energy required for startup by 50%, marking the Swedish company's official return to the 16-ton heavy-duty asphalt compaction market.
As a leading global manufacturer of road construction machinery, Dynapac incorporated large-diameter drum technology, originally developed for soil and asphalt compactors, into the design of the new CC7000 VI. The equipment is equipped with "Seismic Asphalt" technology, currently the only system on the market that automatically aligns vibration frequency with the asphalt layer's natural frequency. Its core logic utilizes infrared sensors to collect data five times per second, monitoring material stiffness and temperature in real-time, enabling automatic switching to the optimal vibration frequency without operator intervention.
Test data shows that this frequency-adaptive technology delivers more uniform compaction and reduces fuel consumption by up to 25%. By minimizing unnecessary vibration impacts, wear rates on the eccentric drive system, drum shells, and hydraulic components are reduced, extending the equipment's average service life by 25% compared to traditional models. Furthermore, the system significantly improves the cabin's acoustic environment, transmitting less noise and physical vibration to the operator.
The CC7000 VI's cabin features a rotating and sliding seat, with the control terminal and display moving in sync with the operator's posture. It is equipped with a high-capacity water tank to reduce the frequency of refilling stops. The model is now officially available through Dynapac's global distribution network. In the context of increasingly stringent requirements for construction precision and energy efficiency in large-scale infrastructure projects, the CC7000 VI asphalt roller, through its fully automatic frequency adjustment solution, reduces reliance on skilled operators and directly shortens delivery timelines for high-grade pavements such as highways.
