In tandem

Dynapac has introduced four tandem asphalt compaction rollers for quality asphalt finish, efficiency in operation and ease of service.
A new 8-10-ton-class tandem asphalt roller, the CC224HF, and a split-drum version, the CC234HF, together with 10-12-ton models CC324HF and split-drum version CC334HF are designed to meet the needs of contractors, road contractors and rental companies worldwide.
The new rollers have been designed to achieve high-quality surface finishes offering operational features such as “soft” starting and stopping to prevent bowing or cracking in the asphalt layers, allowing even unskilled roller operators to start and stop without leaving marks.
As a safety feature, the machine will drop out of the soft mode and brake immediately if the lever is moved quickly, signaling the need for an emergency stop.
New features simplify and speed servicing to guarantee maximum availability. Use of a double-pump vibration system, for example, eliminates the need for a vibration valve, making the system more efficient, aiding servicing and reducing fuel consumption.
