Dynapac CC4200 Asphalt Double Drum Roller
The Dynapac CC4200 has a rolling width of 1730mm.
Dynapac tandem rollers are designed with efficiency in mind – application efficiency, operator efficiency, compaction control efficiency and service efficiency. Performance, visibility,
operators comfort, compaction control and serviceability for the CC line will appeal to owners, operators and service crews. The environmental benefits appeal to everyone.
All models have high frequency vibration as standard.
With the Dynapac rollers you achieve high quality surface finishes through operational features such as soft starting and stopping to prevent unevenness or cracking in the asphalt layers. This allows even an unskilled operator to start and stop without leaving marks. In a panic situation, the machine will drop out of the soft mode and brake immediately, signalling the need for an emergency stop.
There is a number of features to the CC rollers to make servicing quick and easy, ensuring maximum uptime. The use of a double pump vibration system eliminates the need for a vibration valve, making the system more efficient, aiding servicing and reducing fuel consumption. Both pumps – one for the front drum and one for the rear – can simply be shut off. With a volume of 750 litres for the CC2200 – CC3300, 900 liters for CC4200 and as much as 1400 liters as an option for for CC5200 – 6200, it gives ample water resources.
One way of achieving high quality compaction is to optimise the ergonomics, ensuring that operators have continuous visibility of the operation and comfortable access to the controls. The corrosion-free water tank is mounted in the front frame. This helps the rollers feature 1 x 1 metre view and full visibility of all working functions. You can tailor your roller to local conditions, including operator´s platform with ROPS, ROPS cab, aircondition etc.
The clear LCD control panel gives operators the information they need. All the gauges are displayed and the operator can change between menus at the touch of a button.
With high frequency/low amplitude for thin layers and high amplitude for thick layers the machines are versatile and will efficiently compact any type of asphalt mix. Thin layers with high stone content cool off quickly and need to be compacted fast, but use of a high amplitude risks crushing the aggregate. Dynapac recommends a high frequency and lower amplitude.
All machines can be equipped with the optional offset drum (split drum and combi rollers have off-set as standard.) This in combination with the asymmetric cab make the machines very easy to operate.
The new models are powered by Cummins QSB 3.3, QSB 4.5 or Deutz TCD3.6. Both Stage IIIA/T3 and Stage IIIB/T4i versions are available. Dynapac’s automatic engine idling system together with a highly efficient hydraulic system makes fuel consumption low and efficient. Infinite adjustable maximum speed is standard.
We have equipped the machines with slideable and turnable seat and steering module for best ergonomics. The engine is placed on the rear module with less heat and noise for the operator. The very low vibration level on the operator´s platform also adds to the comfort of the operator.
Environmental benefits are achieved through reduced fuel consumption and quieter operation. Efficiency enhancements have saved some 8 kW in the operation of a typical model in the range, with consequent improvements in the running costs and noise. Optional EcoMode with fuel savings up to 15 % is also available. It also makes the already quiet CC roller even more silent. Biodegradable hydraulic fluid is optional. The automatic idling system keep exhaust emission on a low level. Emission controlled engines are standard.
Daily service points are few and easily accessible. The position of the engine on the rear module and the large, easy to-open engine hoods contribute to easy and fast service. The service info displayed directly on the drivers LCD also faciliates service jobs. With lubrication free steering hitch and steering cylinder, very few grease nipples are found on these machines. At the same time, the periods between servicing have been extended. Corrosion-free water tank and sprinkler tubes, in combination with easily accessible filters, ensure reliability and easy maintenance. Hydraulic hoses can be replaced in individual segments, avoiding the need to fit a full length. Drum shock absorbers also benefit from easy replacement – there is no need to remove the forks or the drums.
