Dynapac CA4000PD Single Drum Vibratory Rollers
The Dynapac CA4000PD are medium heavy vibratory soil compactors, designed for long working days in tough applications. All types of base courses and reinforcement courses can be compacted to considerable depth. The 35 mm hitch drum ensures excellent resistance to wear – even in compaction operations on rockfill. The padfoot version has it’s major range of application on cohesive material and disintegrated rock. All types of base courses and subbase courses can be compacted.
Padfoot rollers are sometimes incorrectly referred to as sheepsfoot rollers.

Your fifth generation Dynapac CA soil compactor is warmed up and ready to roll. Start compacting and the Dynapac CA roller, with Compaction Meter and Dyna@Lyzer, gives you continuous information on the increase in compaction and reveals weak areas. Compaction results are displayed on the computer screen, allowing you to focus the compaction energy on the ground surfaces that need additional compaction. The screen also displays the position of the roller in relation to a selected reference line for the section, so you always know precisely where you are.
The new CA rollers have static linear loads in steps of 5 kg/cm. This, combined with an optimum high amplitude, enables you to compact rockfill down to 1.65 meter with a Dynapac CA4000D. The better depth effect means higher volume capacity and less passes to reach compaction specifications, thus saving fuel and reducing cost. Environmental impact is also lower. If the roller is equipped with the Dynapac “Silent Weights” eccentric concept, this enhances compaction performance even further.
This feature on the new CA generation prevents damage and prolongs the lifetime of the roller by eliminating drum double jump, or over-compaction – an action that can destroy components in the machine. ABC is standard in Dynapac Compaction Meters.
The ergonomically designed, air-conditioned cabs on the new generation offer a high level of operator comfort and good visibility over the work area and surroundings. The noise level from the engine is very low. A feature unique to Dynapac CA rollers is a spin-around seat, steering module and display cluster, which allows movement of up to 180 degrees without stress to the neck or body.
Safety functions include Electronic Drive Control with a “quick brake” function, which shortens braking distances if the lever is moved very fast, and a tilt indicator. Loss of traction, even in the toughest conditions, is swiftly counteracted by an easy-touse toggling gear shifting system, or with an anti-spin system.
With Dynapac performance, you can achieve first-rate compaction results with maximum uniformity in terms of the bearing strength of each layer, with the best possible overall economy, i.e., lower cost per compacted cubic meter. Mission target reached!
The Atlas Copco Road Construction Equipment division is proud to announce that we have fulfilled our promise to offer customers soil and asphalt rollers with very low fuel consumption. The secret is our EcoMode. We closely monitored the fuel consumption of the new Dynapac soil compactor range. As a result, we can now confirm that in EcoMode, all the rollers consume 15–20% less diesel fuel than our previous range without EcoMode. RCE is one of the first manufacturers to equip its rollers with Stage IIIB/T4i engines with very low emissions. The entire range of the new CA soil compactors have engines of this type. When using the Eco-system the percentile saving is higher during compaction than during idling and transportation. Combine the 15-20% fuel savings with biodegradable hydraulic oil and very low noise levels and the result are “green” rollers. Customers who choose the traction/performance package „Anti-spin & ECO“ will have EcoMode included. EcoMode always comes with adjustable vibration frequency and a frequency meter. For Stage IV/T4f engines also Traction Control is with EcoMode.
