Dynapac CA255 is designed for long working hours at tough applications and offers unparalleled compaction performance. It is utilised for compaction of most types of soil. Road building, airfields, harbours and industrial sites are typical applications of this equipment. All types of base courses ad reinforcement course can be compacted to considerable depth.

This soil compactor offers many other features such as:

• Best-in-class heavy-duty steering hitch avoid excess wear
• Informative operator control and improved ergonomics
• Advanced hydraulic system ensures high efficiency due to closed loop hydraulic circuit and low hydraulic tank volume of 52 litre

Atlas Copco offers soil compactors from 4 tonne class to 27 tonne class. Dynapac CA255 is designed for high productivity in the toughest conditions and has several unique features.

Easy maintenance
This soil compactor is designed to simplify and facilitate maintenance and periodic service. The engine dipstick, oil-filler cap, oil fuel filter, air filter and radiator-level control are all easily reachable ensuring ease of serviceability.

Analyse instead of guessing
In all projects, it is vital to do the right thing and to do the things right. The compaction meter is the basic tool to meet the compaction requirement. It displays the increase of compaction to eliminate over compaction and bouncing - saves fuel, environment and money.

Improved engine, maximised performance
The Dynapac CA255 comes equipped with a powerful and fuel-efficient water-cooled KOEL engine, which ensures that this soil compactor gives non-stop performance and maximum reliability at the lowest operating costs.

Improved hydraulics, optimised results
The Dynapac CA255 features an advanced hydraulic system, which comes with a host of features that ensure high efficiency: Closed loop hydraulic circuit; Various hydraulic components from world leading brands; Low hydraulic tank volume: 52 litre; Hydraulic oil changing frequency: 2,000 hours

Improved service access & security
The CA255 comes with gas strut mounted, FRP hood which allows easy opening and lowering of hood and it gives complete service access to engine and hydraulics. The hood comes with a hood lock which means increased security and peace of mind.

Improved ergonomics - informative operator console
The Dynapac CA255 comes equipped with informative operator console, having vandalism protection cover as a standard fitment.

Heavy-duty steering hitch Best-in-class, heavy-duty, the steering hitch is as solid as possible, to avoid excess wear.

Improved convenience - extra storage space
The large inbuilt storage facility, under the seat, makes it possible for the operator to store personal belongings close at hand.

Unparalleled compaction performance
Static linear load
The more the better: CA 255 has the highest static linear load at 30.9 kg/cm

Amplitude

Higher the amplitude, greater the depth effect: Dynapac CA 255 offers two different amplitudes: High - 1.7 mm (thicker layers); Low - 0.8 mm (thinner layers)

Frequency
Optimised to match the amplitude

• Frequency of Dynapac CA 255: 33Hz
• Optimum frequency for best results
• CA 255 uses electronically operated vibration
• This reduces resonating frequencies that cause structural failure/driver discomfort

Intelligent compaction system
- CA 255 is equipped to have the compaction meter as an option
- Easy to read compaction meter with two scales available
- Gives the roller operator information on the increase in compaction for each pass:

• it shows variations in the rigidity of the underlying surface,
• it can localise weak areas, and
• it indicates when the material is fully compacted

- Avoids harmful bouncing, preventing structural damage
- Avoids extra passes, thus saving both time and money
Designed to improve productivity, these compactors have a canopy for improved weather protection to shield from sun and rain. With an easy and safe to open hood, it ensures improved ergonomics and the canopy mounted working lights ensure great visibility. Additional features such as engine hood locking facility, vibration dampener for operator comfort and extra storage space for ensuring convenience all work together to give the customer unparallelled compaction performance.
