Soil rollers

The Dynapac CA30 Rhino soil roller is a heavy hitter and versatile workhorse for all conditions.

The Rhino series, CA30 is part of 84-inch drum width 12 ton static weight class that is available in both Smooth Drum (CA30D) and Pad Foot Drum (CA30PD) configurations.

Built for the rental market
There is a growing demand from rental companies for a soil roller that provides high-quality compaction results combined with better return on investment. Dynapac CA30 Rhino series offers the same by combining our core value of designed to perform and built to last along with offering right solutions for the right customer segment.

“The CA30 Rhino series is even more attractive with its simplified operation concept, which allows for entry-level to veteran operators to easily learn and control all functions to achieve high quality results while still including necessary features that are normally only found in much more complex machines,” says Vijay Palanisamy, vice president of product marketing and communications. “This makes it an ideal choice for rental companies and contractors to provide heavy-hitting compaction performance, high quality results and value for their money.”


Operator comfort first
The CA30 Rhino comes equipped with a spacious and vibration-damped open ROPS/FOPS or enclosed cab with AC and heat. The operator platform offers lasting comfort even during long shifts. The operator has excellent visibility from his or her seat to have a perfect view over the entire working area and their surroundings with no structures blocking any vital sight lines.

The seat can be rotated to enhance the operator’s visibility across the job site as well as increasing comfort when operating in reverse, reducing stress on the body. The CA30 has four LED working lights as standard to facilitate night work. The visibility can be further improved with the addition of an optional back-up camera to increase job site confidence by providing the operator with a constant view over their complete working area.

All operator controls are similar and easy to use, speeding the learning curve. All necessary functions are located on the dashboard, with easy-to-understand symbols and vibration activation is integrated into the forward and reverse lever. Each button has user-friendly selectable modes with pictorial language along with LED lights to show the activation.

The CA30 Rhino maintains a superior compaction output with an effective static linear load of 168 pounds per inch across the full 84-inch width of the drum. The standard setup consists of dual amplitudes alternating between 0.072 in at high amplitude and 0.035 in when set to low amplitude, both of which occur when operating at a frequency of 1980 vpm, generating up to 56,200 pounds of centrifugal force. The machine is equipped with Automatic Vibration Control (AVC), which when activated, causes vibration to not initiate until the forward and reverse lever leaves the neutral position, avoiding any inadvertent vibration while the machine is idling or loading on trucks to prevent damaging the compacted material as well as restricting any unnecessary wear and tear to the drum and the machine itself.

Another standard feature on the CA30 Rhino is the Dynapac patented Efficient Eccentrics System, reducing the power needed while starting the vibration up to 50 percent, thereby reducing the fuel consumption. This system also lowers the amount of oil needed within the drum cartridge. The system helps to maintain uncompromised superior compaction performance while lowering the operating cost for the contractors. This is done by reducing the energy required to initiate vibration at start-up by 50 percent, keeping the machine running longer and limiting wear and tear.

Compaction results can be confirmed with the optional Dynapac Compaction Meter (DCM). This smart compaction system is an accelerometer-based solution that can be either factory installed or added onto the machine after purchase with a field kit. The Dynapac Compaction Meter can be used to ensure that the compacted area is completely homogenous. It can be used to locate weak areas within the job site that need further compaction. The DCM will indicate when the material has reached the required compaction level, through Compaction Meter Value (CMV) analysis, to ensure a properly compacted job site and avoiding an unnecessary number of additional passes and saving fuel. Included with the DCM is the Dynapac Bouncing Indicator (DCI), which will alert the operator if the drum begins to bounce.

The CA30 has a four-speed manual transmission and a no-spin rear differential axle to provide the needed traction for any situation. It is controlled by an intuitive user interface integrated into the operation control panel to provide support for up to 43 percent gradeability in the smooth drum variant CA30D or up to 53 percent in the CA30PD, the padfoot model.

The CA30D can also be equipped with a two-piece bolt-on padfoot shell which can be utilized for compaction of cohesive and semi-cohesive soils. This increases the versatility of the machine for rental needs, ensuring the right machine for application is available and high-quality results are achieved on any type of material.

Lower emissions
The CA30 Rhino comes with the latest emission reduction technology that fulfills worldwide emission regulations while ensuring greater safety, comfort and the well-being of people and their surroundings. The CA30 Rhino comes with Dynapac's patented efficient eccentrics which provide optimal performance during the vibration start-up process. Its fuel-efficient Cummins diesel engine is especially efficient and offers maximum up-time. For North America, the machine is equipped with 134 horsepower Tier 4 final-compliant Cummins engine.

The CA30 Rhino offers excellent serviceability with easily accessible daily service and maintenance points from ground level. The hydraulic pumps are in line with the engine, so that all can be accessed and serviced from the ground. The same holds true for all filters and fluid access points, avoiding any need for additional tools or assistance.
