Simple and efficient

LOOKING INSIDE THE

DYNAPAC CA35 SOIL ROLLER

DYNAPAC’S CA35 SOIL ROLLER COMBINES SIMPLICITY, AGILITY, ROBUSTNESS, AND COMFORT FOR OPERATORS, ALL WHILE NOT COMPROMISING PERFORMANCE, AS DYNAPAC PRODUCT MANAGER CHRIS PARKIN EXPLAINS.

Stripping back machinery to make them simpler to operate is unusual in the world of construction machinery, which is often dominated by intelligent and modern gadgets.

But as Dynapac Product Manager Chris Parkin tells Roads and Infrastructure, the decision to simplify controls within the Dynapac CA35 Soil Roller comes at no compromise to operators. In fact, it is intentional, he explains.

“Some machines within the industry are becoming quite complicated. That is why the CA35 was developed to be simple to operate,” he says.

This focus on ease of operation has resulted in a purpose-built machine for small and large project sites, where multiple operators may be using the machine.

Rather than a designated operator who may have more time to become familiar with a machine’s operating features, the CA35 Soil Roller has been designed so that operators can optimise the machine’s output quickly and effectively.

“The stripped back approach means you can have different operators using the machines and quickly adapting to its operation,” Parkin says. “All functions are easy to access, it’s all there and marked well.” LOWER FUEL BURN This is achieved by installing control components which are rationally distributed and easily readable. The machine has also been designed to reduce operating costs, utilising a Cummins QSF3.8 (IIIA) engine with a large fuel capacity of 280 litres.

“New technology used in the QSF3.8 engine means we can draw more power out of a smaller engine package, this leads to a lower fuel burn and emissions output. This is combined with the large fuel tank capacity allowing for the machine to be used for longer uninterrupted periods,” Parkin says.

The CA35 Soil Roller is agile, while still maintaining its 12-tonne weight class range.

“In addition, the service intervals remain longer than many competitor products within the roller category, reducing required maintenance costs over the life of the unit.”

The reduction in size also applies to the overall scale of the machine, which is 5600 millimetres long and 2890 millimetres wide, increasing the agility and speed of the machine during performance.

“The reduced length of the machine means it is more agile and easier to manoeuvre, which is ideal for operating within tight spaces, while not compromising the compaction you expect in this weight class,” Parkin says.

The size reduction, however, does not affect the machine’s output, maintaining its 12-tonne weight class and static linear load of 35 kilograms per centimetre.

MAINTAINING ROBUSTNESS The machine also does not compromise its robustness, with a fully welded chassis and frame. This includes the drum shell of the CA35 Soil Roller, which has a thickness of 30 millimetres and a diameter of 1510 millimetres.

“The drum shell is substantially thicker than competitors, which results in lower running cost and a longer wear life,” Parkin says.

Easily accessible greasing points also make maintenance easy for operators.

As Parkin adds, cab comfort is another aspect where Dynapac has not compromised. The CA35 Soil Roller also features a fully enclosed air-conditioned cabin.

“Both cabin and operators’ seat are vibration dampened and the seat has a rotation function which increases comfort and visibility for operators.”

Safety is guaranteed with an operator seat interlock sensor, hydrostatic brake, and failsafe emergency brake, allowing for the instantaneous shutdown of the machine in case of emergency.

While the CA35 does feature a stripped back design, premium features are available for operators. These include an optional GPS installation, which can show fleet owners the location of the machine or the installation of a Compaction Meter system to aid in ensuring the compaction process is being carried out completely and efficiently.

All components are supported by CEA, as Parkin explains.

“Our national network of CEA branches support customers throughout Australia. We have sites in every capital city except for Darwin. Combined with our regional service agents we are able to support customers for after sales support, repairs and warranty nationwide,” he says.

“Customers can expect quality, reliability and minimal servicing costs all while maintaining maximum compaction efficiency and output. These are staples of Dynapac products.”

The CA35 Soil Roller is fitted with a fully enclosed air-conditioned cabin.

Like other Dynapac products, the CA35 Soil Roller ensures that operators can operate with minimal maintenance.
