Atlas Copco’s sophisticated new soil compactor

161 Atlas Copco is now offering its new compact CA1400 soil compactor, which is aimed at the rental market in particular. This machine is Tier 4 Final compliant and features two vibration speeds and amplitudes for added versatility on a variety of applications, such as compacting areas where utility works have been carried out, or road base and parking lot construction.

The machine has a transverse-mounted 1265 Kubota diesel delivering 56kW. This layout is said to be easier to access for maintenance, as well as ensuring that the rear end design is compact and offers optimum weight distribution. The firm claims that the CA1400 offers ease of service, high versatility, and optimal gradeability, suiting customers in the rental sector.

The CA1400 has a1.68m wide drum and two amplitudes of 0.08mm and 0.17mm and using the adjustable settings, operators can change the amplitude to suit different lift thicknesses. In addition to two amplitudes, operators can set the speed on the CA1400 to high or low to achieve different compaction results on a variety of applications and materials.

The machine’s compact size allows it to operate in restricted space areas, such as alongside highway barriers while its good gradeability and low centre of gravity means it can operate on steep slopes. To ensure consistent speed and precise operation, the CA1400 features high flotation tyres and a differential lock, as well as a drum drive system delivering high traction in forward or reverse. This design is also said to allow for ease of operation on the jobsite and can help boost productivity.

The firm offers the CA1400 with either smooth or padfoot drums, while the high, static linear load is said to suit it to compacting thin layers of materials such as silt, clay and gravel. Compaction power from its eccentric weights transfers through the roller’s drum to compact sand and gravel as deep as 510mm with minimal passes. The PD version will compact silt and clay at a depth of 457mm.

A novel feature is its 12V outlet within the engine compartment that can be used to power lighting and a clear view of the engine at night or during low-light conditions. The CA1400 has top-mounted, cool-air intakes with side vents that combine with the ejector exhaust outlet to minimise engine noise. This also prevents dust from entering the engine compartment, which can occur when compacting dry loose soil.

The firm’s ECO Mode rpm-management system helps lower fuel consumption and CO2 emissions, resulting in a fuel saving of up to 15%. Operators also can switch the engine to run at high rpm for heavy climbing or starting the vibratory function of the roller.

Other benefits of the model include efficient ergonomics, low vibration in use and good all round visibility, with the operator having a clear view of the drums edge.
