Atlas Copco's New Single-Drum Rollers

Atlas Copco has introduced its CA1300 and CA1500 single-drum soil rollers for maneuverability and visibility on parking lot, road, utility pipe and street projects. The new CA1500 roller features Atlas Copco’s exclusive Active Bouncing Control (ABC), a cross-mounted Tier 4 Interim or Tier 4 Final engine and steel blades that improve compaction, safety and visibility.

Atlas Copco RollerThe engines on the CA1300 and CA1500 are cross-mounted, or placed perpendicular to the frames, which is an industry first. The rollers’ hydraulic pumps are also in line with the engine. This allows users to reach all the necessary components on the engines and hydraulic pumps for fast and easy service and maintenance. And because the engines are cross-mounted rather than parallel to the frame, they provide optimal weight distribution and contribute to the units’ minimal footprint.

The CA1300 features a Tier 4 Final, 75-horsepower Kubota diesel engine, and the CA1500 uses a Tier IV Interim, 100-horsepower Cummins diesel engine. Both have top-mounted, cool air intakes with side vents that combine with the ejector exhaust outlet to minimize engine noise and prevent dust from being sucked into the engine compartment, which is a common occurrence on soil compaction sites.

The rollers’ high static linear loads make them ideal for compacting a range of materials, from clay to rock fill. The CA1300 features a static linear load of 73 pounds per linear inch (PLI), and the CA1500 has 112 PLI. The compaction power is transferred through the rollers’ drums to efficiently compact soil with minimal passes.

The CA1300’s 54-inch drum and the CA1500’s 66-inch drum give operators optimal visibility and allow them to maneuver into tight workspaces, such as pipe trenches or road shoulders. “With high visibility, operators can monitor the drums and keep an eye out for nearby workers,” said Vijayakumar Palanisamy, Atlas Copco Dynapac product marketing manager. “This means operators don’t need to sacrifice productivity or safety when working on cramped worksites.”

Atlas Copco’s ABC system, an optional feature for the CA1500 through CA6500 models, prevents operators from over-compacting the soil, which can damage the rollers. “We created our exclusive ABC system specifically to help contractors get the most life from their compactors by minimizing a main cause for roller repairs,” Palanisamy said. “Without double jumping, the equipment stays in the field longer; compaction is more efficient; and the ROIs are greater.”
