Atlas Copco’s CA1300 single-drum soil roller supplies high maneuverability and visibility on parking lot, road, utility pipe and street projects.
The engine on the CA1300 is cross-mounted, or placed perpendicular to the frames, which is an industry first. The roller’s 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 engine is cross-mounted rather than parallel to the frame, the roller provides optimal weight distribution and contributes to the units’ minimal footprint.
The CA1300 features a Tier 4 Final, 75-horsepower Kubota diesel engine. It has 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 roller’s 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). The compaction power is transferred through the roller’s drum to efficiently compact soil with minimal passes.
The CA1300’s 54-inch drum gives operators optimal visibility and allows them to maneuver into tight workspaces, such as pipe trenches or road shoulders. “With high visibility, operators can monitor the drum and keep an eye out for nearby workers,” said Tim Hoffman, Atlas Copco Dynapac product manager. “This means operators don’t need to sacrifice productivity or safety when working on cramped worksites.”
The service alerts systems and easy-access engine allows contractors to service and maintain the roller on the worksite without taking them to a service station. The service interval alert in the instrumentation display indicates when and what type of maintenance is required.
Optional strike-off blades help the roller’s consistency by removing oversized rocks and obstacles in front of the thick drum shells. The blades have an innovative, divided profile that efficiently pushes out rocks, which can break up compacted soils. All Atlas Copco pad foot rollers are fitted with heavy-duty drum scrapers to keep the drums clear of clay and mud, which ensures consistent compaction.
For environmentally sensitive worksites, the CA1300 features Atlas Copco’s ECO Mode, an rpm-management system. The system reduces fuel consumption as much as 20 percent by delivering to the roller only the amount of power that is necessary to operate at any given time.
