New Compact, Versatile Dynapac Roller
Atlas Copco’s new Tier 4 Final compact CA1400 soil roller offers two speeds and amplitudes for added versatility on a variety of applications. The roller’s cross-mounted engine allows technicians to easily access all necessary components, minimizing downtime. The company will feature the new soil roller at booth 4047 during The Rental Show in Atlanta, Feb. 21 - 24.
“Rental centers look for equipment that is versatile and easy to maintain, and contractors want productivity. We designed the CA1400 with those features in mind,” said Tim Hoffman, Atlas Copco rollers product manager. “Like all of our road construction equipment, the CA1400 has an ergonomic operators’ station to maximize comfort, which contributes to overall productivity. And its tested and proven gradeability, along with dual amplitude and speed, provide versatility for many compaction projects.”
The CA1400’s 66-inch-wide drum and two amplitudes — .032 inches and .067 inches — allow rental centers to offer contractors one unit for compacting a wide range of materials. Using the adjustable settings, operators can change the amplitude to suit different lift thicknesses.
Operators can set the speed on the CA1400 to high or low to achieve different compaction results on a variety of applications and materials. Due to the compact size, the CA1400 works well for compacting materials on large building foundations and industrial construction sites. The CA1400 offers operators optimum gradeability to easily maneuver up and down steep slopes.
The roller is offered with a smooth-drum or pad-drum. The roller’s high, static linear load of 112 pounds per linear inch make it ideal for compacting thin layers of materials, such as silt, clay and gravel. Compaction power from its eccentric weights transfers through the roller’s drum to efficiently compact sand and gravel as deep as 20 inches with minimal passes. The PD version will compact silt and clay at a depth of 18 inches.
A cross-mounted 75-horsepower Kubota diesel engine sits perpendicular to the CA1400’s frame. This allows technicians to reach all necessary engine components and hydraulic systems for easy servicing. A 12-volt outlet within the engine compartment can power lights allowing operators a clear view of the engine at night or during low-light conditions.
With Atlas Copco’s ECO Mode rpm-management system, the engine generates only the amount of power needed to operate at any given time, which reduces fuel consumption as much as 15 percent.
An operator station gives workers a clear view of the drum’s edge and surroundings and helps eliminate the need for operators to twist and lean to see the work area. The station is insulated to minimize harsh body and hand/arm vibrations.
The roller includes safety features such as a back-up alarm and battery disconnect switch on the operators platform. As with all Dynapac machines, the parking brake is separated from the forward and reverse lever to minimize the risk of unintentionally releasing the brake.
