Atlas Copco has now completed its Dynapac range of single drum soil rollers with the introduction of its CA1300 and CA1500 models. With the same features as the larger models in the CA soil roller range, the CA1300 and CA1500 feature fuel-efficient interim Tier IV/Tier IV Final engines, improved serviceability, built-in safety functions and increased operator comfort. Time- and money-saving features include optimized amplitude for superior compaction performance and active bouncing control (ABC) that prevents damage to the machine and over-compaction, according to the manufacturer.

Lower Cost Per Compacted Cubic Yard

With static linear loads ranging from 70 to 365 lbs. per in., the CA rollers are ideal for compacting a range of materials, from sand and gravel to rock fill plus silt and clay. Amplitude of 0.071 to 0.079 in. (.18 to .2 cm) for the Dynapac CA3500 and CA4000 models allows rock fill to be compacted in 4 to 5-ft. (1.2 to 1.5 m) deep layers. The better depth effect results in higher volume capacity and fewer passes to reach compaction specifications, saving fuel and time and reducing cost per compacted cu. yd.

Environmental impact also is lower. The “silent weights” eccentric feature enhances compaction performance even further and is standard on Dynapac CA4000 through CA6500 models.

Lower Fuel Consumption and Life-Cycle Costs

The new CA rollers are available with fuel-efficient interim Tier IV engines. (The CA1300 is offered with a 75 hp Tier IV Final engine.) The ECO fuel-saving system minimizes fuel consumption and CO2 emissions by giving the roller only the amount of power that is necessary to operate at any given time. This, together with higher compaction parameters and other improvements, has resulted in a drastic reduction in fuel consumption compared to the previous generation, according to the manufacturer.

Rollers in the CA range can be equipped with a sustainability package featuring the ECO rpm management system, biodegradable fill-for-life hydraulic fluid, a 50-hour service kit, electrical engine block heater and working lights with LED lamps.

The thick drum shell on Dynapac CA rollers extends running time before a drum change is required. A scraper blade with a divided design keeps the drum free of material during operation and can be replaced quickly and at low cost should it become necessary. For PD applications a heavy duty scraper is available as an option.

Bouncing Guard Prevents Component Damage

Active bouncing control (ABC), a feature unique to Dynapac CA rollers, prevents damage and prolongs roller life by eliminating drum double jump, or over-compacting — an action that can destroy components in the machine. An optional speed limiter is available that prevents compacting at too high a speed, saving money in the long term. The speedometer is always standard to ensure the right compaction speed. Electronic drive control together with automatic vibration control gives the operator full control.

A New Level of Serviceability

A service interval alert in the instrumentation display indicates when service is required and what action to take. With the world’s first cross-mounted engine, the CA soil rollers offer excellent access for all service and maintenance needs. The engine hood is easy to open for quick maintenance, and the hydraulic pumps are in line with the engine and fully accessible for service.

The cross-mounted engine is easily accessible and gives both optimal weight distribution and ease of transportation as it keeps down machine length. The noise level is very low because the cooling air intake is placed at the top of the hood with the outlet down the sides, combined with the ejector exhaust outlet. This has the advantage of keeping the inlet air as clean as possible, an important factor in the dusty environments in which these rollers operate.

Productive Compaction Operations

The advanced control systems on the CA rollers increase productivity by enabling the user to control the entire rolling process in three clear steps. Preparation — planning the task with the Dynapac CompBase software; performance — performing the work using the compaction meter and analyzer on the roller; and protocol — analyzing the results using the Dynapac compaction analyzer (DCA).

Dynapac’s CostCtrl software on the Web and an extended warranty for CA rollers enable customers to gain full control over life-cycle costs and maximize machine availability. The company’s international service network offers full support and assistance with all parts and service needs.

Comfortable and Safe, With Low Noise and Good Visibility

The ergonomically designed, air conditioned cabs on the new generation offer a high level of operator comfort and good visibility over the work area and surroundings. A feature unique to Dynapac CA rollers equipped with CAB is a spin-around seat, steering module and display cluster, which allow movement of up to 180 degrees without stress to the neck or body and excellent all-round visibility. The view over the working area is always free of interference, wherever the operator is positioned. Noise levels in the new cabs are reduced to a level that allows the operator to remain alert even for long working periods, according to the manufacturer.

Safety functions include electronic drive control with a “quick brake” function, which shortens braking distances if the lever is moved very fast, and a tilt indicator. Loss of traction, even in the toughest conditions, is swiftly counteracted by an easy-to-use toggling gear shifting system or with an optional anti-spin system.

A Wide Range of Models and Options

The new CA rollers are available in standard models designed for an owner’s specifications and have an extensive choice of optional extras, such as a bolt-on pad shell for PD applications, a variety of scrapers, lights for night work and more.
