Caterpillar creates new rubber tire roller

Caterpillar’s new CW16 pneumatic rubber-tire roller is designed for use on granular materials and all types of asphalt-mix designs.

The machine is available as a standard nine-wheel model with a 175-cm compaction width or as an optional 11-wheel model with a 213-cm compaction width.

The CW16 was created for use on highways, city streets, county roads, lane additions, industrial sites, overlays or other mid-size jobs.

Depending on ballast used — including water, sand, steel or combinations — the operating weight of the CW16 varies from a 5,200-kg base configuration to a maximum weight of about 15,000 kg for the nine-wheel configuration and 14,900 kg for the 11-wheel configuration. As well, the operating weight may be adjusted to suit job requirements. Per-wheel weight can be varied from 580 kg to 1,670 kg for the nine-wheel model and from 480 kg to 1,350 kg for the 11-wheel model.

Oscillating front wheels assist in compacting soft voids across the entire machine width, and the 11-wheel configuration increases efficiency in chip-and-seal applications.

As well, a tire overlap of 32 mm ensures even compaction across the surface. Each wheel is equipped with self-adjusting scrapers, and a water-spray system deters material from adhering to the wheel surface. Standard cocoa mats help retain water to keep wheels wet. Heat-retention aprons are available.

The CW16’s pressurized water-spray system is designed with dedicated spray nozzles for each wheel. The system includes a single water pump, triple filtration and adjustable intermittent operation. Triple filtration with filters at the fill point — in conjunction with the design of the water pump and spray nozzles — provides protection against clogs. The adjustable intermittent-spray mode conserves water and reduce the number of refills required.

The roller is equipped with a102 hp Cat C3.4B ACERT engine that meets Tier 4 Final/EU Stage IV standards. An Eco-mode, in combination with an exclusive automatic speed-control system, is designed to save fuel, lower sound levels and deliver smooth transitions for mat quality.

The CW16’s two-speed hydrostatic propel system is electronically controlled and designed to provide both jobsite manoeuvrability and speeds up to 19 km/h. The propel system automatically shifts between speed ranges and has a coast feature that conserves fuel. Tire choices include a 12-ply 7.5 x 15 radial or a 14-ply 7.5 x 15 bias-ply.

The roller is designed to provide more visibility for the operator, the result of a newly designed console and the machine’s standard, rotating operator’s station. An LCD display and push-button controls simplify operation for a comfortable operating environment. A ROPS canopy or sun canopy are available.

The standard, 500-hour, engine-oil-service interval reduces both routine-maintenance time and overall operating costs.

The CW16’s large-capacity hydraulic and engine cooling systems keep components at optimum temperatures, even in high ambient temperatures, extending service life for such critical components as hydraulic pumps and motors, according to Caterpillar.
