Cat launches new pneumatic roller

Caterpillar has launched a new rubber-tired roller designed for use on granular materials and all types of asphalt mixes.

The new Cat CW16 pneumatic roller is available as a standard nine-wheel model with a 69-inch compaction width or as an optional 11-wheel model with an 84-inch compaction width.

The operating weight varies from an 11,464-pound base configuration to an approximate maximum of 33,000 pounds for the nine-wheel configuration and 32,850 pounds for the 11-wheeler, depending on ballast used. Water, sand, steel or a combination can be used to adjust the operating weight to suit job requirements.

Oscillating front wheels assist in compacting soft voids across the entire machine width. The tire overlap of 1.25 inches has been designed to provide 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, and heat-retention aprons are available.

The CW16's pressurized water-spray system is designed with dedicated spray nozzles for each wheel. Triple filtration (with filters at the fill point), in conjunction with the design of the water pump and spray nozzles, provides protection against clogs. An adjustable intermittent-spray mode conserves water and reduces the number of refills required.

The Cat C3.4B Acert engine meets US EPA Tier 4 Final/EU Stage IV standards. The engine is rated at 101.9 horsepower.

The CW16's two-speed hydrostatic propel system is electronically controlled and designed to provide both site maneuverability and speeds up to 12 mph (19 km/hr). The propel system automatically shifts between speed ranges and has a coast feature that conserves fuel.
