The Cat CW16 pneumatic (rubber-tire) roller is designed for use on granular materials and all types of asphalt-mix designs.

The CW16 is designed for work on highways, city streets, county roads, lane additions, industrial sites, overlays, or other mid-size jobs. It 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.

Depending on ballast used (including water, sand, steel, or combinations), operating weight of the CW16 varies from an 11,464-lb. base configuration to an approximate maximum weight of 33,000 lbs. for the nine-wheel configuration and 32,850 lbs. for the 11-wheel configuration. Operating weight can be adjusted to suit job requirements. Per-wheel weight can be varied from 1,280 lbs. to 3,680 lbs. for the nine-wheel model and from 1,060 lbs. to 2,975 lbs. 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. A tire overlap of 1.25 inches 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, and heat-retention aprons are available.

Two engines are available for the CW16 to meet regional emissions requirements. The Cat C3.4B ACERT engine meets U.S. EPA Tier 4 Final standards, and the Cat C4.4 meets the equivalent of U.S. EPA Tier 3 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 optimum mat quality. Both engines are rated at 101.9 hp.
