At this year’s World of Asphalt in St. Louis, Dynapac unveiled its new CP28, which it calls "the heaviest ballastable pneumatic tire roller on the market."
Eric Booth, compaction product manager at Dynapac North America, gave us a walk-around tour of the new compactor in the video above.
Booth says the CP28 is a staggered roller with four wheels in front and back, and it can be ballasted from 21,000 to 68,000 pounds. Ballasting the CP28 can be done by either adding steel plates to the front or rear compartments or using materials like wet sand, water, steel shot and scrap metal.
The roller is designed for asphalt and soil compaction and can reach speeds up to 12 mph.
The CP28 comes with EcoMode and EcoSave tech to save fuel by running on low engine rpm and automatically turning off the engine if idling too long.
Each tire has its own sprinkler system, scraper bar and cocoa mat to avoid picking up asphalt.
Powered by a 134-horsepower Cummins engine, the CP28 is 17 feet long, 6.8 feet wide and 9.8 feet tall.
One of the big upgrades on the new CP28 is a new operator station. The roller can be fitted with either a symmetrical or asymmetrical cab, and Booth emphasizes the clear operator visibility.
“We've got a new operator station for this generation of the roller, so it's like our heavy tandem rollers,” Booth says. “It's got a 7-inch touchscreen, and all the activities that you need daily are on a keypad on the righthand side ... that swivels and slides with the operator.”
Another key feature is the “Air on the Run” system. When activated from the operator station, it can bring all the tires from 0 psi to 12 psi in around 12 minutes.
A new suspension on the front is designed to tilt and oscillate during proof rolling or dirt passes, maintaining tire contact at all times. In the front, there is 4.5-degree lateral oscillation and a 1.5-degree tire tilt to the right and left, and the rear suspension offers 2 degrees of tire tilt.
