Case Construction Equipment’s new PT240D pneumatic tire roller is designed to require fewer passes and improve penetration and compaction density.
It is built for sub-base and asphalt compaction on large road and highway projects, airport runways and commercial development. The compactor runs on a 100-horsepower, turbocharged, Tier 4 Final Deutz engine. The engine requires no diesel particulate filter, instead using a diesel oxidation catalyst and selective catalytic reduction to meet federal emissions requirements.
The roller delivers a compaction width of 78.2 inches. Its operating weight is 21,380 pounds and 52,910 pounds at full ballast, which can be sand, steel or water. The roller has four tires in front and four in the back with 2-inch tire overlap that gently kneads hot-mix asphalt as it rolls across it. The company says that leads to greater asphalt density and reduces the chance for voids.
A 103-gallon polyethylene water tank delivers pressurized water to prevent asphalt from sticking to the tires. Each of the front tires oscillate, which the company says minimizes bridging and maximizes compaction.
An automatic central tire-inflation system keeps consistent pressure to all of the tires, and the pressure can be adjusted to ground conditions and compaction needs, the company says. The dual operator stations offer visibility down with side of the roller. They are equipped with suspension seats and ergonomic controls.
Standard features include a fixed ROPS open platform with anti-vandalism cover, halogen work lights and a tilt-open hood. Options include a sealed, heated cab with HVAC and radio, thermal aprons for keeping the tires warm in cooler weather, tiltable scrapers and locking rear differential. The PT240D is also available with Case’s SiteWatch Telematics, including hardware and three-year Advanced data subscription.
