Case unveils new tyre roller for asphalt paving

0

Case Construction Equipment has unveiled its all-new Tier 4 Final PT240D pneumatic tire roller for the first time at Nashville’s Pavement Expo. The machine is designed to achieve compaction in fewer passes and provide improved penetration and compaction density ideal for today’s asphalt paving applications requiring tight density tolerances.

With an operating weight of 21,380 pounds (52,910 pounds at full ballast), a turbocharged 100-horsepower Deutz engine and a compaction width of 78.2 inches, the PT240D is built for sub-base and asphalt compaction on large-scale road and highway projects, airport runways and other large commercial developments.

The tire configuration (four in front, four in back) with two-inch tire overlap ‘kneads’ hot mix asphalt gently at the surface as it rolls across it. The result is greater asphalt density and fewer possibilities for voids that can lead to flaws/deterioration. The PT240D is designed to handle up to 31,530 pounds of ballast — including steel, sand and water — to meet the compaction requirements of any job. A large polyethylene water tank supplies a pressurized water feed system to prevent asphalt from sticking to the tires — and, at 103 gallons, allows operators to run for longer periods of time without refilling.

Dual operator stations provide maximum visibility to either side of the machine, and feature comfortable suspension seats and advanced ergonomic controls designed for operators of all experience levels. Like all Case machines, the PT240D pneumatic tire roller is designed for easy serviceability.

The PT240D achieves Tier 4 Final compliance with a fuel-efficient and maintenance-free combination DOC (Diesel Oxidation Catalyst) and SCR (Selective Catalytic Reduction) aftertreatment system. There is no diesel particulate filter (DPF) or associated lifetime service costs—maximizing uptime and performance. All fluid ports, drains and service checkpoints are grouped for simplified maintenance procedures.

Standard features include a fixed ROPS open platform with anti-vandalism cover, an array of halogen work lights for improved jobsite safety and visibility, and an easy-to-use tilt-open hood, and spin-on fuel, engine oil and hydraulic filters for streamlined maintenance. An upgraded frame design with improved tie-downs simplifies transportation.

Optional equipment includes a sealed, heated cab with HVAC and radio, thermal aprons for keeping the tires warm in cooler weather, tiltable scrapers, locking rear differential and more. The PT240D is also available with Case SiteWatch Telematics—including hardware and 3-year Advanced data subscription.
