Case announces PT240D pneumatic tire roller for asphalt paving
February 12, 2020 by Megan Hoegler
Case Construction Equipment has announced the Tier 4 Final PT240D pneumatic tire roller.
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 and other large commercial developments.
This pneumatic tire roller 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.
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.
Other features include an iso-static front axle that allows each of the front tires to oscillate — helping to maintain contact with the ground at all times to minimize bridging and maximize compaction. A standard automatic central tire inflation system ensures consistent pressure to all eight tires and allows for easy adjustment of tire pressure to meet ground conditions and compaction needs. The machine’s specially designed tire configuration and long wheelbase provide reliable, uniform material compaction.
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.
