Caterpillar PS-360B

The Caterpillar PS-360B is a self-propelled, pneumatic (rubber-tired) compactor built for finish rolling on asphalt, soil, and reclamation work, and it sits at the top of Cat's B-series pneumatic compactor line above the PS-150B, PS-200B, and PS-300B. It runs a Cat 3054T turbocharged diesel rated at about 78 kW (105 hp) gross, driving the machine through a hydrostatic propel system. Operating weight runs from roughly 8,500 kg (18,740 lb) unballasted up to about 25,000 kg (55,115 lb) with the ballast tank filled with water, sand, or steel shot, giving a compaction width near 2275 mm (7' 6") across seven overlapping, oscillating tires (three front, four rear). Cat sold the PS-360B mainly through the 1990s and into the 2000s; exact production start/end dates are not consistently documented. It followed an earlier PS-360 pneumatic roller and was later replaced by the PS360C, with pneumatic-tire compaction eventually carried forward under Cat's modern CW-series rollers.

Across the B-series, Cat standardized the 3054 diesel family and hydrostatic drive on these pneumatic compactors, though displacement and aspiration varied by model (naturally aspirated on the smaller PS-150B, turbocharged on the PS-200B, PS-300B, and PS-360B), so power and tire counts are not interchangeable between siblings. The follow-on PS360C moved to a C-suffix engine update, and later Cat pneumatic rollers adopted modular, quick-change ballast systems and single-point tire inflation not offered on the B-series. Because PS-360B production ended years ago, most units in the field today are secondhand and worked hard on paving and landfill jobs, so the used market leans on remanufactured hydrostatic pumps and motors, oscillating axle components, and tire/rim assemblies rather than new-old-stock parts. Buyers still value the model for its simple, mechanically-injected engine and rugged axle design, which keep it serviceable well past the point where more electronically-controlled compactors become parts-constrained.
