Equipment Overview
The CAT CB44B is a tandem double drum roller built for asphalt compaction, with 1,500 mm drums on both ends of the machine. It has an operating weight of 7,990 kg, suited to a variety of asphalt mix designs and other granular materials on medium-to-large paving jobs.
Power comes from a Cat C3.4B engine with ACERT technology producing 102 hp (75 kW), meeting US EPA Tier 4 Interim and EU Stage IIIB emissions. The drums vibrate at up to 0.64 mm amplitude with a centrifugal force of up to 77 kN per drum, and the machine has an inside turning radius of 4,478 mm. A 742-litre water tank keeps the spray system running for extended periods between refills.
