Equipment Overview
The CAT CP56B is a padfoot drum vibratory soil compactor built for cohesive and semi-cohesive soil applications, with a 2,134 mm drum width fitted with 140 oval pads. It has an operating weight of 11,400 kg (with ROPS/FOPS canopy), suited to road construction, aggregate bases and larger earth fills in the 10–12 tonne weight class.
Power comes from a Cat C7.1 engine producing 116.5 kW (156 hp), driving a dual pump propel system with separate flow to the drum drive and rear axle for strong gradeability and traction. The vibratory system runs at 30.5 Hz with up to 301 kN of centrifugal force, and Cat Compaction Control (Machine Drive Power) helps the operator confirm when specified density has been reached.
