Cat CP74B Padfoot Compactor Specifications
Compaction Specs
The Cat CP74B Padfoot Compactor is a high-performance soil compactor engineered to deliver exceptional compaction depth, productivity, and gradeability on challenging Australian jobsites. Featuring an advanced vibratory system and a heavy-duty padfoot drum design, this machine is purpose-built for cohesive and semi-cohesive soils, making it a staple in major civil infrastructure, road construction, and large-scale earthmoving projects.
Equipped with an efficient Cat C4.4 engine and an exclusive dual-pump propel system, the CP74B provides outstanding traction and climbing capability on steep slopes. Operators benefit from an ergonomic, high-visibility cab designed to reduce fatigue and maximise on-site safety, ensuring consistent, high-density compaction results across demanding Australian conditions.

Additional Information
The Cat CP74B features Caterpillar’s proprietary pod-style vibratory system, which is virtually maintenance-free with a 3-year or 3,000-hour service interval. The machine’s dual-pump propel system provides separate, dedicated hydraulic flow to both the rear wheels and the drum, delivering unmatched gradeability and tractive effort in deep lifts or soft underfoot conditions. Additionally, optional Cat Compaction Control technology provides real-time compaction measurements to the operator, significantly improving efficiency by reducing the number of passes required to achieve target density.
