Cat CS78B Soil Compactor Specifications
Compaction Specs
The Cat CS78B Soil Compactor is a heavy-duty vibratory soil compactor designed to deliver world-class productivity and exceptional compaction performance. Engineered specifically for large-scale civil construction, road building, and major earthmoving projects in the Australian market, this machine excels at compacting cohesive and semi-cohesive soils. Its robust design and high-amplitude vibratory system ensure deep compaction depth and fewer passes, making it a highly efficient choice for demanding worksites.
Equipped with a spacious, ergonomic cab and advanced compaction control technology, the CS78B maximises operator comfort and operational precision. The machine features a reliable Cat engine that meets stringent emissions standards while delivering high torque and fuel efficiency. Whether working on highways, runways, or industrial site preparation, the Cat CS78B provides the reliability and compaction density required to meet strict engineering specifications.

Additional Information
The Cat CS78B features an exclusive dual-pump propel system that provides separate, balanced hydraulic flow to both the rear wheel axle and the front drum drive. This unique engineering design delivers exceptional gradeability and tractive effort in loose materials or steep slopes. Additionally, the machine can be equipped with Cat Compaction Control, an optional technology that provides soil stiffness measurements to the operator in real-time, eliminating guesswork, preventing over-compaction, and ensuring uniform density across the entire work area.
