CAT Roller (Vibratory Soil Compactor) is Caterpillar's industry-leading single-drum compaction line, ranging from 7-ton compact to 20-ton heavy models — engineered for road construction, subgrade preparation, dam projects, quarries, and large earthworks. Renowned for CAT ACERT™ power, intelligent vibration, and optional integrated Grade Control — delivering higher density in fewer passes.

Powered by CAT C3.4B / C4.4 ACERT™ diesel engines — 55–117 kW (74–157 HP) — meeting Tier 4 Final / Stage V emissions. Hydrostatic all-wheel drive provides smooth stepless travel up to 11–12 km/h and 30–39° gradeability. Advanced vibration system: dual frequency & dual amplitude — High Amplitude for deep lift compaction; Low Amplitude for finishing — centrifugal force from 67 kN (CS34) up to 301 kN (CS19).

Drum width 1,270 mm (CS34) → 1,676 mm (CS44B) → 2,134 mm (CS10 GC / CS19). Smooth Drum for granular soils; Padfoot/Sheepfoot Drum (CP-series) for clay and cohesive soils. Optional CAT Compact GPS/GNSS Grade Control — real-time compaction monitoring, pass counting, and thickness mapping.

STIC™ single-lever steering & transmission control, spacious ROPS/FOPS cab with panoramic visibility, air-suspension seat, and intuitive LCD display. Extended 500-hour service intervals, ground-level service points, and permanently lubricated bearings — lowest operating cost in class. Available in Standard, GC (Economy), and Grade Control Ready configurations.
