Get it dense and keep it smooth. Cat Tandem Vibratory Rollers do that and more. Caterpillar offers a vibratory system for every application. Most models have high frequency combined with low amplitude that match high paving speed on thin lifts as well as low frequency with high amplitude that match low paving speed on thick lifts of stiff material. As stand-alone units or as complements to high production tandem rollers, Cat Utility Rollers set the standards for versatility and reliability. A wide range of drum widths lets you precisely match the machine to the job requirements—whether it's a narrow shoulder, a patching project, a parking lot or a bicycle path. Vibratory systems are characterized by high frequency for fast working speed and high compaction energy for getting density in the fewest passes.

Benefits
Simple to Operate, Easy to Learn
- Large, full-color displays keep the operator informed of machine functions including water and fuel levels, impact spacing, and mat temperature.
- Innovative hand-wheel steering technology delivers precise control and good forward visibility.
- Easily activate the vibratory system, water spray system and drum offset with the multi-function propel handle.
- Machine functions with LED indicators have been independently grouped for simplified control and quick activation.
- Rotary dials with green light indicators provide a quick visual reference and fingertip feel for quick adjustment to speed control and water spray timers.
Better Fuel Economy
- Get up to 10% better fuel economy with the Cat C3.6 engine and standard Eco-mode.
- The C3.6 engine provides 74.4 kW (100 hp) of power and meets U.S. EPA Tier 4 Final emissions.
- Unique Eco-mode design modifies engine speed based on load requirements; high amplitude vibration utilizes higher engine speeds, while static rolling conserves fuel and operates at low engine speed with even lower sound levels.
Work Safer with Enhanced Visibility
- Optional top down, 360 viewing utilizes cameras mounted in each corner of the ROPS for excellent work-zone visibility. This option utilizes a high-definition display mounted to a swivel on the upper left side of the ROPS.
- Optional fore and aft cameras mounted in the front and rear bumpers provide outstanding visibility when approaching obstacles. The camera view is integrated into the main operating display.
- Optimize sight lines with 360 seating option; always face the direction of travel.
- LED Lighting delivers excellent job site illumination while conserving energy.
- Night-lighting option provides additional illumination to the ROPS, drum edges, and drum surfaces.
Easy Vibratory System Set-up
- Two-amplitude/two-frequency vibratory system automatically optimizes amplitude and frequency with a single switch for simple thin/thick lift operation.
- Reach compaction goals with automatic speed control; green indicators help ensure travel speed matches correct impact spacing.
- Built-in application profiles for thin lift or thick lift applications can be quickly activated through the operating display.
- Single touch vibratory system profiles for frequency and speed help ensure optimal impact spacing.
Ensure Mat Coverage with Compaction Control
- Pass-count and Temperature Mapping combines infrared temperature sensors with GPS mapping to keep the operator informed of current asphalt temperatures, machine position, pass-count, and layer coverage.
- Compaction Meter Value (CMV) utilizes a drum-mounted accelerometer to measure the combined stiffness of the asphalt layer, base layer, and sub-base layer to indicate road structure quality beneath the surface.
Prevent Build-Up, Keep the Drum Surfaces Wet
- High capacity water tank provides long duration between fills
- Dual water pumps provide back-up capability and alternate with direction of travel to maximize service life.
- Triple filtration prevents clogs with filters located at the fill point, water pumps, and spray nozzles.
- Simple rotary dial provides adjustable spray settings and intermittent modes that help conserve water.
- Integrated freeze protection kit (optional) provides protection in cold temperatures when machine is not in use.
