Versatile Compaction Performance
- Compaction Width
Eight 13/80 R20 rubber tires provide overall compaction width of 2090 mm (82") with 25 mm (1") overlap.
- Flexible Ballast
Ballast options include modular and non-modular steel, sand, and water. The 6.5 metric ton (7.1 U.S. ton) modular steel can be easily added or removed through bolt-on side panels. The internal, non-modular steel consists of 6.1 metric tons (6.7 U.S. ton). Also, a 3 cubic meter (793 gal) water-tight chamber with baffled compartments prevent surge, and balance weight.
- Oscillating Tires
Oscillating front and rear tires deliver vertical and horizontal forces that reduce air voids, providing surface uniformity. Heat retention covers trap heat to keep the tires warm and prevent pick-up. They can be easily stored when not in use.
- Air-on-the-Run
The 13/80 R20 rubber tires can be equipped with the optional air-on-the-run system that enables the operator to quickly adjust tire pressures to increase or decrease static loads for optimal surface quality.
Exceptional Visibility and Control
- Operating Environment
The sliding and pivoting operator station rotates 90° to either side for ultimate comfort and control. The new console design includes an LCD display and push button machine controls that simplify operation for an all-around comfortable operating environment.
Cat® Compaction Control
- Dual Infrared Temperature Sensors
Dual infra-red sensors mounted on the front and rear of the machine deliver real-time readings that keep the operator informed of when to begin rolling and when to stop. This system helps operators avoid tender-zones that often occur in the 104º-110º C (219º-230º F) temperature range.
- Pass-Count Mapping
Pass-count mapping helps operators achieve target density and increase roller efficiency. The system records and monitors pass patterns in order to display coverage. The system also helps operators optimize drum overlap, simplify nighttime operation, eliminate second guessing and prevent incomplete passes such as stopping short.
- Temperature Mapping
Temperature mapping provides a visual readout of mat temperature in order to keep the machine in the proper temperature range. The system records and monitors temperature for future analysis of the proper temperature range.
Smooth Operating Powertrain
- C4.4 Engine
The C4.4 engine meets U.S. EPA Tier 4 Interim and EU Stage IIIB emission standards and provides 98 kW (133.2 metric hp).
- ECO-mode
Standard ECO-mode provides fuel efficiency and reduces sound levels.
