Benefits and Features

Comfortable Operating Station

The machine controls and LCD display are integrated with the pivoting adjustable seat, and move with the operator. Seating options include vinyl for open-platform configurations and cloth for cab, both can be equipped with a heated option. An optional deluxe highback air-ride seat is also available. Other comfort features include a vibration-absorbing floor mat, 12-volt power receptacle that supports communication devices, wide-width seat belt, cup holders and a lockable storage compartment.

Fingertip Control

The multi-function propel lever with integrated controls for water spray on/off, drum offset, vibratory control, and optional edge cutter height adjustment enables the operator to work with confidence.

LCD Display

The back-lit LCD display includes machine data and diagnostics. It is integrated with the seat, so it remains in the same position even as the seat pivots. A built-in lockable anti-vandalism cover offers protection. The display provides multiple language options, split-screen capability, and indicators for ground speed, vibrations per minute, and fuel level.

Convenient Console

The console is integrated with the seat, providing fingertip access. Soft keys with tactile feel provide instant feedback to the operator for intuitive operation. The armrests are adjustable and can be tailored to the operator for additional comfort.

2-Amplitude, 2-Frequency Vibratory System

The 2-amplitude, 2-frequency vibratory system can be tailored to match thin and thick lifts with the flip of a switch for excellent versatility.

Performance Features

The vibratory systems offer multiple options that help fine-tune performance on thick challenging lifts. The automatic speed control feature makes it easier to maintain consistency and impact spacing requirements. Also, an auto vibe function helps prevent over-compaction and contributes to uniformity.

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.

Compaction Meter Value

Compaction Meter Value (CMV) technology utilizes a drum mounted accelerometer to measure and record forces of the vibrating drum.

Machine to Machine Communication

Machine to Machine communication helps improve job site efficiency by enabling operators to view rolling patterns of other machines on the job site. It helps operators pickup where other compactors left off in their rolling pattern. The system is also a difference maker in nighttime operation due to the difficulties associated with low light conditions.

Cat C3.4B Engine

The C3.4B engine provides 75 kW (100 hp) of power and meets U.S. EPA Tier4 Interim and EU Stage IIIB emissions. It features an electronic control module (ECM), providing optimal performance through precisely synchronized timing and fuel delivery. The ECM enables advanced troubleshooting and diagnostic capabilities using Electronic Technician (Cat ET). Cat dealers are the single-source providers of all machine and engine warranty service (a Cat exclusive).

High Capacity Cooling System

The large capacity cooling system keeps the operating temperatures low, even in extreme conditions. The high capacity fan directs warm air away from the operator for a more comfortable operating environment.
