Benefits & 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 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.
Exceptional Visibility and Control
The B-Series Tandem Vibratory Rollers offer unobstructed sight lines with standard 180° seat positioning and ability to rotate 360° for excellent all-around visibility. Also, drum edge and drum surface lighting provide better lighting for nighttime operation. The innovative handwheel steering technology eliminates the front console that is commonly found on other machines for precise machine control.

Split Drum Design

The exclusive split-drum design delivers excellent mat quality in urban environments when frequent turning is required. When turning, the outside drum half rotates faster than the inside drum, eliminating the potential for shoving and tearing that occurs on standard vibratory drum designs. The exclusive axle-type pod design utilizes tapered roller bearings that support each drum half and eliminates any potential for contact between the two halves.

Dual Amplitude/Dual Frequency Vibratory System

The dual amplitude, dual frequency vibratory system can be tailored to thin and thick lifts. A single switch automatically matches amplitude and frequency for simple operation.

Performance Features

The vibratory system offers multiple options that help fine-tune performance. 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.
Cat® Compaction Control
The optional Cat Compaction Control helps contractors increase efficiency and productivity while recording data for quality control documentation and future planning.

Cat® C3.4B Engine

The C3.4B engine provides 75 kW (102 hp) of power and meets U.S. EPA Tier 4 Interim and EU Stage IIIB emission standards. 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. Two high volume fans direct warm air away from the operator for a more comfortable operating environment.
Smooth Operating Powertrain
The B-Series tandem rollers are powered by Cat® engines with ACERT™ Technology. The engine includes a variety of features that help reduce fuel burn, including ECO-mode, yet still deliver the power required on challenging jobsites. Tough components help extend compactor life.
