Sales Features

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.

Drum Steer Features

The drum steer machines can offset the drums up to 1.3 m (51") to provide more coverage for higher production on thin mats while minimizing heat loss prior to compaction. Ease of operation is provided through fingertip control at the propel lever and an audio alarm alerts the operator when the drums are aligned.

Cat® Compaction Control

The optional Cat Compaction Control helps contractors increase efficiency and productivity while recording data for quality control documentation and future planning.

Vibratory System Choices

Cat Tandem Vibratory Rollers quickly reach target densities due to their versatile frequency and amplitude selections. These powerful rollers also provide finesse when necessary due to their flexible front or rear drum only vibratory capability. Options include dual amplitude/dual frequency and five amplitude systems.

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, yet still deliver the power required on challenging jobsites. Tough components help extend compactor life.
