Cat launches trio of tandem vibratory rollers

Caterpillar has added three new tandem vibratory rollers to its family of paving machines.

The new models are the CB13, CB15, and CB16, with the numbers corresponding to the 13-, 15- and 16-ton weight classes they reside in.

The company says that the new models can be equipped with an oscillatory vibration system for versatility, and offer refinements to the operator controls, water spray system, service access, and lighting packages.

Technological enhancements are provided through the Cat Compaction Control option. Pass-count and temperature mapping systems combine infrared temperature sensors with GPS mapping to keep the operator informed of current mat temperatures, machine position and and pass coverage, as well as the pass-count. Caterpillar says that the system greatly enhances night-time rolling pattern performance, and records information for future analysis and quality control documentation. Drum edge and drum surface lighting can be used to help extend the workday and increase production by optimizing people’s awareness in low-light conditions.

“Machine to machine” communication is another technological enhancement designed to improve efficiency. The system helps keep rolling patterns in sync by sharing mapped data such as temperature mapping, coverage area and pass-count maps between the displays of multiple machines.

A 360° seat positioning option enables the operator to keep facing the direction of travel.

The compactors offer a variety of vibratory options including oscillatory vibration, dual amplitude, dual frequency, five-amplitude and Cat’s Versa Vibe systems. The Versa Vibe system creates a 2-in-1 machine with four amplitudes and two frequencies. This system provides two settings for lighter hitting and higher working speeds on thin lifts; and two settings for heavier hitting and slower speeds, on thick lifts or those with challenging mixes. The five-amplitude system offers the widest range of amplitudes with a single frequency, while the two-amplitude, two-frequency system offers simple thin lift or thick lift compaction with the flip of a switch.  

The design combines Caterpillar’s vertical vibration on the front drum with oscillation technology on the rear drum. The front drum with vertical vibration is available in two-amplitude, five-amplitude, or Versa Vibe systems.

The oscillatory system uses the pod-style eccentric weight technology developed by Caterpillar and has a two-year/2,000-hour service interval.

The models feature a newly designed center-articulating hitch with 6° degrees of oscillation designed to ensure mat contact and a smoother ride over uneven surfaces. An offset hitch option extends coverage up to 6" and simplifies control next to obstacles such as curbs and gutters.
