Caterpillar's new Tandem Vibratory Rollers are the CB13, CB15, and CB16. New nomenclature corresponds to 13-, 15- and 16-ton weight classes. These models can be equipped with an oscillatory vibration system for application versatility and offer refinements to the operator controls, water spray system, service access, and lighting packages.
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 that provide initial compaction, while the rear drum with oscillation provides smoothness and density.
The oscillatory system utilizes the pod-style eccentric weight technology developed by Caterpillar and has a two-year, 2,000-hour service interval to maximize uptime and limit routine maintenance costs. A durable power-transmission employs a belt-drive system delivering twice the load capacity of timing belt systems for more reliable operation. In addition, the standard drum and optional hardened drum shells offer long-term life on a variety of mix designs and delivers mat texture, density, and smoothness.
These models feature a newly designed center-articulating hitch with 6 degrees of oscillation that ensures mat contact and a smoother ride over uneven surfaces. An offset hitch option extends coverage up to 6 inches and simplifies control next to obstacles such as curbs and gutters. It delivers excellent performance on longitudinal joints by pinching the edge with the lead drum and sealing the joint with the trailing drum.
The Cat C4.4 engine is rated at 142 hp and comes standard with Eco-mode and automatic speed control.
Visibility and comfort are enhanced by the 360-degree seat positioning option that enables the operator to always face the direction of travel. Handwheel steering technology eliminates the front steering console, enabling the operator to monitor water spray performance. A simplified eight-button control panel provides efficient control and performance.
