In March, Caterpillar announced the new CB13, CB15 and CB16 tandem vibratory rollers.

Through the Cat Compaction Control option, the new Caterpillar production-class tandem vibratory rollers include numerous technological enhancements.

In March, Caterpillar announced the new CB13, CB15 and CB16 tandem vibratory rollers, with the nomenclature corresponding to the 13, 15 and 16-ton weight classes.

Pass-count and temperature mapping systems combine infrared temperature sensors with GPS mapping to keep the operator informed of current mat temperatures, machine position, pass-count and pass coverage. The intuitive system enhances nighttime rolling pattern performance and records information for future process analysis and quality control documentation.

When combined with drum edge and drum surface lighting, Cat Compaction Control helps extend the workday and increase daily production by optimizing jobsite awareness in low-light conditions.

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

For comfort, the 360-degree seat positioning option enables the operator to always face the direction of travel. Handwheel steering technology eliminates the front steering console, enabling the operator to easily monitor water spray performance. A simplified eight-button control panel provides efficient control and performance.

The Caterpillar tandem vibratory rollers offer a variety of vibratory options including oscillatory vibration, dual amplitude, dual frequency, Versa Vibe and five amplitude systems. The Versa Vibe system creates a two-in-one machine with four amplitudes and two frequencies. This 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, thick lift compaction with the flip of a switch. These industry-proven vibratory systems are now complimented by the combination of vertical vibration in the front drum and oscillatory vibration in the rear drum.

The design combines Caterpillar’s high-performance 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 continues the excellent performance for optimal smoothness and density.

The oscillatory system utilizes the proven pod-style eccentric weight technology developed by Caterpillar and has a two year and 2000-hour service interval to help contractors maximize uptime and limit routine maintenance costs. A durable power-transmission employs a unique belt-drive system delivering two-times the load capacity of timing belt systems for more reliable operation.

As well, the standard drum and optional hardened drum shells offer exceptional long-term life on a variety of mix designs and delivers outstanding mat texture, density and smoothness.

The three models feature a newly designed centre-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 170 mm 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, rated at 142 hp, comes standard with eco-mode and automatic speed control, leading to uniform compaction, fuel savings and reduced sound levels to both operators and surrounding job site personnel.
