CB2.7 GC

Get it dense and keep it smooth. Cat Tandem Vibratory Rollers do that and more. Caterpillar offers a vibratory system for every application. Most models have high frequency combined with low amplitude that match high paving speed on thin lifts as well as low frequency with high amplitude that match low paving speed on thick lifts of stiff material. As stand-alone units or as complements to high production tandem rollers, Cat Utility Rollers set the standards for versatility and reliability. A wide range of drum widths lets you precisely match the machine to the job requirements—whether it's a narrow shoulder, a patching project, a parking lot or a bicycle path. Vibratory systems are characterized by high frequency for fast working speed and high compaction energy for getting density in the fewest passes.

Sustainability

The Cat® C1.7T engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester)** or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
Auto engine idle shutdown helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
A well-trained operator is worth the investment. Skilled operators benefit your bottom line by maximizing productivity, avoiding costly downtime, and maintaining jobsite safety – which can help to improve fuel efficiency and reduce greenhouse gas emissions.
Extended maintenance intervals not only reduce downtime but can decrease the amount of fluid and filters that are replaced over the life of the machine. The hydraulic oil can be replaced every 3000 hours, eccentric housing oil can be replaced every 3000 hours, and engine oil changes can be 500 hours.
Cat Compact technologies help you consistently meet compaction targets faster, more uniformly, and in fewer passes - saving on fuel and reducing rework and material costs.
Cat Scheduled Oil Sampling (S•O•S?) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
Remote Flash for engines helps to minimize downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.
