Tandem Vibratory Rollers

Cat CB2.7 GC utility compactor

Caterpillar has introduced 10 new tandem and combination utility compactors.

The new line includes the following weight-based model nomenclature changes:

  • The Cat CB2.5 and CB2.5 GC replace the CB22B
  • CB2.7 and CB2.7 GC replace the CB24B
  • CC2.7 and CC2.7 GC replace the CC24B
  • CB2.9 replaces the CB32B
  • CB4.0 replaces the CB34B
  • CC4.0 replaces the CC34B
  • CB4.4 replaces the CB36B.

These rollers are designed to take on a range of soil and asphalt applications, including parking lots, driveways, urban streets, landscaping, and small construction sites.

The new Cat CB2.5, CB2.7, CC2.7, CC 2.9, CB4.0, CC4.0 and CB4.4 models feature a Cat C1.7T engine the meets Tier 4-F. Advanced hydraulics and exclusive power management software combine to deliver performance on grades. The new auto idle shutdown feature helps to conserve fuel and hours.

Designed for rental and low- to medium-duty applications, the Cat GC series compactors are made to deliver low total cost of ownership, simplified maintenance, and long-term durability.

Powered by a turbocharged Cat C1.7T engine rated at 24.6-horsepower, the CB2.5 GC, CB2.7 GC, and CC2.7 models meet Tier 4-F emission standards without an aftertreatment system. They are aimed at low- to medium-grade applications like driveways and parking lots.

The re-engineered operator controls feature simple rocker switches and an easy-to-read Cat display for intuitive operation. One switch controls low/high vibration frequencies, while auto vibration control ceases vibration when the travel lever is in neutral to prevent marking of the asphalt mat. Available dual propel levers help to improve operator comfort. 

Offering compaction widths from 39 inches to 54 inches, all new Cat utility compactors feature large drum diameters for a smooth mat finish and thick drum shells for added durability, the company says. The rollers’ 2-inch drum offset improves compaction efficiency when rolling next to curbs. A narrow frame design allows for improved visibility to the job surface and drum edge. Optional compaction measurement value (CMV) displays measured material stiffness to the operator, improving compaction performance, eliminating unnecessary passes and improving consistency.

Both the standard and GC series models incorporate a water tank gauge for continuous monitoring from the operator’s station, so the tank does not run dry. Better positioned nozzles on the spray bars improve water coverage on the drum to prevent material pick-up. A spray test mode on the water system facilitates testing and adjusting nozzle angle to ensure proper drum coverage.
