Tandem Vibratory Rollers

Compacting to specifications is critical for soil, landfill, and paving applications. Cat compactors are specifically designed for all compaction operations.

CC34B Utility Compactor

The CC34B is a versatile machine that can be used as the only vibratory roller on small sized jobs or on larger jobs as a support roller for high-production rollers. The CC34B provides greater production capabilities with its 1200 mm (47") wide drum and 4 rear pneumatic wheels. Its high amplitude and drum width give it the capacity to achieve a tons-per-day production rate that make it an excellent match for shoulders, small parking lots, lane additions or other similar sized jobs.

Simple Operation

The operating environment offers improved comfort and visibility. The narrow frame design and contoured engine hood provide good visibility to the drum edges and front of the machine. The intuitive control panel utilizes a backlit LCD display and sealed switches with bright LED lights for easy recognition in a variety of operating conditions.

Intuitive Controls

Intuitive, multi-function control panel with vandal protection enables good performance. Easy viewing LCD Display and Vibrant LED lights on the control panel simplify operation in both day and night operation. Integrated vandal cover protects value.

LCD Display

Multiple language options are available for crew diversity. The display screen options include; engine speed, fuel level, hour meter, coolant temperature, hydraulic oil temperature, voltage. The default screen includes: engine speed, fuel level, hydraulic oil temperature and visual indicators to keep the operator informed of low water level (spray system), Eco-mode, drum selections, lights, water spray settings, traction control, regeneration, parking brake, and warning indicators.

Nighttime Operation

The bright LCD display and LED console lights optimize control for day and night operation. Roading and working lights include front lights with turn signals, a single rear working light with turn signals and a warning beacon.

Foldable ROPS and Canopy

Powerful lift cylinders enables a single person to raise and lower without the use of tools. A fixed ROPS is also available. The foldable canopy is compatible with fixed or foldable ROPS.

Efficient Compaction Performance

The vibratory system on the front drum is equipped with a variety of frequencies and single amplitude that provide lower sound levels and job site versatility. Four pneumatic tires located on the rear of the machine provide a kneading action for a tight mat finish.

Vibratory Drum and Rear Tires

The vibratory system is equipped with automatic vibration de-activation when the propel lever is in the neutral position. Vibration is available on the front drum. The exclusive eccentric weight shaft delivers quick starting and stopping times and a bearing service interval of 3 years or 3000 hours. Four pneumatic rear tires provide a kneading action for a tight mat finish.

Frequency Selection

Two frequency selections deliver excellent compaction performance and low sound levels. Selections of 55 Hz (3,300 vpm), and 48 Hz (2,880) are available.

Drum Offset Capability

A 50 mm (2“) drum offset capability enhances control near curbs and offers more coverage.

Best_In_Class Water Spray System

More coverage, and easier access: That summarizes the water spray system on Cat Utility Compactors. The result is less material pickup, and increased uptime for your crew.

Performance Enhancing Features

The protected spray bar is designed to fight winds, while a low water level indicator keeps the operator informed. A single water tank with a capacity of 262 L (69 gallons) provides more hours of operation between refills. The intermittent and continuous modes increase control and efficiency. Triple filtration in the tank, before the water pump, and in spray nozzles provides reliability. An antifreeze option provides protection in cold weather, while a single point to drain and filter water offers easy service.

Spring Loaded Scrapers

Spring loaded scrapers keep the drums clean and distribute water evenly for reduced consumption. Robust, retractable hinges help maintain contact with the drum and retract when roading to reduce unnecessary wear. Scrapers are located at the front and rear of each drum.

Optimized Power

Cat engines are the power behind Cat Utility Compactors. Optimized engine power provides the push you need on any project grade.

Powerful Cat Engines

Two engine offerings are available to meet local emissions requirements. An electronic control module (ECM) helps enable steady operation. The engine includes an electric fuel-transfer pump and fuel tank sized for 12-14 hours of runtime. Multiple engine speed settings enable operators to customize to the specific application and environment. Eco-mode can reduce fuel consumption up to 8 percent, depending on model.

Traction Control

A traction control option is available in a pin-on design that offers quick installation. Field retrofitting can be completed in an hour.

High Ambient Cooling

The cooling system provides ambient capability of 49°C (120°F) @ 80 percent load. The hydraulically driven fan motor enables variable speeds and reduces sound levels.

Designed For Rental

These new models are designed specifically for the rental market. The intuitive control panel and spacious platform offer comfort to suit a variety of operators. Durable components and fuel efficient engines maximize uptime and lower lifetime operating costs, while the Product Link capability enables close monitoring to keep owners informed of machine location and service needs.
