Caterpillar® C2.2 EngineThe C2.2 engine provides efficient power while meeting EU Stage IIIa engine emissionrequirements.

Power. The liquid cooled Caterpillar C2.2 engine providesa gross power of 34.1 kW (46 hp) and a torque of 143 Nmfor excellent performance and reliability on grades and intough conditions.

Large Cooling Package. The large cooling package withintegrated water and oil cooler keeps engine temperatureslow in order to maximize fuel efficiency and minimizeemissions.

High Ambient Cooling Option. The high ambient coolingprovides capability to achieve greater production rates athigh ambient temperatures.

Reduced Sound Levels. Low sound levels are achieved inboth operating speeds. An intermediate throttle positionenables even quieter operation for optimum operatorcomfort.

Vibratory SystemThe vibratory system provides good balance between frequency and amplitude in order tomeet various job site conditions.

Dual Frequency Vibratory System. The standard vibratorysystem incorporates two frequencies in order to provideincreased application versatility.

Vibration Selection. A vibratory selection switch providesstandard front, rear and both drum vibratory capabilities.

Automatic Vibratory Control. The vibratory systemincludes an automatic start feature that activates wheneverthe propel lever is moved from the neutral position.

Rear Drum Vibe Delay. The vibe delay function controlsthe start of the rear drum in order to assist powermanagement on slopes.

Pod-style weight housings. They are assembled and sealedat the factory to ensure cleanliness, extended bearing lifeand easy field exchange/service.

Bearing lubrication. Change interval for bearinglubrication is every 3 years or 3000 hours.

Operator’s StationThe convenient, comfortable operating environment with sliding seat provides good visibilityand promotes day-long productivity.

Operator’s Station. The operator’s station incorporates a fully-equipped console and an adjustable slidingsuspension seat. Arm and wrist rests provide betteroperator comfort for day-long productivity. The steeringwheel includes a steering knob for easy maneuverability inturns.A 12-volt outlet for plugging in personal electronicdevices is also included.

Instrument Panel. The easy-to-understand instrumentpanel cluster integrates a fuel level indicator, hour meterand light indicators for machine functions.The key switchincludes an automatic engine pre-heat feature in order toassist in cold-weather starting.

Smooth Operation. The hydraulic propel lever’s two stepregulating curve provides smooth and precise control atlow speed. Machine speed increases gradually in the firsthalf of lever stroke for optimum control in confined areas.The second half of lever stroke enables maximum transferspeed to be reached rapidly.

Foldable ROPS (optional). The foldable ROPS includestwo gas struds that assist the operator when raising orlowering for transport. The ROPS structure foldsbackwards and does not require special tools.

Unobstructed visibility. Sloped engine enclosure, lowprofile rear end and sliding operator's station provideunobstructed visibility to the drum edges or wheel contact points.

Water Spray SystemCorrosion-proof system and extended-life components provide reliable operation.

Water Tank. A 300 liter high-capacity polyethylene watertank is enclosed within the machine frame. The tank designprovides extended operation and a single fill point.

Spray Capabilities. The standard pressurized water spraysystem with constant or intermittent capabilities providesextended operation between refills.

Water Pump and Filters. The extended life water pump andfilters are conveniently located for easy access whileproviding optimum spray and flow.

Water Filtration. Triple water filtration reduces machinedowntime caused by system clogs.

Large Water Tank Fill and Drain. The large water tank filland grouped drains allow the system to be filled and drainedwithin minutes.

Spray Nozzles and Filters. Water spray nozzles and filtersare easily removed by hand without the need of specialtools.

Tyres Enhance Versatility – CC34The CC34 incorporates a steel, front drum with rear pneumatic tyres. The pneumatic tyresprovide even compaction on uneven surfaces.

Front drum and rear rubber tyres. Steel front drum andrubber tires at the rear allow a single machine to function as both a double drum and pneumatic compactor.

Rubber tires. Four rubber tyres (10.5/80 - 16 6-ply)generate a high ground contact pressure that penetratesdeep into the lift.

Flexible tires. Because the tyres are flexible, horizontalpressures develop, assisting with compaction.

Adjustable scraper. Each tyre is fitted with a replaceable,adjustable scraper. The scrapers can be positioned above the tyres when they are not needed.

Emulsion Filing Port. The emulsion filling port is locatedat the rear of the machine and can be accessed withoutopening the rear hood.

Extra Wide Drums – CB34 XWWider drums on the CB34 XW provide increased production results on larger job sites.

Increased Production. The CB34 XW is equipped with1400 mm wide drums and can cover greater mat widthsin fewer overlapping passes. The rolling pattern changeswith an increased production.

Increased Amplitude. Wider drums, increased amplitudeand dual frequency balanced with the amplitude settingmakes this machine an excellent choice of machinery onthin asphalt lift mats and larger job sites.

Optional tyre spray systemcontrol activates the solventsprayed to prevent asphalt fromadhering to the tyres surface.

ServiceabilityThe CB34, CB34 XW and CC34 machines provide the reliability and serviceability thatyou’ve come to expect from Caterpillar.

Engine Enclosure. Fiberglass engine enclosure pivotsupward and locks open with a prop rod.

Vibe Lubrication. Oil-bath lubrication of eccentric weightbearings reduces routine maintenance to 3 year/3000 hourintervals.

Service Points. External engine components, hydraulics androutine service points are clustered in easy-to-accesslocations.

Oils. Extended-life oils increase maintenance intervals for the vibratory system, hydraulic system and engine oil.Engine oil change interval has been extended to 500 hours.

Drains. Remote-mounted drains for engine, hydraulic oiland cooling system provide simplified collection of fluids.

Hydraulic Test Ports. Quick-connect hydraulic test portssimplify system diagnosis.

Electrical System. Electrical wiring is color-coded andnumbered for simple troubleshooting. Nylon-braided wrapand all-weather connectors ensure electrical systemintegrity.
