integrated water and oil cooler keeps engine temperatures
low in order to maximize fuel efficiency and minimize
emissions.
High Ambient Cooling Option. The high ambient cooling
provides capability to achieve greater production rates at
high ambient temperatures.
Reduced Sound Levels. Low sound levels are achieved in
both operating speeds. An intermediate throttle position
enables even quieter operation for optimum operator
comfort.
Vibratory System
The vibratory system provides good balance between frequency and amplitude in order to
meet various job site conditions.
Dual Frequency Vibratory System. The standard vibratory
system incorporates two frequencies in order to provide
increased application versatility.
Vibration Selection. A vibratory selection switch provides
standard front, rear and both drum vibratory capabilities.

includes an automatic start feature that activates whenever
the propel lever is moved from the neutral position.
Rear Drum Vibe Delay. The vibe delay function controls
the start of the rear drum in order to assist power
management on slopes.
Pod-style weight housings. They are assembled and sealed
at the factory to ensure cleanliness, extended bearing life

Operator’s Station
The convenient, comfortable operating environment with sliding seat provides good visibility
and promotes day-long productivity.
Operator’s Station. The operator’s station incorporates
a fully-equipped console and an adjustable sliding
suspension seat. Arm and wrist rests provide better
operator comfort for day-long productivity. The steering
wheel includes a steering knob for easy maneuverability in
turns.A 12-volt outlet for plugging in personal electronic
devices is also included.
Instrument Panel. The easy-to-understand instrument
panel cluster integrates a fuel level indicator, hour meter
and light indicators for machine functions.The key switch
includes an automatic engine pre-heat feature in order to
assist in cold-weather starting.

Smooth Operation. The hydraulic propel lever’s two step
regulating curve provides smooth and precise control at
low speed. Machine speed increases gradually in the first
half of lever stroke for optimum control in confined areas.
The second half of lever stroke enables maximum transfer
speed to be reached rapidly.
Foldable ROPS (optional). The foldable ROPS includes
two gas struds that assist the operator when raising or
lowering for transport. The ROPS structure folds
backwards and does not require special tools.
Unobstructed visibility. Sloped engine enclosure, low
profile rear end and sliding operator's station provide
unobstructed visibility to the drum edges or wheel
contact points.
Water Spray System
Corrosion-proof system and extended-life components provide reliable operation.
Water Tank. A 300 liter high-capacity polyethylene water
tank is enclosed within the machine frame. The tank design
provides extended operation and a single fill point.
Spray Capabilities. The standard pressurized water spray
system with constant or intermittent capabilities provides
extended operation between refills.
Water Pump and Filters. The extended life water pump and
filters are conveniently located for easy access while
providing optimum spray and flow.
Water Filtration. Triple water filtration reduces machine
downtime caused by system clogs.
Large Water Tank Fill and Drain. The large water tank fill
and grouped drains allow the system to be filled and drained
within minutes.
Spray Nozzles and Filters. Water spray nozzles and filters
are easily removed by hand without the need of special
tools.

Extra Wide Drums – CB34 XW
Wider drums on the CB34 XW provide increased production results on larger job sites.
Increased Production. The CB34 XW is equipped with
1400 mm wide drums and can cover greater mat widths
in fewer overlapping passes. The rolling pattern changes
with an increased production.
Increased Amplitude. Wider drums, increased amplitude
and dual frequency balanced with the amplitude setting
makes this machine an excellent choice of machinery on
thin asphalt lift mats and larger job sites.
Tyres Enhance Versatility – CC34
The CC34 incorporates a steel, front drum with rear pneumatic tyres. The pneumatic tyres
provide even compaction on uneven surfaces.
Front drum and rear rubber tyres. Steel front drum and
rubber 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 penetrates
deep into the lift.
Flexible tires. Because the tyres are flexible, horizontal
pressures 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 located
at the rear of the machine and can be accessed without
opening the rear hood.
Optional tyre spray system
control activates the solvent
sprayed to prevent asphalt from
adhering to the tyres surface.

Serviceability
The CB34, CB34 XW and CC34 machines provide the reliability and serviceability that
you’ve come to expect from Caterpillar.
Engine Enclosure. Fiberglass engine enclosure pivots
upward and locks open with a prop rod.
Vibe Lubrication. Oil-bath lubrication of eccentric weight
bearings reduces routine maintenance to 3 year/3000 hour
intervals.
Service Points. External engine components, hydraulics and
routine service points are clustered in easy-to-access
locations.
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 oil
and cooling system provide simplified collection of fluids.
Hydraulic Test Ports. Quick-connect hydraulic test ports
simplify system diagnosis.
Electrical System. Electrical wiring is color-coded and
numbered for simple troubleshooting. Nylon-braided wrap
and all-weather connectors ensure electrical system
integrity.

n
The scrapers help clean asphalt or soil
off the tyres. The scrapers can be
retracted when they are not needed.
n
An optional traction control device on
the rear tyres, activated by a foot
control from the operator's platform,
increases tractive effort and minimizes
drum spinning in slippery conditions.
Frame
Fabricated from heavy gauge steel plate
and rolled sections. The two sections are
joined by two hardened steel pins that
are supported by heavy-duty roller
bearings. A vertical pin provides a ±35°
steering angle and the frame/yoke
provides ±10° oscillation for a smooth
ride and uniform drum loading.
