CW34 Pneumatic Roller

CW34 Pneumatic Roller

The CW34 is an eight wheel pneumatic roller that features a modular ballast system and flexible operating weight of 10 000 kg to 27 000 kg (22,050 lb – 59,525 lb). This machine offers excellent visibility, ECO-mode operation, even compaction, and excels on a variety of materials due to its flexible air-on-the-run capability.

Versatile Compaction Performance

Versatile Compaction Performance due to the flexible ballast system, oscillating front wheels, and optional air-on-the-run. Flexible ballast options include modular and non-modular steel, sand, and water. The modular steel ballast system can be easily added or removed, making it easy to adjust operating weights and match job site requirements.

Compaction Width

Eight 13/80 R20 rubber tires provide overall compaction width of 2090 mm (82") with 25 mm (1") overlap.

Flexible Ballast

Ballast options include modular and non-modular steel, sand, and water. The 6.5 metric ton (7.1 U.S. ton) modular steel can be easily added or removed through bolt-on side panels. The internal, non-modular steel consists of 6.1 metric tons (6.7 U.S. ton). Also, a 3 cubic meter (793 gal) water-tight chamber with baffled compartments prevent surge, and balance weight.

Oscillating Tires

Oscillating front and rear tires deliver vertical and horizontal forces that reduce air voids, providing surface uniformity. Heat retention covers trap heat to keep the tires warm and prevent pick-up. They can be easily stored when not in use.

Air-on-the-Run

The 13/80 R20 rubber tires can be equipped with the optional air-on-the-run system that enables the operator to quickly adjust tire pressures to increase or decrease static loads for optimal surface quality.

Exceptional Visibility and Control

Exceptional Visibility and Control with sliding and rotating operator’s station, LCD display, touch-pad machine functions, and optional Compaction Control. This machine can be equipped with a Cab or ROPS.

Operating Environment

The sliding and pivoting operator station rotates 90° to either side for ultimate comfort and control. The new console design includes an LCD display and push button machine controls that simplify operation for an all-around comfortable operating environment.

Cat® Compaction Control

Cat® Compaction Control keeps the operator informed for higher performance and efficiency. Infrared temperature sensors combined with mapping keep the operator informed of when optimal conditions exist and where compaction has taken place. Temperature Mapping records data for future analysis, while Pass-Count Mapping keeps the operator informed of the number of passes made.

Dual Infrared Temperature Sensors

Dual infra-red sensors mounted on the front and rear of the machine deliver real-time readings that keep the operator informed of when to begin rolling and when to stop. This system helps operators avoid tender-zones that often occur in the 104º-110º C (219º-230º F) temperature range.

Pass-Count Mapping

Pass-count mapping helps operators achieve target density and increase roller efficiency. The system records and monitors pass patterns in order to display coverage. The system also helps operators optimize drum overlap, simplify nighttime operation, eliminate second guessing and prevent incomplete passes such as stopping short.

Temperature Mapping

Temperature mapping provides a visual readout of mat temperature in order to keep the machine in the proper temperature range. The system records and monitors temperature for future analysis of the proper temperature range.

Smooth Operating Powertrain

Smooth Operating Powertrain with electronic propel control and smooth braking system. The three speed hydrostatic propel system delivers excellent gradeability with speeds up to 19 km/hr (11.8 mph).

C4.4 Engine

The C4.4 engine meets U.S. EPA Tier 4 Interim and EU Stage IIIB emission standards and provides 98 kW (133.2 metric hp).

ECO-mode

Standard ECO-mode provides fuel efficiency and reduces sound levels.

Best Lifetime Value

Best Lifetime Value with ECO-mode operation, efficient engine, and durable rubber tires minimize life-time operating costs and maximize profit.
