Vibratory System

An industry-proven eccentric weight design combined with high amplitude and frequency delivers superior compaction in the fewest number of passes.

High Centrifugal Force and Amplitude

High centrifugal force and amplitude provides superior compactive effort and exceptional productivity.

Vibratory Frequency

A vibratory frequency of 35 Hz (2100 vpm) combined with optimal drum weight enables the machine to achieve density in fewer passes

Heavy-duty Bearings

The large heavy-duty bearings for the weight shaft are designed for high compactive forces.

Bearing Lube Service

A 1000 hour vibratory bearing lube service interval reduces maintenance.

Heavy-duty Isolation Mounts

Heavy-duty isolation mounts allow more force to be transmitted to the ground and less vibration to the drum yoke.

Cat C3.4B Engine

The Cat C3.4B Engine is efficient, powerful and meets US EPA Tier 4 Final and EU Stage IV emission standards. It provides 55 kW (74 hp) of gross power.

Propel System

The efficient propel system of the CP34 provides high tractive effort and gradeability for outstanding productivity, machine control and utilization.

Dual Pump Propel System

The CP34 features the proven Cat dual pump propel system, provides dedicated hydraulic flow to both the front drum axle and the rear wheel axle for excellent traction and power, even in extreme conditions or on steep grades.

Limited Slip Differential

The limited slip differential provides balanced tractive effort and smooth torque transfer to both rear wheels.

Infinitely Variable Speed Range

The CP34 has infinitely variable speed range for maximum torque when using the leveling blade or grade climbing, plus the ability to move quickly over longer distances.

High Travel Speed

High travel speed up to 8.9 km/h (5.5 mph).

Operator's Station

The operator's station is designed for simple control, comfort and productivity. The platform is equipped with a ROPS/FOPS canopy and is enclosed by handrails and features foot rests for sure footing.

Single Lever Control

Single lever control for propel and vibratory On/Off provides simple and low effort operation.

Propel Lever

The easy to reach propel lever is located to the right of the operator's seat for convenient and accurate machine control.

LCD Screen

Operational gauges and basic diagnostics are displayed on an LCD screen integrated with the right side operator's console.


Visibility is unrestricted to the drum and tire edge and to the side and rear of the machine.

Operator's Seat

The operator's seat is comfortable, durable and adjustable with flip-up arm rests and a 76 mm (3") wide retractable seat belt.

Isolated Operator's Station

The operator's station is isolated with heavy-duty rubber mounts to reduce machine vibration transmitted to the operator.

Compact Size for Specific Applications

The compact size of the CP34 is designed specifically for utility construction with narrow working widths like trench compaction or job sites with limited space.

Narrow Machine Width

The narrow machine width of 1.39 m (4'6") is ideal for working in trench applications or job sites with limited space.

Machine Weight

The machine weight is good for light compaction of uniform layers over sewer and water pipes.

Propel System

The propel system allows the operator to stop, maintain machine position and change directions while on a grade.

Turning Radius

The CP34 has a short turning radius for good maneuverability in confined work areas.

Padfoot Drum

The padfoot drum features involuted pads in shape to walk out of the lift without fluffing or "kicking up" the soil around the pads. Pads are tapered to help clean themselves. Heavy-duty scrapers mounted on the front of the drum are individually adjustable and replaceable and help to reduce excessive material build up between the pads.

Leveling Blade

The leveling blade increases the versatility and utilization of the machine, plus greatly enhances productivity.

Expands Machine Versatility and Utilization

The optional leveling blade expands the machines versatility and utilization for use in material knockdown, site leveling, trench backfilling and light dozing applications.

Single Lever Blade Control

Single lever blade control is located to the right of the operator’s seat for simple and convenient operation.

Efficient Propel System Combined with Ample Engine Horsepower

Efficient propel system combined with ample engine horsepower provides plenty of power and tractive effort for effective blade use without drum spin.

Cutting Edges

The two-piece reversible and replaceable cutting edge increases edge service life and reduce replacement costs.

Mounting Point

The high mounting point provides superior curb and obstruction clearance.

Reliability and Serviceability

Reliability and serviceability are integrated into every Cat Soil Compactor. These important features keep your machine investment profitable.

Visual Indicators

Visual indicators allow easy check of radiator coolant, hydraulic oil tank level and air restriction indicator.

Operator’s Station and Platform Tilts

The operator's station and platform tilts forward to allow convenient access to the hydraulic pumps.

Cooling System

A rear mounted cooling system provides easy access for cleaning.

500 hour engine oil change interval.

Vibratory Bearing Lube Service

The 1000 hour vibratory bearing lube service interval reduces maintenance.

Quick-connect Hydraulic Test Ports

Quick-connect hydraulic test ports simplify system diagnostics.

Ecology Drains

Ecology drains provide an environmental method to drain fluids. They are included on the radiator, engine oil pan, hydraulic and fuel tank.

Scheduled Oil Sampling (S•O•S) Ports

Scheduled Oil Sampling (S•O•S) ports allow for simple fluid collection of engine oil, engine coolant and hydraulic oil.

Secure Hose Routing

Secure hose routing with polyethylene blocks reduce rubbing and increase service life.

Electrical System

Nylon braided wrap and all-weather connectors ensure electrical system integrity. Electrical wiring is color-coded, numbered and labeled with component identifiers to simplify troubleshooting.

Maintenance-free Cat Batteries

Maintenance-free Cat batteries are mounted in the rear of the machine are accessible through the swing out rear grill. Cat batteries are specifically designed for maximum cranking power and protection against vibration.

Product Link Wire-ready

Machine is Product Link wire-ready. The Cat Product Link System (CPLS) ensures maximum uptime and minimum repair costs by simplifying tracking of equipment fleets. provides automatic machine location and hour updates. can be obtained through your local Cat dealer.
