Pod-style Weight Housing
The pod-style weight housing is assembled and sealed at the factory to ensure cleanliness, longer bearing life and easier field exchange or service.
The dual amplitude works efficiently in a wider range of applications. Selection is controlled from the operator's station.
The CS44 has a vibratory frequency of 31.9 Hz (1914 vpm) for maximum compaction results. An optional variable frequency control allows frequency to be better matched to varying job conditions.
Large Heavy-duty Bearings
Large heavy-duty bearings for the eccentric weight shaft allow higher frequency for greater force.
3 year/3000 hour
The 3 year/3000 hour vibratory bearing lube service interval reduces maintenance.
The heavy-duty isolation mounts on the CS44 allow more force to be transmitted to the ground and less vibration to the drum yoke.
Positive Amplitude Selection
Positive amplitude selection is accomplished when the spherical steel shot is repositioned inside the hollow eccentric weight. Direction of weight shaft rotation determines amplitude level.
Control is simplified from the operator’s station with a selection switch on the operator’s console.
The proprietary eccentric weights offer high reliability since there is no chance of the high-strength spherical steel shot welding together. System reliability is superior to swinging mechanical weights and is also quieter during starts and stops.
The proprietary eccentric weights offer long service life. There are no heavy weights to slam together and no metal fragments to contaminate the bearing lubrication system.
ACERT Technology combines proven systems with innovative new technologies to precisely shape the combustion process, providing more complete combustion of fuel and lower emissions.
More Robust Block and Components
The C4.4 has been built with a thicker engine block and more robust components, improving durability and reliability while helping to keep noise levels low. The robust design also contributes to improved cold-weather starting performance.
Engine Oil Cooler
The cooling package has been increased in size by 25%, reducing oil deterioration and varnishing of internal components as well as operating temperatures. Engine oil change interval is every 500 hours.
Low-mounted Oil Pump
The positioning of the oil pump provides quick start-up lubrication, ensuring less engine wear and a longer engine life.
Engine Certified to Meet Emissions Standards
The C4.4 engine is certified to meet U.S. EPA Tier 3 and European EU Stage IIIa emissions standards.
Dual Propel Pumps
The dual propel pumps provide separate, balanced flow to the rear wheel axle and the drum drive motors. Provides high gradeability and increases tractive effort in loose or poor underfoot conditions.
Limited Slip Differential
The limited slip differential provides balanced tractive effort and smooth torque transfer to both rear wheels.
Two Speed Ranges
The dual pump propel system offers two speed ranges for versatile operation. Low speed range for vibratory operation and maximum torque when climbing grades. High speed range moves the machine quickly over longer distances.
Flushing valves in each propel circuit help keep hydraulic oil cool and clean for maximum system efficiency.
Two Propel Pump System
The two propel pump system has dedicated pumps to drive the heavy-duty, high-torque rear wheel and drum motors independently. Should the drum or wheels begin to spin, there is always hydraulic flow to the non-spinning motor, allowing continuous tractive effort. This is especially useful in loose underfoot conditions.
Controllability is another feature of dual propel pumps. The operator is able to stop, maintain machine position and change directions while on a grade.
The CS44 provides high productivity when working on more demanding grades. These machines are very effective in trench applications.
Visibility to the tire edges and rear of machine is exceptional. The sloped hood allows the operator to see obstacles measuring 1 meter (3' 3") high located 1 meter (3' 3") to the rear of the machine. Excellent visibility in all directions increases productivity when working near obstructions or maneuvering around the job site.
Lockable Engine Hood
The lockable engine hood opens quickly and easily with the use of gas struts to provide good access to the engine, cooling system and all service points.
Low sound levels for the operator and the ground crew due to the engine hood and cooling air flow through the rear mounted radiator.
The open platform of the CS44 offers a spacious and comfortable working environment with all controls, levers, switches and gauges positioned to maximize productivity.
The open platform offers unrestricted visibility to the drum and tire edge and to the side and rear of the machine.
Handrails and Foot Rests
The platform is enclosed by handrails and features foot rests for sure footing and support when working on a grade.
Standard equipment includes two front-facing and two rear-facing working lights, handrails with footrests, a lockable vandalism guard and a rear view mirror.
Steering Console and Operational Gauges
The steering console and operational gauges are infinitely adjustable within the tilt range to the desired position of the operator. Entire console tilts for simple entrance and exit.
Single Lever Control
Single lever control for propel and vibratory On/Off provides simple and low effort operation. A padded adjustable wrist rest helps reduce operator fatigue.
The comfortable and durable seat has adjustable fore/aft position, bottom cushion height, suspension stiffness and flip-up arm rests.
Isolated Operator’s Station
The operator's station is isolated with heavy-duty rubber mounts reducing machine vibration transmitted to the operator.
A floor mat helps further isolate the operator from machine vibration and noise.
The cab is a spacious and comfortable work environment that includes large windows, more interior room with storage areas, a cup holder, better ergonomics and low noise levels.
Full-length Glass Windshield
The full-length glass windshield provides exceptional visibility to the drum and optional leveling blade.
Mirrors and Lights
Included with the cab are two exterior rear view mirrors, front and rear working lights and cab lift cylinder.
Windshield wipers on the front and rear windows allow good vision in adverse conditions.
Side windows slide open for cross ventilation.
The cab is climate controlled with standard heater/defroster as well as air conditioning to keep the working environment comfortable.
Expands Machine Versatility
The padfoot shell kit expands the machines versatility and utilization while providing a simple and cost-effective solution for jobs that may require both padfoot and smooth drum compaction.
A dual-purpose bumper is also included with the shell kit and does not need to be removed once installed.
The bumper also provides adjustable scraper teeth for use with the padfoot shell kit and adjustable scraper plates for use with the standard smooth drum. When the scraper plates are not being used, they can be bolted onto the front of the bumper for convenient storage.
Two-piece Shell Kit
The padfoot shell halves can be quickly and easily installed or removed in about an hour with the use of an approved lifting device. The two-piece shell kit features a total of 98 pads with a pad height of 90 mm (3.5").
Expands Versatility and Utilization
The leveling blade expands the machines versatility and utilization for use in material knockdown, site leveling, trench backfilling and light dozing.
Leveling blade control is controlled by the operator’s right foot to provide simple, one-handed operation of machine propel, steering and blade functions simultaneously.
Power and Tractive Efforct
The dual propel pumps provide plenty of power and tractive effort for effective blade use without drum spin.
No special permits are required for transporting with a blade width of 2.12 m (6' 11").
Two-piece reversible and replaceable cutting edges increase edge service life and reduce replacement costs.
High Mounting Point
The high mounting point provides superior curb and obstruction clearance.
Visual indicators allows easy check of radiator coolant, hydraulic oil tank level and air restriction indicator.
Operator’s Station Tilts Forward
The operator's station tilts forward to allow convenient access to the hydraulic pumps.
Rear Mounted Cooling System
The rear mounted cooling system provides easy access for cleaning. The hydraulic oil cooler tilts rearward for additional access to the radiator.
