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.
When activated, Eco-mode reduces the operating speed of the engine to a lower rate, which reduces fuel consumption. Eco-mode can be engaged on most applications where operating conditions require normal engine power. When more power is required, Eco-mode can be deactivated to provide normal engine speed.
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.
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 CS44B provides high productivity when working on more demanding grades. These machines are very effective in trench applications.
The steering console adjustables within the tilt range to the desired position of the operator. Entire console tilts for simple entrance and exit. Integrated cupholders provide convenient storage for beverage containers.
The operator's console is integrated with the seat and houses operational controls, the propel lever, and an integrated LCD display. The LCD display functions as the gauge cluster and also provide diagnositics. The keypad is backlit to facilitate easy operation in low light conditions.
Single Lever Control
Single lever control for propel and vibratory On/Off provides simple and low effort operation.
The comfortable and durable seat has adjustable fore/aft position, bottom cushion height, suspension stiffness and an integrated control console for maximum comfort.
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 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.
Two Available Pad Designs
Two padfoot designs are available: oval and square. The exclusive Cat oval padfoot design provides deeper penetration into the lift to ensure compaction from the bottom of the lift to the top. The square pad design provides less lift penetration but does an excellent job of sealing the surface.
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.
Visual indicator allows easy check of hydraulic oil tank level.
Air Restriction Sensor
A sensor monitors engine air flow and alerts operator to restriction via the LCD display.
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.
Sealed-for-life bearings in the articulation hitch never need to be greased.
500 hour engine oil change interval.
500 hour engine oil change interval.
Vibratory System Lubrication Service
A 3 year/3000 hour vibratory bearing lube service interval reduces maintenance.
Hydraulic System Oil Service
A 3 year/3000 hour Hydraulic System oil service interval reduces maintenance.
Quick Connect Hydraulic Test Ports
Quick connect hydraulic test ports simplify system diagnostics.
Provide a method to drain fluids that is more environmentally safe. They are included on the radiator, engine oil pan, hydraulic tank and fuel tank.
S•O•S (Scheduled Oil Sampling) ports
S•O•S ports allow for simple fluid collection of engine oil, engine coolant and hydraulic oil.
Secure Hose Routing
Hose routing is secured with polyethylene routing blocks to reduce rubbing and increase service life.
Electrical System Integrity
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 and are protected by the engine hood. Cat batteries are specifically designed for maximum cranking power and protection against vibration.
Product Link Wire-ready
The CS44B is Product Link wire-ready. Product Link ensures maximum uptime and minimum repair costs by simplifying tracking of equipment fleets. The system provides automatic machine location and hour updates. The system can be obtained through your local Cat dealer.
