Cat’s compactors are shot of slam and wedge weights

This provides longer service life than competitive systems, which incorporate heavy weights that slam and wedge together, causing metal chips that contaminate the system. Direction of weight shaft rotation determines high or low amplitude.
The pod is a sealed chamber inside which the eccentric weight spins. The pod is assembled and sealed in a “clean room” and has double seals to help guard against contamination once installed. Replacement is much easier: the pod can be exchanged while the drum stays horizontal.
The CS44 and CP44 units share many of the same industry-proven designs and performance features of 400E soil compactors. But they feature increased serviceability, reliability and operator comfort to compete successfully in the 5.5 to 8t machine class.
Dual pump
Both feature Cat’s exclusive dual pump propel system. It provides separate hydraulic flow to the rear wheels and the drum, for exceptional tractive effort in soft conditions or on steep slopes, and allows for superior control on a grade in forward and reverse.
The two pumps independently provide hydraulic flow to the drum drive and wheel drive motors, so there is maximum torque and full-time tractive power, regardless of traction or rolling resistance. A limited slip diff is standard on all models and top speed in forward and reverse is 12.3km/h. The drum provides superior manoeuvrability.
The new 75kW Cat® C4.4 engines with ACERT™ technology, feature a thicker engine block and more-robust components to reliability and reduce noise.
Improved engine airflow design, vents engine heat at the rear of the machine. This helps prevent the exhaust blowing ground-level debris, or heat on the operator. The cooling system is also 25% larger than the system on the previous 433E.
Tilting column
The operator’s station features a tilting steering column that also moves out of the way for easy entrance and exit and more leg and knee room. Gauges are clustered on the steering column.
The propel lever and parking brake switch are to the right of the operator’s seat. Grouped controls feature a height adjustable, padded wrist rest. An optional foot-operated leveling blade is available for the CP44 and padfoot shell kit-equipped CS44s.
The suspension seat is fully adjustable to include fore and aft positions, bottom cushion height and suspension stiffness. Flip-up armrests and a 76mm wide retractable seat belt are standard. A rotating seat is optional.
A bolt-on, two-post ROPS/FOPS canopy or a ROPS/FOPS cab is available. These configurations may be standard in some market areas and optional in others. Factory installed air conditioning is similarly available.
Four large isolation mounts isolate the operator platform from the machine frame for reduced vibration transfer, while improved operator visibility and excellent service access are achieved with a new, sloped, fibreglass rear hood. It allows visibility of 1m high and 1m wide obstacles to the rear of the machine.
Dual amplitude
Dual amplitude is standard on the CS44 and CP44. Maximum centrifugal force in high amplitude is 134kN and 67kN in low. The large spread between the two makes it easier to adapt compactive effort to changes in lift thickness, soil characteristics and density requirements while maintaining top performance.
Because of the decreased risk of contamination and the use of synthetic oil, the change interval for the bearing lubrication oil is best-in-class at 3 years/3000 hours. Scheduled oil sampling is not necessary.
Optional vibration per minute (VPM) gauge and variable vibration frequency enhance the productivity of the CS44 and CP44 compactors.
Other options include: a two-piece padfoot shell kit for the CS44; polyurethane scrapers on the front and rear of the drum on the smooth drum models, a foot-controlled leveling blade for the CP44 and padfoot shell kit equipped CS44s, bio-oil factory-fill option, a rotating suspension seat and a brake release pump.
Service access
Service access is simple and convenient on the CS44 and CP44. The durable one-piece fiberglass hood tilts forward with the aid of two gas charged struts. Once the hood is opened, the engine compartment and cooling package are accessible.
The operator’s station tilts forward to provide access to the hydraulic pumps, hoses and electrical components. A hand-operated hydraulic pump is standard on machines equipped with a cab and optional on machines equipped with a platform. The hydraulic pump operates a hydraulic cylinder to raise and lower either the operator’s platform or cab.
The hydraulic system has an improved test-port block to simplify oil sampling and prevent accidental oil spilling or contamination of the hydraulic system. The CS44 and CP44 come from the factory with a standard fill of Cat HYDO™ Advanced 10 hydraulic oil, which extends the hydraulic system maintenance interval to 3 years/3,000 hours. This is the longest available for this class of machine. Hydraulic pumps and motors common with other Cat equipment make servicing easier for mechanics.
