Caterpillar Inc. of Peoria (Illinois, USA) has announced a new addition to its line of compactors for asphalt agglomerate. The vibrating compactor of directional drum for asphalt agglomerate CD54 is a versatile machine that provides optimum results in all types of asphalt mixtures. From fine to rough mixes, this compactor of asphalt agglomerate Cat brings the amount of force necessary to get density without sacrificing consistency and productivity. Double drums in the rear and front part, the role of displacement of width, the optimum power and spraying water of high reliability system, provide incomparable performance in adverse conditions. The position of the operator provides total visibility, which is vital for a compactor operating in confined spaces and obstructions.

The Caterpillar CD54 comes equipped with double drums of drive and vibration on the front and rear, a width of displacement of 1.3 m for a width of 3 metres maximum compaction, optimum handling with touch sensitive direction control, total visibility of the perimeter and many other features that will provide customers a versatile machine for their tasks of compaction of asphalt. The new CD54 will allow Caterpillar dealers to continue competing in the growing category of 8 - 11.3 metric tons. Typical applications include highways, streets, regional roads, additions of lanes, industrial sites, coverings, runways and airports take-off and other works of paving of medium to high production.

The CD54 can be used in all phases of the compaction of asphalt, which reduces the need for several roller. It is extremely maneuverable and its large width of compaction to maximum displacement allows to cover layers with greater speed and lower probability of loss of heat prior to compaction.

Engine and water spraying system

The new CD54 is powered by an engine 3054C Cat turbocharged four-cylinder. The engine 3054C supplies 74.5 kW (101 HP) at 2200 rpm. This engine does not require reduction of power at altitudes of up to 3,000 meters and satisfies the requirements of the European Union relating to emissions from off-road engines, phase II.

Also, a single deposit of water, of 750 litres, provides operating hours. The design provides good visibility of the machine towards the rear drum. Water system controls are comfortably located in the front control panel. The button is located at the lever of propulsion and controls the operation of the spray bar. The system uses a single water tank located behind the post operation. Its slim and compact design offers a good visibility of front and rear, and both sides of the machine. Two folding steps located on the left side of the machine and the handrails provide accessibility during filling of water operations. A level indicator visible from inside the cabin, as well as from the ground, allows to monitor the level of water in the tank at all times. Double Cat water pumps are designed to be the most reliable and durable available. These pumps are equipped with full electric coating, connectors plugs and protection against the different weather conditions to avoid moisture and corrosion. A system of triple filter that provides an excellent filtering to minimize obstructions. The filters are easily accessible and can be removed quickly for cleaning without using special tools, which reduces downtime.

Double/double frequency amplitude

Double amplitude and frequency double system uses a unique breadth with each frequency. A switch in the management console matches automatically the amplitude and frequency to obtain complete control from the post of operation. The CD54 is easy to configure correctly, in such a way that the operator does not have to guess the functioning of the vibration.

Double drums

The double drums patented Caterpillar of the vibratory compactor of directional drum for asphalt agglomerate CD54 provide optimal maneuverability that does not sacrifice the finish of the layer. The interior of 2.8 m turning radius increases significantly the maneuverability of this compactor of asphalt performance agglomerate medium to high. An effective system of propulsion of double drums allows a turning radius of closed without damaging the warm layer.

Double drums of the CD54 drive system includes a divisor of electronic workflow that avoids unequal halves of the drum rotation and ensures a pair balanced at all times. To avoid tearing the material in the closed turns, the halves of the drums must rotate at different speeds. The drive system of double drums of the CD54, with bearings for preloaded tapered roller and maintenance free, also includes detection of engine speed that provides additional flow to the engine of the outer drum drive, which ensures a proportional speed between the halves of the drums.

Steering system

Coverage of three meters and maximum displacement means that it can cover thin layers faster and less likely to loss of heat prior to compaction. The touch control provides ease of management in the lever of propulsion to operate with one hand. An alarm alerts the operator when the drums are aligned, so the operator can concentrate on the conditions of the layer.

The CD54 provides three different steering modes: front, rear and coordination of front and rear. Coordinated management provides a turning radius of 2.8 meters for maximum maneuverability in the work.

Features and touch address. The advantages of the electronic address is combined with the feeling of power steering. The operator achieves a more realistic direction, extremely advantageous response to operate near vertical barriers and obstructions in the layer. The steering wheel friction increases when the drum encounters resistance, a unique feeling of the CD54.

Position of the operator

The ROPS/FOPS cab with full glass from floor to ceiling in the front and rear corners provides a line of sight without hindrance from the edges of the drums, the surfaces of drums and both sides of the machine. The right window of the cockpit can be opened easily to increase lateral visibility when necessary. Optimal visibility of the drums allows operators to provide the amount of water right to the surfaces of drums and also ensures optimum visibility when operating in displaced address mode. The seat with multiple positions provides several settings that help to keep the operator care and control. Multiple seat settings allow the operator to customize the weight, height, armrests, and support to suit your individual needs.

The CD54 comes equipped with the standard automatic control of speed (ASC) system, as well as a lever of ergonomic propulsion.

Electrical system

The electrical system uses a module (ECM) electronic control of the machine that allows a better control of the machine and greater ease of service. Electrical system of 12 volts with an 80 amp alternator is standard. The Cat 12 volt (1,000 amperes) and maintenance-free battery provides electrical current. The battery is located in the engine compartment. Electrical wiring responds to a code of numbers and colors, and high resistance of the battery cable connections are welded to increase reliability.

Ease of service

These machines are designed to provide a quick and simple service. All points of service daily and routine are accessible on the ground. Access to the filters and the points of service is done through tilt gates. Long service intervals reduce maintenance time and increase the availability of the machine.

  • Design of coupling without maintenance provides unparalleled reliability and the optional capability of biofuel offers an ecological alternative to standard fuel.
  • The patented double drum tapered roller bearings and articulation joints are sealed permanently, so that it does not require greased or service.
  • Modules (ECM) electronic control of the propulsion systems and vibration compatible with other Cat compactors, to expedite and facilitate the diagnosis.
  • Levels of coolant in the radiator and hydraulic oil, as well as the restriction of the engine air filter, can easily be checked through Visual indicators.
  • The machine is equipped with series with pressure test connections that allow to quickly diagnose all the hydraulic system.
