Power Train ­ Engine The Cat® C27 engine with ACERTTM Technology delivers the power and reliability necessary to perform in the most demanding underground mining applications. Designed for efficient operation, excellent fuel efficiency, lower emissions, reduced engine noise and lower operating costs. 4 Power Train ­ Transmission The Cat seven-speed planetary power shift transmission and mechanical power train is matched with the electronic unit injection C27 engine with ACERTTM technology to provide consistent power and efficiency for peak power train performance. 5 Engine/Power Train Integration The Cat Data Link electronically combines engine, transmission, brake and operational information to optimize overall truck performance. [. . . ] Cat oil-cooled disc brakes are designed with large discs and plates for reliable, adjustment-free operation and performance. Brakes are completely enclosed and sealed to prevent contamination and reduce maintenance. An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Electronically controls retarding on grade to maintain optimum engine rpm and oil cooling. Additional braking may be applied using the manual retarder or the brake pedal. ARC allows the operator to maintain optimum engine speeds for faster downhill hauls and greater productivity. Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. 2 1 1 2 3 4 5 6 7 Parking/Secondary Piston Service/Retarding Piston Friction Discs Steel Plates Actuating Springs Cooling Oil In Cooling Oil Out 3 7 4 5 6 Ease of Operation. ARC increases operating ease, resulting in greater operator confidence with less fatigue. Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Fuel Efficiency. The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM reduces fuel injection to minimum value or exceptional fuel economy. 7 Operator's Station Ergonomically designed for operator comfort, superior control and high productivity. Ergonomic Layout. The AD55B operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. All controls, levers switches and gauges are positioned to maximize productivity and minimize operator fatigue. Integral to the cab and frame, both the Rollover Protective Structure (ROPS) and Falling Objects Protective Structure (FOPS) are resiliently mounted to the mainframe to isolate the operator from vibration for a more comfortable ride. Optional soundsuppressed ROPS cab provides a quiet, secure working environment. Enclosed design provides fresh, pressurized, temperature-controlled air circulation with air-conditioned comfort and a more comfortable working environment. Suspension Seat. Ergonomically designed, fully adjustable suspension seat with adjustable armrests provide optimal operator comfort. Thick cushions reduce pressure on lower back and thighs. Wide, retractable seat belts provide a secure, comfortable restraint. Comfort wheel with tilt steering provides a comfortable driving position, secure grip and greater control. Caterpillar Electronic Monitoring System (CEMS) continuously provides critical machine data to keep the machine performing at top production levels. [. . . ] When Cat products reach the field, they are supported by a worldwide network of parts distribution facilities, dealer service centers, and technical training facilities to keep your equipment up and running.
