It works on three levels: Passive: manages actual work condition information, provides an on-board operation manual, and reports machine history. Active: provides the error code and acts as a warning system, reducing expensive machine breakdowns. Measuring tool: The service technicians can see the various machine parameters, without a need for special, expensive hardware and software. Also makes technical information immediately available, optimising operation time. Human-machine interface Palm command electronic controlled travel joystick The palm command travel joystick provides the operator with an environment that supports a comfortable posture and precise machine control without fatigue. Shifting gears is easily carried out with gear shift lever push button control. The system s proportional steering controller increases safety and assists in precision operations. At the lowest speeds, the total range of steering directions is fully available, giving precise direction control. This makes counter-rotation turns possible when standing still. The range of steering directions is proportionately reduced as the dozer s travel speed increases. This keeps turning manoeuvres within safe ranges, making sharp, unsafe turns at high speeds impossible. All of the signals are transmitted via an engine and transmission controller, preventing overload of the hydraulic steering system and protecting hydraulic and mechanical parts.because the controller linkages between the engine speed dial, decelerator pedal, and the engine are electrical, there is no wear of moving linkage parts. Auto shift down switch Decelaration pedal controller Service Switch Monitor panel Fuel control dial Trans mission contr oller Travel control lever Outline of Electronic Control System Acceleration sensor Brake pedal potentiometer speed control dial The rate of engine RPMs is continuously controlled and checked by the engine controller.

80561_D65_Engels 12-06-2003 09:42 Pagina 6-15 C RAWLER PRODUCTIVITY FEATURES POWER TRAIN ELECTRONIC CONTROL Clutch pressure Electronically Controlled Modulation Valve (ECMV) Conventional modulation valve Time ECMV (Electronic Controlled Modulation Valve) controlled transmission Using an innovative series of valves, the transmission controller automatically makes each clutch engagement in a smooth way. The speed of each shift is based on travel conditions such as gear speed, engine revolution and current shifting sequence. This provides smooth, shock-free clutch engagement, longer component life, and increased ride comfort. It also assists productivity because the ECMV manages the transmission, allowing the operator to concentrate on managing the blade position. Steering planetary gear units Hydraulic motor Brakes Hydrostatic Steering System smooth, powerful turning The Hydrostatic Steering System (HSS) is powered by an independent hydraulic pump with engine power transmitted to both tracks without power interruption on the inside track. When the machine turns, the outside track moves faster and the inside slower, for smooth, powerful turns. Counter-rotation is available for minimum turning radius providing excellent manoeuvrability. Shock-free steering reduces machine vibration and minimizes operator fatigue. The hydrostatic steering system reduces track damage to the ground to a minimum. Preset travel speed function Preset travel speed selection function is provided as standard equipment. The preset switch enables the operator to select fore and aft travel speed among three preset patterns: F1 F2, F2 R2 and manual shift. When the F1 R2 or F2 R2 preset pattern is selected, and the travel control PCCS moves from forward to reverse direction, the machine travels forward/reverse with F1/R2 or F2/R2 speed automatically. This function reduces gear shifting time during repeated round trip operations. UP MANUAL MODE (F1-R1) Press DOWN switch Press DOWN switch F1-R2 MODE Press UP switch Press UP switch Heavy load Light load Blade control joystick (PPC) The blade control joystick uses a PPC (Proportional Pressure Control) valve. The design of the blade control joystick is the same as the travel control joystick. The PPC control, combined with the highly reliable Komatsu hydraulic system, enables superbly fine blade control. It keeps the blade movement independent from the blade load and speed of the machine. The PPC delivers a proportional response to the joystick, giving the operator essential sensory feedback of what the blade is experiencing, and improving the precision of the work that is being done. The work equipment and HSS system use the same variable piston pump that delivers force and flow only when needed. This saves on fuel and delivers maximum engine power to the tracks, therefore increasing performance. DOWN F2-R2 MODE Actuated on heavy load or steep slopes Auto-downshift function The engine controller monitors engine speed, travel gear and travel speed. When a load is applied and the machine travel speed is reduced, the controller automatically downshifts and optimises the gear speed to provide high fuel efficiency. Electric outlets that match today s technologies Good communications help ensure top productivity. To keep the driver in contact with the site management, the dozer s 60W power supply provides a 12V service for radio, walkie-talkie and mobile phone use. This function provides comfortable operation and high productivity without manual downshifting. (This function can be deactivated by a cancel switch.) 6 7

80561_D65_Engels 12-06-2003 09:42 Pagina 10-15 C RAWLER UNDERCARRIAGE WORK ENVIRONMENT Low drive undercarriage Komatsu s design is extraordinarily tough and offers excellent grading ability and stability. Newly designed large-diameter bushings, substantial track link height, and superior oil seals help to increase undercarriage durability. Serviceability is also assisted by the remote greasing of the equaliser bar centre pin. And the segmented sprockets can be replaced individually, by hand, making it possible for one mechanic to carry out replacements at the job site. The design also gives the driver a perfect view of the blade tips, making work easier and more precise. The Komatsu undercarriage design provides stable operations with very low vibration levels. The reasons for this are: Two upper carrier rollers prevent the link assembly from jumping up and down. The track rollers are double flanged, thus supporting the link assembly in the best way and reducing wear to a minimum. Operator comfort Operator comfort is essential for safe and productive work. The provides a quiet, comfortable environment where the operator can concentrate on the work at hand. Comfortable ride with new cab damper mounting s cab mounts use a newly designed cab damper that provides an excellent shock and vibration absorbtion capacity with its long stroke. Cab damper mounts soften shocks and vibrations while traveling over adverse conditions, which conventional mounting systems are unable to absorb. The cab damper spring isolates the cab from the machine body, suppressing vibrations and providing a quiet, comfortable operating environment. Cab damper Mounting Rubber Boot Hexagonal pressurised SpaceCab TM The cab s new hexagonal design and large tinted glass windows provide excellent front, side, and rear visibility. Air filters and a higher internal air pressure combine to prevent dust from entering the cab. Silicon oil Spring Komatsu offers 3 different under carriages to meet all request of application: - EX: for rocky area. EXL: where underground is more even and lower groundpressure with increased stability gives an advantage. - PX: for low ground pressure applications. New suspension seat uses a newly designed heavy duty suspension seat. Fore and aft sliding rails and suspension spring have been newly designed to increase strength and rigidity. The new seat provides excellent support, improving riding comfort. Fore and aft seat movement has been designed for all sizes of operators. 10 11
