D85EX/PX-15 C RAWLER DOZER Comfortable Ergonomic SpaceCab Komatsu s new cabin meets the needs operators who work long shifts PCCS (Palm Command Control System) Komatsu s new PCCS ergonomically designed control system delivers a work environment with complete operator control. 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. Auto shift down switch Service Switch Monitor panel Fuel dial 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. The hydrostatic steering motor, with a capacity of 186 kw, is the most powerful in its class. 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. Decelaration pedal Engine controller Trans contr Water temp. Fuel control valve unit Engine Engine oil pressure Engine speed Fuel temp. Left-hand Joystick Blade and Ripper Control Joystick Power Train Electronic Control System 4 Smooth and soft operation controlled by the engine and transmission controller D85X/PX-15 utilises a newly designed power train electronic control system. The controller registers the amount of operator control (movement of lever and operation of switches) along with machine condition signals from each sensor, to calculate accurately the control of the transmission for optimal machine operation. The ease of operation and productivity of the new D85EX/PX is greatly improved through these new features.
D85EX/PX Engine controller POWER TRAIN ELECTRONIC CONTROL By controlling the fuel injection system, the engine controller optimises fuel consumption. 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. control Travel control lever Outline of Electronic Control System Engine speed control dial The rate of engine RPMs is continuously controlled and checked by the engine controller. This controls the engine fuel injection when needed, saving on fuel. Because the controller linkages between the engine speed dial, decelerator pedal, and the engine are electrical, there is no wear of moving linkage parts. mission oller Acceleration sensor Brake pedal potentiometer Transmission control valve ECMV ECMV ECMV ECMV Transmission output speed sensor Electronic controlled Transmission When Turned 15 Fully-adjustable suspension seat and travel control console. The driver s seat and console are among the most important parts of the driver s equipment. The comfortable, heavy duty, ergonomic seat, complete with headrest, gives the driver a secure and comfortable work environment. For reverse operations, the operator can turn the seat 15 to the right and fix it in that position, significantly improving rear visibility and reducing neck strain. The travel control joystick, with its complete console, can be moved forwards, backwards, and in height so that its fitted to each operator. 5
D85EX/PX-15 C RAWLER DOZER PRODUCTIVITY FEATURES 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. 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 DOWN F2-R2 MODE Press DOWN switch Press UP switch F1-R2 MODE Press DOWN switch Press UP switch F1-R1 MODE Heavy load Light load 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. This function provides comfortable operation and high productivity without manual downshifting. (This function can be deactivated by a cancel switch.) 6
D85EX/PX POWER TRAIN ELECTRONIC CONTROL Steering planetary gear units Hydraulic motor Hydrostatic Steering System smooth, powerful turning The Hydrostatic Steering System (HSS) is powered by an variable 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. Brakes 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. 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. 7
D85EX/PX-15 C RAWLER DOZER PRODUCTIVITY FEATURES Engine The Komatsu SA6D125E-3 engine delivers 179 kw 240 HP at 1.900 rpm. This fuel-efficient common rail engine, together with the heavy machine weight, make the D85EX/PX superior crawler dozers in both ripping and dozing operations. The engine is designed to surpass European Stage II regulations, and features direct fuel injection, turbocharger, and aftercooler to maximise fuel efficiency.to minimise noise and vibration, the engine is mounted to the main frame with rubber cushions. Hydrostatic driven engine cooling fan Fan rotation is automatically controlled depending on coolant and hydraulic oil temperature, saving fuel and providing great productivity with a quiet operating environment. Easy cleaning with hydraulic driven radiator fan The radiator core and the core on the front side of the oil cooler can be easily cleaned by running the hydraulic engine cooling fan in reverse. Accordingly, the cleaning intervals of those cores can be increased resulting in better cooling efficiency. 8

High-tensile-strength steel has been incorporated into the front and sides of the blade for increased durability. Ripper (EX) The multi-shank ripper features a long sprocket centre-to-ripper point distance, making ripping operations easy and effective while maintaining high penetration force. The multi-shank ripper is a parallelogram design ideal for ripping in tough material. 9
D85EX/PX-15 C RAWLER UNDERCARRIAGE DOZER 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: The long track design 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. 10
D85EX/PX WORK ENVIRONMENT Operator comfort Operator comfort is essential for safe and productive work. The D85EX/PX provides a quiet, comfortable environment where the operator can concentrate on the work at hand. Comfortable ride with new cab damper mounting D85EX/PX 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 New suspension seat D85EX/PX 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. 11
D85EX/PX-15 C RAWLER DOZER EASY MAINTENANCE Preventative maintenance Preventative maintenance is the only way to ensure long service life from equipment. That s why Komatsu designed the D85EX/PX with conveniently located maintenance points to make necessary inspections and maintenance quick and easy. Centralised service station To assure convenient maintenance, the transmission and HSS oil filters, power train oil level gauges and hydraulic tank are arranged in the right side of the machine. Modular power train design Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage. Engine Power train unit Hull frame Final drive Pivot shaft Track frame Monitor with self-diagnostic function With the starting switch turned ON, the monitor displays on the panel, check-before-starting and caution items appear on the right lower part of the panel.
