[. . . ] Under deceleration, the HST system acts as a dynamic brake on the mechanical drive system. The dynamic brake can hold the loader in position on most workable slopes. As the machine moves and gains ground speed, the torque demand decreases and the low speed motor is effectively removed from the drive system by a clutch. At this point, the flow is going to the high-speed motor and the low-speed motor is not causing a drag on the system. [. . . ] when the F/R lever is operated. Tractive effort 0 Travel speed Net: 125 kW 167 HP Low Emission Engine This engine is EPA Tier 3 emission regulations and EU Stage 3A emission regulations certified, without sacrificing power or machine productivity. Low Fuel Consumption The high-torque engine and Hydrostatic Transmission (HST) with maximum efficiency in the low-speed range provide low fuel consumption. Tractive effort 0 4 13 Travel speed (km/h) Variable Traction Control System The tractive effort of the machine, when traveling at a low speed, can be reduced by using the traction control switch. Combined with the function of torque proportioning differentials, this system exerts the following effects. Max: Traction control switch is OFF. tractive effort can be adjusted in 3 stages when the traction control switch is ON. Eco Indicator The eco indicator will help an operator to promote energy saving. Tractive effort Accelerator Pedal Sensitive HST Control Finely-tuned HST control according to the accelerator pedal angle reduces shocks and allows smoother traveling and better energy-saving operation. Eco indicator 0 Travel speed Facilitates operation on soft ground where the tires of the machine are apt to slip. Eliminates excessive bucket penetration and reduces tire slippage during stockpile loading to improve the work efficiency. Furthermore, the maximum tractive effort can be adjusted in three stages (one stage for conventional machines) when the traction control switch is ON. This allows the operator to select the optimum tractive effort for diversified road conditions. Maximum Dumping Clearance and Reach The long lift arms provide high dumping clearances and maximum dumping reach. The operator can even level loads on the body of a dump truck easily and efficiently. Dumping Clearance: 2800 mm 9'2" Dumping Reach: 1130 mm 3'8" (2. 7 m3 3. 5 yd3 bucket with B. O.

Komatsu loaders are manufactured with an integrated production system under a strict quality control system. Front axle Transfer case Rear axle Engine EASY MAINTENANCE WA320PZ-6 WA380-6 High-rigidity Frames and Loader Linkage The front and rear frames and the loader linkage have got more torsional rigidity to provide resistance increased to stresses. Frame and loader linkage are designed to accommodate actual working loads, and simulated computer testing proves its strength. Wet multi-disc brakes and fully hydraulic braking system mean lower maintenance costs and higher reliability. Brakes require no adjustments for wear, meaning even lower maintenance. The parking brake is also an adjustment-free, wet multi-disc for high reliability and long life. Added reliability is designed into the braking system by the use of two independent hydraulic circuits, providing hydraulic backup should one of the circuits fail. Fully hydraulic brakes mean no air system to bleed, and no condensation of water in the system that can lead to contamination, corrosion, and freezing. nipple Photo may include optional equipment. Flat Face-to-Face O-Ring Seals Flat face-to-face O-ring seals are used to securely seal hydraulic hose connections. hose O-ring EMMS (Equipment Management Monitoring System) Monitor is mounted in front of the operator for easy view, allowing the operator to easily check gauges and warning lights. A specially designed two-spoke steering wheel allows the operator to easily see the instrument panel. Maintenance Control and Troubleshooting Functions Action code display function: If an abnormality occurs, the monitor displays action details on the character display at the center bottom of the monitor. Monitor function: Controller monitors engine oil pressure, coolant temperature, air cleaner clogging, etc. If the controller finds abnormalities, the error is displayed on the LCD. Replacement time notice function: Monitor informs replacement time of oil and filters on the LCD when replacement intervals are reached. The low-noise engine, hydraulically driven fan, and hydraulic pumps are mounted with rubber cushions, and the cab sealing is improved to provide a quiet, low-vibration, pressurized, and comfortable operating environment. Pillar-less Large Cab A wide pillar-less flat glass provides excellent front visibility. [. . . ] .
