User manual KOMATSU WA320-6 BROCHURE

[. . . ] 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. An inching pedal gives the operator excellent simultaneous control of his travel and equipment hydraulic speeds. By depressing the inching pedal, drive pump flow to the motors will decrease, reducing ground speed and allowing the operator to use his accelerator to increase flow to his equipment hydraulics. Depressing the inching pedal further will activate the service brakes. Transfer case WA320-6 WA380-6 Electronically-Controlled HST with Variable Shift Control System The operator can choose between first, second, third or fourth maximum speeds by dialing the speed range selector switch. [. . . ] 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 0 Travel speed 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 Engine Piston Pump Low speed piston motor 0 Travel speed To differentials High speed piston motor 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: 2850 mm 9'4" Dumping Reach: 1035 mm 3'5" (2. 8 m3 3. 7 yd3 bucket with B. O. C. ) 5 4 WA320-6 W HEEL L OADER WHEEL LOADER INCREASED RELIABILITY Komatsu Components Komatsu manufactures the engine, transfer case and hydraulic components on this wheel loader. Komatsu loaders are manufactured with an integrated production system under a strict quality control system. Front axle Transfer case Rear axle Engine EASY MAINTENANCE WA320-6 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. Gull-wing Type Engine Side Doors Open Wide The operator can open and close each gull-wing type engine side door easily with the assistance of a gas spring to perform daily service checks from the ground. Cathion Electrodeposition Primer Paint/ Powder Coating Final Paint Cathion electrodeposition paint is applied as a primer paint and powder coating is applied as topcoat to the exterior metal sheet parts. Some external parts are made of plastic providing long life and high impact resistance. 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. 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. The wiper arm covers a large area to provide great visibility even on rainy days. The front mounted air conditioner was introduced to increase seat reclining and backward slide adjustment. Rear-hinged Full Open Cab Doors Entry and exit into the new komatsu cab starts with sloped staircase type steps and large diameter handrails for added comfort. The large cab doors are rear-hinged to open fully offering easy entry/exit and will not hamper visibility when operating the machine with the doors latched open. Easy-to-operate Loader Control Mono-lever A new mono-lever using PPC (Proportional Pressure Control) allows the operator to easily operate the work equipment, to reduce operator fatigue and to increase controllability.
