User manual KOMATSU WA320PZ-6 BROCHURE

[. . . ] This combination makes the loader very aggressive and quick. 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. This can be an advantage in stockpiling and ramp loading. [. . . ] 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. Contaminants are kept out, reducing wear and resulting maintenance. 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. The wiper arm covers a large area to provide great visibility even on rainy days. The large cab area provides maximum space for the operator. 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. The adjustable wrist rest provides the operator with a variety of comfortable operating positions. Right-side control panel The operator can select the speed range, maximum travel speed in 1st, tractive effort. 4 6 1 5 7 2 1:Speed range selector switch 2:Variable shift switch 3:Traction control switch 4:Max. traction switch 5:Fan reverse switch 6:Quick coupler lock switch 7:2 mode bucket leveler switch 3 Photo may include optional equipment. 8 9 WA320PZ-6 W HEEL L OADER WITH P ARALLEL Z BAR L INKAGE WHEEL LOADER WITH PARALLEL Z BAR LINKAGE SPECIFICATIONS ENGINE Model . .
