Komatsu’s new WA380-8 wheel loader has a 6.69 liter, 191 HP Komatsu SAA6D107E-3, variable geometry turbo charged and after cooled Tier 4 Final certified engine which uses up to six per cent less fuel than its Tier 4 Interim predecessor. SmartLoader Logic software combines with a lockup torque converter, which activates in second, third and fourth gears to provide optimal engine torque for improved acceleration, hill climbing, a higher top speed and fuel savings. The Komatsu Diesel Particulate Filter (KDPF) and other after treatment components work in harmony with the engine for efficiency and long life. A Selective Catalyst Reduction (SCR) assembly is incorporated to reduce NOx emissions using diesel exhaust fluid (DEF). The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters and after treatment functions to optimize performance, reduce emissions and provide advanced diagnostic capability. The cab has also been upgraded. A new, air-suspension, high-back, heated seat that softens machine vibrations for operator comfort, and cast frame members for increased strength. Seat-mounted electronic pilot control levers with F-N-R switch for operator comfort and convenience. Telematics system provides key machine metrics, including KDPF status, DEF-level data, fuel consumption, plus performance information collected and sorted by operator ID. Auto Idle Shutdown function reduces idle time and saves fuel. Auxiliary jack and two 12 volt ports. A seven inch, full color, high-resolution monitor with ecology guidance supports efficient machine operation. A dedicated, full color, seven-inch, rear-view monitor is standard. Outside the cab has also been modified. Swing out cooling fan with wider fin spacing and standard auto-reversing fan for ease of cleaning. Gull-wing engine doors that provide quick, convenient access for daily checks and service items. Full-rear fenders are standard. Additional hinged panels at each side of the machine for easy access to regeneration components. www.komatsuamerica.com
