Mining Trucks 2011
The Komatsu SDA12V160 engine provides the highest horsepower in it’s class. With 1487 gross horsepower, this engine delivers faster acceleration and higher travel speeds with a high horsepower-to-ton ratio. High torque at low speed, impressive acceleration, and low fuel consumption ensure maximum productivity. Standard features of this engine include the Quantum electronic control system, Cummins Cense monitoring and pre-lubrication.
Komatsu’s seven-speed, electronically controlled, automatic powershift transmission uses a rubber damper to comfortably reduce harmful engine shock and vibration to the transmission. A lock-up system, consisting of a wet multiple-disc clutch, is actuated in F1-F7 gears for higher fuel savings. Electronic shift control with automatic clutch modulation in all gears and full diagnostics with memory. The transmission circuit uses a separate hydraulic circuit and cooler.
Komatsu torque converter is transmission-mounted and lock-up clutch is electronically controlled.
Item Function
Downshift inhibitor Even if the driver downshifts accidentally, a speed appropriate to the current gear is automatically set, limiting potential over-runs.
Over-run inhibitor When descending grades, if the vehicle’s speed surpasses the maximum for the current gear, the front and rear brakes
automatically operate, limiting potential over-runs.
Reverse inhibitor The vehicle is prevented from moving backward when operating the body.
Forward/Reverse shift inhibitor This device makes it impossible to shift from forward to reverse when the vehicle’s speed surpasses 4 km/hr 2.5mph.
Anti-hunting system When running near a shift point, smooth automatic shifting takes place.
Neutral safety The engine is prevented from starting when the shift lever is not in neutral.
