The Komatsu 930E-5 rigid frame truck hauls up to 320 tons of payload and matches up with mining shovels in the 49-to-55-cubic-yard category. Powered by a Tier 4-Final Komatsu SSDA16V160-4 diesel that delivers 2,700 horsepower, the truck will consume up to 5 percent less fuel than its predecessor.
The DEF tank is designed to perform in freezing conditions, including a thaw capability to flow DEF within 70 minutes of starting the truck, using a thermostatically controlled engine coolant loop in DEF sump head and heated lines from the DEF tank to the SCR unit on the engine.
With on demand AC cooling for the control cabinet, wheels motors and grids, the Komatsu 930E-5 has decreased any parasitic loss and improved load carrying capacity, according to the company.
Tier 4 and Electrification
Komatsu uses High Pressure Common Rail fuel delivery to reduce particulate matter. Removal of NOx is accomplished by treating the exhaust through Selective Catalytic Reduction (SCR). The introduction of Diesel Exhaust Fluid (DEF) into the SCR canister generates a chemical reaction that breaks down the oxides of nitrogen into oxygen and nitrogen, both nonpollutants. Internal cleaning of the SCR is performed through an automatic process.
