Komatsu’s first wheel loader with Tier 3 engine

Komatsu America Corp. of Vernon Hills, Ill., has introduced the company’s first wheel loader equipped with a Tier-3-compliant engine. The 118,385-lb WA600-6, designed for smaller mining applications, offers improved productivity, lower fuel consumption and increased reliability over the WA600-3.

The wheel loader is powered by a Komatsu Tier 3, SAA6D170E-5 six-cylinder engine, producing 502 HP at 1,800 RPM, a significant increase in horsepower over the previous model. The engine is equipped with innovative new technologies including an electronic control system to optimize vehicle performance, a heavy-duty high pressure common rail fuel injection system, a new combustion system for reduced noise and fuel consumption, a cooled exhaust gas recirculation system, and an air-to-air charge air-cooling system. It comes standard with dual-mode engine power: an Economy mode for fuel efficiency, and a Power mode for maximum productivity.

Inside its large cab is standard automatic joystick steering for easier and more accurate control. Operator fatigue is reduced with rubber and silicone viscous damping mounts that reduce cab vibration and noise levels.

Through its distributor network, Komatsu offers a state-of-the-art parts and service program to support the equipment. Visit www.komatsuamerica.com for more information.
