Komatsu America Corp. introduced the WA900-8, a wheel loader equipped with an EPA Tier 4 Final-engine and purpose-built to load 70- to 150-ton haul trucks. It is perfect for limestone pits, the company reported.

The large pillarless cab offers great visibility, and the higher-capacity air suspension seat along with the electronically controlled suspension system provides a smooth ride, the company reported. Features include a variable traction control system and modulation clutch system, Komatsu SmartLoader Logic, the company’s Closed Center Load Sensing Hydraulic System, and throttle lock with auto-deceleration. It also comes with an advanced machine-monitoring system, radar obstacle detection and ECO guidance.

Separately, Komatsu released the 354-horsepower D155AX-8 LGP (low-ground-pressure) dozer. It offers two blade options, more track on the ground, and 47% lower ground pressure than the standard model. The ground contact area is increased by 72% over the standard model for improved flotation in soft ground, the company reported. The long and wide undercarriage provides better stability on slopes and excellent machine balance.
