Komatsu introduces big wheel loader update at Quarry Days
Komatsu revealed two fully updated -11 wheel loaders in Arizona, the WA475-11 and WA485-11. Designed for aggregates and earthmoving operations, these machines are available in yard loader (YL) versions with a heavier counterweight, low-profile tires, and a larger bucket.
Kwanju Cho, product marketing manager for Komatsu North America, gave me a tour of the new wheel loaders. Highlights include:
1. Both models feature a new Komatsu engine and the Komatsu Hydrostatic-Mechanical Transmission (KHMT). Reducing fuel consumption while boosting power was a central goal in the development of both wheel loaders.
2. Komatsu has redeveloped the cab on these wheel loaders and the visibility is excellent. Two posts have been eliminated, which makes the cab feel even bigger and provides a confidence-boosting view to the rear of the machine that is further enhanced with a rear-object detection system. The new cab offers low-effort drive-by-wire Angle Feedback Joystick Steering and a heated and ventilated adjustable seat to keep operators comfortable and reduce fatigue. A steering wheel option is available.
3. Komatsu focused on improving the maintenance and safety features on both models, introducing extended service intervals for the engine oil and filter. New anchor point tie-offs make maintaining and cleaning the machines safer for operators.
