Loading and moving materials in as few passes and cycles as possible can help increase productivity, and reduce costly wear and tear on machines. Designed to be a three-pass match for loading aggregate and other processed materials onto highway trucks, the 299 horsepower (223kW) Komatsu WA480-8 yard loader can also be adapted for use in infrastructure, forestry, and non-residential construction applications.
Designed for increased productivity and versatility
The curved side edges of the Komatsu-designed, 7.2-cubic-yard bucket are built to minimize spillage, and the internal space and shape provide smooth material flow. The long bucket jaw and decreased strike plane angle help deliver easy to fill and low resistance during pile penetration. The integrated load meter system in the cab lets operators see how much material is in the bucket.
Additional productivity features on the WA480-8 yard loader include excellent visibility to the pile and surroundings, an easy-to-operate Advanced Joystick Steering System (AJSS), and a comfortable air-suspension seat.
For increased bucket capacity and stability, the yard loader arrangement has more than 1,400 pounds of added counterweight (compared to the standard WA480-8). Further stability is provided by low-profile tires with increased ground contact that is mounted to the new heavy-duty front and rear axles.
Collectively, the features on the WA480-8 yard loader enhance its versatility, making it suitable for truck loading, carrying, stockpiling, and hopper charging applications.
Maximized brake life
To promote maximized brake life in extended load-and-carry or high-speed applications, the WA480-8 yard loader has a new, highly efficient air-cooled braking system. The dedicated system enhances higher cooling efficiency even in tough environments. Stable cooling performance under high-duty cycle operation helps to reduce the risk of the oil overheating and in severe test conditions, this cooling system demonstrated a 56 to 58 degree Fahrenheit better-cooling effect. A sensor on the electric drive pump measures the axle temperature and activates only when needed.
