Want a versatile loader with the capacity to load highway trucks quickly?

Loading and moving materials in as few passes and cycles as possible not only helps increase productivity, but it also reduces costly wear and tear on machines. One versatile machine that offers that across multiple applications provides a distinct advantage.   

“The WA480-8 yard loader arrangement is designed to be a 3-pass match for loading aggregate and other processed materials into highway trucks,” said Adam Braun, Komatsu product marketing manager. “It is also adaptable for use in infrastructure, forestry and non-residential construction applications.”

A host of new features contribute to its high production in truck loading, carrying, stockpiling and hopper charging applications. Among them is a Komatsu designed, 7.2-cubic-yard bucket with curved side edges built to minimize spillage. Its internal space and shape provide smooth material flow, and the long bucket jaw and decreased strike plane angle results in easy fill and low resistance during pile penetration. Operators can easily see how much material is in the bucket with the integrated load meter system in the cab.

More than 1,400 pounds of added counterweight compared to a standard WA480-8 gives the yard loader arrangement the ability to handle increased bucket capacity and improves stability. Low-profile tires with increased ground contact and new heavy-duty front and rear axles provide additional stability. The front and rear frame have been redesigned on the yard loader arrangement with an increased diameter for a larger center hinge pin that connects the two.

Added productivity features include excellent visibility to the pile and surroundings, an easy-to-operate Advanced Joystick Steering System (AJSS), and a comfortable air-suspension seat.  Outside the cab, there are front frame steps, a folding left-hand mirror, tie off points and a front cab grab rail.

Komatsu’xs new WA480-8 yard loader arrangement is designed to be a 3-pass match for loading aggregate and other processed materials into highway trucks. It features a 7.2-cubic-yard bucket with curved side edges built to minimize spillage. A highly efficient air-cooled braking system helps maximize brake life in extended load-and-carry or high-speed applications.

Another highlight of the WA480-8 yard loader arrangement is the new highly efficient air-cooled braking system designed to maximize brake life in extended load-and-carry or high-speed applications. The dedicated system enhances higher cooling efficiency even in tough environments. In severe test conditions, the cooling system demonstrated a 56 to 58 degree Fahrenheit better cooling effect.  

“Stable cooling performance under high duty cycle operation reduces the risk of hydraulic oil overheating,” said Braun. “The electric drive pump has a sensor that senses the axle temperature and activates only when needed.”
