Make every pass count
If you're looking to load, transport or move material, Komatsu yard loaders offer a great combination of productivity, fuel efficiency, operator comfort and ease of maintenance. A newly designed, bigger bucket and auto-digging system helps maximize bucket fill while minimizing operator fatigue. Tailor-made for loading in quarry environments that require a powerful engine and excellent stability, the WA500-8 yard loader has durable long life frames, axles and driveline components for efficient loading.
- Optimized bucket load for efficiently moving processed materials
- Enhanced operator comfort
- Increased productivity*
- Reduced fuel costs*
Note: *compared to the prior model
Features and benefits
High performance powertrain
Designed to help reduce fuel consumption, this loader features a large-capacity torque converter that combines with Komatsu's SmartLoader Logic engine control system to automatically create enough torque for each work phase and bolster productivity.
Trusted brake cooling system
Help get efficient performance and added confidence in load-and-carry situations with this vehicle’s front and rear brake cooling system.
Lower fuel consumption
Reduce idle time and save fuel with auto idle shutdown. Komatsu’s SmartLoader Logic acquires data from various sensors in the loader and controls engine torque based on job requirements.
Increased operator comfort
Get a more comfortable ride with a new standard, heated, air-suspension seat that provides enhanced support on rough roads. A large, quiet, pressurized cab provides excellent visibility.
Ease of access
Efficient maintenance with ease of access with large, gull-wing-type engine doors and large steps on each side of the frame and front of the cab.
Increase maneuverability
Designed to reduce operator fatigue, the Advanced Joystick Steering System (AJSS) allows wrist and finger control of steering and directional travel.
Move more material
Get increased power and control to help handle big bucket loads with this yard loader's large capacity bucket cylinder.
Optimized capacity
The large capacity bucket is optimized based on material density, with up to 9.8 yd3 capacity.
Stay stable with increased ground contact
875/65 tires increase ground contact area to help improve stability. The low profile also reduces sidewall flex to provide more balance while dumping into trucks or hoppers.
