The WA500-8 Yard Loader adds to the proven design and technology of the WA500-8 to help move even more material faster, move more trucks out of the yard, and move your business forward. The WA500-8 Yard Loader is configured with a large capacity bucket that is optimized based on material density with up to 9.8 yd³ capacity, additionally a large capacity bucket cylinder provides increased power and control to help handle those big loads. Added stability comes from 875/65 tires that increase ground contact and feature a low profile sidewall that reduces flex for added stability while dumping into trucks or hoppers. An additional counterweight also adds to the improved stability and allows the increased capacity of the bucket, while the front and rear brake cooling system helps to control brake temperatures in higher speed applications to ensure optimum performance in load and carry situations.

PROVEN DESIGN AND TECHNOLOGY

• Large capacity bucket is optimized based on material density, with up to 9.8 yd3 capacity. This helps increase productivity in applications such as truck loading, carrying, stock piling and charging hoppers.
• Large capacity bucket cylinder provides increased power and control to help handle big loads.
• 875/65 Tires increase ground contact area for improved stability. The low profile also reduces sidewall flex for more stability while dumping into trucks or hoppers.
• Joystick Steering (Optional) helps to reduce operator fatigue in repetitive V-Cycle loading.
• Additional Counterweight helps improve stability, and allows for increased bucket capacity while the contoured shape maximizes ground clearance for stock piling applications.
• Brake Cooling System (Front & Rear) helps control brake temperatures in higher speed applications to ensure optimum performance in load & carry situations.

DUAL-MODE ENGINE POWER SELECT SYSTEM

This wheel loader offers two selectable operating modes — Power (P) and Economy (E).

• P Mode: This mode provides maximum power output for hard- digging operation or hill climbing.
• E Mode: This mode provides maximum fuel efficiency for general loading.

AUTOMATIC DIGGING SYSTEM

The new automatic digging system actuates the bucket tilt and lifting operations by sensing the pressure applied to the work equipment. This system can alleviate operator's fatigue and optimize bucket load. This system is activated through the LCD color monitor panel.

NEW OPERATOR SEAT WITH ELECTRONIC PILOT CONTROL (EPC) LEVERS

A new standard, heated, air-suspension seat provides enhanced support on rough roads and dampens machine vibrations, providing a more comfortable ride for the operator. An EPC-lever console is built into, and moves with, the seat. The angle of the armrest is fully adjustable for optimum operator comfort. A secondary F-N-R switch is incorporated in to work equipment lever configurations.

OPERATOR IDENTIFICATION FUNCTION

An operator identification (ID) code can be set for each operator, and used to manage operation information of individual machines through KOMTRAX. Data sent from KOMTRAX can be used to analyze operation status by operator job, as well as by machine.

KOMATSU SMARTLOADER LOGIC

The WA500-8 features Komatsu SmartLoader Logic, which controls engine torque to match machine demands. For example, engine torque needs are higher for digging in V-shape loading, but lower when driving with an empty bucket. This system optimizes the engine torque for all applications to minimize fuel consumption. Komatsu SmartLoader Logic functions automatically and doesn’t interfere with operation, saving fuel without decreasing production.

LARGE-CAPACITY TORQUE CONVERTER

The Komatsu-designed power train features a large capacity torque converter for optimum efficiency. The WA500-8 has improved efficiency in V-shape loading applications because the increased tractive effort does not require full throttle. The large capacity torque converter allows the loader to up-shift gears faster for improved acceleration and hill climbing ability. The WA500-8 achieves high gear ranges and maintains high travel speed when working in load-and-carry applications. In most applications, production is increased and fuel consumption is reduced, resulting in improved fuel efficiency.

STANDARD REAR VIEW MONITORING SYSTEM

The dedicated, full-color monitor on the right side of the cab provides the operator with a rear view of the machine. This monitor can be always on or only on when the loader shifts into reverse. Guidelines provide the operator with visual cues for the width of the loader.

REMOTE BUCKET AND BOOM POSITIONER

The operator can set the bucket angle and remote boom positioner from the cab. Both upper and lower boom limits are adjustable in the cab with the push of a button. The bucket positioner can store three horizontal settings, allowing the operator to easily change attachments without resetting the bucket level position.

KOMATSU INTEGRATED LOAD METER SYSTEM

The integrated load meter system displays information directly to the machine’s main monitor display and information is also available remotely via KOMTRAX. Load sub total and cancel functions are performed with buttons integrated to the machine work levers.

SWING-OUT TYPE COOLING FAN AND WIDER CORE RADIATOR

The cooling fan swings out for easier cleaning. The coolers feature wider-spaced cooling fins to reduce clogging.
