Komatsu's new 128-ton wheel loader is built for serious loading efficiency

Komatsu America Corp. has introduced the WA900-8. The 256,618-pound (116,400 kg) wheel loader is equipped with an EPA Tier 4 Final certified emission regulations-compliant engine, and is purpose-built to load 70–150 ton haul trucks.

"The WA900-8 is the perfect machine for loading haul trucks in limestone pits because the all new Komatsu bucket design, with modified profile, maximizes bucket fill to increase productivity," said Robert Hussey, product marketing manager, Komatsu America Corp.  "The large pillarless cab offers great visibility, and the higher capacity air suspension seat along with the Electronically Controlled Suspension System (ECSS), provides a smooth ride for better travel performance to keep operators comfortable throughout long shifts." 

Productivity & efficiency

• Variable Traction Control System and Modulation Clutch System provide optimal tractive effort for various ground conditions
• Komatsu SmartLoader Logic helps reduce fuel consumption while maintaining production levels 
• Closed Center Load Sensing Hydraulic System delivers hydraulic flow based on application demand, saving fuel and reducing hydraulic oil temperatures
• Throttle lock with auto-deceleration improves cycle times by maintaining high work-equipment performance

Under the hood

• U.S. EPA Tier 4 Final emission regulation-compliant engine SSA12V140E-7 outputs a net horsepower of 899hp (up 5 percent from 856 hp on the WA900-3E0)
• Dual Komatsu Diesel Particulate Filters (KDPF) / No Selective Catalytic Reduction (SCR) system and no DEF required
• Variable Geometry Turbochargers (VGT) ensure precise engine control and quick response

Accessibility & operator comfort

• Advanced Joystick Steering System (AJSS) and Electronic Pilot Control (EPC) work equipment control levers provide quick and precise response to operator input
• Automatic dig system, semi-automatic approach and dump system help less experienced operators become more productive and can reduce fatigue for experienced operators
• High resolution, 7-inch monitor with dedicated rearview camera
• 45-degree stairways on the left- and right-hand side of the machine and walkways in front of the cab and on the rear counterweight provide easy access on the machine

New machine technology

• Advanced machine monitoring system, with onboard diagnostics viewable with the 7-inch LCD monitor, no laptop required for machine troubleshooting
• KomVision with radar obstacle detection, a six-camera system on a dedicated LCD monitor provides a bird's-eye view around the machine and an audible alert when an obstacle is detected in the working area for improved operator situational awareness (optional)
• Enhanced KOMTRAX Plus, for immediate remote diagnostics of machine heath and performance with operator ID and integration with 3rd party telematics systems
• Energy savings operation ECO guidance provides operator with real-time recommendations to improve machine operation efficiency

Reliability & durability

• Completely redesigned front and rear frame and loader linkages make it the most durable chassis in model history
• New standard brake cooling system reduces brake oil temperature, resulting in longer brake-service life
• Engine pre-lubrication system raises engine oil pressure before startup to ensure full lubrication of all engine components
