With newly designed front and rear frames and loader linkages, the Tier 4 Komatsu WA800-8
wheel loader has the most durable chassis in company’s model history, says Komatsu, based on
the design of the previous model. With an operating weight 254,700 pounds, the new wheel
loader is designed to load 60-100-ton haul trucks in quarry, aggregate, and mining applications.
The cab also has been re-engineered, says the company, featuring a 7-inch, high-resolution
monitor, heated/ventilated air-suspension seat, improved access, and enhanced visbility.
Komatsu’s KomVision with radar obstacle detection, is designed to provide the operator with a
“birds-eye” view of the working area on a dedicated monitor, and the system provides a visual
and audible alert when an object is detected.
Leveraging the power of connected technology, the WA800-8’s automatic dig, semi-automatic
approach, and semi-automatic dump systems can be used together or separately to automate the
work phases when “V-cycle” loading haul trucks. These systems were designed to help newer
loader operators become productive more quickly, says the company, as well as to reduce fatigue
for all operators.
The machine’s variable-traction control system and modulation-clutch system are aimed at
providing optimal tractive effort in various ground conditions. The WA800’s reinforced Z-bar
loader linkage provides high breakout force even in the most challenging digging applications,
says Komatsu. To reduce total cost of ownership, transmission and axle overhaul intervals on the
WA800-8 have been extended.
