With newly designed front and rear frames and loader linkages, the Tier 4 WA800-8 Komatsu 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 wheel loader 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 wheel loader’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.
