With newly designed front and rear frame and loader linkages, the Tier 4 Komatsu WA800-8 wheel loader has the most durable chassis in model history. Showed at the Komatsu Booth N-10825 at Conexpo-con/agg 2020, the 254,700 lb. (115,530 kg) wheel loader is designed to load 60-100 ton haul trucks in a quarry, aggregate, and mining applications.
To keep operators comfortable throughout long shifts, the cab has been re-engineered with a 7-inch high-resolution monitor, a heated and ventilated air-suspension operator seat, improved access, and enhanced visibility. KomVision with radar obstacle detection provides the operator with a birds-eye view of the working area on a dedicated monitor. Radar obstacle detection 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 as well as reduce fatigue for all operators.
The machine’s variable traction control system and modulation clutch system provide 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.
To reduce the total cost of ownership, transmission and axle overhaul intervals on the WA800-8 have been extended.
