The hydrostatic drive WA320PZ-6 features Komatsu’s PZ parallel-lift arm system with bucket capacities from 2.3-3.2 cu m, along with hydrostatic drive, for maximum versatility and productivity across loading, handling and lifting applications. As with all our wheel loaders, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

Electronically-controlled HST
The electronically-controlled HST consists of a 1-pump, 2-motor system. This system allows for high-efficiency and high tractive effort. The HST provides quick travel response and aggressive drive into the pile. The variable displacement system automatically adjusts to the tractive effort demand to provide maximum power and efficiency
