WA150-5 Wheel Loaders

With bucket capacities from 1.3-1.7 cu m, our hydrostatic drive WA150-5 loader is capable of loading and handling many different types of material, across a wide range of industry sectors. 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.

High Productivity and Low Fuel Consumption

A powerful SAA4D102E-2 turbocharged air-to-air aftercooled diesel engine provides a new output of 71 kW / 96 HP for the WA150-5. The fuel consumption is reduced up to 10% due to the high torque engine and Hydrostatic Transmission (HST) with maximum efficiency in the low-speed range

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

High-Rigidity Frames

The front and rear frames along with the loader linkage have high rigidity to withstand repeated twisting and bending loads to the loader body and linkage. The structure is similar to those of large sized wheel loaders and the reinforced loader linkage ensure high strength.
