Wheel Loaders WA470-7
Features
The WA470-7 scores high marks for economy and power at the same time. Komatsu’s Tier 4 interim technology ensures that the engine runs efficiently and saves fuel over the previous model. Selectable economy or power engine modes and SmartLoader Logic make sure the WA470-7 can be operated in the most efficient way. A large capacity torque converter with lock-up gives the WA470-7 tremendous power in the pile for filling the bucket and speed to climb ramps.
