In March 2004, Komatsu, one of the greatest Construction and Mining Heavy Equipment manufacturers, introduce two new Wheel Loaders: The WA150-5 and WA200-5 models. The main feature of these new wheel loaders is their exceptional electronic transmission system: The HST or Hydrostatic Transmission.

The great sensitivity of the HST system let Komatsu Wheel Loader provide the exact energy amount required on current operation for optimal power and greater precision. Several control switch's help wheel loader operator to set maximum speed on hydraulic operation to provide the most productive answer related to the current labour conditions.

The traction control system of the new Komatsu Wheel Loaders provides a great prevention of sliding on humid or soft ground.

Comfort of the new Komatsu Wheel Loaders are highly enhanced by the following features:

	Proportional control hydraulic system (PPC) the ease the wheel loader direction changes;
	Pressurized cabin that reduce noise to 70db (A) and protect the inside from dust and particles;
	Viscous loading system for choc and vibration reduction;
	More space for wheel loader operator;
	Greater door opening angle to ease the wheel loader access;
	Better peripheral vision.
