Liebherr Construction Equipment Co. announced the introduction of the first wheel loader models to meet EPA Tier IV Interim emission standards on April 30.

The first of these models to be introduced to the U.S. market is the L580 wheel loader.

The new engine series features common rail fuel injection. A diesel particulate filter is used to reduce emissions further. In most applications, active regeneration can be utilized, allowing uninterrupted productivity during filter cleaning.

Additional fuel savings and performance is provided by the newly developed system “Liebherr Power Efficiency” (LPE). Drawing on the characteristic performance parameters of the hydraulic components and engine, LPE electronically ensures that the performance profile is adjusted to the maximum performance efficiency, resulting in an additional fuel savings of up to eight percent.

Liebherr continues to focus on the hydrostatic drive concept as it offers outstanding fuel efficiency, minimal tire wear and brake wear as well as exceptional traction control, according to the company. The new generation of machines has been further optimized with an increase in engine horsepower, as well as tipping load.

The cooling system remains mounted directly behind the cab with transversely mounted radiators, improving visibility. The access panels have been redesigned and are now hinged upward to make maintenance and cleaning even easier.

The operator cab remains one of the most comfortable in the industry. The new mounting system significantly reduces vibration and noise, while the new operator’s seat integrates the control console so the unit adjusts and moves as one. Multi-function joysticks, air conditioning and touch-screen display are standard.
