At Bauma 2019, Liebherr will for the first time present a package of multiple intelligent assistance systems for its XPower® large wheel loaders.

These systems include new active rear person recognition and a sensor-supported, integrated tyre pressure monitoring system. All systems have been developed by Liebherr and are fully integrated into the machine control.

Another Liebherr wheel loader world premiere is a new intuitive steering system that will be available for all mid-and large-series models from Bauma 2019 onwards.

From the smallest wheel loader, the L 506 Compact, to the largest model, the L 586 XPower, Liebherr will be displaying a cross section of all wheel loader size classes at the bauma show on April 8-14 in Munich, Germany.

The small wheel loaders, up to the L 509 Stereo, and all large wheel loaders of the XPower generation will be available with Stage V emission standards compliance for the first time from April this year.

Rear person recognition

The company said: “Liebherr’s new assistance systems increase comfort and safety in daily operation in a range of ways. One of their advantages is that they enable machine operators to concentrate more on operating their Liebherr wheel loader by removing additional distractions. For example, the active rear person recognition automatically provides a warning on the machine display and sounds acoustic signals if there is danger in the wheel loader’s rear area. A special feature of this system is that it uses sensors to automatically differentiate between people and objects with the aid of sensors.”

If a person moves in the area behind the machine, the system alerts the machine operator. The active rear person recognition is activated at a greater distance than warning systems for inanimate objects such as walls or columns. The operator therefore receives a more precise warning if there is a risk of personal injury. The active rear person recognition avoids an overload of warning signals, which in turn reduces the burden on the machine operator, while reducing or eliminating serious accidents.

Tyre pressure monitoring system

“Tyres are among the most expensive wearing parts on a wheel loader. Incorrect tyre pressure leads to increased wear and rising fuel consumption and results in high costs. Other negative consequences are stability limitations and reduced manoeuvrability. It is therefore important to address potential tyre pressure problems in good time,” the company said.

Liebherr offers a new integrated tyre pressure monitoring system for this purpose, which detects tyre pressure deficiencies early, ensures good manoeuvrability and increases the lifetime of the tyres, according to the company.

With the aid of sensors, installed on the tyres and protected from damage, the system records the status of the tyres and indicates this on the machine display. If there are deviations from optimal tyre pressure, the machine operator receives a warning notification on the display. This allows the operator to act early if there is insufficient pressure or excessive temperature levels in order to avoid safety risks and high associated costs.

The integrated tyre pressure monitoring system is available as standard for many wheeled earthmovers and container handling machines across the Liebherr group of companies.
