Liebherr is showcasing their comprehensive package of multiple intelligent assistance systems for their XPower large wheel loaders to construction industry professionals for the first time at this year’s upcoming Bauma Expo in Munich. These systems will include their active rear person recognition, a sensor-supported, integrated tyre pressure monitoring system, and a new intuitive steering system that will be available for all mid and large series models from Bauma 2019 onwards. All of Liebherr’s assistance systems are developed by Liebherr themselves, meaning that the technology is fully integrated into the machine controls, fully optimizing safety and comfort in their daily wheel loader operations.
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 bauma 2019. One of each of the L 509 and an L 518 models will represent the latest series of stereoloaders at Liebherr's bauma exhibition stand. 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.
Active rear person recognition helps prevent accidents that result in personal injury
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 thereby avoids an overload of warning signals, which in turn reduces the burden on the machine operator. The risk of serious accidents is reduced.
Integrated tyre pressure monitoring system increases tyre lifetime
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. Liebherr offers a new integrated tyre pressure monitoring system for this purpose. It detects tyre pressure deficiencies early, ensures good manoeuvrability and increases the lifetime of the tyres.
With the aid of sensors, which are 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. The operator can therefore 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.
New stereoloaders are premium machines in the small wheel loader sector
For decades, Liebherr’s stereoloaders have been widely recognised as productive premium machines in the small wheel loader sector. With the L 509 Speeder and the L 518 Stereo, Liebherr will be showcasing two representatives of the latest stereoloaders at bauma 2019. Liebherr has recently completely reworked the latest series, which comprises a total of four models from the L 507 Stereo to the L 518 Stereo. All models are available in a Speeder version on request. In this version, stereoloaders can reach a top speed of up to 40 km/h. This helps operators save time and enables them to move their wheel loader from one operation to the next quickly.
The stereo steering developed by Liebherr is unique. It is an ideally balanced combination of articulated steering and rear axle steering. It therefore combines the advantages of conventional articulated steering with the advantages of all-wheel steering. The resulting minimal turning circle is particularly practical when space is limited. The controlled rear axle enables Liebherr engineers to reduce the articulation angle of stereoloaders to 30 degrees. As a consequence, the centre of gravity remains in the centre of the machine even when transporting large loads, which increases stability.
