Liebherr Components to Highlight Hydraulics, Digitization and Other Advanced Technologies

The components division of heavy equipment manufacturer Liebherr intends to exhibit a variety of products, many of which will showcase advancements in digitization and alternative energy.

Among the digital technologies on display will be Liebherr Components' camera monitor and surround vision systems which use sensors and software to improve visibility around machinery. An integrated digital wear measurement system will also be exhibited for the monitoring of slewing bearings, known as Bearing Clearance Monitoring (BCM). A force measurement sensor for hydraulic cylinders will be on display as well. 

The BCM is able to measure bearing wear in axial and radial directions as well as tilting clearance said Liebherr Components in a press release about the technology. "A distinct disadvantage of all common wear measurement methods is the necessity for service technicians to mount dial gauges or other measuring devices directly on the slewing bearing in the danger zone under the excavator or other machines," explained Wolfram Halder, product manager of the slewing bearings business unit in the Liebherr Components' press release. "The Liebherr BCM system makes this unnecessary, as the measuring devices are already permanently installed on the bearing."

In addition, the BCM eliminates reliance on external service providers to measure bearing clearance as a sensor is integrated into the bearing which communicates to a gateway where the data is stored and accessible via an app by machine owners. 

On the hydraulics side of things, the company has introduced a new online configurator which provides 3D models of the company's various hydraulic cylinders to aid OEMs in choosing the right cylinder for their application. Hybrid cylinders made from composite fiber are to be on display, demonstrating solutions which can provide a lightweight option to aid reductions in fuel use for machines.

An electric PTO is available to accompany these drives to operate a machine's working hydraulics. 

ZF noted in its bauma press release that efficiency will play just as integral a part in decarbonization efforts as electrification or other alternative energy systems. As such, the company continues to make improvements to so-called conventional technologies. Its ERGOPOWER powershift transmission, for instance, can help provide a fuel savings of up to 15%. 

In regards to safety, the company is working to bring many technologies developed for the passenger car and commercial vehicle segments to construction and other off-highway equipment applications. One such example is radar-based environment perception technology which will better enable machine operators to see people and objects in their vicinity. These types of technologies are also vital for the development of semi- and fully-autonomous machines and systems. 

The company also plans to launch the next generation of its Redulus4F Industrial Gearbox Series and Advanced Serviceability Solutions which provide condition monitoring. ZF said the gearbox has a flexible and compact design which allows for over 2,000 design combinations to fit OEMs' various application needs. 

Twenty sizes are available which the company said supports up to a 40% increase in torque; it features a torque range of 99-5,800 kNm. A smaller outer diameter aids with the compact design of the gearbox which is also lighter in weight and requires less packaging space to help simplify installation. 

The gearbox includes ZF's ProVID Condition Monitoring System which continually monitors operational performance. Doing so helps machine owners better manage their equipment and minimize unplanned downtime which can be costly for mining and construction operations. 

Yanmar Introducing Electrification Strategy

Equipment and engine manufacturer Yanmar has announced it will introduce its strategy for electrification of off-road machinery during bauma 2022.
