Half a century of Liebherr-Verzahntechnik GmbH means 50 years of commitment to the machinery and plant engineering industry. Gear technology originated in the technology of the revolving tower crane. Hans Liebherr wanted to buy a gear hobbing machine for gear manufacturing, but could not find what he wanted – so he simply built it himself. It’s a typical Liebherr story, since many sectors in the company group have emerged in this or in a similar way. Taking things into one’s own hands: an attitude that can still be found at Liebherr today.

Bauer Gear Motor operates two new LC 180 gear hobbing machines at its facility in Slovakia, producing gearing for all facilities. These machines are characterised by their operational versatility, given that they are used to produce around 180 different components in a very wide range of different sizes.

“The fire pump is the heart of every fire truck”, explains Michael Schöftner, Head of Mechanical Production at Rosenbauer International AG, the global leader for fire service equipment. The equipment has to withstand enormous loads in cases of operation. Rosenbauer relies on an automation solution for pump manufacturing from Liebherr. The rotary loading system RLS 800 from the Kempten-based automation experts has been deployed in Leonding near Linz for around two years now.
When Peter Pruschek, Head of Electronic and Control System Development at Liebherr-Verzahntechnik GmbH, presents the new LHGearTec control system, he first highlights the striking new features: “We are entering the market with a 24 inch touchscreen monitor – an above-average size for machine tools.

Johannes Weixler has developed a new universal chamfering application – with the dynamic mathematical assistance of colleagues.
The aircraft propulsion systems of today are wonders of technology. Since air travel is rapidly growing in demand around the world, the production technology employed until now needs to be modernised.
With the newly formed “Industrial Services” department, Liebherr-Verzahntechnik GmbH is reimagining the service ethos.
It begins with an idea. But designers often have a long way to go before a perfect workpiece is made using a suitable manufacturing process. It is good that reliable partners such as Liebherr participate and share their experiences.
For the mobility of the future, we need solutions today. Sometimes this means starting from scratch. With a new production line, new processes and new machines.
After an upgrade, the universal LC 280 DC gear hobbing machine shines with improved operating comfort and technical refinements.
