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.

“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.

Wenzel GearTec GmbH, a successful manufacturer of gear inspection machines, has been part of Liebherr-Verzahntechnik GmbH since May 2019. The Karlsruhe-based company has specialised in the measurement of gears, gear cutting tools and other rotationally symmetrical workpieces since 2004 and has an innovative product range that perfectly complements Liebherr's own.
