Cat®-Motor Grader 120M2 retrofitted with air brake system
Calle, June 2019. The Graz-based branch of Zeppelin Österreich GmbH are having their Cat® Motor Grader 120M2 retrofitted with Dipl.-Ing. Tietjen GmbH air brake systems.
The 20 metric ton, 10 m vehicles can be controlled and safely driven with the compressor roller attachment on roads and doing forestry work in Alpine surroundings.
Thanks to a high production depth, Tietjen GmbH is in a position to produce reliable, exact tailor-made components for this retrofit: Using the latest 3D design software, the Development department first designed the mounts, support plates and plumbing installations which were then manufactured with the company’s own CNC turning and milling machines, a CNC pipe-bending machine and a range of different drilling and punching machinery.
These components, as well as others, and 7 m long hoses could be adapted to the available space in the centre pivot steered vehicle with non-contact integration.
