Undercarriage

The undercarriage provides outstanding mobility and manoeuvrability, allowing for precise movements and slewing on the spot. It features a modular propping system for minimized stress and strain on the undercarriage, with easy adaptation to various support pads and bases. Hydraulic load distribution ensures no overloading of individual wheel sets, increasing tyre lifetime.
