Abstract: A vehicle cab frame includes a base frame, with connection elements mounted on the base frame, as well as support elements mounted on the connection elements. Functional surfaces for linking attachment parts are formed on the support elements and the functional surfaces have a specified spatial orientation subject to tolerances. In order to improve the positioning accuracy of functional surfaces, the support elements are oriented and positioned relative to the connection elements so that tolerance deviations due to the construction of the base frame can be compensated by corresponding orientation and positioning of the support elements relative to the connection elements.
