Abstract

A mobile machine, especially a self-propelling concrete pump, comprising a chassis (10) and at least one support strut (20) displaceable in a preferably horizontally oriented tubular or box-shaped telescopic section (18) between a retracted transport position to at least one extended support position, and supportable on the ground via a foot part (26) provided at its free end. In order to alter the support width across the support strut, in accordance with the invention, the support strut (30) has at least two strut parts (40, 42) which can pivot around an articulated axis (46), the axis being parallel to the vertical axis of the vehicle chassis (10).
