Abstract
A construction machine () with a machine frame () and lifting columns () carrying crawler track units (). The lifting columns () include consoles () coupled in pairs to the machine frame () by articulations () and a coupling rod (). The mutual distance of the articulations () on a console () is of a length and/or the coupling rod () is of a shape that, when the crawler track units () swivel between limit positions of a swivel gear (), the coupling rod () maintains a distance to the articulations () facing the machine frame and/or to the lifting columns () over a swivelling angle range in excess of 90°, starting from the working position. The swivel gear () effects both the steering and the swivelling movements respectively in and from a transport position () to the working position and back.
