Patent ID: 7721831

Claim:
Construction machine with a machine frame including a width that is suitable for transport on a transport vehicle, as well as a length in the longitudinal direction of the machine frame that is a multiple of the width, with a chassis with several ground engaging support units that support the machine frame via lifting columns, in which the ground engaging support units are capable of being swivelled from a working position transverse to the longitudinal direction of the machine frame to a transport position parallel to the longitudinal direction, and are capable of being steered in the transport position by way of a swivel gear that acts upon the ground engaging support units, characterized in that, the lifting columns include consoles, the consoles of two adjacent lifting columns are coupled, by way of articulations, with the machine frame and with a coupling rod, where the distance between the articulations on each console is of such a length and/or the coupling rod includes such a shape that, when swivelling and in the limit positions of the swivel gear, the coupling rod maintains a distance to the articulations on the machine frame and/or to the lifting columns over a swivelling angle range in excess of 90°, starting from the working position, and the swivel gear effects both the steering movement in the transport position, as well as the swivelling movement from the transport position to the working position and back.
