Abstract: An articulated/swivel joint for the articulated connection between a rear section and a front section of a construction machine includes a joint mechanism assigned to a swivel-stop arrangement for limiting the swivel movement of a front joint part in relation to a rear joint part. The swivel-stop arrangement includes a first swivel stop for predetermining a maximum amount of swivel deflection during deflection of the front joint part in relation to the rear joint part in a first swivel-movement direction and a second swivel stop for predetermining a second maximum amount of swivel deflection during deflection of the front joint part in relation to the rear joint part in a second swivel-movement direction. When an articulated movement is performed, the maximum swivel-deflection range decreases as the amount of articulated deflection increases, starting from a neutral position of articulation of the front joint part in relation to the rear joint part.
