The caterpillar chassis (1) for heavy vehicles, such as bucket-wheel excavators or wheeled loaders, has four caterpillars (2, 9) being arranged such that they spread out a supporting triangle (4). The front caterpillars (9), which are located at a smaller distance from the longitudinal axis (3) of the chassis, are designed for being dirigible. The swivel axis (11) of the traversing gear supported on the supporting triangle (4) is displaced out of the position (10) of the center of gravity of the supporting triangle (4) in direction to the front end (8) of the supporting triangle along the height line (7), so that the load acting on the caterpillars (2 and 9) is made more uniform.
