ABSTRACT:
A tractor vehicle provided with a fifth-wheel plate (4) supported by a beam (3) mounted on the chassis of the vehicle vertically pivotably in the longitudinal direction of the vehicle on two fulcrums (5) spaced-apart in the transverse direction of the vehicle. The fulcrums of the beam are selectively together or separately displaceable in the longitudinal direction of said vehicle. In this way the fifth-wheel plate is displaceable not only in the longitudinal direction (A) of the chassis by displacing both fulcrums simultaneously but also in the transverse direction (B) of the chassis by displacing only one fulcrum (FIG. 4).
