The invention relates to a crawler vehicle having a chain drive with two closed chains (110) which are arranged spaced apart in the vehicle transverse direction and which are guided in each case at a first end around a drive wheel (112) and at a second end around a guide wheel (114), and which are designed to be supported against the ground in a ground-side chain section (110a) between the drive wheel (112) and the guide wheel (114). According to the invention, in each case at least one support rail (130) which extends in the vehicle longitudinal direction is arranged between the drive wheels (112) and the guide wheels (114), which support rail (130) is designed to bear permanently against a contact section (110d) of the respective ground-side chain section (110a). The invention also relates to the use in particular for snow-going crawler vehicles, for example piste grooming vehicles.
