The crawler-tracked carriage comprises at least one crawler track having a beam secured to the platform (20) and carrying at is ends two wheels (13, 14) about which there extends a catenary assembly (15). According to the invention the beam is composed of at least two beam segments (11, 12) connected together at a common end such as to be able to oscillate mutually about a first substantially horizontal, transverse axis (A1). A first beam segment (11) is secured to the platform (20) by a hinge (VS) having a second axis of oscillation (A2) parallel to and distant from said first axis (A1), the second beam segment (12) being secured to the platform (20) by a linkage (V3) which has a third axis of oscillation (A3) parallel to and distant from said first axis (A1), and is able to slide in a direction having at least one longitudinal component.
