Abstract

An undercarriage (10), more specifically in the form of a crawler undercarriage, comprises a main frame (14) and a first and a second sub-frame (18, 22) for supporting means, or tracks, (23, 24), that allow movement of the undercarriage, and means (27, 31, 35, 39) for supporting respective sub-frames (18, 22) which are mobile relative to the main frame (14) in order to vary the track gauge of the undercarriage. The undercarriage comprises means for positioning and securely holding a respective sub-frame (18, 22), in at least one intermediate position (I) between a first position (R) and a second position (E).
