Between the pairs of support wheels there is a pair of drive wheels (L.sub.1). The chassis structure includes a first frame structure (P.sub.1, 14) carrying a first pair of support wheels (N.sub.1) and the pair of drive wheels (L.sub.1), and a second frame structure (O.sub.1, 10) carrying the second pair of support wheels (M.sub.1) and vertically pivotably connected to the first frame structure (at K).
