<p>The invention concerns a machine comprising a hull (1) capable of floating on a water expanse. The hull (1) is permanently equipped with a transverse rigid axle (9) supporting two suspension arms (11) bearing wheels (2). Rubber shock absorbers (10) are inserted between the axle (9) and the suspension arms (11). The axle (9) can pivot between a rolling position and a floating position wherein the wheels (2) are raised and housed in cavities (30) arranged in the hull (1). Means are provided for manoeuvring and locking the axle (9) into one or the other of said extreme positions. The axle (9) is mounted in a recess (33) provided beneath the hull (1) and is maintained by two unsealed bearings (21). The axle (9) is equipped with a lever arm (22) to enable it to be pivoted. The recess (33) can be closed by a matching part.</p> |
