<p>The device comprises a lifting assembly (28) which includes a pneumatic lifting cell (54). The lifting cell (54) is expansible by the effect of the pressure of the com pressed air source of the vehicle for holding in the raised position the lifted axle (10) when its suspension cells (22) are load-free. The lifting assembly (28) comprises a pair of brackets (34,36), attached respectively to the body (20) of the raisable axle (10) and to a cross-member (18) of the chassis (15) adjacent to said body (20). The brackets (34,36) have respective shelf portions (50,52). The shelf portion (50) of the bracket (34) fastened to the axle body (20) overhangs the shelf portion (52) of the bracket (36) fastened to the cross-member (18). The pneumatic lifting cell (54) is interposed between the two shelf portions (50,52).</p> |
