<p>The vehicle is constituted essentially by a wheeled chassis (10) and a load-carrying superstructure. The latter in turn includes a base frame (18) which is separate from the chassis. The chassis and the frame (10, 18) can be interconnected by quick-release mutual fixing means (34-36, 42-44) which can be mutually engaged and disengaged by a vertical relative movement of the chassis and the frame (10, 18). One of the chassis (10) and the frame has means for causing the vertical relative movement for engaging and disengaging the mutual fixing means (34-36, 42-44) to enable the chassis (10) to be withdrawn from beneath the superstructure frame (18) and to be reinserted beneath it. The chassis and the frame (10, 18) have mutual locating means (52-54, 56-62) such that, when the chassis (10) is inserted beneath the superstructure frame (18), the mutual fixing means (52-54, 56-62) of the chassis and the frame (10, 18) are aligned for re-engagement. <IMAGE> <IMAGE></p> |
