A semitrailer (1) comprising a front end having a support and lifting mechanism (7), on the undersurface of a chassis (2), for lowering and raising the semitrailer (1) to facilitate loading and unloading of the semitrailer (1) and movement thereof. The semitrailer (1) includes an upper platform (14) which is vertically movable along poles (17, 18) of the chassis under the action of an independent pair of lifting devices. The upper platform (14) acts as an upper loading platform, in the case of vehicle transport, and as a roof structure for transport of other items. The semitrailer (1) is useful to manufacturers of articulated vehicles especially of the vehicle transporting type.
