Pallet deployable, non-motorized, designed for loading one or two motor vehicles for their transport within a container or an airplane pallet, the pallet comprising: - a bottom support structure and a top support structure, each capable of supporting a motor vehicle, the top support structure being provided in order to alternately move from a lower position to an upper position wherein it is maintained, raised above the bottom support structure; - two main posts and two secondary posts, which are attached at the lower ends (41, 42) thereof, respectively, at the rear, for the main posts, and at the front, for the secondary posts, of the bottom support structure, which are alternatively to be found in a lying position or an erected position, and which carry the top support structure in the upper position; - front sliding members and rear sliding members, allowing for the sliding of the top support structure along the main posts and secondary posts in order to pass from a lower position thereof to an upper position thereof and vice versa; the top support structure being a framework structure that is substantially flat, that comprises a top front wheel support device and a top rear wheel support device, that are discontinuous one from the other and intended to receive the wheels of a motor vehicle in a transportation position upon the top support structure, and that delimits a free central space as large as possible; the bottom support structure being a substantially flat structure comprising a bottom wheel support assembly intended to receive the wheels of a motor vehicle in a transportation position upon the bottom support structure; and pallet characterized: - in that in a lower position, the top support structure is nested within the bottom support structure, top front and top rear wheel support devices being inserted onto or in alignment with the bottom wheel support assembly of the bottom support structure and thus forming, together with said bottom wheel support assembly, all or part of a lower rolling path which allows for the loading onto the top support structure of a motor vehicle up to a transportation position, via the own movement thereof and without an access ramp. - a bottom support structure and a top support structure, each capable of supporting a motor vehicle, the top support structure being provided in order to alternately move from a lower position to an upper position wherein it is maintained, raised above the bottom support structure; - two main posts and two secondary posts, which are attached at the lower ends (41, 42) thereof, respectively, at the rear, for the main posts, and at the front, for the secondary posts, of the bottom support structure, which are alternatively to be found in a lying position or an erected position, and which carry the top support structure in the upper position; - front sliding members and rear sliding members, allowing for the sliding of the top support structure along the main posts and secondary posts in order to pass from a lower position thereof to an upper position thereof and vice versa; - in that in a lower position, the top support structure is nested within the bottom support structure, top front and top rear wheel support devices being inserted onto or in alignment with the bottom wheel support assembly of the bottom support structure and thus forming, together with said bottom wheel support assembly, all or part of a lower rolling path which allows for the loading onto the top support structure of a motor vehicle up to a transportation position, via the own movement thereof and without an access ramp.
