SYSTEM FOR REVERSIBLE IMMOBILISATION OF A MEANS FOR HOLDING A PREFABRICATED WALL ON A MOUNTING OF A TRANSPORT DEVICE

The invention relates to a system for reversible immobilization (6), on a support (4) of a transport device (1) of at least one prefabricated wall (M), of a means for holding (3) such a prefabricated wall (M) in a vertical position. This system (6) comprises: - at least one plate (7) comprising a receiving means to receive the holding means (3); - a base (8), extending according to a plane, comprising at least one bearing means to bear against the support (4), and movable relative to the plate (7) or to the plates (7); - at least one clamping means (9) to clamp, on the support (4), the base (8) and/or the holding means (3), this under the effect of a displacement of the base (8) relative to this or these plate(s) (7). The invention further relates to a transport device (1) of at least one prefabricated wall (M) comprising at least one concrete slab or similar, this transport device (1) comprising at least one means for holding (3) this or these prefabricated wall(s) (M) in a vertical position, a support (4) and means for movement (5) of this or these holding means (3) relative to this support (4) as well as at least one reversible immobilization system (6).
