Plate carrier for plate fixing device

A plate carrier for mounting at an upper end of an upper element of a central pole of a plate hoist device, comprising at least one longitudinal central body formed by two substantially rectangular plates separated by three longitudinal walls forming two central sheaths and two peripheral grooves, each central sheath accommodating a generally T-shaped transverse arm which includes a longitudinal median branch slidably mounted in the sheath and a transverse tubular part welded to a free end of the median branch, said transverse tubular part extending substantially in a plane of the central body and further comprising first two transverse arms articulated respectively around an axis rigidly connected to free ends of the central body in a first peripheral groove and second two transverse arms articulated respectively around an axis rigidly connected to the free ends of the central body in an opposite second peripheral groove, wherein each first arm comprises at a free end thereof, a stop extending orthogonally to the first arms and to the plates forming the central body, and wherein edges of the rectangular plates comprise in a median part thereof a substantially rectangular cutout, substantially matching a depth of the first peripheral groove, said cutout allowing stops which project from the free ends of the second arms to pass when said arms are folded away in said first peripheral groove.
