  • the two centrally arranged tubes 27b offer sufficient strength to be gripped from underneath by the support platform of the lifting and transport vehicle, with the result that the shelf 1 is lifted.
  • the lower shelf 10 is designed in such a way that its underside extends in the uniform horizontal plane E at least in a central region. It is important that the underside of the floor rests on those sections of the rectangular edge of the Floor, which are located between the vertical supports 2, is arranged at least level with the horizontal plane E or higher.

Abstract

L'invention concerne un rayonnage mobile pour le stockage de marchandises, comprenant quatre supports verticaux (2) aux coins du rayonnage et des tablettes positionnées à différentes hauteurs, la tablette la plus basse présentant une distance verticale par rapport au sol environnant, de sorte qu'un véhicule de levage et de transport peut passer sous ladite tablette la plus basse, les autres tablettes étant chacune constituées de quatre entretoises (30), qui sont fixées aux supports (2), et d'une base pour les marchandises. Chaque support (2) consiste en un élément profilé angulaire composé exclusivement de deux pattes profilées (21) à angle droit l'une par rapport à l'autre, chaque patte profilée étant pourvue d'ouvertures (18), qui forment un motif longitudinal, pour la fixation par emboîtement des entretoises (30). Chaque entretoise (30) est constituée d'une partie centrale allongée (31) et de parties terminales (32) aux deux extrémités. Au moins deux éléments de liaison par verrouillage (35A, 35B) sont formés sur chaque partie d'extrémité (32), pour fixer la partie d'extrémité à la patte profilée (21) en question. Les éléments de liaison par emboîtement sont situés à des hauteurs différentes et forment une liaison par emboîtement avec des ouvertures (18) dans la patte profilée (21), lesquelles ouvertures sont également situées à des hauteurs différentes.
