Abstract

La présente invention concerne une plate-forme de chariot et son procédé de fixation pour fixer la plate-forme du chariot sur l’embase du chariot. La plate-forme comprend au moins un cadre extérieur constitué d’une paire de poutrelles de structure longitudinales et d’une paire de poutrelles de structure transversales, et au moins deux grilles centrales, dont les extrémités sont reliées sur les poutrelles de structure transversales entre les poutrelles de structure longitudinales. Le procédé de fixation comprend : une bielle qui est montée amovible dans l’une des extrémités des grilles centrales ; deux systèmes de liaison reliés sur chaque extrémité de la bielle, chacune étant munie d’une fiche de verrouillage, un ressort monté autour d’une extrémité de la bielle, et deux extrémités du ressort qui butent contre le système de liaison et les grilles centrales ; des localisateurs sur lesquels est présente une encoche de localisation s’adaptant à la fiche de verrouillage. Les localisateurs sont montés sur l’embase du chariot à des positions prédéterminées correspondants aux fiches de verrouillage, dans lesquels les fiches de verrouillage peuvent être déplacées selon les encoches de localisation pour les verrouiller ou les dégager des encoches de localisation. Ainsi, la plate-forme est fixée ou relâchée selon l’embase du chariot.
