Abstract

L'invention porte sur un dispositif de transport, en particulier pour manipuler des cassettes, des chevalets, des conteneurs et/ou similaires, lequel dispositif comporte des moyens de déplacement (3) permettant un déplacement sur le sol, un dispositif de traction (2), équipé d'une cabine (2b) et d'une partie arrière de chargement essentiellement intégrée (2a), et des moyens de transmission de puissance pour au moins une transmission de puissance pour l'entraînement, les moyens de déplacement (3), présents dans le dispositif de transport au moins partiellement sous la partie arrière de chargement (2a), étant agencés de façon à pouvoir tourner (w) afin de permettre la direction du dispositif de transport au moins partiellement par son influence et de façon à ne pas pouvoir tourner par rapport à un axe longitudinal (s) du dispositif de transport afin au moins d'empêcher l'inclinaison de la partie arrière de chargement (2a) dans une direction transversale (p). Les moyens de mouvement (3) sont reliés à un cadre (R) du dispositif de transport par un dispositif de suspension (4), qui permet un mouvement de torsion simultané des moyens de déplacement (3), présents à des côtés opposés du dispositif de transport et étant couplés entre eux mécaniquement, la torsion ayant lieu autour d'un axe essentiellement vertical (z).
