A lift device of the type appended to a vehicle such as a tailgate lift or wheelchair lift. The lift includes a platform (12) movable between a lower or ground position (G) , an upper or load position (E) and a stowed position (S). The platform (12) assumes a horizontal orientation in the ground (G) and load (E) positions and is pivotable to a vertical orientation when stowed for vehicle movement. The platform (12) is connected to a lever arm assembly(13) and further includes hydraulic apparatus (14) to move the platform (12) between ground (G), load (E) and stowed (S) positions. The hydraulic apparatus (14) is actuated by a pump and motor assembly (36) which includes an electric motor (42) for actuation of the pump (4O) and hydraulic apparatus (14). By varying the speed of the motor (42), the speed of the platform (12) between various platform orientations can be varied.

L'invention concerne un dispositif élévateur, du type accessoire de véhicule, tel qu'un haillon élévateur ou un élévateur de chaise roulante. Cet élévateur comprend une plate-forme (12) mobile entre une position basse ou au sol (G), une position haute ou de chargement (E) et une position arrimée (S). La plate-forme (12) prend une orientation horizontale dans les positions au sol (G) et de chargement (E) et pivote en direction verticale d'arrimage aux fins de déplacement du véhicule. La plate-forme (12) est connectée à un assemblage de bras de levier (13) et comprend aussi un appareil hydraulique (14) permettant de déplacer la plate-forme (12) entre les positions au sol (G), de chargement (E) et d'arrimage (S). L'appareil hydraulique (14) est entraîné au moyen d'un assemblage de moteur et de pompe (36) comprenant un moteur électrique (42) actionnant une pompe (4O). La variation de la vitesse du moteur (42) entraîne une variation de la vitesse de la plate-forme (12) entre ses différentes orientations.
