(FR) DISPOSITIF DE RELEVAGE AVANT POUR TRACTEUR
Abstract
(EN)
The invention relates to a front lifting device for a tractor, in particular for farming, making it possible to hitch a tool thereto and control the same, including: a chassis (1) to be attached to the bodywork of the tractor; two lower arms (2, 2') hinged to the chassis and comprising, at the end thereof furthest from the chassis, a hitching means (8, 8') for the tool; at least one working jack (4a, 4'a) in which one of the elements, a cylinder or rod, is connected to the chassis and in which the other element, a rod or cylinder, is connected to one of the coupling arms, said working jack providing the movements of the arm or arms in a working stroke between a bottom position and a raised position; the device comprises length-adjustable linking means (L) between one of the elements, a cylinder or rod, of the working jack (4a, 4'a) and one of the parts made up of the chassis or an arm, said linking means (L) being held in an extended state during a normal working mode, and being placed in a retracted state to enable the arm or arms to enter a retracted position.
(FR)
Le dispositif de relevage avant pour tracteur, en particulier agricole, permettant d'atteler et de manœuvrer un outil, comprend : un châssis (1 ) à fixer sur l'ossature du tracteur; deux bras inférieurs (2, 2') articulés sur le châssis et comportant, à leur extrémité éloignée du châssis, un moyen d'attelage (8,8') de l'outil; au moins un vérin de travail (4a, 4'a) dont l'un des éléments, cylindre ou tige, est relié au châssis et dont l'autre élément, tige ou cylindre, est relié à l'un des bras d'attache, ce vérin de travail permettant d'assurer les mouvements du ou des bras selon une course de travail entre une position basse et une position relevée; le dispositif comporte un moyen de liaison (L) de longueur réglable entre l'un des éléments, cylindre ou tige, du vérin de travail (4a,4'a) et l'une des pièces constituées par le châssis ou un bras, ce moyen de liaison (L) étant maintenu dans un état allongé pour le mode de travail normal, et étant placé dans un état rétracté pour que le ou les bras passent en une position escamotée.
