Patent

CA 2258794

In the grapple of a tree harvesting machine, the feeding means (14, 15) and/or delimbing means (1, 2) are pairwise coupled in a way that the movement of the actuator (6) is transmitted to one swinging arm (5) of the pair directly and to the other one by means of a drive arm (7) and a torsion spring (18).

La présente invention concerne, s'agissant d'une moissonneuse d'arbres, une pince de débardage dont les organes d'entraînement (14, 15) et/ou les outils d'ébranchage (1, 2) sont couplés deux à deux de façon que le mouvement du vérin (6) se transmette, d'une part directement à un bras articulé (5) de la fourche, et d'autre part par l'intermédiaire d'une bielle d'entraînement (7) et d'un ressort de torsion (18) à l'autre bras de la fourche.
