The lever jack is pivotally connected to the hydraulic cylinder and is equipped with a cutting knife. The jack comprises two double-armed levers mounted one above the other. The lower lever is located horizontally, and the lower arm of the upper lever is mounted in the initial position relative to the lower lever at an angle ??90°. Both levers are pivotally interconnected with one ends and secured pivotally with their middle parts on the housing. The fulcrum of the lower lever is made with the ability of simultaneous rotational and translational motion.EFFECT: increased felling point of tree felling time by the claw-like felling unit.1 dwg |
