Abstract (en)
[origin: US2020080279A1] The disclosure relates to a loader working device for solving the problem of arranging the parts used in a vertical lifting mechanism of an existing loader. The loader working device comprises an accessory, an accessory overturning mechanism, and an accessory lifting mechanism including a movable arm, a movable arm oil cylinder, a front link rod and a rear link rod. The accessory lifting mechanism does not cause the accessory to interfere with a rocker arm and a front axle package of the loader working device. A connecting and mounting point of the movable arm and the accessory can be moved backwardly, thus improving a digging force and a tilting load at a low position of the loader working device.
