The invention discloses a working stability maintaining device for a grab bucket of a ship unloader. Through cooperation of a limiting block, a movable plate, a movable rod, a first check block, a limiting rod, a second spring and other structures, the stability maintaining effect of the device is good, when a steel cable shakes, the steel cable extrudes the second check block on one side, the second check block extrudes the second spring through a movable rod, the top pressure in the limiting block is increased, and the stability of the device is improved. The movable plate moves downwards, the movable plate pushes the movable rod to rotate, the movable rod drives the first stop block to rotate, the first stop block can stop the steel cable, and the stability maintaining effect of the device is good through cooperation of the limiting block, the movable plate, the movable rod, the first stop block, the limiting rod, a second spring and other structures. 本发明公开了一种卸船机抓斗工作维稳装置。本发明通过限位块、活动板、活动杆、第一挡块、限位杆、第二弹簧等结构配合
