The invention discloses a grab ship unloader as well as a driving method and device of the grab ship unloader. The driving method for a grab driving mechanism comprises the steps of acquiring an unloading position and an initial position of a grab; planning a moving track from the initial position of the grab to the unloading position; acquiring the pendulum length of the grab; calculating the grab starting accelerated speed according to the pendulum length of the grab and the preset moving speed of the grab; outputting a grab starting accelerated speed instruction to the grab driving mechanism according to the calculated accelerated speed; and outputting a moving instruction to the grab driving mechanism according to the planed moving track. The effect of automatically moving the grab is achieved, so that the labor intensity of operating staff is relieved, and the swing of the grab is reduced.
