1. the bridge-type crane control apparatus with rocking-prevention function comprises velocity setting signal generator, speed governing unit and motor;

  • Said velocity setting signal generator is used to produce velocity setting signal initial value;

    Said speed governing unit is used for providing driving torque to arrive drive motor according to the velocity setting signal that receives;

    It is characterized in that;

    Also comprise time delay filter;

    This time delay filter receives the velocity setting signal initial value that said velocity setting signal generator sends, and this velocity setting signal initial value filtering formed has velocity setting signal after the anti-filtering of shaking effect, offers said speed governing unit.
