Abstract: A method of swing stopping control of a suspended load of a crane including a hoist and a trolley solves an equation of motion, given as an equation with respect to the deviation angle of a suspended load from the vertical direction when the trolley travels, for the trolley acceleration to thereby obtain the value of the acceleration or deceleration of the trolley, obtains speed patterns corresponding to the values of the acceleration or deceleration, drives the trolley according to the obtained speed patterns, and carries out control so that the deviation angle of the suspended load from the vertical direction becomes zero at the time when the acceleration or deceleration of the trolley is ended. Thus, even if the length of a rope holding the suspended load up is changed, a required speed pattern is produced to permit highly accurate positioning.

Abstract: A wire winding device which uses a large-sized supply bobbin, which has a large capacity and a large diameter, to highly precisely suppress a variation in tension which variation occurs when a coil is formed by winding a wire material at high speed with the wire material aligned with a winding frame. Rotation (the number of rotation, and timing) of the supply bobbin relative to rotation of the coil is controlled based on the difference between the amount of take-up of the wire material taken up on the winding frame side and the amount of pay-out of the wire material paid out from the supply bobbin, and the control is performed such that the amount of the take-up and the amount of the pay-out agree with each other every moment. This can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil and the supply bobbin.
