AUTOMATIC ALIGNING HOISTING ACCESSORY AND HOISTING METHOD USING THIS HOISTING ACCESSORY

摘要

PROBLEM TO BE SOLVED: To provide an automatic aligning hoisting accessory whereby in case of lifting a hoist load incapable of specifying the center of gravity from outward appearance, with no repetition of test hoist required in many times of the hoist load, even in a condition deflecting the hoist load by the initial hoist, even during moving, automatically a position of the center of gravity can be efficiently adjusted, when shaking is settled, a prescribed assembly attitude is obtained. ;SOLUTION: A tilt relating to a horizontal direction of a lifted hoist load 6 is detected by a sensor 12, a detection value of tilt angle changed with time is obtained as a detection waveform, from an average deviation angle calculated from a maximum/minimum value of tilt of the detection waveform and a preset value of mounting dimension of a hoist rope preset to be mounted in the hoist load 6, an adjusting amount of hoist rope length required for restoring the lifted hoist load 6 to a horizontal position is calculated, while lift moving the hoist load 6 to a prescribed position, based on the adjusting amount, so as to make the tilt zero relating to the horizontal direction of the hoist load 6, it is restored.;COPYRIGHT: (C)1998,JPO
