CONTROL METHOD OF RAIL ROPE CABLE CRANE

PROBLEM TO BE SOLVED: To provide a control method of a rail rope cable crane which can suppress the deflection of a bucket effectively in the acceleration time and the deceleration time of a traverse trolley, as well as can control the operation of the cable crane automatically. SOLUTION: The behaviors of a traverse trolley 9, a bucket 12, and the like are analyzed to model into an operation pattern, by making the delivery length of a running cable 5, the delivery length of a main cable regulation rope 8, as the calculation elements, according to the conveyance starting position and the conveyance finishing position, and when the cable crane 50 is operated, the cable crane is controlled automatically by selecting the operation pattern modeled according to the setting condition, and at the same time, the deflection of the bucket 12 is set off by a feedback control by detecting the position and the speed of the traverse trolley 9 along a main cable 7, and the deflection angle and the angular speed of the bucket 12, in the acceleration time and the deceleration time of the traverse trolley 9.
