In order to provide a crane with a winding and lifting synchronous tuning function, which enables the load sharing of each lifting hook to be synchronously tuned when more than three lifting hooks are used for carrying out combined lifting linkage, the speed control of winding and lifting motors (IM) of a plurality of lifting hooks (H) is respectively controlled so as to control the speed of the winding and lifting motors (IM) during winding and lifting. The speed is slowed down when the load of the motor is increased, the speed is increased when the load of the motor is decreased, and the speed is increased when the winding falls down and the load of the motor is increased, and the speed is slowed down when the load of the motor is decreased, so that the operation is carried out in the following manner: when the winding is lifted and the lifting is combined, the speed is increased when the winding falls down and the load of the motor is decreased. The speed of the hook (H) with the load sharing larger than that of the other hook (H) is slower than that of the other hook (H), the speed of the hook (H) with the load sharing smaller than that of the other hook (H) is higher than that of the other hook (H), and the speed of the hook (H) with the load sharing larger than that of the other hook (H) is higher than that of the other hook (H) during winding and falling combined hanging linkage. The speed of the hook (H) whose load sharing is smaller than that of the other hook (H) is slower than that of the other hook (H), thereby enabling the plurality of hooks (H) to share the load with each other when the plurality of hooks (H) are combined and linked.

    本发明为了提供在利用三个以上的吊钩进行合吊联动时使各吊钩的负荷分担进行同步谐调的带卷绕提升同步谐调功能的起重机,针对多个吊钩(H)的卷绕提升电动机(IM)的速度控制,通过分别控制成在卷绕提升时,在电动机负荷变大时速度随之变慢,在电动机负荷变小时速度随之变快,并且在卷绕下落时,在电动机负荷变大时速度随之变快,在电动机负荷变小时速度随之变慢,由此,通过分别以如下方式进行动作,即:在卷绕提升合吊联动时,载荷分担比其他吊钩(H)大的吊钩(H)的速度与其他吊钩(H)相比变慢,载荷分担比其他吊钩(H)小的吊钩(H)的速度与其他吊钩(H)相比变快,并且在卷绕下落合吊联动时,载荷分担比其他吊钩(H)大的吊钩(H)的速度与其他吊钩(H)相比变快,载荷分担比其他吊钩(H)小的吊钩(H)的速度与其他吊钩(H)相比变慢,由此,在多个吊钩(H)的合吊联动时,使多个吊钩(H)相互分担载荷。
