Lifting appliance cable reel control method and device and crane

The invention provides a lifting appliance cable reel control method and device and a crane. The control method is characterized in that the operation state of a lifting appliance cable reel is controlled through a reel motor based on an emergency signal and preset operation parameters after the emergency signal transmitted by a control loop is received. According to the control method and deviceand the crane, the control precision and reliability of the synchronous movement between a lifting appliance cable and a lifting mechanism of the crane in the emergency operation mode are improved, and the labor cost is reduced. 本发明提供了一种吊具电缆卷盘的控制方法、装置及起重机，在接收控制回路发送的应急信号后，基于该应急信号及预设运行参数，通过卷盘电机控制吊具电缆卷盘的运行状态。本发明提高了在应急操作模式下，起重机的吊具电缆与起升机构的同步运动的控制精度及可靠性，降低了人工成本。
