The invention relates to a method, device and system for controlling a crane and a storage medium. The method comprises the following steps: acquiring a first speed value of a first motor, wherein the first motor is configured to pull a first end of a lifting appliance of the crane; acquiring a second speed value of a second motor, wherein the second motor is configured to pull a second end of the lifting appliance of the crane, and the second end is the opposite end of the first end in the trolley running direction of the crane; acquiring a first speed difference between the first speed value and the second speed value; acquiring a first speed difference threshold value; and if a first speed difference between the first speed value and the second speed value is smaller than the first speed difference threshold value, sending a control instruction to the first motor to increase a torque output value of the first motor in the trolley running direction. According to the technical scheme, the lifting appliance of the crane is effectively prevented from swinging.
本申请涉及控制起重机的方法、装置和系统以及存储介质。该方法包括:获取第一电机的第一速度值,第一电机被配置为拉住起重机的吊具的第一端;获取第二电机的第二速度值,第二电机被配置为拉住起重机的吊具的第二端,第二端是第一端在起重机的小车运行方向的相对端;获取第一速度值与第二速度值的第一速度差;获取第一速度差阈值;并且如果第一速度值与第二速度值的第一速度差小于第一速度差阈值,向第一电机发送控制指令以在小车运行方向增加第一电机的转矩输出值。本申请技术方案有效防止起重机吊具摇摆。
