The invention provides a method and device for obtaining the swing angle of a lifting appliance and an anti-swing method and device for a crane, and relates to the anti-swing field of lifting equipment. According to the method for obtaining the swing angle of the lifting appliance, track deflection change is considered when the actual swing angle of the lifting appliance is calculated, after the deflection angle of a trolley platform in the vertical direction and the to-be-optimized swing angle of the lifting appliance in the moving direction of the trolley platform are obtained, the actual swing angle of the lifting appliance is calculated according to the two parameters, and therefore the effect that the calculated actual swing angle is accurate can be guaranteed to a certain extent, and anti-swing control with the calculated actual swing angle is made more efficient. 本发明提供了吊具摆动角度获取方法及装置，和起重机防摇方法及装置，涉及起重设备防摇领域。本发明提供的吊具摆动角度获取方法，在计算吊具实际摆动角度的时候考虑到了轨道挠度的变化，进而在获取到小车平台沿竖直方向的偏转角度和吊具沿小车平台运动方向的待优化摆动角度后，依据这两个参数计算出了吊具
