The invention relates to the related technical field of engineering machinery, in particular to a crane falling amplitude control method and device and a crane. The method comprises the steps that firstly, the target falling amplitude speed at which a driver wants to make the crane run is determined through the opening degree of a handle; and then according to the working condition data of the crane and the target amplitude falling speed, the through-flow area of the balance valve is determined and controlled to be kept at the target through-flow area capable of enabling the crane to fall at a constant speed at the target amplitude falling speed, so that the constant-speed amplitude falling of the crane is automatically controlled, and the amplitude falling stability and safety of the crane are greatly improved.

    本申请涉及工程机械相关技术领域,具体涉及一种起重机落幅控制方法、装置和起重机,该方法包括首先通过手柄开度确定驾驶员想要使起重机运行的目标落幅速度;然后根据起重机的工况数据、目标落幅速度确定并控制平衡阀的通流面积保持在能使起重机以目标落幅速度匀速落幅的目标通流面积,从而自动控制起重机匀速落幅,大大提高了起重机落幅的稳定性和安全性。
