The embodiment of the invention provides a crane and a control method thereof. The crane comprises a machine body, a boom, a luffing mechanism, a tension sensor and a controller, and one end of the boom is rotatably connected with the machine body; the luffing mechanism is respectively connected with the machine body and the boom; the tension sensor is arranged on the luffing mechanism and is usedfor detecting a tension value of the luffing mechanism to the boom; and the controller is electrically connected with the tension sensor and the luffing mechanism, and the controller is set to determine that the boom length of the boom exceeds a boom length threshold value if the tension value is greater than the tension threshold value. According to the crane and the control method thereof provided by the embodiment of the invention, the tension value of the luffing mechanism to the boom is detected through the tension sensor, and whether the boom length of the boom exceeds the boom length threshold value or not can be determined according to the tension value, so that the problem of overload damage of the boom is avoided.

    本发明实施例提供一种起重机及其控制方法,起重机包括机身、臂架、变幅机构、拉力传感器以及控制器,臂架的一端转动连接机身;变幅机构分别连接机身和臂架;拉力传感器设置于变幅机构,拉力传感器用于检测变幅机构对臂架的拉力值;控制器电性连接拉力传感器和变幅机构,控制器被设置为若拉力值大于拉力阈值,则确定臂架的臂长超出臂长阈值。本发明实施例提供的起重机及其控制方法,通过拉力传感器检测变幅机构对臂架的拉力值,并且根据拉力值能确定臂架的臂长是否超出臂长阈值,从而避免出现臂架过载损坏的问题。
