The invention discloses a moment limiting method of a crane boom, a moment limiter and the crane boom. The moment limiting method comprises the following steps: acquiring a switching signal of an oil cylinder; acquiring the boom length of the crane boom; when the arm length reaches a set length, judging whether the switching signal is a first switching signal or not; and when the switching signal is judged to be the first switching signal, sending an output performance instruction. According to the moment limiting method of the crane boom, a length sensor is omitted, the switching signal is arranged on the change-over switch, and when the boom length reaches the set length, the affiliation of the switching signal is judged through feedback of the switching signal; whether the switching signal is the first switching signal or not is judged through the position change of the change-over switch, so that whether data information can be output or not is judged. Therefore, the cost consumed by one length sensor can be saved, and meanwhile, the reliability of the data information measured by the method is higher, and the accuracy is higher.

    本发明公开了一种起重机臂架的力矩限制方法、力矩限制器及起重机臂架,包括:获取油缸的开关信号;获取所述起重机臂架的臂长长度;在所述臂长长度达到设定长度时,判断所述开关信号是否为第一开关信号;在判定所述开关信号为第一开关信号时,发送输出性能的指令。根据本发明实施例的起重机臂架的力矩限制方法,通过取消一个长度传感器,并在切换开关上设置开关信号,当臂长达到设定长度时利用开关信号的反馈判断开关信号的归属,即通过切换开关的位置变化以判断开关信号是否为第一开关信号,从而得出是否能够输出数据信息。由此,可节约一个长度传感器所耗费的成本的同时,本方法测得的数据信息的可靠性更强,准确度更高。
