The invention belongs to the technical field of excavators, and discloses an excavator hoisting state anti-tipping method and an excavator. The method comprises the steps that an activity area of a hoisting point on a bucket rod is established, a plurality of datum points are divided in the activity area, and the threshold pressure corresponding to each datum point is recorded; the threshold pressure is the load pressure of the movable arm large cavity when the hoisting point hoists a heavy object with the maximum weight on the premise that the excavator does not tip over, the real-time position coordinates of the hoisting point are obtained, and the load pressure of the movable arm large cavity when the hoisting point hoists the heavy object is obtained; the load pressure is compared with the threshold pressure corresponding to the closest reference point in the activity area, power interference is selectively intervened according to the comparison result, and an alarm is selectively given; the excavator applies the anti-tipping method in the hoisting state of the excavator. The method can effectively avoid tipping in the heavy object hoisting process of the excavator, and is safe, reliable, visual and accurate.

    本发明属于挖掘机技术领域,公开了一种挖掘机吊装态防倾翻方法及挖掘机,其中方法包括:建立斗杆上的吊装点的活动区域,于活动区域内划分多个基准点,记录每个基准点对应的阈值压力,阈值压力为挖掘机在不发生倾翻前提下吊装点吊装最大重量重物时动臂大腔的负载压力,获取吊装点的实时位置坐标,获取吊装点于吊装重物状态下的动臂大腔的负载压力,将负载压力与活动区域内最接近的基准点对应的阈值压力进行比较,根据比较结果选择性地介入动力干涉,并选择性进行报警;挖掘机应用上述的挖掘机吊装态防倾翻方法。该方法可有效避免挖掘机吊装重物过程中发生倾翻,安全可靠,直观准确。
