The invention discloses an anti-rollover alarm system for a hydraulic supporting leg of a hoisting crane. The anti-rollover alarm system comprises the following steps of starting operation and initializing; monitoring the pressure change; switching an alarm program; comparing pressure changes; and alarm prompting; a hydraulic system structure used by the anti-rollover alarm system for the hydraulic supporting leg of the hoisting crane comprises a supporting leg, a hydraulic controller and an alarm, wherein the hydraulic controller and the alarm are installed in a crane control room, and a hydraulic cylinder is installed on the supporting leg. According to the alarm system disclosed by the invention, a first pressure transmitter and a second pressure transmitter are used for detecting the pressure values of a hoisting area and a normal pressure area in the hydraulic cylinder and comparing and analyzing the stress state of the supporting leg, thereby achieving the effect of early-warningan operator before tipping.

    本发明公开了一种起重吊车液压支腿防侧翻报警系统,包括以下步骤:开启运行并初始化;监测压力变化;报警程序切换;压力变化比较;报警提示;上述起重吊车液压支腿防侧翻报警系统所使用到的液压系统结构包括支腿以及安装在吊车控制室内的液压控制器和报警器,所述支腿上安装有液压缸。本发明通过第一压力变送器和第二压力变送器检测液压缸内起重区和常压区的压力值进行对比分析处支腿的受力状态,从而达到倾翻前对操作人员进行预警的效果。
