The invention discloses a safety prevention method used for skip hoisting. The safety prevention method comprises the following steps: while a skip is in a no-load state, picking up a lifter motor current signal for lifter operation as a base value, and judging that the skip is not in the no-load state and directly picking up the current signal while the picked-up lifter motor current signal for lifter operation is smaller than 2/3 of the base value. A weighing sensor does not need to mount any more, and thus, a safety prevention effect for skip hoisting is improved.

    一种用于箕斗提升的安全防范方法,其步骤是:当箕斗处于空载状态时,拾取提升机运行的提升机电机电流信号为基准数值,当拾取提升机运行的提升机电机电流信号为小于2/3的基准数值时,判定箕斗未处于空载状态,直接拾取电流信号,不再安装称重传感器,因此提高了对箕斗提升的安全防范效果。
