The invention provides a lifting protection method of a double-trolley bridge crane with a lifting mode. The lifting protection method comprises a lifting height protection method: monitoring the height H3 of a lifting hook of a main trolley and the height H4 of a lifting hook of an auxiliary trolley in real time; and when the absolute value of H3-H4 is greater than the height allowable deviation, controlling the lifting hook with high lifting or descending speed to decelerate or controlling the lifting hook with low lifting or descending speed to accelerate. According to the lifting protection method of the double-trolley bridge crane with the lifting mode, in the lifting mode, a lifting height protection method is adopted, the lifted object is prevented from inclining by controlling the height difference of the lifting hooks of the main trolley and the auxiliary trolley, the safety coefficient is higher, and lifting equipment and the lifted object can be effectively protected.
本发明提供了一种具有抬吊模式的双小车桥式起重机的抬吊保护方法,包括包括起升高度保护法:实时监测主小车吊钩的高度H3和副小车吊钩的高度H4;当H3‑H4的绝对值大于高度允许偏差,则控制吊钩起升或下降速度快的吊钩减速或者控制吊钩起升或下降速度慢的吊钩加速。本发明的具有抬吊模式的双小车桥式起重机的抬吊保护方法,在抬吊模式中,采用起升高度保护法,通过控制主小车和副小车吊钩的高度差,防止被吊装的物品发生倾斜,安全系数更高,可以有效地对起重设备及被吊装物进行保护。
