The invention provides a snag load device and method of a spreader and hoisting equipment. A moving mechanism and an electric driving mechanism are arranged on a hoisting equipment body, and when a snag of the spreader occurs, the electric driving mechanism is used for driving the moving mechanism to move in order to quickly release a rope, so that the downward motion of the spreader is realized, the spreader and the hoisting equipment are prevented from being damaged by the snag, and quick response can be realized through the electric driving mechanism after the snag occurs, and the loss caused by the snag is reduced to the minimum.

    本发明提供了一种吊具防挂舱装置、方法及起重设备,通过在起重设备本体上设置移动机构和电动驱动机构,在吊具出现挂舱时,利用电动驱动机构驱动移动机构运动以快速释放绳索,从而实现吊具的下降运动,以避免挂舱损坏吊具和起重设备,并且通过电动驱动机构可以在出现挂舱情况后快速响应,以将挂舱造成的损耗降至最低。
