The invention provides a crane sudden unloading operation warning method and system and a crane, and the crane sudden unloading operation warning method comprises the following steps: obtaining the hanging load weight of the crane, and judging whether the crane is subjected to sudden unloading operation according to the change speed of the hanging load weight when the crane unloads a heavy object; acquiring specific parameters related to swing of the boom, and judging whether the crane is subjected to illegal unloading operation or not according to whether the specific parameters exceed a preset range or not when the crane is subjected to sudden unloading operation or not; and when the illegal unloading operation of the crane is judged, the alarm unit is controlled to send out corresponding alarm information. According to the crane sudden unloading operation warning method, an operator can be warned when the crane carries out illegal unloading operation, the operator is reminded to avoid repeating the illegal operation, and therefore the service life of the crane is prolonged, and the use safety of the crane is improved.

    本发明提供一种起重机突然卸载作业警示方法及系统和起重机,该起重机突然卸载作业警示方法包括:获取起重机的吊载重量,根据起重机在卸载重物时吊载重量的变化快慢,判断起重机是否发生突然卸载作业;获取与臂架摆动相关的特定参数,根据起重机在进行突然卸载作业时所述特定参数是否超出预设范围,判断起重机是否发生违规卸载作业;当判断起重机发生违规卸载作业时,控制报警单元发出相应的报警信息。该起重机突然卸载作业警示方法能够在起重机违规卸载作业时对操作员进行警示,提醒操作员避免重复该违规操作,从而提高起重机的使用寿命和使用安全性。
