The invention relates to the technical field of engineering machinery, and discloses a self-checking method and a self-checking system for the weight of a suspension type movable counterweight and engineering machinery. According to the weight self-checking method for the suspension type movable balance weight, the pressure of a rod cavity of a lifting oil cylinder is detected, and then the actual lifting duration of the movable balance weight is recorded when the rod cavity has different pressure values; and then the weight condition of the movable balance weight lifted by the balance weight lifting oil cylinder at present is judged according to the change of the pressure value in the rod cavity by comparing the actual lifting duration, and automatic weight identification of the movable balance weight is achieved. Thus, the weight determined according to the pressure value of the rod cavity is matched with the manually-set weight, the manually-set weight can be corrected, the whole vehicle tipping danger caused by the fact that the weight of the balance weight is mistakenly set manually can be effectively avoided, and the operation reliability is greatly improved.

    本申请涉及工程机械技术领域,公开一种悬吊式活动配重重量自检方法、自检系统及工程机械。悬吊式活动配重重量自检方法通过对提升油缸的有杆腔的压力进行检测,然后记录有杆腔在不同压力值时活动配重的实际提升时长,再通过对实际提升时长的比较并根据有杆腔中压力值的变化判断当前配重提升油缸提升的活动配重的重量情况,实现活动配重的重量自动识别。如此,将根据有杆腔的压力值确定的重量与人工手动设置的重量进行匹配,即可对人工手动设置的重量进行校正,能有效避免配重重量因人工手动设置错误而带来的整车倾翻危险,极大地提高了作业的可靠性。
