The invention relates to the technical field of lifting devices, and provides an overload detection method and an overload detection device of a lifting device in order to solve the technical problem of how to accurately detect whether the lifting device is overloaded or not, the lifting device comprises a motor and a transmission mechanism, and the transmission mechanism is connected with a rope. The overload detection method comprises the following steps: acquiring rated acceleration data of the lifting device; starting to detect the lifting acceleration of the to-be-detected load in real time when the motor is started to run, so as to obtain the actual acceleration data of the lifting device; and comparing the actual acceleration data with the rated acceleration data to judge whether the lifting device is overloaded or not.
本发明涉及升降装置技术领域,为解决如何准确地检测出升降装置是否超载的技术问题,提出了一种升降装置的超载检测方法和超载检测装置,所述升降装置包括电机和传动机构,所述传动机构连接绳索,所述超载检测方法包括以下步骤:获取所述升降装置的额定加速度数据;自所述电机启动运转时开始实时检测待检测负载升降的加速度,以得到所述升降装置的实际加速度数据;将所述实际加速度数据与所述额定加速度数据进行比较,以判断所述升降装置是否超载。
