Study on safety detection method of anti-tilt lifting operation of crane

Abstract

Crane is an important equipment in engineering construction. Its anti-overturning stability is directly related to the safe operation of crane equipment. With the development of China 's social economy, ensuring the anti-overturning stability of crane equipment in work has become an important issue. This paper analyzes the anti-overturning stability of the crane, describes the model in detail, and discusses the system design. Then, the method and principle of crane anti-overturning detection are explained, and multi-sensors are used to monitor and calculate the maximum lifting weight according to ZMP theory. Finally, the simulation verification is carried out. The proportional scaling model of the crane is used to set multiple different rotation angles and calculate the corresponding maximum lifting weight. The results show that compared with the estimated value of the traditional vector method, the maximum lifting weight calculated by the ZMP method based on the swing angle is more accurate and can effectively prevent the crane from overturning.
