Configuring the algorithm of the load limiter with intermediate threshold

Abstract

The problem of low quality of the operation of load capacity limiters is revealed due to incorrect tuning of its algorithm parameters. The technique of determining the parameters of the algorithm with an intermediate threshold is developed. The realization of the method is based on the information of the load and speed sensors of the lifting mechanism. Based on the methodology, the algorithm for automatic calculation of the intermediate threshold and the unconditional interdiction threshold is developed. For a real crane the parameters of the rated capacity limiter algorithm are calculated. The comparison of the algorithm parameters with the values obtained by the empirical method is carried out. Conclusions are made about the applicability of the developed methodology.
