The Application of Inverter in Portal Crane

Li Dao

Abstract

In order to ensure the reliability and high effectiveness of portal crane operation,the inverter used in the control system of portal crane is an effective solution.In the analysis of performance requirements for portal crane hoisting mechanism,a frequency control method by programmable logic controller(PLC) implementation is proposed in this paper.And the type selection,parameter setting and adjustment of inverter are presented in detail.Portal Crane working well in practice proves that the new method is effective.
