变频器在塔式起重机起升机构的应用

Application of Frequency Converter at Tower-Type Hoist Lifting Structure

本文介绍目前国内塔机起升机构几种主要调速方式,指出了各种方式的优劣和适用范围;针对4绳最大起重量小于等于6t的小中型塔机提出了使用交流变频调速方式,使用矢量变频器实现,给出了完善的解决方案。

Several main speed control methods of domestic tower type hoist lifting structure have been described, in regard to every method, advantages and disadvantages and scope of application have been pointed out. In view of 4-rope small and medium tower-type hoist with the maximum hoist weight equal or less than 6 tons, AC frequency converter speed control could be used, so that vector frequency converter could be realized, with well and sound solution scheme be provided.
