桥式起重机的变频调速改造

The Reconstruction of Inverter Control Velocity System for Overhead Crane

本文介绍了变频调速系统对桥式起重机的改造,实现了起重机的平稳运行,达到了节能降耗和减少故障的目的。

This paper introduces the reconstruction that variable frequency control velocity system for overhead crane. It realizes smooth running of crane, achieves the purpose of retrenching energy reducing energy consumptions and rate of malfunction.
