Розробка електропривода переміщення козлового крана

Abstract

In the paper the upgrade of gantry crane. The paper presents the modernization of the electric main motion, which involves the application of smooth start in the power range of outputs and automate preparation of concrete mixes using modern programmable logic controllers. Feedback current output, can generate the required characteristics of the drive when you start it. Such modernization reducing shock loads on the mechanical mixer nodes regardless of the parameters and characteristics of the mixture, which in turn will increase the efficiency of mixer and its performance.
