Crane anti-skew system minimizing wear of wheels[editovat]
Author: Reichl Miroslav
This thesis deals with the problem of overhead crane skew and its remedy. What is skewing, how it arises and the methods for its elimination are described in the theoretical part. Based on this it was chosen to eliminate the skewing by a method that uses a distance sensor to determine the skewing. This method is applied to the crane and two ways to control the crane motion are proposed. The control algorithms are tested on a simulation model of a crane and one of the control algorithms was implemented and tested at the real industrial overhead crane. Finally, the skew size with and without control is compared.
