In the process of crane lifting,starting as well as braking is extremely frequent,As a result,brake plays an indispensable role in the crane.In GBT 28264 "Hoisting Machinery Safety Monitoring Management" specifies firmly that in order to monitor the braking condition of the crane hoisting mechanism,it is necessary to be strict when we do failure detection and monitoring during the process of brake operation.Through the analysis the possible failures brake made,the present thesis aims to propose a method,which can take advantage of thyristor and control circuit to judge whether braking condition is good.In this way,lash to Brake Discs brought by sharp retardation is also prevented,so that the wear of brake can be reduced.Whats more,accident chance is able to cut down as well.
