FORECASTING OF RISK REFUSALS OF THE BRIDGE CRANES, CONNECTED WITH EXPLOITATION
In order to forecast the risk of failures of travelling cranes and estimate their influence on the safety of working conditions, the conditions and the character of exploatation of 1225 travelling cranes which completed normative expected lifes, and are involved in constant exploitation at 105 factories of the Rostov area have been observed. During the research we developed the methods of forecast of the risk of the travelling cranes failures in view of service conditions. We found out risk factors which were connected with service conditions and caused the defects of the crane, crane runways and emergency failures of the travelling cranes. The system of failure prediction and quantitative estimation of the risk factors allows to optimize the forecast of safety working conditions for people, working in a zone of exploitation of travelling cranes, and it also can be used in supervising and control activity.
