- Abstract
The screw connecting rod of a hoisting machine suddenly breaks during the service at temperatures below 20 °C. In this article, the fracture surface, material , heat treatment process and mechanical properties of the connecting rod are analyzed. We find the low temperature brittle fracture of the screw is mainly caused by too large unbalanced load due to improper operation. The incorrect heat treatment process of the screw is one of the reasons for its fracture.
