Emergency diagnostics of load-carrying structures into the works transport

Abstract

Sudden increase of exploited cranes since 1970 year and implementation of European standards restricting safety factors ware cause of many breakdowns and accidents. That’s why act about technical supervision from 2000 year impose checkups of technical conditions of supporting structures every 12 months. Checkups include also welded joint and crane tracks. Aim of routine test is to find out if there are no damages which may affect on constructions safe exploitation. Routine tests give information if construction can be exploited. Article presents methodology of diagnostics inspection for defect detection of constructions and its practical application.
