THE SIGNIFICANCE OF NON-DESTRUCTIVE TESTING OF CRANE LIFTING EQUIPMENT

Abstract

Regular inspection and verification of lifting equipment is major to ensure the safe use of equipment. The inspection includes: visual inspection, dimensional testing, functional tests, equipment disassembly, electrical testing, and non-destructive testing (NDT). Materials that are used in the production of lifting equipment are liable to wear, deformations, cracks, and damage. Material fatigue or corrosion cracks are undetectable through visual inspection or disassembly, due to their characteristic of camouflage. Different studies showed that visual inspections are insufficient, so the focus should be on the direction of internal damage within certain components. Non-destructive testing is a method that can detect hidden defects in materials and elements. This research aims to show the classification of non-destructive testing, its advantages, the results of tests, and the most effective NDT methods for testing crane components
