State analysis of components of the damaged structure and integrity evaluation of braces at the spreader A2Rs – B 5500.55 + BRs
Apstrakt
Excavation, transport and spreading of barren soil and crude ore are being performed by a number of machines during the continuous production process at excavation sites, such as: bucket-wheel excava-tor; conveyor and spreader (so called ECS system). Failure of any machine in the technological chain leads to the failure of the whole system, and therefore it should be considered a structure with a serial connection. In this paper the results of non-destructive tests performed at welded joints and parent material (vi-sual testing, penetrant testing, ultrasonic testing, radiographic testing, hardness testing) on the basis of which the state analysis of components of the damaged structure, integrity evaluation of braces of the cutting and discharge boom and homogeneity of welded joints of newly _formed structures of the spreader A2Rs B 5500.55 + BRs at the excavation site 'Drnmo' near Kostolac, Serbia were perfor-med, are presented. Taking into account the fact that the user of the spreade...r does not own the design and technical documentation, all tests and researches presented in this paper were performed under the assumption that the lattice structures of both cutting and discharge boom were made of structural steels £955 and 5235, in accordance with standard EAT 10027-1.
