<p>Iako se poslednjih godina sve veća paţnja<br />pridaje tehnikama odrţavanja na bazi rizika, i<br />metode tehniĉke dijagnostike implementiraju<br />u sve većem obimu, a dizalice, kao grupa<br />najšire primenjenih sredstava u rukovanju<br />materijalima, uĉestvuju sa ĉak jednom<br />trećinom u svim smrtnim sluĉajevima<br />pojedinih grana industrije, razvoj modela<br />odrţavanja konkretnih tehniĉkih sistema van<br />polja nuklearne i petrohemijske industrije ne<br />napreduje dovoljno brzo. Shodno tome,<br />predmet disertacije je postavka i potvrda<br />dovoljno taĉnog i dovoljno jednostavnog<br />modela odrţavanja sistema dizaliĉnog<br />transporta za širu industrijsku primenu.<br />Novopostavljen model odrţavanja sistema<br />dizaliĉnog transporta, sadrţi dva modula -<br />tehniĉki i „menadţment― modul. Shodno<br />predloţenom tehniĉkom modulu modela<br />odrţavanja sistema dizaliĉnog transporta,<br />sprovedena je eksperimentalna provera<br />tehniĉkog modula modela in site na dva<br />sistema dizaliĉnog transporta na<br />hidroelektrani „HE Đerdap 1― u Kladovu kao<br />i provera faktora „menadţment― modula<br />primenom metoda statistiĉke analize<br />(faktorska i analiza pouzdanosti) na uzorku 51<br />preduzeća u cilju dobijanja modifikacionog<br />faktora. Vrednosti modifikacionog faktora<br />odredjuju zahvat tehniĉkog faktora (postupak<br />procene tehniĉkog faktora u celini, vizuelna<br />kontrolu stanja konstrukcije i mehanizama<br />dizalica i statiĉki i dinamiĉki proraĉun modela<br />konstrukcije dizalica ili samo vizuelna<br />kontrola).</p> / <p>Although in recent years, more attention is<br />given to risk-based techniques of<br />maintenance, and methods of technical<br />diagnostics are implemented in an increasing<br />extent, and cranes, as a group of the most<br />widely used resources in material handling,<br />account for one third of all deaths in certain<br />industries, development of specific<br />maintenance models of technical systems<br />outside the field of nuclear and petrochemical<br />industries is not progressing fast enough.<br />Accordingly , the subject of this dissertation is<br />the setting and confirmation of sufficiently<br />accurate and sufficiently simple maintenance<br />model for cranes system transportation for<br />general industrial applications. The newly<br />appointed maintenance model for cranes<br />system transportation, contains two modules -<br />technical and "management" module.<br />According to the proposed technical module<br />of maintenance model for cranes system<br />transportation the experimental verification is<br />carried out on the two cranes systems in<br />power plant "Djerdap 1 " in Kladovo while<br />'management' module factors are proved using<br />the methods of statistical analysis ( factor<br />analysis and reliability) on the sample sized<br />51 in order to obtain the modification factor.<br />The values of modification factor determine<br />the level of technical factors needed (process<br />evaluation of technical factors as a whole, the<br />visual control condition of the structure and<br />mechanisms of cranes and static and dynamic<br />analysis model construction crane or solely<br />visual inspection).</p> / null
