Preverjanje državnih normativov z dejanskimi učinki večbobenskega žičnega žerjava Syncrofalke na območju GG Slovenj Gradec

diplomsko delo - visokošolski strokovni študij

Abstract

Diplomsko delo obravnava strukturo časov in učinkov spravila lesa z žičnim žerjavom Syncrofalke. Delo je bilo razdeljeno na dva dela, in sicer na analizo koledarskega časa za obdobje dveh let ter na izvedbo časovnih študij. Zaradi primerjave dejanskih učinkov z državnimi normativi žičnega žerjava Syncrofalke so v analizo zajeti le dnevi, v katerih je stroj obratoval, znotraj teh dni pa so spremljani produktivni in neproduktivni časi, montaže in učinki. Na podlagi vzorčnih meritev je bila ugotovljena odvisnost produktivnih časov spravila od razdalje vlačenja, razdalje zbiranja, mase bremena ter števila izdelanih sortimentov iz posameznega bremena. Ugotovljeno je bilo, da so učinki najbolj odvisni od razdalje zbiranja, združeni operaciji zbiranja lesa pa smo pripisali največji delež v procesu spravila lesa. Izračunan je volumen ter masa posameznega bremena in povprečno breme. Analizirana je struktura produktivnih in neproduktivnih časov spravila ter faktor neproduktivnega časa, na podlagi katerih so prikazani dnevni učinki. Ugotovitve kažejo, da je faktor neproduktivnega časa dokaj visok, glavni vzrok pa so organizacijski zastoji. Opravljena je bila primerjava s predpisanimi normativi, ki so v določenih primerih dosegljivi, ponekod pa so precenjeni.

Secondary title:	Comparisson standard times with productivity for cable crane Syncrofalke in the area GG Slovenj Gradec
Secondary abstract:	My diploma thesis deals with the time and effects of wood extraction with a cable crane Syncrofalke. Diploma paper consists of two parts, namely of an analysis of calendar time for period of two years, and an execution of time studies. Due to comparison of actual effects with the national norms of cable crane Syncrofalke, only days when the cable crane was operating are taken into consideration; and within these days productive and unproductive time, assemblies and effects are regarded. Based on measurements it was discovered that productive time of skidding wood depends upon pulling distance, weight of each load and the number of items produced from each load. The results show,that effects mostly depend upon the distance of skidding, while the largest share within the procedure of wood extraction is ascribed to the united operation of skidding. Volume and weight of each load and average load was calculated as well. The structure of productive and unproductive time for skidding and the factor of unproductive time, which serve as basis for showing daily effects, were analysed. Findings indicate, that factor of unproductive time is considerably high, with organizational delays as the maincause. Comparison with determined norms showed that in certain cases they are within reach, while elsewhere overestimated.
