20.500.12556/RUL-17797 Obremenitev delavca z ropotom in s tresenjem pri gradnji gozdnih vlak z gradbenimi stroji diplomsko delo - visokošolski strokovni študij - 1. stopnja Z diplomsko nalogo so želeli prikazati in ugotoviti, kakšnemu ropotu in tresenju je izpostavljen delavec v gradbenem stroju pri izdelavi vlake. Glavna hipoteza naloge je bila, da obremenitve ne bodo presegle mejnih in opozorilnih vrednosti, ki jih predpisujeta pravilnika o varovanja zdravja delavcev s področij hrupa in vibracij. Meritve so opravili na dveh deloviščih,v GGO Slovenj Gradec in v GGO Kočevje. V GGO Slovenj Gradec so bila tla mehka in neskalnata, v GGO Kočevje pa je bila podlaga kamnita. Meritve in časovno študijo so opravili na dveh bagrih, prvi Takeuchi in drugi Caterpillar, z različnima strojnikoma. Do največjih obremenitev z ropotom je na Koroškem prihajalo med prazno vožjo (76,12 dB(A)), na Kočevskem pa med premikom z mehanskim drobljenjem (79,86 dB(A)). Največje obremenitve s tresenjem je na Koroškem povzročala priprava terena (1,20 m/s2) in na Kočevskem premik (1,24 m/s2). Meritve so pokazale, da v obeh primerih spodnji mejni vrednosti za ropot (80 dB(A)) nista bili prekoračeni. V obeh primerih sta bili prekoračeni opozorilni vrednosti dnevne izpostavljenosti, normalizirani na referenčno obdobje 8 ur (0,5 m/s2) tresenja celotnega telesa, ne pa mejni vrednosti dnevne izpostavljenosti za 8 ur (1,15 m/s2). The research was done, to show and determine what noise levels and vibration levels the excavator operator is exposed during construction of skidding roads. The main hypothesis was that the values measured in the field would notexceed the action and limit values determined by Slovenian law acts on workersʼ health. Measurements were performed at two sites, at the forest management unit (FMU) Slovenj Gradec and at FMU Kočevje. At FMU Slovenj Gradecthe soil structure was soft and stone-less, at FMU Kočevje the soil basis was heavily rocky. The measurements and a time study were made for two different excavators (Takeuchi TB 070, Caterpillar 323 D) with two different operators. The highest exposures to noise were measured at FMU Slovenj Gradec during the movement of the excavator (76.12 dB(A)), at FMU Kočevje during shifting and mechanical chorusing of rocks at the same time (79.86 dB(A)). The highest exposures to vibrations were measured at FMU Slovenj Gradec during displacement of logging residuals and wood from construction area (1.20 m/s2) and shifting of excavator between operations at FMU Kočevje (1.24 m/s2). Estimated daily noise exposure level corrected with impact of impulsive noise didnʼt exceed lower exposure action values (80 dB(A)) at any excavator (77.06 dB(A), 79,97 dB(A)). On the contrary exposure to whole-body vibrations (0.78 m/s2, 0.97 m/s2) did exceed daily exposure action value (0.5 m/s2), but not limit value (1.15 m/s2). ergonomija gozdne prometnice gradnja vlak obremenitev z ropotom obremenitev s tresenjem true false false [L.
