Abstract

Namen diplomske naloge je bil ugotoviti ali različna tehnika dela vpliva na obremenitev sekača z ropotom. Glavna hipoteza diplomske naloge je bila, da nepravilna tehnika dela povečuje obremenitev sekača z ropotom. Meritve so potekale na gozdnogospodarskem območju Postojna v gozdnogospodarski enoti Planina, v sestoju smreke s primesjo bukve in jelke. Meritve so se opravile vdveh delih. Prvi dan je sekač uporabljal pravilno, drugi dan pa nepravilno tehniko dela. Vsak dan je izdelal 10 smrekovih dreves. Hkrati z meritvami ropota je potekala tudi časovna študija. Rezultati meritev so pokazali, da medobema tehnikama dela ni bistvenih razlik, večje razlike v obremenitvah sekača z ropotom so se pokazale znotraj posameznih delovnih operacij. Glavna ugotovitev diplomske naloge je, da uporaba nepravilne tehnike dela lahko zelo povečuje obremenitev z ropotom. Pri nekaterih delovnih operacijah je bila jakost ropota pri uporabi nepravilne tehnike dela celo nižja, kar se pripisujepredvsem premajhnemu vzorcu meritev. Modelni izračun obremenitve sekača z ropotom v produktivnem času je pokazal, da je razlika v dnevni obremenitvi, med pravilno in nepravilno tehniko dela le 0,19 dB(A). Kljub temu, pa je potrebno pravilno tehniko dela tudi v prihodnje zagovarjati, saj ima le-ta pozitivne učinke pri varnosti dela, težavnosti dela sekača in zmanjševanju obremenitev kostno-mišičnega sistema.

Secondary title: Impact of work tehnics on noise load of lumberman
Secondary abstract: The purpose of the research was to determine how work techniques with different noise levels influence lumberman. The main hypothesis of our graduation thesis was that incorrect work technique negatively affects lumberman with higher noise levels. Measures were taken at Postojna forestry region, at Planina forestry unit, in pine forest, with admixture of beech and fir. The measures were taken in two parts. The first day lumberman was using correct technique and the second day incorrect work technique. Each day 10 pine trees were cut down. Along with the noise measures also time studying wastaken. The results of the measures have shown that there are no essential differences between both techniques. Higher differences in noise levels were shown within separate work operations. Thus we have found out that using incorrect work technique can enlarge noise load. At some work operations noiseintensity by using the incorrect work technique was even lower, what is above all the consequence of too small research. The model of lumberman noise load in productive time has shown that the difference between correct and incorrect work technique is only 0,19 dB(A). In spite of all that, the correctwork technique should be defended, because it has positive affects on safety, on lumberman physical load and on reducing bone-muscular system load.
