Primerjava učinkovitosti, težavnosti dela in obremenitev z ropotom pri sečnji z akumulatorsko in bencinsko motorno žago [Elektronski vir] : magistrsko delo - 2. stopnja = Comparison of efficiency, psycho-physiological and noise workload when felling with electric cordless and petrol chainsaw : M. Sc. Thesis - master study programmesLipužič, BenjaminV magistrskem delu smo ugotavljali razlike v učinkovitosti in težavnosti dela ter obremenitvami z ropotom med delom z bencinsko in akumulatorsko motorno žago pri poseku dreves iglavcev in listavcev s ... prsnim premerom od tretje do šestnajste debelinske stopnje. Med desetdnevnimi terenskimi meritvami smo izdelali časovno študijo, opravili meritve pulza med delom in ropota pri sečnji z bencinsko žago Husqvarna 543 XP in akumulatorsko žago Husqvarna 540i HP, ob tem pa merili premere in dolžine izdelanih sortimentov za izračun učinkovitosti dela. Razlika v učinkovitosti dela v produktivnem času je med obema žagama statistično neznačilna, vendar pa splošnem višja pri delu z akumulatorsko žago kot pri delu z bencinsko motorno žago. V glavnem produktivnem času znaša učinkovitosti dela pri delu z bencinsko žago 6,15 min/t in pri delu z akumulatorsko motorno žago pa 5,77 min/t. Težavnost dela pri delu z akumulatorsko motorno žago je statistično značilno manjša od dela z bencinsko motorno žago, saj sta delovni in relativni delovni pulz v celotnem produktivnem času pri bencinski žagi znašala 49,4 u/min in 35,0 %, pri akumulatorski pa 45,9 u/min in 32,5 %. Obremenitve sekača z ropotom so nižje pri uporabi akumulatorske motorne žage in sicer za 5,3 dB(A) in 0,4 dB(C) v primerjavi z delom z bencinsko motorno žago. Rezultati magistrskega dela kažejo na ergonomske prednosti akumulatorskih žag, ki bodo igrale pomembno vlogo pri vse močnejši elektrifikaciji gozdarstva v prihodnosti.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
