Produktivnost in poraba časa pri izdelavi prostorninskega lesa s cepilnikom Lancman : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Productivity and time consumption of stacked wood production using Lancman woodsplitter : B. Sc. Thesis - Professional Study ProgrammesVerbič, KlemenNamen diplomskega dela je bil ugotoviti, ali drevesna vrsta vpliva na proces izdelave polen. Naredili smo poskus, v katerem smo iz 5,13 m3 okroglega lesa izdelali polena, dolžine 0,5 m, pri čemer smo ... ugotavljali porabo goriva in maziva za motorno žago in traktor, ki je poganjal cepilni stroj, ter porabo elektrike pri krožnem žagalnem stroju. Podatke o potrebnem času smo pridobili z metodo časovnih študij. V delovnem času smo ugotovili učinkovitost dela za delovni čas 0,56 m3/h ter za produktivni čas za izdelavo iglavcev in listavcev skupaj 0,67 m3/h. Produktivnost izdelave polen listavcev je bila manjša (0,59 m3/h) od izdelave polen iglavcev (0,80 m3/h). Pri iglavcih je cepljenje polen učinkovitejše (2,16 m3/h) kot pri izdelavi listavcev (1,59 m3/h). Razlika ostane tudi, če v cepljenje vključimo še čas prelaganja in odmetavanja; tako je produktivnost cepljenja pri iglavcih 1,67 m3/h in pri listavcih 1,14 m3/h. Ugotovljena učinkovitost dela z motorno žago znaša 5,2 m3/h pri iglavcih in 4,94 m3/h pri listavcih, medtem ko učinkovitost dela s krožnim žagalnim strojem za iglavce znaša 2,49 m3/h in za listavce 1,83 m3/h. Poraba goriva za pogon cepilnika s traktorjem z močjo 25 kW je znašala 439 ml/m3 za celoten poskus. Ugotovljena poraba mešanice za prežagovanje okroglega lesa je bila 159 ml/m3 in poraba maziva za verigo motorne žage 46 ml/m3. Poraba energije za krožni žagalni stroj je znašala 0,514 kWh/m3 za iglavce in 0,749 kWh/m3 za listavce.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
