Uporabnost traktorja Woody 140 pri spravilu lesa : diplomsko delo - univerzitetni študij = Usefulness of tractor Woody 140 for wood harvesting : graduation thesis - university studiesTrebec, SergejV avgustu 2012 so v podjetju GGP, Gozdno gospodarstvo Postojna d. o. o. nabavili nov gozdarski zgibnik Woody 140. Z uvedbo novega traktorja v proizvodni proces spravila lesa se je pojavila potreba po ... novih podatkih, s katerimi bi ugotovili uporabnost tega traktorja ter njegovo učinkovitost pri delu. Terenske meritve so bile opravljene v avgustu in septembru 2013 na območju Praprotne Drage v GGE Leskova dolina. Posnetih je bilo 90 ciklov, od tega 44 ciklov vlačenja navzgor, 22 ciklov vlačenja navzdol in 24 ciklov vlačenja po ravnem. Pri snemanju je bila uporabljena kronometrična ničelna metoda merjenja časov. Na terenu so bile posnete dolžine in nakloni vseh vlak. S strukturo delovnika je bil ugotovljen delež produktivnega časa, ki predstavlja 84 %, delež neproduktivnega pa 16 % celotnega delovnega casa. Iz izračunanih normativov za zbiranje in rampanje ter vlačenje lesa je ugotovljeno, da je Woody 140 primernejši za delo na območju jelovo-bukovih gozdov visokega krasa od njegovega predhodnika Woody 110. Za Woody 140 so izračunani tudi dnevni učinki za vse tri kategorije vlačenja lesa.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
