Začetek razvoja gozdarskih zgibnikov Woody sega v konec osemdesetih let, ko so slovenjgraški gozdarji pričeli z razvojem zgibnega traktorja GT-70. Posebnost stroja je, da gre za traktor s hidrostatsko-mehanskim pogonom, zaradi česar prihaja do manjših zdrsov in posledično večje učinkovitosti pogona. Z nadaljnjim razvojem traktorja je nadaljevalo podjetje Vilpo d. o. o., ki jih sedaj prodaja pod imenom Woody. Jeseni leta 2012 so v Gozdnem gospodarstvu Postojna d. o. o. začeli uvajati v proizvodnjo zgibni traktor nove serije Woody 140. Z uvajanjem novega stroja se pojavlja veliko vprašanj, med drugim je neznanka poraba goriva. Tako so analizirali porabo goriva novega stroja in ugotovili, da je poraba dokaj primerljiva oziroma celo nekoliko nižja v primerjavi z njegovim predhodnikom Woody 110. Poleg analize porabe goriva so ocenili tudi ergonomsko ustreznost zgibnih traktorjev GT-70, Woody 110 in Woody 140. Ugotovili so, da so vsi traktorji ergonomsko ustrezni in z vsako novo serijo traktorja se ustreznost še izboljšuje. The development of skidder Woody began in the late eighties when the foresters from Slovenj Gradec region began with the development of a skidder GT-70. Special feature of the machine is hydrostatic-mechanical actuator, causing minor slips and consequently greater efficiency of the drive. Vilpo d.o. o. continued further development of the tractors which are now sold underthe name Woody. In the autumn of 2012, Gozdno gospodarstvo Postojna launched in the wood production skidder of a new series Woody 140. The introduction of a new machine induced a lot of questions, including the fuel consumption. In the thesis, the analysis of the fuel consumption of the new machine was done. The results show that the consumption is fairly comparable or even slightly lower compared with its predecessor Woody 110. In addition, the ergonomic suitability of skidders GT-70, Woody 110 and Woody 140 was assessed. The results show that all tractors are ergonomically appropriate and with each new series the adequacy improves. |
