Časovna študija spravila lesa v jelovem gozdu z gozdarskim zgibnikom Bijol BWS 160 : diplomsko delo - visokošolski strokovni študij - 1. stopnja = The time study of timber skidding in fir forest with forestry skider Bijol BWS 160 : B. Sc. Thesis - Professional Study ProgrammesJankovec, ViljemLeta 2016 je slovensko podjetje Bijol na trgu ponudilo nov izdelek, zgibni traktor Bijol BWS 160. Stroj so kupili tudi v podjetju SiDG, kjer je nastala potreba po študiju dela na tem gozdarskem ... zgibniku. Delo smo opravljali v gozdnogospodarski enoti Javornik. V raziskavi smo ugotavljali strukturo delovnega dne pri spravilu iglavcev in učinke spravila glede na različne smeri spravila, razdalje vlačenja, naklone vlak in razdalje zbiranja. V petih snemalnih dneh smo izmerili 1300,20 minute delovnega časa, 1030,8 minute produktivnega časa, opravili smo 38 ciklov spravila lesa, v katerih smo pospravili 191,4 m3 sortimentov. Ugotovili smo, da je v povprečnem delavniku 65,22 % produktivnega časa, delež neproduktivnega pa 34,78 %. Povprečno breme v naši raziskavi je znašalo 5,04 m3, največje 8,04 m3, najmanjše pa 1,37 m3 pri povprečni spravilni razdalji 311 m in povprečni razdalji zbiranja 28,6 m. Ugotovljeni povprečni dnevni učinek je bil 36,37 t oziroma 38,28 m3, medtem ko je povprečna učinkovitost dela v produktivnem času znašala 5,38 min/m3, v delovnem času pa 6,82 min/m3. Učinek dela najbolje pojasnimo s spremenljivkami razdalja vlačenja, razdalja zbiranja, masa bremena ter število kosov v bremenu.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
