Sečnja in spravilo lesa s kombiniranim strojem za sečnjo in spravilo lesa HSM 805F : diplomsko delo - univerzitetni študij = Logging and skidding timber with combined machine for logging and skidding timber HSM 805F : graduation thesis - university studies
Kencijan, Saša
V Gozdnem gospodarstvu Slovenj Gradec so v letu 2010 nabavili kombiniran stroj za sečnjo in spravilo lesa HSM 805F. Namen diplomskega dela je ugotoviti uporabnost in učinkovitost stroja HSM 805F pri ...dveh različnih tehnologijah dela in primerjati stroške pridobivanja lesa pri sečnji z motorno žago in traktorskem spravilu ter raziskanima tehnologijama. Raziskava je potekala v GGE Mislinja, oddelek 01120B. Pripravljena sta bila dva objekta. Na objektu I sta potekala sečnja in spravilo kratkega lesa, na objektu II pa sečnja in spravilo dolgega lesa. Dosežen učinek pri kombinirani sečnji na objektu I je 54,96 m3/8 h, spravilu lesa pa 51,28 m3/8 h. Strošek sečnje s strojem HSM 805F je na objektu I znašal 15,41 %/m3, strošek spravila lesa pa 12,59 %/m3. Skupni strošek sečnje in spravila na objektu I je znašal 28 %/m3. V primerjavi z izračunanim stroškom dela pri sečnji in traktorskem spravilu lesa je strošek manjši za 5,49 %/m3. Na objektu II je bil dosežen povprečni učinek sečnje 68,57 m3/8 h, učinek pri spravilu lesa pa 73,04 m3/8 h. Strošek sečnje s strojem HSM 805F na objektu II znaša 12,35 %/m3, strošek spravila 11,59 %/m3, skupni strošek sečnje in spravila znaša 23,94 %/m3. V primerjavi s sečnjo in traktorskim spravilom lesa je strošek dela za 4,66 %/m3 manjši od kombinirane sečnje in spravila s strojem HSM 805F.
