Smotrnost izvoza sečnih ostankov z zgibnim polprikoličarjem Ponsse Elk [Elektronski vir] : diplomsko delo - univerzitetni študij - 1. stopnja = Expedience of transporting wood residues from forest with Ponsse Elk forwarder : B. Sc. Thesis - academic study programmesLever, GašperZaradi varstva gozdov pred podlubniki se je v zadnjem času po zaključeni strojni sečnji in spravilu okroglega lesa z zgibnim polprikoličarjem pričelo še spravilo sečnih ostankov. Ker se pri izvozu ... sečnih ostankov poraja vrsto vprašanj iz različnih vidikov, je bil namen diplomskega dela ugotoviti smotrnost tega dela. Tako smo v raziskavi izdelali časovno študijo izvoza sečnih ostankov z zgibnim polprikoličarjem Ponsse Elk, ugotovili težavnost dela, vpliv izvoza na gozdna tla ter po sekanju sečnih ostankov in prodaji sekancev še ekonomičnost izvoza, glede na odkup na gozdni cesti ter energetsko vrednost porabljenega goriva in sekancev. Iz delovišča, se je po naših ocenah izvozilo 37.642 kg sečnih ostankov, iz katerih se je nato izdelalo 37.035 kg sekancev. Ugotovili smo, da je bil strošek izvoza za 262,1 € večji od odkupne cene sekancev na gozdni cesti. Učinkovitost izvoza je bila v produktivnem času 7,6 min/t in 10,3 min/t v delovnem času. Energetska vrednost proizvedenih sekancev je za 162-krat presegla energetsko vrednost porabljenega goriva pri izvozu. Težavnost dela ni presegala dopustnih obremenitev in je podobna težavnosti pri izvozu okroglega lesa. Po izvozu sečnih ostankov, se je globina kolesnic na gozdnih vlakah in sečnih poteh v povprečju povečala za 0,9 cm, širina poti pa za 1 cm. Tako smo prišli do zaključka, da ima izvoz sečnih ostankov pozitivno energijsko bilanco, ima pa lahko negativen vpliv na ekonomiko dela kot tudi okolje.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
