Upravičenost potrebe pomočnika na skladišču ob kamionski cesti pri traktorskem spravilu lesa : diplomsko delo - univerzitetni študij - 1. stopnja = Assessment of the need for a helper on auxiliary storage place when conducting tractor skidding : B. Sc. Thesis - Academic Study ProgrammesKržič, MihaV proizvodnem procesu pridobivanja okroglega lesa, v primerih specifičnih prevoznih razmer ali zahtev kupcev lesa, prihaja do potreb po zagotavljanju krajših sortimentov. Pri traktorskem spravilu ... lesa je vlačenje dolgih sortimentov hitrejše in cenovno ugodnejše zato traktoristi, ob potrebi po kratkih sortimentih, opravljajo dodelavo na pomožnem skladišču ob kamionski cesti. V raziskavi se je presojalo možnost uvedbe pomočnika, ki bi izvajal dodelavo na pomožnem skladišču in s tem zvišal učinke spravila lesa s traktorjem. Na podlagi časovne študije se je ugotovilo, da je delež neproduktivnega časa pri delu brez pomočnika 26,53 % delovnega časa, pri delu s pomočnikom 37,81 % delovnega časa traktorista. Z uvedbo pomočnika se zniža poraba časa za spravilo tone lesa. Strošek delovne ure je pri spravilu brez pomočnika 42,81 %, pri delu s pomočnikom pa 60,79 %. V analiziranih delovnih pogojih, pri spravilu navzdol s traktorjem John Deere 6230 in povprečnemu posekanemu drevesu 3,02 m3 je stroškovno upravičena uvedba pomočnika do razdalje vlačenja 231,8 metrov pri razdalji zbiranja 15 metrov, razdalji vlačenja 183,6 metrov pri razdalji zbiranja 30 metrov in pri razdalji vlačenja 95,9 metrov in razdalji zbiranja 45 metrov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
