Obremenitve traktorista pri spravilu lesa : diplomsko delo (univerzitetni študij - 1. stopnja)

Žunič, Gregor (author), Potočnik, Igor (mentor)

Leta 2009 je bila narejena raziskava na gozdnih delavcih - traktoristih pri traktorskem spravilu lesa. Raziskovalni objekti so se nahajali na območju visokega krasa na GGO Postojna, Novo mesto in Kočevje. Obremenitve traktoristov med spravilom lesa so bile merjene s štirimi prilagojenimi kmetijskimi traktorji ter dvema zgibnikoma. V prvem delu diplomske naloge je predstavljena splošna slika traktoristove fizične obremenjenosti ter obremenjenosti z vibracijami in ropotom po posameznih delovnih operacijah ter delovnih postopkih. Izračunana je tudi modelna obremenjenost z vibracijami. Primerjana je z veljavnima Pravilnikoma. Ugotovitve kažejo, da je traktorist vdanih delovnih razmerah preobremenjen tako fizično kot tudi z ropotom in vibracijami. V drugem delu diplomske naloge pa je narejena primerjava fizične obremenjenosti traktorista ter obremenjenosti z ropotom in vibracijami glede na posamezen traktor. Primerjava traktorjev je pokazala, da pri sedanjem nivoju znanja ne moremo zagotovo napovedati, kateri traktor bo v danih delovnih pogojih za traktorista najbolj ergonomsko primeren.

Abstract

Researches were made on tractor drivers in year 2009. Objects were located at the area of Slovenian high carst in GGO Postojna, Novo mesto and Kočevje. Loads were measured by timber harvest on 4 adjusted agricultural tractors and 2 skidders. First part of this gradual thesis presents overall structure of physical loads, loads by vibrations and loads by noise by individual working operations and working procedures. Calculated modular loads by vibrations and by noise were compared with valid standards. The analyzes of results show us that tractor drivers were over loaded physically, by vibrations and by noise. Loads by each tractor are present in the second part. The analyses of results show us that with a current level of knowledge we can not certainly predict which tractor is the best to work within different working environments.
