20.500.12556/RUL-69677 Ergonomske značilnosti traktorjev za spravilo lesa Ergonomic properties of skidding tractors Študija ugotavlja obremenitve delavcev z ropotom in vibracijami pri mehanič­nem spravi Ju 1-esa. Delovne razmere in časovno strukturo pri obsežnih snemanJ ih ropota in vibracij traktorjev primerja z obsegom in načinom mehaniziranega spravila v Sloveniji. Ugotovljeni ropot v mirovanju in obremenitev traktorista z njim presega z mednarodnim standardom dovoljene meje pri traktorju kolesniku IMT, pri goseničarju FIAT in zlasti močno pri zgibniku Timberjack. Proučene. so predvsem vertikalne vibracije na sedežu traktorjev. Največje so obremenitve traktorista z njimi pri spravilu lesa z goseničarjem. Celovita proučitev ergonomskih značilnosti treh traktorjev pokaže, da je zgibnik najbolj, goseničar pa najmanj prilagojen delavcu. The authors analyze the impact caused by noise and vibrations, experienced by workers at the mechanized wood skidding. Working conditions and time structure stated by means of extensive noise and vibration measurements are compared with the amount and kinds of skidding in Slovenia. The noise of tractors and the impact on the workers caused by it surpasses, in the cases of the caterpillar tractor FIAT, of the universal tractor IMT 558, and especially of the Timberjack the ISO standards. A speciaI emphasis is given to the research of vert i ca 1 seat vibrations occurring at tractor skidding. The highest vibration impact has been stated for the caterpillar tractor FIAT, The general investigation of all ergonomic properties proves the best suitability of the Timberjack and the worsest one of the caterpillar tractor. mehanično spravilo lesa obremenitve z ropotom obremenitve z vibracijami true false false Inštitut za gozdno in lesno gospodarstvo pri Biotehniški fakulteti Slovenski jezik Angleški jezik Znanstveno delo 2015-07-10 21:34:05 2015-07-10 21:34:05 2024-08-10 03:59:07 0000-00-00 00:00:00 1982 0 0 Str. 171-360 2 Let. 21 1982 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*37+630*30 0351-3114 1404838 Lipoglav%C5%A1ek%252cKo%C5%A1ir_1982.pdf Lipoglav%C5%A1ek%252cKo%C5%A1ir_1982.pdf 1 1CDE8FCE013312B385B8DD813F6BE96C 372d6dfbec02a8e5ef1d2f7645a6bd9c8f855b940345c5ca2d95eb96aea8d529 7006f29c-a1b3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=100963 Biotehniška fakulteta 0 0 0
