Abstract
V aprilu 2010 se je na območju GE Bohor izvedlo spravilo navzgor s prilagojenim kmetijskim traktorjem Landini Vision 105 in z gozdarskim zgibnim traktorjem Woody 110. Raziskavo se je izvedla z namenom, da se ugotovi poškodbe grajenih prometnic po spravilu lesa in zdrs koles med spravilom lesa.Meritve so se izvajale pri vsakem traktorju posebej z različno velikima tovoroma (~2 m3 in ~4 m3). Ugotavljale so se razlike med uporabo in neuporabo kolesnih verig ter tlakom v pnevmatikah. Pri izmeri globine kolesnic se je ugotovilo, da so globine kolesnic pri prilagojenem kmetijskem traktorju manjšekot pri gozdarskem zgibnem traktorju. Zdrs koles je v tesni povezavi z velikostjo bremena, pri večjem bremenu je večji zdrs koles. Uporaba kolesnih verig zmanjšuje zdrs na kolesu, posledično pa povzročajo večje poškodbe gozdnih prometnic. Pri gozdarskem zgibnem traktorju je bil zdrs pri uporabi kolesnih verig pri obeh bremenih za 5 % manjši, kot pa pri neuporabi verig in pri zmanjšanem tlaku v pnevmatikah.

Abstract:
In the area of GE Bohor in April 2010, skidding up was conducted with adapted agricultural tractor Landini Vision 105 and the skidder Woody 110. The research was conducted in order to determine wheel slip and damage to roads after the harvest of timber. Measurements were performed separately for each tractor load (~ 2 m3 and ~ 4 m3). We assessed the difference between use and non-use of wheel chains and for different tire pressure. Measurements showed, that the rut depths of the adapted agricultural tractor were lower than those of skidder. Wheel slip is closely related to the size of the load, greater load results in increased wheel slip. The use of wheel chains reduces wheel slip but on the contrary causes greater damage to forest roads. Wheel slip was5% lower for both loads with skidder and the use of wheel chains in comparison to reduced tire pressure and non-use of wheel chains.
