Abstract:The article deals with uphill wood skidding with WOODY 110 skidder and the changes taking place in technical parameters: slip, torque, tractive forces, and weight distribution of a loaded tractor in the last three meters of skidding, which is defined as a range of stopping due to overload. The test was performed on a concave skid trail, where tractor loaded with 8 meter long fir logs stopped at the 32% incline. It stopped somewhat later when skidding with butt-end forward in comparison to skidding with top-end forward. The loadweight with butt-end forward was 31.69 kN, whereas with top-end forward itweighed 33.53 kN. The measured speeds showed minute changes until the last meter, but decreased swiftly after stopping. Regarding some technical parameters, there were almost no changes at the end of stopping, two exceptions being the slip, which increased in the range of stopping, and the forward torque, which decreased in this range. The results showed that the hydrostatic transmission was efficient, considering that in a relatively well-controlled slip (the slip values increase only in the last three meters, which approximately equals the half of tractor's length) there was less grounddamage.

Title:Dinamika tehničnih parametrov traktorja WOODY 110 v območju zaustavljanja zaradi preobremenitve pri vlačenju lesa navzgor
Abstract:Članek obravnava vlačenje lesa z zgibnim traktorjem WOODY 110 navzgor, in sicer spremembe tehničnih parametrov: zdrsa, navora, vlečne sile in razporeditve teže traktorja z bremenom v zadnjih treh metrih vlačenja, ki smo ga imenovali območje ustavljanja zaradi preobremenitve. Poskus je potekal na konkavni vlaki, kjer se je traktor, ki je bil obremenjen s štirimi osemmetrskimi jelovimi hlodi, zaustavil pri naklonu 32 %, ko je vlačil les z debelim koncem naprej, in nekaj prej, ko je vlačil les s tankim koncem naprej.Breme je pri vlačenju z debelim koncem naprej tehtalo 31,69 kN, pri tankem koncu naprej pa 33,53 kN. Merjene hitrosti so skoraj do zadnjega metra pokazale majhne spremembe, nato pa so ob zaustavitvi hitro upadle. Pri nekaterih tehničnih parametrih prav tako skoraj do konca zaustavitve ne prihaja do bistvenih sprememb. Izjema je zdrs, ki v območju ustavljanja naraste, in navor spredaj, ki v tem območju upade. Rezultati kažejo, da je hidrostatski prenos učinkovit, saj z razmeroma dobro kontroliranim zdrsom (vrednosti zdrsa narastejo šele v zadnjih treh metrih, kar je enako približno polovici dolžine traktorja) prispevajo k manjšim poškodbam tal.
