drva pri različitim položajima vozila i pravcima privitlavanja drva.
U istraživanju su određene granične horizontalne komponente sile u užetu te granične mase tovara koje se pri tim silama mogu privitlati uz nagib, i to u slučaju kada se i vozilo nalazi na određenom uzdužnom nagibu. Pri navedenim eksplotacijskim uvjetima narušavanje stabilnosti vozila pomakom prema nazad uvijek će biti granični uvjet privitlavanja.
Prikazani dinamički model privitlavanja predstavlja teoretski model budući, da pretpostavlja isključivo privitlavanje drva u smjeru uzdužne osi skidera ili traktora. Vrlo je čest slučaj privitlavanja drva pod određenim kutem s obzirom na uzdužnu os skidera. Pri tome također treba voditi računa o narušavanju ne samo uzdužne stabilnosti skidera, već i njegove bočne stabilnosti.
