Abstract

Namen izuma je zasnovati k traktorju priključljiv gozdarski vitel, pri katerem navijanje vrvi (2) poteka na kontroliran način, tako da so ovoji vrvi (2) na površini navijalnega bobna (1) razporejeni drug ob drugem in brez medsebojnega križanja in prekrivanja, obenem pa je preprečena preobremenitev vlečne vrvi (2) in ostalih elementov pogonskega sklopa vitla zaradi vleke pretežkega bremena. Vitel je v ta namen v območju med zgornjim škripcem (3) in navijalnim bobnom (1) opremljen z okoli vertikalne geometrijske osi (40) prosto vrtljivim ali vsaj za ustrezen kot zasukljivim usmerjevalnim sklopom (4), ki po izbiri vključuje dinamometer (46) za merjenje natezne sile (F) v vlečni vrvi (2), tako daje tudi pogon bobna (1) lahko krmiljen v odvisnosti od vsakokrat izmerjene obremenitve vlečne vrvi (2).The purpose of the invention is to design a tractor-welded winch for the tractor, in which the winding of the rope (2) is carried out in a controlled manner, so that the ropes (2) on the surface of the winding drum (1) are arranged side by side and without cross-crossing and overlapping, the overload of the tow rope (2) and other elements of the winch drive assembly due to the tow of the heavy load is prevented. For this purpose, in the area between the upper pulley (3) and the winding drum (1), the winch is provided with a free rotating or around the vertical geometric axis (40), or at least for the corresponding rotary guide assembly (4), which optionally includes a dynamometer (46) for measuring the tensile force (F) in the tow rope (2), so that the drum drive (1) can be controlled depending on the measured load of the tow rope (2).
