Spravilo in prevoz lesa z gozdarsko polprikolico Farma : diplomsko delo - univerzitetni študij

Kimovec, Aljoša (author), Košir, Boštjan (mentor)

V diplomskem delu so predstavljene gozdarske polprikolice, naštetih je nekaj največjih proizvajalcev gozdarskih polprikolic na slovenskem in evropskem trgu, predstavljeni so posamezni modeli gozdarskih polprikolic in opredeljene so njihove tehnične značilnosti. Gozdarska polprikolica Farma nosilnosti 12 tz dvigalom C6-5D v kombinaciji s traktorjem Valtra N92 je bila uporabljena zaterenska snemanja, posnetih je 10 uporabnih ciklusov, kjer so izmerjeni časiposameznim delavnim operacijam. Izračunane so količine prepeljanega oz spravljenega lesa ter analizirani so časi, pridobljeni z meritvami. Ugotovljenje glavni produktivni čas v odvisnosti od spravilne razdalje oz. transportne razdalje ter pomožni produktivni čas v odvisnosti od velikosti bremena. Izračunani so možni učinki glede na velikost bremena ter spravilno oz. transportno razdaljo. Izračunana je gospodarnost gozdarske polprikolice v kombinaciji s traktorjem, uporabljene pri terenskih snemanjih, gozdarska polprikolica s traktorjem je primerjana s kamionskim prevozom, med traktorskimin kamionskim prevozom je ugotovljena konkurenčnost.

Abstract

Graduation thesis is presenting forestry trailers, listed are some of the biggest manufacturers of forestry trailers in Slovenia and Europe, and some models of forestry trailers and their technical characteristics. Forestry trailer Farma, with load capacity of 12 t and with the crane C6-5D in combination with the tractor Valtra N92 was used for field measurements. Measurements were made in 10 cycles, in which time between different operations was measured. Calculations were made, how much wood was transported/harvested, and analysis of data that was obtained with measurements. Main productive time was identified in dependence with skidding distance/transportation distance. Also auxiliary productive time was identified in dependence with the size of load. Calculations were made on possible effectivnes with regard to size of load, harvesting and transportation distance. Calculations of economics of forestry trailer in combination with tractor used in field measurements were made, forestry trailer with tractor was compared with truck transportation and comparison amongst the tractor and truck transportation is identified.
