Abstract

Motorji z notranjim izgorevanjem v motornih žagah imajo vrsto nezaželenih lastnosti, so neučinkoviti in vir negativnih vplivov na zdravje delavca zaradi izpustov ogljikovega monoksida in vpliva vibracij ter ropota. Šele s pojavom baterijskih motornih žag, ki zaradi uporabe baterij ne potrebujejo direktnega priklopa v električno omrežje, lahko začnemo razmišljati o uporabi takšnih žag tudi v gozdarstvu. Ker smo želeli preizkusiti uporabnost takšnih žag, smo izvedli poskus, pri katerem smo primerjali tri baterijske žage z bencinsko žago. V tridnevnem poskusu smo izdelali 28,43 m3 okroglega smrekovega lesa. Ugotovili smo, da je bil povprečni učinek dela pri baterijskih žagah 2,18 m3/h, pri bencinskih pa 6,34 m3/h, in dokazali, da je učinek bencinske žage značilno večji od učinka baterijskih žag. Baterijske žage so učinkovitejše le pri sortimentih, s premeri manjšimi od 15 cm.

Secondary title:	Work efficiency nd power consumption of battery chainsaws
Secondary abstract:	Internal combustion engines used in chainsaws have many unwanted influences, mainly environment pollution with exhaust gases and detrimental effects on the worker's health due to effects of vibrations, noise and carbon monoxide inhalation. With the appearance of cordless electric chainsaws, which do not require a wired connection to the electrical network, it is possible to use chainsaws with an electric motor in forestry as well. To test these chainsaws in real-life forest conditions three different cordless chainsaws were compared to a gas-powered chainsaw. In three days of work 28,43 m3 of round spruce wood were produced. The average work performance of battery-powered chainsaw was 2,18 m3 /h, while gas-powered chainsaw produced 6,34 m3/h. It was demonstrated that the effect of the gas-powered chainsaw was significantly greater than that of a battery saw, however, the battery-powered saws are more effective for tree diameters lower than 15 cm.
