Jämförande tidsstudie vid riskörning med kompakteringsskotare och traditionell ?lätt? modifierad skotare
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU.
The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder.
Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3. Higher annual production and a lower cost for the ordinary forwarder makes it hard to justify an investment in a forwarder with a special compression device.
