Comparison of the Performance of Individual Wood Logging Methods
Pudlo, Pavel ; Macků, Jan (advisor) ; Štícha, Václav (referee)
The aim of the bachelor thesis was to perform literary research on the topic of the productivity of individual wood logging methods for forest cover and verify this productivity by comparison of the time dimensions either by using the harvester or working with the woodcutters. The main contribution of the thesis research results are own measurement. Measuring of the productivity of individual wood logging methods was carried out in the conditions given by the method cut to length by salvage cutting, that launched because of hit by bark beetle or strong wind. The measurement was carried out on five stands with harvester and on two stands with woodcutters. It was a measure of one harvester operator and four woodcutters. The measurement was done with the help of cameras that caught the working times of woodcutters and the harvester. The resulting times, due to the productivity and stem volume of the trees, recorded times by harvester were better and for that reason that method had proven to be more effective. In one of the monitored stands the effectiveness has not been demonstrated, because the operator has not logged in this forest cover enough m3 of the wood and the work was, therefore, loss making and time consuming. By the work of the woodcutters has the efficiency and shorter working times showed in two stands, where the measurement was carried out. Their productivity has been effective there, for example, with regard to the low number of trees and the larger crop density, the harvester technology would not be efficient.
