The thesis deals with the structure of times in cable harvesting with the Konrad Mounty 4000 cable crane. The daily productivity were measured at different skidding distances, separately for uphill/downhill harvesting. Heart rate measurements during work determined whether the difficulty of the chokkerman's work changes with increasing skidding distance. 257 useful cycles of wood skidding were recorded at four worksites. The chronometric method of time measurement was used. Based on the measurements, the proportions of productive and non-productive times were calculated. A comparison of the productivity of the cable crane according to the worksites was carried out. The measured daily productivity were compared with the productivity determined by standard times for the Syncrofalke 3t cable crane. We analyzed the dependence of the wood skidding distance with the measured heart rate. Comparisons of the measured average pulse with respect to work operations on different lengths of cable lines were illustrated by graphs. The results of the measurements show us higher daily productivity for a 4-ton cable crane than the normal productivity for a 3-ton cable crane. That data confirms one of the hypotheses in the thesis. With the thesis, it was established that the productivity of harvesting wood uphill are higher than downhill, and that the difficulty of the work of the chokerman decreases as the skidding distance increases.
