| Summary: | The paper presents the results of research into the efficiency of work of the
Konrad Mounty 4000 mobile forest cable yarder with a processor head in the
transport of wood assortments in beech stands. The research was conducted
through a time and work study. The research was conducted in the Ribnik
Forestry and Economic Area, more precisely in the “Ribnik” Forestry Estate.
The effects of the operation of the mobile cable yarder differed depending
on the operating conditions, the length of the cable route, the lateral
distance of attraction, the average volume of the tour, the construction
method. The effects of working with a mobile cable yarder with a processor
head were determined individually by phase. Norms for cutting and making
tree parts depending on the diameter of the tree at chest height. It was
found that the speed of movement of the carriage along the mainline, as well
as the speed of movement of the load to the mainline decreases with the
increase in the volume of the load. The time of pulling the rope and pulling
depends on the distance of the pull and the slope of the terrain. With the
increase of the transport distance and the average slope of the terrain when
pulling the rope uphill, the pulling time increases. Based on the results of
the research, it can be concluded that the mobile forest cable car with a
harvester head, which was the subject of the research, represents an
alternative technical solution when it comes to the first phase of
transporting wood assortments in pure beech stands of poor quality. |
