Tiivistelmä
The researches of mechanized bamboo felling do not exist and only available studies deal with manual felling. The objective of this thesis is to help identifying appropriate harvesting technologies for intended commercial scale bamboo fuel chip production, where raw material procurement is done in unmanaged stand. It does not provide final answer, but can be classified as the beginning of a larger whole.
The objective was achieved by conducting time and motion studies with several different supply chain elements in the pilot site area in northern Lao PDR. Obtained productivity figures were incorporated with machine cost calculations and thereafter unit costs per each element were determined.
The results presents that conventional manual harvesting method is inefficient in terms of productivity, but due to low labor cost, it is relatively competitive in terms of unit costs.
Due to low labor cost, the essential requirement for appropriate harvesting technology is high productivity rate. Felling with assistance of tractor winch was the most viable alternative in terms of by both, productivity and unit costs. The results were obtained with a workforce who had no work experience on mechanized forest work.
