Abstract

The objective of this study was to evaluate the performance and determine the costs of two cable yarder systems in the extraction of eucalyptus wood in mountainous regions. The technical analysis was based on the study of times and motions of the operating cycle and productivity of two extraction systems: System 1 (tractor Massey Ferguson 297 and winch Penzsaur K301-T) and System 2 (excavator Caterpillar 320L and winch Koller), operating in plantations aged seven years old and of second rotation. Average productivity in logging was 13.63 m3 h-1 for System 1 and 14.70 m3 h-1 for System 2 for a distance of 150 m on average, operating efficiency of 46% and 51% and mechanical availability of 91% and 59%, respectively. The increased extraction distance resulted in increased time to perform the activities of the operating cycle and reduced productivity. System 2 was more productive, but showed higher production costs.
