Abstract

Abstract

The objective of this study was to evaluate the time consumed by the elements of the work cycle and the productivity of a chocker skidder in extraction of wood at different slope terrain and distances classes, generating information for efficient planning of operations and better utilization of available resources. The study was conducted in a forestry company located in the municipality of Itararé, São Paulo State. A motion and time study of the operational cycle was performed, determining the mechanical availability, technical availability, operational efficiency and productivity of the machine in different conditions of extraction distance and terrain slope. The results showed that elements of the work cycle which most time consuming were the "drag cable and engagement" and "disengagement of the currents" that consumed the greatest operational cycle of the machine with 28% and 11% of the total time, respectively. A reduction machine productivity with increasing of the terrain slope, being stronger in the smaller extraction distances and, showing the sensitivity of this variable in this operating condition.
