PENNA, Eduardo Silva et al. Ergonomic evaluation of skyline models used in forest extraction. Rev. Árvore [online]. 2011, vol.35, n.3, pp. 565-571. ISSN 0100-6762.  http://dx.doi.org/10.1590/S0100-67622011000300019.

This study was conducted in a forest company, located in the municipality of Cerro Azul, PR. The objective of this study was the ergonomics evaluation of using three skyline models, K301, K501 and K601 used in the extraction of full Pinus spp. trees in mountainous regions. It was used a questionary answered by the operators of three existing towers, evaluating the following variables: access to cabinet work, working position of the operator, operator seat, controls and instrumentation, climate in the cabin, the cockpit visibility to the field, exhaust fumes and dust, and vibration. The models K301 and K501 models do not meet the ergonomic requirements, therefore their operators are susceptible to risks in their working hours, whereas the model K601 has satisfactory ergonomic conditions.
