Anthropometrics Parameters of the Adult Population as Ergonomics Modifier for the Chainsaw Handle

Abstract

In the conditions of Slovakia, forest harvesting is largely carried out by hand-held chainsaws. Working with a chainsaw is one of the most demanding tasks in forestry, both in terms of demands on the operator and compliance with technological and work discipline. The aim of this work is the analysis of selected anthropometric dimensions of the upper limbs of the adult male population and their comparison with parameters and approaches in the design of hand-held controls for manual chainsaws. The research was conducted on a sample of 1629 men aged 18 to 25, in whom six anthropometric dimensions related to the upper limbs were measured, which are important for the sizing of the controls on the chainsaw handles. The results of the anthropometric analysis were compared with the recommended values for the design of hand-held chainsaws. Based on the results obtained, we identified some parameters of the front and rear handles that would need to be resized. Most of the recommended dimensions are in a convenient range. However, to take into account user comfort, we suggest, in some cases, increasing their minimum recommended values.
