Movement analysis of a worker in the forest cleaning activities

The main tool used in a forest cleaning is a billhook, a hand tool consisting of a hold and a hooked blade sharpened on both sides. Forest cleaning is physically very tiring and takes place under difficult working conditions (high temperature and humidity, dense vegetation, insects). Moreover, working with billhook is exclusively manual work and its effects on health are mostly unknown. A novelty in Croatia, regarding motor - manual forest cleaning, are battery shears, a more ergonomic and humane approach to forest cleaning. For the purpose of the ergonomic comparison of the two types of forest cleaning methods, a top technology was used – Xsens MVN. Xsens technology consists of sophisticated hardware and software for human movement analysis. It is a full-body human measurement system based on inertial sensors, biomechanical models, and sensor fusion algorithms. The aim of this paper is to present a new and modern method of movement analysis in ongoing research of two mentioned forest cleaning methods, to show challenges of field measurements, and to assume possible application in forestry regarding ergonomic measurements.
