Ergonomics in CTL harvesting - assisting systems and future visions

Abstract

The cut-to-length (CTL) timber harvesting method, prevalent in Northern Europe, requires well-trained professional staff and ergonomic, efficient machinery. This study investigated operators' perspectives on ergonomics in CTL harvester work, focusing on the current use of assisting systems and the future visions of machine development. Interviews were conducted by phone with 20 CTL harvester machine operators. The interview method was a modified version of the traditional contextual interview design, allowing operators to work concurrently. The semi-structured interview framework consisted of two sections, the first part focused on the current harvesting system, while the second addressed operators' perceptions of future advancements and ratings of future machine development visions. Results revealed that the most mature assisting systems were well utilized and functional, while newer systems' utilization, usability, and function had more variation. Decision support tools, such as map layers, even when seldom used, were welcomed and instilled confidence in decision-making. Operators appreciated machinery and systems that reduce cognitive and physical strain, and they look forward to future advancements, such as technology that aids in assessing log quality. While independent work benefits from the operator's motivation, a supportive work culture and high-quality management are crucial for promoting work expertise and the comprehensive utilization of machinery.
