Tractor overturn is the main cause of injuries and fatal accidents in agriculture. Rollover Protective Structures (ROPS) showed to be effective in reducing fatalities during tractor overturn. Foldable ROPS (FROPS) have been developed to offer greater mobility when working in low overhead clearance zones and more storage options. However, many fatalities and serious injuries in tractor overturn accidents occur for a misuse of the FROPS. The study proposed a multidimensional ergonomic investigation of FROPS handling to identify criticalities in the human-machine interaction which prevent farmers from raising the roll-bar. An observation of users’ behaviors while operating the FROPS and a collection of subjective ratings about perceived effort were performed, considering also tractor objective features. Eleven operators and nine tractors were involved in the study.

The vertical distance between the FROPS pivot pin and the ground affected participants’ gestures and postures. To facilitate the actual use of the FROPS and to prevent injuries or fatal consequences in case of tractor overturn, some technical solutions to enhance the accessibility of the FROPS may be developed.

Abstract

Tractor overturn is the main cause of injuries and fatal accidents in agriculture. Rollover Protective Structures (ROPS) showed to be effective in reducing fatalities during tractor overturn. Foldable ROPS (FROPS) have been developed to offer greater mobility when working in low overhead clearance zones and more storage options. However, many fatalities and serious injuries in tractor overturn accidents occur for a misuse of the FROPS. The study proposed a multidimensional ergonomic investigation of FROPS handling to identify criticalities in the human-machine interaction which prevent farmers from raising the roll-bar. An observation of users’ behaviors while operating the FROPS and a collection of subjective ratings about perceived effort were performed, considering also tractor objective features. Eleven operators and nine tractors were involved in the study. The results showed that the participants exposed themselves to different safety (e.g. falls) and health (e.g. biomechanical overload of the spine) risks when raising the FROPS, even though they did not perceive any intense effort in handling the roll-bar. The vertical distance between the FROPS pivot pin and the ground affected participants’ gestures and postures. To facilitate the actual use of the FROPS and to prevent injuries or fatal consequences in case of tractor overturn, some technical solutions to enhance the accessibility of the FROPS may be developed. Furthermore, the correct postures and gestures to handle the roll-bar should be addressed during safety and health training courses.
