Development of Prevention System from Hitting for Hydraulic Excavators

Fatalities caused by industrial accidents in the construction industry have remained level since the first half of the 1980s. The majority of these fatalities are caused by falls, contact between workers and construction equipment, or by overturning construction equipment. This project was undertaken to study the hitting between workers and construction equipment, and develop technology to improve the safety of construction equipment etc. in order to prevent accidents in the construction industry. Specifically, new hitting prevention technology has been developed by proposing and studying a detection system consisting of ultrasonic sensors (transponder mode) as a new technology to prevent hitting between workers and construction machinery, and by conducting performance tests and studies of its applicability to actual construction sites to confirm its safety and usability.
