Abstract

As the tower crane accident emerged as a social issue in 2017, various government measures were prepared. Most of the measures are focused on erecting, climbing, and dismantling phases. Analyzes of 84 serious accidents related to tower cranes from 2000 to 2018 and 104 near misses accidents from 2016 to 2018 revealed that 50% of the serious accidents occurred during the operating phase. The main occupation influencing operating phase accidents was signalman(81.6% of serious accidents), whose communication and competency were governing causes. This result was the same in 294 questionnaires to signalmen. Signal systems and education policies for tower crane signalman in Korea and foreign countries were analyzed, and standardization of wireless signal system and improvement of education system were propose.
