Research on the safety HME-CM approach of cranes in their service life cycle

Crane is one of the vital components and lifelines of the construction industry. However, crane accidents happen regularly due to a variety of factors. Among them, the most far-reaching influence is the three factors of the human-machine-environment (HME). Moreover, how to carry out safety management for them is very critical. Considering the barriers to the goal, this study applied configuration management (CM) to HME data change management in cranes’ service life cycle and proposed a HME-CM framework and approach. First, based on the original CM theory, baselines were developed to accommodate changes in HME configuration. Second, we discussed the evolving trajectory of HME configuration and determined the content and updates to the baseline. Third, a marking method based on data provenance theory was proposed to achieve data consistency. Finally, two search procedures were designed to perform the tracking and tracing of HME configuration. This paper contributes to expanding the application of CM theory in crane safety management, ensures the controllability and traceability of crane configuration changes, and provides a new perspective on crane safety.
