Abstract

In order to ensure safety and efficiency of lifting operation and reduce risks of its spatial conflicts, Manhattan plane of lifting operation was designed. Then, OARMST model of lifting trajectory was constructed by analyzing spatial conflict factors, mechanical operation conditions and construction organization conditions. Finally, lifting trajectory planning system was developed to explore safe moving trace of lifting objects under multiple sites and obstacles by integrating Dijkstra heuristic algorithm and ultra wide band (UWB) positioning technology. The research shows that the optimal moving trace obtained from OARMST model can avoid spatial conflicts, prevent multiple sudden suspensions of hanging objects and redundant operation of drivers by reducing turns and displacement of objects, therefore improving safe dispatching of lifting operation. © 2020 China Safety Science Journal.
