3D Visualization-Based Motion Planning of Mobile Crane Operations in Heavy Industrial Projects

摘要

The successful completion of modular-based heavy industrial construction projects relies heavily on safe and efficient crane operations, which have a direct impact on project productivity. Corresponding to the design of reliable crane operations, this paper proposes three-dimensional (3D) visualization-based motion planning for mobile cranes that integrates 3D visualization with mathematical algorithms based on "what if" scenarios. This method facilitates the design of collision-free mobile crane operations for a large number of lifts in congested areas. The proposed methodology is established based on two types of interactive analyses: (1) rotation analysis to build 3D visualization for the motions of crane body configurations; and (2) spatial analysis to detect potential collision errors in order to design collision-free crane operations. The rotation analysis accounts for calculating the angles describing the orientations of mechanical elements in the crane system by reading the coordinates of the crane location and the pick and set points of the object (module) to be lifted. The spatial analysis is used to monitor and maintain sufficient clearances between existing obstacles and the crane body configurations in order to prevent potential collisions during crane operation design. The methodology is tested on a case study in order to illustrate its effectiveness. (C) 2014 American Society of Civil Engineers.
