A rapid lift study generation system for heavy industrial projects Ofrim, Brian D.; Lei, Zhen; Hasan, Tarequl; Al-Hussein, Mohamed; Bouferguene, Ahmed


The process of creating mobile crane lift studies for heavy industrial projects can be time-consuming and tedious. A large portion of the lift studies required for such projects involve modules that are prefabricated and transported to the site. Composing these lift studies currently requires a considerable amount of time and manual work. Due to the complex nature of these projects the lift studies also often require significant revisions to accommodate changes to the initial plans. This paper introduces a rapid lift study generation program to assist in the planning stage by expediting the drafting process. The program utilizes Autodesk’s AutoCAD, which is one of the most widely used drafting software applications in North America. A custom plug-in to AutoCAD written in the Visual Basic programming language is used to create the graphic portion of the lift study. A separate Windows Form application is used to produce a table of the crane and lift information, such as lifting capacity, ground bearing pressure calculations, and mat design. This application is supported by a database of specifications for various crawler cranes and configurations as well as capacity information. The application allows the user to input information such as the module’s weight, rigging weight, and lift radius in order to obtain a table of relevant information for each lift. This rapid lift study generation program has been tested for validation on a heavy industrial project for which the lift studies had already been prepared by NCSG Crane & Heavy Haul Services using the traditional method.
