![]() ![]() The results are also compared with the previously developed lift planning algorithms, showing a remarkable reduction in the project’s total cost. ![]() ![]() The suggested framework is validated successfully in an actual modular construction project in Alberta, Canada. This study contributes to the body of knowledge by proposing an enhanced graph-based optimization algorithm for multiple concurrent heavy lift operations. Dijkstra’s search algorithm is utilized in the current study to select each module’s optimum lift option. This paper introduces an integrated framework to automatically generate an optimum lift plan based on a predetermined lifting sequence. Despite numerous efforts in this area, there is still room for improvement to enhance the optimality of solutions, which leads to considerable cost reduction. However, choosing among a large number of available lift options (e.g., types, configurations, and locations of cranes) to develop multilift plans can be challenging. An optimized lift plan is essential for multiple lifts due to high rental cost of heavy lift cranes. The latest additions include Liebherr LTF 1035-3.1, Liebherr LTR 1100, Tadano ATF 130G-5, and Maeda LC 755-3.Planning lift activities of mobile cranes for a modular project can raise productivity and improve safety. In addition, cranes can be added upon request by KranXpert. In addition, installation of the program is not necessary, as the download is directly executable.Ĭrane models are continually being added to the program or can be added by the user with the free crane editor. It requires Windows 2000, XP, or Vista operating systems. The latest free edition was introduced in 2010. All previously created plans can be opened in the new version and viewed in 3D by simply clicking the 3D tab. , and a user of the KranXpert program: “The 3D version improves the orientation of complex plans with multiple objects while retaining the ease of use and intuitive interface that were hallmarks of the 2.5D program.”ĭeveloper Markus Scholl has left the familiar drawing tools from the older version of the software in place which means there is almost no learning curve for users moving to the 3-D version. KranXpert Free-Edition 2010 is a free available crane job planning software with different views like the full kranXpert version. According to Michael Harrison of Harrison Crane Service, Miami, Fla. March 18, 2011- KranXpert, a lift planning software available in both free and full versions, recently introduced 3D modeling. ![]()
