Planning heavy lifts is a complex process. The conventional tools available for planning are limited. As a result, the planning process is tedious and cumbersome. This work focuses on developing a heavy lift planning tool within the AutoCAD environment. The planning features of the tool are developed within two key modules: the Visualization. Module and the Database module. The visualization module is implemented using AutoLISP and incorporates features for viewing and manipulating the spatial attributes of the plan. The Database module is implemented using Visual C++ and Microsoft Access. This module updates the lifting capacity of the crane based on the selected configuration, boom length and lift radius. The implemented lift planning functions were tested successfully using a case study. © 2004 ASCE.
