| Abstract |
In general, monthly rental cost of tower crane is expensive and accidents related to material lifting, handling and distribution in construction sites sometimes bring severe losses to the project participants in both time and cost. Recently, material lifting, handling and distribution using tower cranes in especially high-rise building construction sites have received considerable attention by site managers in an effort to ensure efficient material supply and reduce safety concerns. During the last few years, a number of research efforts for improving the work efficiency of tower crane have been conducted, using a wide variety of automation and sensing technologies. However, the results of such research efforts have not effectively used in construction sites because of the lack of site adaptation. The primary objective of this study is to propose a new approach to enhance the work efficiency and minimize the safety concerns related to the operation of tower crane. Global Positioning System (GPS) and machine vision techniques are utilized in order to achieve such enhancements. A conceptual design of the semi-automated tower crane and entire work process using the conceptual design are illustrated in this paper as well. |
