Description

Tower crane auxiliary system and its control method The present invention relates to a tower crane assist system and a method for controlling the same. Recently, labor productivity in the construction industry has continuously declined and remained sluggish compared to other industries. The reason for this sluggishness can be found in the unique characteristics of the construction sector that distinguish it from other industries. Specifically, the construction industry is excessively site-oriented and labor-intensive compared to other sectors. In particular, productivity at most construction sites is inevitably lower compared to other industries because materials are processed and assembled on-site. Furthermore, while other industries continuously introduce new technologies to increase productivity, the construction industry faces difficulties in adopting new technologies because production activities are carried out through direct on-site work by laborers. Therefore, it is necessary to utilize specific programs to leverage technologies directly linked to the productivity of the construction industry, thereby transforming its site-centric nature into a factory-centric one and its labor-centric nature into a technology-centric one. Regarding the necessity of such changes, the Off-Site Construction (OSC) method can be utilized. OSC refers to a factory production-on-site assembly method where building structures, interior and exterior materials, and interiors are manufactured in an off-site factory, transported to the site, and assembled. OSC components refer to the parts used in the OSC method. Through this, each building component can be standardized and modularized, thereby increasing production efficiency and shortening the construction period. However, this OSC method is merely utilized for assembling factory-produced materials on-site, and the reality is that it still has not been able to break away from a labor-centered approach. In other words, it was necessary to incorporate and utilize new technologies that could shift from a labor-centered to a technology-centered approach by utilizing the OSC method.
