Abstract
As the scale of construction projects increases with taller buildings, efficient use of tower cranes has become much more important to the successful completion of projects. Over the past decade, the mechanical performance of tower cranes has improved dramatically and contributed greatly to the improvement in construction efficiency of social infrastructure and larger high-rise buildings.

A tower crane is one of the major machines used in the construction of high-rise buildings. However, the operator does not receive adequate information such as the target space condition and lifting material to control the crane , and this degrades work productivity and safety.

This study proposes a prototype of the advanced tower crane (ATC) equipped with wireless video control and radio frequency identification (RFID) technology. To do these, the following sections describe the main scope of this research: (1) reviews recent trends in component technologies and their probability of application to the development of a new tower crane operating system and defines a wireless control video module and a radio frequency identification (RFID) application module for the new system (2) describes a framework for information technology (IT)-based advanced tower cranes and (3) develops a prototype of a tower crane operating system that can improve communication efficiency between workers in the stockyard and crane operators using wireless video camera. Finally, future challenges are discussed.

With these advanced technologies, the ATC can provide the crane operator with an enhanced view of the work space and various functions to track up-to-date material status. It can also provide faster flow of information with greater accuracy and improve the driving efficiency of the equipment. The ATC was applied to a pilot construction site for case study to test its performance. The result confirmed considerable improvement in operational speed and significantly enhanced performance in work safety and communication efficiency.

However, commercialization of the system is still far off, because the system has some constraints that hinder improvements in system efficiency.
