An Overview of the Tower Cranes and their Safety in Construction Operations
Subject Areas :
Keywords: Tower crane, Mobile crane, Technical specifications of tower cranes, Factors affecting site safety,
Abstract :
Cranes in construction sites are vital for modern building projects, enabling the lift and move of heavy materials with precision. However, their operation involves significant risks, making safety and adherence to standards crucial. Proper crane setup, regular inspections, safety management level of the site and/or the contractor company, and certified personnel and operators are essential to prevent accidents. Overloading, unstable ground or mechanical failures can lead to accidents and endanger workers and pedestrians. Therefore, implementing national standard regulations ensures structural integrity and safe operation. In this research, after a classification of the tower cranes, some technical notifications are presented. Moreover, we discuss a relatively novel categorization method for measuring the importance(weight) of each factor affecting safety in construction sites with tower cranes quantitively. This can be used to measure the total safety level of such sites.
