Today, construction sites are rapidly becoming larger, taller, and more complex, along with the advancement of advanced technology.
While these changes have increased productivity and efficiency, they have also significantly increased the risk of safety accidents.
In particular, construction machinery such as tower cranes, construction lifts, mobile cranes, pile drivers, forklifts, and aerial work platforms are essential equipment on site, so their incorrect use, insufficient inspection, and failure to follow safety rules go beyond simple work delays and directly lead to casualties and social losses.

To prevent these risks, this book comprehensively covers the structure and characteristics of construction machinery, inspection points, installation and dismantling procedures, key safety devices, relevant laws and regulations, and actual accident cases and lessons learned.
This is a practical guide that comprehensively organizes practical knowledge that can be applied immediately in the field, rather than a simple equipment manual.

Safety is never a formality.
Safety education is an absolute value directly related to life, not just a 'duty'. One person's carelessness can cause serious damage to colleagues, the organization, and even society as a whole.
Therefore, we must view safety as an investment, not a cost, and we must not forget that prevention-focused safety management is the key to sustainable development in construction sites.
I hope this book will serve as a small stepping stone toward spreading the awareness that "safety equals competitiveness" throughout construction sites.
