Since Illegal activities such as illegal modification and falsification of the specifications of tower cranes indicating false year become more sophisticated and the procurement of low-quality and cheap equipment has been an industrial practice, concerns about safety accidents of tower cranes are increasing day by day.
However, the current Act does not specify a production standard that can be used for the safety of tower cranes and, moreover, cannot impose any sanction to a person who poorly produces the construction machinery of famous foreign producers by making imitations in China and subsequently exporting them to Korea.
Accordingly, in addition to falsification of specifications, it is a reality that the illegal acts are common, such as unlawfully modifying manned tower cranes to unmanned tower cranes in sites, illegally lifting weights of three tons and more after registering construction machinery as small-sized ones with the lifting weight of less than three tons, or safety accidents including bowing and breaking of equipment even in case of lifting the weight that does not exceed the specified weight. Related organizations and industries pointed out these problems and are demanding that measures to eradicate illegal acts such as indiscriminate importation of poor-quality equipment or illegal modification be taken quickly.
Therefore, this amendment aims to prevent illegal activities and prevent safety accidents caused by tower cranes by requiring that tower cranes shall be produced in pursuant to Korean Standards and making it mandatory that an operator’s cab be installed for tower cranes that rotate at high altitude (Article 12).
