Abstract:The construction industry is an important part of the national economy in China, there are more difficulties due to the increasing scale of engineering projects, especially the security problems, which always trouble the construction enterprises. High-rise buildings have mushroomed appear constantly, the use of tower e more frequently, it has became the monly used construction equipment of the vertical transportation. However, crane is the major risk project of construction, how to ensure the crane can work reliably is the important technical problem. At the same time, in order to achieve the goal of construction safety and reasonable to reduce the security input as far as possible, it ply with the principle of safety benefit to ensure economy. This paper will be based on security benefits of crane safety input, and search for the best security investment point.
Key words:security benefits; crane reliability; security investment point
