Abstract: Abstract: With the development of today’s modern mine construction, large box-shaped steel derrick is widely used. In order to realize the combination of the derrick assembly technology and the modern mine construction, in order to obtain the improvement of the large box-shaped derrick assembly technology and safety technology, also to speed up the construction period of the box-shaped derrick, reduce the cost and the labor intensity, which can make the assembly meet the safety demand and rationality requirements. This paper introduces that our company has adopted this technology of the box crane derrick construction successfully, which is mature, safe and reliable. Not only is this technology in good quality, but it also is in a economical price. It is hoped to help to promote the technology of box-shaped derrick assembly and the construction of box crane derrick.
