Article Preview

Abstract:

Combined with the engineering project of a bridge in Lanzhou, the derrick crane girder method in the special terrain conditions of the construction technology and process is introduced in detail, also the internal force of steel wire rope is calculated in detail. After applying in practical engineering, it proves that derrick crane lifting method is not only safe and reliable but also economical and feasible.
