A New-Structured Tower Crane

Abstract:

Advantages and disadvantages of present tower crane's upper structures are analyzed in this paper. According to the theory of prestressing jib, through combination design, a kind of structure is presented which can realize multiple use and greatly improve the hoisting capacity. Mechanical analysis and contrasts are done for old and new designs by finite element analysis software ALGOR. Finally, an example is given to verify the validity and feasibility of the design
