Abstract By people known as the”Giant of the arm”,”draw the art in the sky”,”a symble of strength and beauty” ,of the crane is widely used in material production sectors of the national economy and the importance of loading and unloading 。Crane is that in a certain range of multiple motion vertical lifting and horizontal lifting hoisting machinery. Also called crane. Belonging to material handling machinery. Crane's work is characterized by intermittent exercise to do, namely, the corresponding mechanism of material in a working cycle of migration, the unloading action of the alternate work.
This design is the mechanical design of slewing hydraulic crane, the crane to meet the new requirements of classification society, mainly for daily necessities and ship lifting equipment. Firstly, according to the main technical parameters are given by using SolidWorks to draw the 3D map of each part, and then make the assembly drawing; then, design and calculation of the general parts according to the main technical parameters given: Calculation of the boom design, stability calculation of boom boom, calculation of bearing design, shaft design calculation of hydraulic cylinder support, calculation the rotating part design, calculation of the hydraulic pump station design. Finally the calculation results into design specifications.
Keywords: Rotary hydraulic crane; mechanical design; solidworks
