According to the parison we choice the single pillar stacker , In the design of the mechanism ,we according to he motor institutions determine the general structure of a stacker crane, Then cording the resistance to calculation traveling motor power and determine the motor model. Tracking the movement double column type orbit. Structure is simple and good in usability. The goods for the expansion institutions fork drawer the principle of orbit. According to the design requirements of the main ponents of preliminary selection, then to parts of checking intensity. to ensure that the choice of rationality . In the last part of this paper , the stacker strength and stability for a more detailed analysis , so as to ensure the smoothness of work stacker slide may run and reliability .
