This paper introduced the integrated optic mechanical and electronic designing scheme for large radio telescopes.The scanning motion track of linear feedback was deduced according to the geographical position of landforms of Guizhou KARST area.The method of solution for cable's deflection and tension were obtained from linear equation of suspension chain.The kinematics description and analysis were carried out upon structures of six suspension cabled parallel cable system.The solving means of real time problems for controlling the lengths of cable were advanced.Finally the formulae of cable tip coordinates in dynamic test have been given out.
