Through the investigation and study of the restructuring team and the experience gained through reference to the reform of Brotherhood Bureau, according to the particularity of this platform requirement, the use time is short and the utilization rate is low at ordinary times. If mechanical automation or the flatbed conversion is used, the custody, maintenance, Manufacturing and so there are some problems, and finally we have adopted in the fifty-one and sixty-three based on the innovative program designed to disassemble the end of the steel platform (Figure 1), reached a platform body light, structure
