Allan Smith method is designed to the specific requirement of the slow speed rotary machines. This method is designed to align two pier-supported system only. This is to mechanically stabilize the two pier supported equipments. This method has been designed after studying number of pre-alignment and post alignment problems on 2 pier supported equipments. This is the complete alignment system. In Floating point alignment method, we endeavors to bring all the four floating point on a reference plane to achieve uniform load sharing by the support rollers.
