A. Appendix Factor=0.55 for Guide rail's deflections base on the following A.1 Expression & Factor for Guide Rail's deflection The Expression for Elevator Guide Rail's deflection is as follow If above expression is compared with the below expression for deflection of simple beam, we know that 0.7 factor is given Therefore, the Elevator Guide rail's deflection is 0.7 times than deflection of simple beam. 0.7 times realize the deflection. A.2 The distribution of deflection for each location factor of car rail The distribution of deflection for each location factor of car rail is as follow. As based on the above picture, the deflection factor for guide rail of each position is various, the maximum factor on the end of rail is 0.7, and the factor on the middle rail is 0.55 As based on this, the two deflections for guide rail are 1) The Expression for the end of Guide Rail 2) The Expression for the middle of Guide Rail To meet 1) and 2), In OTIS, the pitch of the rail bracket on the end of rail is applied to 1000~2124, and it on the middle is applied to 2500, So. It can be no problem for the rail deflection's strength In conclusion, if the end of Guide Rail's deflection is compared with the middle, the following expression is derived The above expression shows if the pitch of the rail bracket on the end of rail is applied to 2124 and it's on middle is applied to 2500, it can be calculated with factor=0.55, Pitch=2500
