Abstract

This chapter investigates the reliability measures of an elevator system under the study of different failures. The considered system consists of car which is loaded with steel cables and attached by guide rails for up and down motion, and these steel cables are further attached by the pulley and gearbox system on the top of the building or on the uppermost section of the unit. The elevator faults affect not only the operations of other assets but may also result in injuries or even death. So, governor and breaks are also fitted to have a control over speed and sudden failure. Steel cables are also used in a large number to prevent the accident due to cable failure or complete fracture. The authors also analyze the expected profit in the system after the examination of maintenance cost. They are employing the coverage factor technique to enhance the lifetime of the system along with the birth-death stochastic model of elevator and have also taken some numerical examples of the real impact of these measures. The results of the proposed model offer an effective technique for elevator maintenance. Finally, the authors demonstrate the behavior of each parameter graphically.
