HIGHLIGHTS
- Experimental instrumentation have been conducted on the elevator guide rail bracket.
- Elevator investigated was subjected to a full load braking test.
- Normal stress variation during braking process were measured by using strain gages.
- The most critical loading type is found as loading of three fourth of cabin at front.
- The maximum equivalent stress increased by 8.44% when the cabin was loaded at front compared to right-side loading .

TOPICS
ABSTRACT
The rapidly increasing world population, high urbanization rates of countries and shrinking living spaces have forced people to live in multi-storey buildings. Guide rails and guide rail brackets are used to connect guide rails to the wall of elevator shaft. In this study, behaviour of guide rail and rail brackets against free fall of a passenger elevator is investigated by taking into account different loading and operating combinations considering related standards. Elevator guide rail and its bracket are computer aided modelled and finite element analyses are performed. In addition, experimental instrumentation and measurements have been conducted on the elevator guide rail bracket so that emergency braking reliability of elevator guide rail components can be evaluated when the elevator is loaded with 125% of its maximum capacity and the cabin goes into free fall due to reasons such as rope breakage. It can be concluded from the findings that dynamic effects during the running and braking of the elevator have an effect of 20% compared to the results of the static analysis.
