Mechanical properties of elevator ropes and belts exposed to corrosion and elevated temperatures

Abstract

Abstract Safety in elevators is extremely important phenomenon. Elevator accidents occurring today are at a level that seriously threatens the safety of life and property, and especially elevator ropes and belts have a very important place in these systems in order not to endanger human life. As with every mechanism, stress, fatigue and deformations occur in elevator parts and equipments such as ropes and belts over time causing impairment and reduce their strength. In this study, artificial defects were given to the 8 × 19 Warrington steel wire rope and polyurethane coated elevator belt to examine the effects of different type of corrosion and elevated temperature deterioration on mechanical properties and their comparisons were made. Results indicate that the percent reduction in lifting capacity of the elevator belt investigated was lower than that of the 8 × 19 Warrington rope in all degradation types examined.
