Klaus Feyrer was a gifted designer full of vigour to deal with lift construction topics. Among other things he was extremely interested in the dynamic problems of braking operations and in probability theories in connection with the failure of safety components. His rope service life calculation method is the basis for the determination of the safety factor of suspension means in the lift standard DIN EN81.
