Individual Elevator Performance

Over the past decade, global awareness of elevator performance has heightened. Higher rise applications in Europe, in Asia, in the mid East… have necessitated consideration of performance potential of planned elevator groupings. Each company and each consultant concerned with suitable elevatoring, have developed standards for evaluating service, and systems for calculating or simulating such potential during project planning. At the same time pressures have developed for improvement in ride quality and door operation and enhanced safety, while concern for disabled access, especially in the U.S., has resulted in regulations adversely affecting individual car performance. This paper reviews the theoretical effect that changes in individual elevator operating characteristics can have on elevator performance, specific areas studied are speed, acceleration, jerk, door opening time, door closing time, door type, and, door hold open time.
