Elevators, escalators, and moving walkways are key equipment that facilitates the movement of large numbers of people for public transit, airports, theme parks, large buildings, and other venues. Without such equipment, people traffic and the related business operations are significantly slowed.

An example of the critical role that conveyance equipment plays in the operation of these types of facilities is the London Underground, where the famous Tube transports over 1.1 billion passengers per year. The conveyance equipment used by the London Underground includes 426 escalators (one with a 90 foot vertical rise) and 164 lifts, or elevators. This equipment runs 20 hours a day and is able to handle over 13,000 passengers per hour. With that kind of volume and traffic, extremely high reliability of the conveyance equipment is a requirement.

Relying on complaints from the pubic to notify management of an outage in conveyance equipment will not result in high reliability of the systems. Achieving high reliability requires the equipment to be monitored and managed in real time. Such monitoring can provide facility management with the current status of the equipment, as well as the capability to analyze

data to discover and predict its performance, use, and the need for maintenance

Figure 8.1 data to discover and predict its performance, use, and the need for maintenance. If a facility has hundreds of conveyance systems, it's going to be impossible to keep 100% of them operational at any given time; however, a smart monitoring system can get you in the high 90% range.

There are a few key indicators of equipment performance that help in managing these conveyance systems. The following are the basic metrics, required data, and applications to keep systems running smoothly.
