We live in a world filled with personal and mainframe computers, and modern elevator control systems that include sophisticated microprocessors to perform the many functions associated with providing the best possible elevator transportation. However, elevator maintenance work is still a mix of the old and the new.
Elevator control systems installed today, by any mainstream elevator company, are much easier to maintain than those installed only a decade ago. They have far fewer parts to replace on a regular basis; are much more reliable and work better; and can even tell technicians what is wrong with the control system through a self-diagnostic system that collects fault codes for many malfunctions of the elevator control system and associated mechanical components.
However, an elevator installation contains many more components–impacted by normal wear and tear–than can be classified as the elevator control system. Numerous mechanical and electromechanical devices open and close doors, drive elevator equipment from floor to floor, and cause the elevator to stop in the event of an over-speed condition. These devices on new elevators require nearly as much routine preventive maintenance as they have in the past, making it essential to have an extremely high-quality elevator maintenance specification in place at all times.
