Elevators move large numbers of people up and down each day, mostly without incident, thanks to a strongly developed system of safety measures and the work of highly trained and experienced professionals. In performing elevator maintenance and repair, there are numerous technical factors, not to mention huge moral and legal issues. Workers need to fully understand proper maintenance procedures so that all safeguards remain in effect. It's also essential to be aware of applicable regulations, and to maintain compliance at all times. For those serious about engaging in elevator work, the appropriate licenses must be acquired--an electrician's license and elevator mechanic's license. These are not achieved overnight. This work covers everything a student or current technician needs to know to perform elevator diagnosis, maintenance, troubleshooting, and repair, and details all the knowledge a technician must have to properly service elevators in various situations. It is also the only work that includes helpful questions and corresponding answers for those who are studying to obtain their elevator mechanic's license. Features Offers sample certification questions and answers for those looking to get their Elevator Mechanic's license. Places an emphasis on safety interlocks and the elevator system as a whole. Includes a history of elevators to give readers perspective on the industry and advancements in technology to date. Written by a renowned electrician with regular columns and contributions in Elevator World and Electrical Construction and Maintenance magazines.

Before skyscrapers forever transformed the landscape of the modern metropolis, the conveyance that made them possible had to be created. Invented in New York in the 1850s, the elevator became an urban fact of life on both sides of the Atlantic by the early twentieth century. While it may at first glance seem a modest innovation, it had wide-ranging effects, from fundamentally restructuring building design to reinforcing social class hierarchies by moving luxury apartments to upper levels, previously the domain of the lower classes. The cramped elevator cabin itself served as a reflection of life in modern growing cities, as a space of simultaneous intimacy and anonymity, constantly in motion. In this elegant and fascinating book, Andreas Bernard explores how the appearance of this new element changed notions of verticality and urban space. Transforming such landmarks as the Waldorf-Astoria and Ritz Tower in New York, he traces how the elevator quickly took hold in large American cities while gaining much slower acceptance in European cities like Paris and Berlin. Combining technological and architectural history with the literary and cinematic, Bernard opens up new ways of looking at the elevator--as a secular confessional when stalled between floors or as a recurring space in which couples fall in love. Rising upwards through modernity, Lifted takes the reader on a compelling ride through the history of the elevator.
