If you own a building in a city that is famous for its skyscrapers, you should consider adding a sightseeing elevator. A sightseeing elevator will give your passengers a better view of the city and the surrounding scenery. Apart from the added benefit of providing an excellent ride for your customers, a sightseeing elevator can add a great deal of value to your building. When choosing a sightseeing elevator, check for the safety features it offers: it should have a working alarm system, a driving indoor phone, a power-failure backup, and a slack chain braking system.
