Shanghai TowerShanghai Tower () is a 128-story, megatall skyscraper in Lujiazui, Pudong, Shanghai. It is the tallest building in China and the world's third-tallest building by height to architectural top. It is the tallest and largest LEED Platinum certified building in the world since 2015. It shares the record (along with the Ping An Finance Center) of having the world's highest observation deck within a building or structure at 562 m. It had the world's second-fastest elevators at a top speed of until 2017, when it was surpassed by the Guangzhou CTF Finance Center, with its top speed of .
Moving walkwayA moving walkway, also known as an autowalk, moving pavement, moving sidewalk, people-mover, travolator, or travelator (British English), is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction. The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois, in the United States as The Great Wharf Moving Sidewalk and was designed by architect Joseph Lyman Silsbee.
Public transportPublic transport (also known as public transportation, public transit, mass transit, or simply transit) is a system of transport for passengers by group travel systems available for use by the general public unlike private transport, typically managed on a schedule, operated on established routes, and that charge a posted fee for each trip. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc.
Safety-critical systemA safety-critical system (SCS) or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: death or serious injury to people loss or severe damage to equipment/property environmental harm A safety-related system (or sometimes safety-involved system) comprises everything (hardware, software, and human aspects) needed to perform one or more safety functions, in which failure would cause a significant increase in the safety risk for the people or envi
Burj KhalifaThe Burj Khalifa (known as the Burj Dubai prior to its inauguration in 2010) is a skyscraper in Dubai, United Arab Emirates. It is the world's tallest building. With a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding antenna, but including a 242.6 m spire) of , the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009, supplanting Taipei 101, the previous holder of that status.
Sky lobbyA sky lobby is an intermediate interchange floor in a skyscraper where people can change from an express elevator that stops only at the sky lobby to a local elevator that stops at a subset of higher floors. When designing supertall buildings, supplying enough elevators is a problem – travellers wanting to reach a specific higher floor may conceivably have to stop at a very large number of other floors on the way up to let other passengers off and on.
WinchA winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches.
Fail-safeIn engineering, a fail-safe is a design feature or practice that, in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people. Unlike inherent safety to a particular hazard, a system being "fail-safe" does not mean that failure is impossible or improbable, but rather that the system's design prevents or mitigates unsafe consequences of the system's failure.
Taipei 101Taipei 101 (; stylized as TAIPEI 101), formerly known as the Taipei World Financial Center, is a skyscraper in the capital Taipei, Taiwan. The building was officially classified as the world's tallest from its opening in 2004 until the 2010 completion of the Burj Khalifa. Upon completion, it became the world's first skyscraper to exceed a height of half a kilometer (about 0.3 miles). Taipei 101 is the tallest building in Taiwan. The elevators of Taipei 101 that transport passengers from the 5th to the 89th floor in 37 seconds (attaining ) set speed records.
EscalatorAn escalator is a moving staircase which carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal. Escalators are often used around the world in places where lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, transit systems (railway/railroad stations), convention centers, hotels, arenas, stadiums and public buildings.
