The Central–Mid-Levels escalator and walkway system in Hong Kong is the longest outdoor covered escalator system in the world. The system covers over 800 m (2,600 ft) in distance and traverses an elevation of over 135 m (443 ft) from bottom to top. It opened in 1993 to provide an improved link between Central and the Mid-Levels on Hong Kong ...
Escalator. For the album by Sam Gopal, see Escalator (album). An 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.
A diagram showing the measurements that can be taken from a staircase A quite unusual "variable rise" stairway, which also distorts visual perspective (at The Duomo in Urbino, Italy) The dimensions of a stair, in particular the rise height and going of the steps, should remain the same along the stairs.
Curved structures are constructions generated by one or more generatrices (which can be either curves or surfaces) through geometrical operations. They traditionally differentiate from the other most diffused construction technology, namely the post and lintel , which results from the addition of regular and linear architectural elements.
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them.

The roof of the annex includes a curved skylight with 240 glass panes, and the northern section of the annex's roof is supported by black columns that resemble those in the original tower. The Catalog also contains decorative details, such as handrails and staircase landings, which are inspired by elements of Chicago's "built environment". [ 173 ]
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the ...
