71-403: Hilly landscape is the reason for the unusual depths and two-fold escalators of underground Kyiv Metro ( subway ) stations in the city center (with the deepest one, Arsenalna , measuring 105.5 metres). The Kyiv plateau as a geologic creation presents itself as a rolling meadow plain dissected with ravines and gulches. According to the physiographic categorization the given territory is part of

142-481: A mystical prehistory, supposedly being one of the lysi hory ("bald mountains") - the sites of the witch gatherings. Geographically, it is really "bald" (lacking trees) from several sides. In the 18th century a cemetery was established on the hill (now abandoned). It is now a small landscape park in Podil Raion still containing interesting grave monuments. Zamkova Hora is also one of two hills that border

213-533: 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. Escalators have

284-464: A factory, handrails are constructed by feeding rubber through an extrusion machine to produce layers of the required size and type in order to match specific orders. The component layers of fabric, rubber and steel are shaped by workers before being fed into the presses which fuse them together. In the mid-twentieth century, some handrail designs consisted of a rubber bellows, with rings of smooth metal cladding called "bracelets" between each coil. This gave

355-460: A handhold for passengers while they are riding the escalator. The handrail is pulled along its own track by a chain that is connected to the main drive gear by a series of pulleys, keeping it at the same speed as the steps. Four distinct sections make up the rail: at its center is a "slider", also known as a "glider ply", which is a layer of a cotton or synthetic textile that allows the rail to move smoothly along its track. The " tension member " lies on

426-451: A period of several months in 2016. This increased capacity and eliminated queues approaching the escalator during peak travel times. A follow-up report was released several months later with no recommendation to continue the practice. Zamkova Hora (Kyiv) Zamkova Hora ( Ukrainian : Замкова Гора , literally Castle Hill ) in Kyiv , Ukraine is a historical landmark in the center of

497-432: A single-width escalator traveling at about 0.5 metres per second ( 1 + 1 ⁄ 2  ft/s) can move about 2000 people per hour, assuming that passengers ride single file. The carrying capacity of an escalator system is typically matched to the expected peak traffic demand. For example, escalators at transit stations must be designed to cater for the peak traffic flow discharged from a train, without excessive bunching at

568-542: A spiral escalator by 1973. When interviewed for the Los Angeles Times that year, Luna was in the process of soliciting major firms for the acquisition of his patents and company, but statistics are unclear on the outcome of these endeavors. Karl-Heinz Pahl received a European and a US patent for a spiral escalator in 1992. The Mitsubishi Electric Corporation was most successful in its development of spiral or helical escalators, and it alone has sold them since

639-400: A staircase; a ladder, [or] a scaling-ladder." The alleged intended capitalization of "escalator" is likewise a topic of debate. Seeberger's trademark application lists the word not only with the "E", but also with all of the letters capitalized (in two different instances), and he specifies that "any other form and character of type may be employed... without altering in any essential manner

710-432: A time, and then exploded into the ticket hall above in a previously unrecognised phenomenon now known as the " trench effect ". In the escalators' undercarriage, approximately 8,800 kilograms (19,400 lb) of accumulated detritus acted as a wick to a neglected buildup of interior lubricants; wood veneers, paper and plastic advertisements, solvent-based paint, plywood in the ticket hall, and melamine combustion added to

781-482: A title for it. As evidenced in Seeberger's handwritten documents, the inventor consulted "a Latin lexicon" and "adopted as the root of the new word, 'Scala'; as a prefix, 'E' and as a suffix, 'Tor.'" His own rough translation of the word thus created was "means of traversing from", and he intended for the word to be pronounced / ɛ s ˈ k æ l ə t ɔːr / ( ess- KAL -ə-tor ). By 1906, Seeberger noted that

To the northwest of Old Kyiv is located the Castle Hill ( Zamkova Hora ), the highest point of which reaches 169.1 m (555 ft). The hill is little bit elongated with depression. Relatively close to the Castle Hill is located the Oleh Hill or Shchekavytsia ,

923-451: Is also sometimes provided by adding automatic sprinklers or fireproof shutters to the opening, or by installing the escalator in an enclosed fire-protected space. The King's Cross fire of 1987 illustrated the demanding nature of escalator upkeep and the devices' propensity to collect "fluff" and other small debris when not properly maintained. The official inquiry determined that the fire started slowly, smoldering virtually undetected for

994-439: Is credited with patenting the first "escalator" in 1859, even though no working model of his design was ever built. His invention, the "revolving stairs", is largely speculative and the patent specifications indicate that he had no preference for materials or potential use (he noted that steps could be upholstered or made of wood, and suggested that the units might benefit the infirm within a household use). The suggested motive power

1065-432: Is separated and load/unload areas are other important considerations. Temporal traffic patterns must be anticipated. Some escalators need only to move people from one floor to another, but others may have specific requirements, such as funneling visitors towards exits or exhibits. The visibility and accessibility of the escalator to traffic is relevant. Designers need to account for the projected traffic volumes. For example,

1136-464: Is the Old Kyiv Hill ( Starokyivska ) and its northeastern portion, the St.Michael's Hill ( Mykhailivska ). Before they were separated by a ravine that stretched across the St.Michael's Square and Kyiv Funicular . On the eastern rise of the St.Michael's Hill is located a park, Volodymyr Hill , the name of which derived from the monument to St.Volodymyr located in it. A little bit lower is the northern side of

1207-465: Is the hollow metal structure that bridges the lower and upper landings, composed of two side sections joined with cross braces across the bottom and just below the top. The ends of the truss are attached to the top and bottom landing platforms via steel or concrete supports. It carries all the straight track sections connecting the upper and lower sections. The balustrade is composed of handrails, balustrade panels, and skirt panels. The handrail provides

1278-542: The Andriyivskyy Descent . Reclaiming the mystical essence of the hill, local satanist groups have conducted their ceremonies there since late 1980s. Small ritual structures were covertly built on site. Castle Hill has a unique fauna. The old trees provide hiding places for rare species of bats and attract a large number of birds, including owls (gray and eared). Fruit trees attract the Syrian woodpecker and

1349-610: The Boston subway until construction for the Big Dig ( c.  1991 ) precipitated their removal. The Smithsonian Institution considered re-assembling one of these historic units from 1914 in their collection of Americana, but "logistics and reassembly costs won out over nostalgia", and the project was discarded. Around May 1895, Charles Seeberger began drawings on a form of escalator similar to those patented by Wheeler in 1892. This device consisted of flat, moving stairs, not unlike

1420-630: The Fahrtreppe in 1906. After the Exposition , Hallé continued to sell its escalator device in Europe but was eventually eclipsed in sales by other major manufacturers. In the first half of the twentieth century, several manufacturers developed their own escalator products, though they had to market their devices under different names, due to Otis’ hold on the trademark rights to the word "escalator." New York -based Peelle Company called their models

1491-710: The London Transport Museum 's depot in Acton . Although the first fully operational spiral escalator, Reno's design was nonetheless only one in a series of similar proposed contraptions. Souder patented two helical designs, while Wheeler drafted helical stairway plans in 1905. Seeberger devised at least two helical designs between 1906 and 1911 (including an unrealized arrangement for the London Underground), and Gilbert Luna obtained West German, Japanese, and United States patents for his version of

1562-528: The Prague metro , escalator users are encouraged to stand on whichever side they choose, with the aim of preventing wear and tear and asymmetrical burdening. All Tokyo metro stations also have posters next to the escalators that ask users not to walk but instead to stand on either side. The practice of standing on one side and walking on the other may cause uneven wear on escalator mechanisms. Transport for London trialed standing on both sides (no walking) for

1633-551: The 1930s, at least one suit was filed against a department store, alleging that its escalators posed an attractive nuisance , responsible for a child's injury. Despite their considerable scope, the two Congressional Acts regarding accessibility (the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990 (ADA) ) did not directly affect escalators or their public installations. Since Section 504 of

As the last of the "big four" manufacturers to emerge onto the global market, Kone first acquired the Montgomery Elevator company, then took control of Germany's Orenstein & Koppel Rolltreppen . In

1775-547: The Examiner of Trademark Interferences, Assistant Commissioner of Patents Murphy's decision rejected Otis’ appeal to keep their trademark intact, and noted that "the term 'escalator' is recognized by the general public as the name for a moving stairway and not the source thereof", observing that Otis had "used the term as a generic descriptive term... in a number of patents which [had] been issued to them and... in their advertising matter." All trademark protections were removed from

Somewhat lower marks are in front of the Verkhovna Rada building ( Constitution Square ) – 195 m (640 ft). Considering that the absolute water level in Dnieper is recorded at 91.5 m (300 ft),

1917-608: The Motorstair, while Westinghouse called their model an Electric Stairway. The Toledo -based Haughton Elevator company referred to their product as simply Moving Stairs. The Otis trademark is no longer in effect. Kone and Schindler introduced their first escalator models several decades after the Otis Elevator Co., but grew to dominate the field over time. Today, Mitsubishi and ThyssenKrupp are Otis's primary rivals. Kone expanded internationally by acquisition in

The plateau stretches along the right bank of Dnieper from Kyiv to Kaniv where a complex of other hills compose a landscape feature known as Kaniv Mountains. At the heart of the upland lay Jurassic , Cretaceous , Paleogene , Neogene and Quaternary deposits that are covered with a thick layer of loess on which formed gray and lightly gray limed silt of light loam . Creation of

2059-666: The Old Iron Pier at Coney Island , New York City in 1896. This particular device was little more than an inclined belt with cast-iron slats or cleats on the surface for traction, and traveled along a 25 degree incline. A few months later, the same prototype was used for a month-long trial period on the Manhattan side of the Brooklyn Bridge . Reno eventually joined forces with Otis and retired once he had sold his patents. Some Reno-type escalators were still being used in

2130-743: The Old Kyiv Hill, Dytynets , 185.1 m (607 ft). There in place of the Kyi Fort is located the National Museum of History of Ukraine. Beyond the Andrew's Descent is the Old Kyiv's spur, St. Andrew's Hill ( Andriyivska ) which is 167.7 m (550 ft) in height. Before, the St.Andrew's Hill was connected with the Castle Hill , but the Andrew's Descent divided them. The hill's name

2201-845: The Rehabilitation Act included public transportation systems, for a few years, the United States Department of Transportation considered designs to retrofit existing escalators for wheelchair access. Nonetheless, Foster-Miller Associates ' 1980 plan, Escalator Modification for the Handicapped was ultimately ignored in favor of increased elevator installations in subway systems. Likewise, the ADA provided more accessibility options, but expressly excluded escalators as "accessible means of egress", advocating neither their removal nor their retention in public structures.

Practice may differ from city to city within countries: in Osaka , riders stand on the right, whereas in Tokyo (and most other Japanese cities), riders stand on the left. In certain high-traffic systems, including the East Japan Railway Company and

2343-500: The United States and Canada, new escalators must abide by ASME A17.1 standards, and old/historic escalators must conform to the safety guidelines of ASME A17.3. In Europe, the escalator safety code is EN 115. In most major countries, the expectation is that escalator users wishing to stand keep to one side to allow others to climb past them on the other. Due to historical design purposes, riders in Canada, Germany, Hong Kong, Taiwan,

2414-399: The back wheels of the steps (called the trailer-wheel track). The relative positions of these tracks cause the steps to form a staircase as they move out from under the comb plate. Along the straight section of the truss the tracks are at their maximum distance apart. This configuration forces the back of one step to be at a 90-degree angle relative to the step behind it. This right angle forces

They can be used to guide people toward main exits or special exhibits and may be weatherproofed for outdoor use. A non-functional escalator can function as a normal staircase, whereas many other methods of transport become useless when they break down or lose power. Nathan Ames , a patent attorney from Saugus, Massachusetts ,

The Lithuanian castle had 18 towers. Other names: Khorevytsya, Kyselivka, Frolovska, Lysa Hora. Some important events of Ukrainian history took place on the hill. According to some researchers, Zamkova Hora also has

Noted by Bill Lancaster in The Department Store: a Social History , "customers unnerved by the experience were revived by shopmen dispensing free smelling salts and cognac." The Harrods unit was a continuous leather belt made of "224 pieces... strongly linked together traveling in an upward direction", and was the first "moving staircase" in England. Hocquardt received European patent rights for

2769-401: The ends of the escalator truss. Each platform also has a floor and a comb bearer. The floor plate provides a place for the passengers to stand before they step onto the moving stairs, flush with the rest of the floor and are removable to allow easy engineer access, while the comb bearer sits between the stationary floor plate and the moving step, so named for the cleats on its edge which mesh with

2840-499: The escalator entrance. In this regard, escalators help manage the flow of people. For example, at many airports an unpaired escalator delivers passengers to an exit, with no means for anyone entering at the exit to access the concourse. Escalators are often built next to or around staircases that allow alternative travel between the same two floors. Elevators are necessary for disability access to floors serviced by escalators. Escalators typically rise at an angle of 30 or 35 degrees from

2982-434: The escalators of today, except for one important detail: the step surface was smooth, with no comb effect to safely guide the rider's feet off at the ends. Instead, the passenger had to step off sideways. To facilitate this, at the top or bottom of the escalator the steps continued moving horizontally beyond the end of the handrail (like a miniature moving sidewalk) until they disappeared under a triangular "divider" which guided

3053-428: The ground. They move at 0.3–0.9 metres per second (1–3 ft/s), like moving walkways , and may traverse vertical distances in excess of 18 metres (60 ft). Most modern escalators have single-piece aluminum or stainless steel steps that move on a system of tracks in a continuous loop. Different types of escalator planning include: Most countries require escalators to have moving handrails that keep pace with

3124-441: The handrail a rigid yet flexible feel. Additionally, each bellows section was no more than around a metre long, so if part of the handrail was damaged, only the bad segment needed to be replaced. These forms of handrail have largely been replaced with fabric-and-rubber railings. Being made of either metal, sandwich panel , or glass, the balustrade panel supports the handrails of the escalator. It also provides additional protection for

3195-437: The handrail and passengers. Some escalators have direction arrows on the ends of the balustrade. Escalators' on/off buttons are frequently located at the ends of the balustrade. Moving walkways often use balustrades in the same way. The bottom of the balustrade is called a skirt panel. It is notorious in this art for being a frequent site of injuries and failures, due to the possible entrapment of materials (including body parts) in

3337-597: The impact of the calamity. Following the report, older wooden escalators were removed from service in the London Underground . Additionally, sections of the London Underground that were actually below ground were made non-smoking ; ultimately, the whole system became a smoke-free zone. Some of longest and fastest escalators in Europe are found in Prague , and are set to be replaced with slower versions in order to meet modern safety standards. In

3408-728: The in-use steps: rather, they provide steps for travel in the opposite direction, as in the Pahl spiral escalator patent. Safety is a major concern in escalator design, as escalators are powerful machines that can become entangled with clothing and other items. Such entanglements can injure or kill riders. In India many women wear saris , increasing the likelihood of entangling the clothing's loose end. To prevent this, sari guards are built into most escalators in India. Children wearing footwear such as Crocs and flip-flops are especially at risk of being caught in escalator mechanisms. The softness of

The highest elevation of the Kyiv Mountains is an upland that corresponds to historic city neighborhood Pechersk (Caves). Sometimes it is referred to as Pechersk Hills or Pechersk Elevation. The highest elevated location of the upland is situated at Lypky and known as Levashov Hill (after

3550-414: The machinery. Multiple solutions have been suggested for this issue, including coating with a low-friction material, employing bristles, and others. The track system is built into the truss to guide the step chain, which continuously pulls the steps from the bottom platform and back to the top in an endless loop. One track guides the front wheels of the steps (called the step-wheel track) and another guides

3621-543: The matching cleats on each step (and resemble a comb). The comb plates, which bolt to the comb bearer (usually 4 or 5 depending on the width of the machine), help to minimize the gap between the stairs and landing, preventing objects or persons from becoming caught in it. The comb bearer, depending on what brand of the escalator will push back and/or up and activate limit switches in the event of an impact of something that jams through combs (typically stones, screws & popcorn) can be someone's shoe/item loose clothing. The truss

3692-413: The mid-1980s. The world's first practical spiral escalator—a Mitsubishi model—was installed in Osaka , Japan, in 1985. Helixator, an experimental helical escalator design that currently exists as a prototype scale model, could further reduce floor space demands. Its design has several innovations that allow a continuous helix; driven by a linear motor instead of a chain system, it spreads force evenly along

3763-489: The movement of the steps as a safety measure. This helps riders steady themselves, especially when stepping onto the moving stairs. Occasionally a handrail moves at a slightly different speed from the steps, causing it to "creep" slowly forward or backward relative to the steps; it is only slippage and normal wear that causes such losses of synchronicity, and is not by design. The direction of escalator movement (up or down) can be permanently set, controlled manually depending on

3834-710: The passenger to either side. Seeberger teamed with Otis in 1899, and together they produced the first commercial escalator. It won first prize at the 1900 Paris Exposition Universelle . Also on display at the Exposition were Reno's inclined elevator, a similar model by James M. Dodge and the Link Belt Machinery Co., and two different devices by the French manufacturers Hallé and Piat. Piat installed its "stepless" escalator in Harrods Knightsbridge store on Wednesday, November 16, 1898, though

Landing platforms are the two platforms (at the two ends) that house the curved sections of the tracks, as well as the gears and motors that drive the stairs. The top platform usually contains the motor assembly and the main drive gear, while the bottom holds the return gear. These sections also anchor

3976-532: The public had instead come to pronounce it / ˈ ɛ s k ə l eɪ t ɔːr / ( ess-kal- ATE -or ). "Escalator" was not a combination of other French or Greek words, and was never a derivative of " elevator " in the original sense, which means "one who raises up, a deliverer" in Latin. Similarly, the root word " scala " does not mean "a flight of steps", but is the singular form of the plural noun " scalae ", which can denote any of: "a flight of steps or stairs,

Seeberger escalators featured flat treads and smooth risers; other escalator models have cleated treads and smooth risers. The steps are linked by a continuous metal chain that forms a closed loop. The front and back edges of

4189-548: The shoe's material combined with the smaller size of children's feet makes this sort of accident especially common. Escalators sometimes include fire protection systems including automatic fire detection and suppression systems within the dust collection and engineer pit. To limit the danger caused by overheating, spaces that contain motors and gears typically include additional ventilation. Small, targeted clean agent automatic extinguishing systems are sometimes installed in these areas. Fire protection of an escalator floor opening

The inner components, on top of the tension member, are made of chemically treated rubber designed to prevent the layers from separating. Finally, the outer layer—the part that passengers see—is the cover, typically a blend of synthetic polymers and rubber. Covers are designed to resist degradation from environmental conditions, mechanical wear and tear and vandalism. In

For reference, contradictory citations by seven separate individuals, including the Otis Elevator Company itself, are provided below. Seeberger trademarked the word "escalator" in 1900, to coincide with his device's debut at the Exposition universelle . According to his own account, in 1895, his legal counsel advised him to name his new invention, and he then set out to devise

4402-429: The steps each have two wheels, the rear of which are set further apart and fit into the trailer-wheel track while the front set have narrower axles and fit the step-wheel track. Jesse Reno also designed the first escalators installed in any underground subway system in the form of a helical escalator at Holloway Road tube station in London in 1906. The experimental device never saw public use and its remains are now in

4473-399: The steps into a shape resembling a staircase. At the top and bottom of the escalator, the two tracks converge so that the front and back wheels of the steps are almost in a straight line. This causes the stairs to lay in a flat sheetlike arrangement, one after another, so they can easily travel around the bend in the curved section of track. The tracks carry the steps down along the underside of

At this point, the tracks separate and the steps once again assume a staircase configuration. This cycle is repeated continually as the steps are pulled from bottom to top and back to the bottom again. The steps themselves are solid, one piece, die-cast aluminium or steel. Yellow demarcation lines are sometimes added to indicate their edges. In most escalator models manufactured after 1950, both

4615-715: The twenty-first century Schindler became the largest maker of escalators and second largest maker of elevators in the world, though their first escalator installation did not occur until 1936. In 1979, the company entered the United States market by purchasing the Haughton Elevator company. A decade later, Schindler assumed control of the North American escalator/elevator operations of Westinghouse, forming Schindler's American division . Notable examples of historic escalators still in operation include: Authors and historians have offered multiple interpretations of

Today there is the Hryshko National Botanic Garden . The highest point of the hill (188.8 m (619 ft)) is southeast of the botanic garden entrance. Beside the Bous Field, at the north of the hill lays Zvirynets neighborhood that is more famous therefore

4757-763: The whole area sometimes is called "Zvirynets". To the Pechersk Hills is adjacent the Cherepanov Hill, the height of which is 184.9 m (607 ft). On the hill were erected Hospital fortifications of the Kyiv Fortress and the Military Hospital, while at the northwestern foot of the hill is located the Olimpiyskiy National Sports Complex . Practically of the same height (187.7 m (616 ft))

Design factors include innovative technology, physical requirements, location, traffic patterns, safety considerations, and aesthetics. Physical factors such as the distance to be spanned determine the length and pitch of the escalator, while factors such as the infrastructure's ability to provide support and power must be considered. How upward and downward traffic

Wheeler's patents were bought by Charles Seeberger ; some features of Wheeler's designs were incorporated in Seeberger's prototype that was built by the Otis Elevator Company in 1899. Reno , a graduate of Lehigh University , produced the first working escalator (called the "inclined elevator") and installed it alongside

No model was ever built. This was the first of at least four escalator-style patents issued to Souder, including two for spiral designs. On March 15, 1892, Jesse W. Reno patented the "Endless Conveyor or Elevator." A few months after Reno's patent
