The cascading method works by flowing the condensed water directly onto the hot coils of the air conditioner. These are usually mobile work platforms that can be easily moved to where they are needed, but can also be installed where space for counter-weights, machine room and so forth is limited. The mechanism that makes them go up and down is like that of a scissor jack. The American Society of Mechanical Engineers has a specific section of Safety Code (ASME A17.1 Section 5.3) which addresses Residential Elevators. This section allows for different parameters to alleviate design complexity based on the limited use of a residential elevator by a specific user or user group. Section 5.3 of the ASME A17.1 Safety Code is for Private Residence Elevators, which does not include multi-family dwellings.
- Some hospital elevators will feature a ‘hold’ position on the code-blue key switch which allows the elevator to remain at a floor locked out of service until code blue is deactivated.
- Gearless traction machines are low-speed (low-RPM), high-torque electric motors powered either by AC or DC.
- If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables.
- To help prevent entrapment, when the system detects that it is running low on power, it will bring the running cars to the lobby or nearest floor, open the doors, and shut down.
- Platform and wheelchair elevators are required to comply with ASME A18.1 in most US jurisdictions.
- The elevator will remain parked on a floor with its doors open until a floor is selected and the door close button is held until the elevator starts to travel.

The first and only race circuit in the Caucasian region is located in Georgia. Rustavi International Motorpark originally built in 1978 was re-opened in 2012 after total reconstruction costing $20 million. The track satisfies the FIA Grade 2 requirements and currently hosts the Legends car racing series and Formula Alfa competitions. Georgian culture evolved over thousands of years from its foundations in the Iberian and Colchian civilizations.
< dambrun p>Much of the natural habitat in the low-lying areas of western Georgia has disappeared during the past 100 years because of the agricultural development of the land and urbanization. The large majority of the forests that covered the Colchis plain are now virtually non-existent with the exception of the regions that are included in the national parks and reserves (e.g. Lake Paliastomi area). At present, the forest cover generally remains outside of the low-lying areas and is mainly located along the foothills and the mountains. Western Georgia’s forests consist mainly of deciduous trees below 600 metres above sea level and contain species such as oak, hornbeam, beech, elm, ash, and chestnut. 1000 of all 4000 higher plants of Georgia are endemic to this country. It is unicameral and has 150 members, known as deputies, of whom 30 are elected by plurality to represent single-member districts, and 120 are chosen to represent parties by proportional representation./p>

Tbilisi is its capital as well as its largest city, home to roughly a third of the Georgian population. Guests ascending to the 67th, 69th, and 70th level observation decks (dubbed “Top of the Rock”) atop the GE Building at Rockefeller Center in New York City ride a high-speed glass-top elevator. However, once the cab begins moving, the interior lights turn off and a special blue light above the cab turns on.
The southern portion of the country is bounded by the Lesser Caucasus Mountains. The Greater Caucasus Mountain Range is much higher in elevation than the Lesser Caucasus Mountains, with the highest peaks rising more than 5,000 metres above sea level. Georgia contains two official autonomous regions, of which one has declared independence. Officially autonomous within Georgia, the de facto independent region of Abkhazia declared independence in 1999.
While it is possible for an elevator’s cable to snap, all elevators in the modern era have been fitted with several safety devices which prevent the elevator from simply free-falling and crashing. An elevator cab is typically borne by 2 to 6 redundant hoist cables or belts, each of which is capable on its own of supporting the rated load of the elevator plus twenty-five percent more weight. This device is called the governor, and was invented by Elisha Graves Otis. In addition, an oil/hydraulic or spring or polyurethane or telescopic oil/hydraulic buffer or a combination is installed at the bottom of the shaft to somewhat cushion any impact.
The medieval Georgian Chronicles present an eponymous ancestor of the Kartvelians, Kartlos, a great-grandson of Japheth. However, scholars agree that the word is derived from the Karts, the latter being one of the proto-Georgian tribes that emerged as a dominant group in ancient times. Its root, kartvel-i (ქართველ-ი), specifies an inhabitant of the core central-eastern Georgian region of Kartli, or Iberia as it is known in sources of the Eastern Roman Empire. Ancient Greeks (Strabo, Herodotus, Plutarch, Homer, etc.) and Romans (Titus Livius, Tacitus, etc.) referred to early western Georgians as Colchians and eastern Georgians as Iberians . The Georgian circumfix sa-X-o is a standard geographic construction designating “the area where X dwell”, where X is an ethnonym. The first mention of the name spelled as “Georgia” is in Italian on the mappa mundi of Pietro Vesconte dated AD 1320.
They do not involve the use of an underground piston or a machine room, mitigating environmental concerns; however, they are not allowed by codes in all parts of the United States. The Equitable Life Building, completed in 1870 in New York City, is thought to be the first office building with passenger elevators. In 1845, the Neapolitan architect Gaetano Genovese installed in the Royal Palace of Caserta the “Flying Chair”, an elevator ahead of its time, covered with chestnut wood outside and with maple wood inside.
The country then became embroiled in a bitter civil war, which lasted until nearly 1994. Simmering disputes within two regions of Georgia; Abkhazia and South Ossetia, between local separatists and the majority Georgian populations, erupted into widespread inter-ethnic violence and wars. Supported by Russia, Abkhazia and South Ossetia achieved de facto independence from Georgia, with Georgia retaining control only in small areas of the disputed territories.
