Points That Make Glass Elevators Score Over Other Lifts
Aesthetically speaking glass elevators are beautiful additions which only enhance the attraction of the architectural design of the building concerned. The clear hoist-way combined with an all glass car makes for a classically elegant appearance that can blend in with all types of decor. In fact the view experienced by the passengers of this all glass capsule is panoramic beyond comprehension. Yet the glass elevator is not just a device of beauty, its utility far exceeds its attractive power. It comes with a host of benefits which make it a popular device to install. However there are also certain limitations associated with these glass elevators like: - They cannot be used in high-rises and skyscrapers since its power to propel the glass capsule is only limited to the height of about 3 floors or storeys. - They can only a small number of people at a time which acts as a hindrance for its installation in places which experience a daily heavy footfall. Unique qualities of glass elevators In spite of the limitations prevalent, a glass elevator is still a very popular device. This is because it comes with certain unique characteristics which are interesting and intriguing. Some of its distinctive qualities are: - The fact that it is fully made of glass is as shocking as it is surprising. While real glass is rarely used to make these glass capsules, polycarbonates are commonly used as a perfect replacement for glass. This is because polycarbonates are cheaper and much stronger than glass. The use of polycarbonates, thus, helps increase the safety factor of a glass elevator. - These elevators also do not use the traditional accessories required to make the lift work like cables, motors, lubricants or gears. It works fully on air and its mechanism involves the following: -> In case a passenger wants to ascend up to the next level, the pressure above the car is lowered with the use of a pump. -> The air pressure below becomes more than that above and this propels the elevator car to the next level. -> The elevator car only stops at the level at which the air pressure below and above become the same. This level is decided by the passenger when he presses the button for the level he wants to travel to. Once the level comes, steel brakes additionally help to secure it to the landing of the concerned floor. -> When the rider wants to come down using the glass elevator, the air pressure below is lowered and the elevator car falls to the desired level wherein both the air pressures tend to become equal and balance each other. This again results in the steel brakes coming into action to ensure stability of the lift on that floor landing. -> These glass elevators might be small but the large ones have enough space to fit in other mobility options like a wheelchair lifts. This makes it an ideal proposition even for homes wherein one or more resident might have limited or no mobility. Overcoming the disadvantages With advancement in technology, people are looking at an integrated design involving the advantages of both traditional and pneumatic glass elevators. This will make it possible for these elevator cars to be propelled both by air pressure and by cables. Simply put, glass elevators using pneumatic vacuum propelling are generally used for residences and small buildings which have limited time and budget. On the other hand the same elevators can be used in high-rises along with cables, motor and a sheave to broaden its scope of action and give rise to beautiful devices of utility.
