The Benefits And Advantages Of Pneumatic Vacuum Elevators
Elevators are popular and mandatory additions to residential and commercial buildings as they enable increased mobility. In fact today there have gone beyond being mere utilities to being fashionable items of architecture. Hence they are increasingly used not only for their utility but also for their aesthetics.Elevators today are primarily differentiated into four different types on the basis of their mode of operation. They are the- Hydraulic elevators which have cylinders placed either above or below the ground or use a combination of above ground cylinder and a steel rope system to operate the elevators,- Traction type elevators which use sheaves to roll hoist ropes made of steel with or without the help of a gear box,- Climbing elevators which use a self propelling combustion or electrical engine to move the elevator and- Pneumatic elevators which use air pressure to lift and lower the elevators.While each has its specific advantages and disadvantages, Pneumatic elevators are undoubtedly the most interesting of all the elevator types.What are pneumatic elevators?These types of elevators are lifted and lowered by controlling air pressure created using vacuum pumps or turbines in a compartment usually placed strategically under the lift. Building of air pressure results in the elevator getting hoisted while gradual release of the same results in the lowering of the elevator. Also known as vacuum elevators, they are thus operated without cables and can be quickly and easily installed. They are generally built using prefabricated transparent sections, relatively narrower than the other lift shafts. These sections allow for a 360 degree view which is at the same time breath-taking and marvellous for the passenger.With its bullet shape and exteriors made entirely of glass, it is perhaps the only elevator which effectively looks like a bubble going up and down a transparent tube.Advantages of pneumatic elevatorsThese elevators are easy to install, operate and maintain than the other traditional types of elevators. This accounts for its biggest advantage. Also the compact design of the vacuum elevator facilitates its installation even in houses which have already been built. This is a difficult proposition for traditional elevators which require the excavation of a pit for their installation. Since the vacuum elevator uses air-pressure regulation to function, its installation also does not need the presence of costly and heavy machinery. This considerably reduces its cost of installation.Aesthetically speaking these elevators are very sleek looking and super attractive making them blend in easily with any home or facility. They are low maintenance devices literally having zero energy consumption during its descent. While ascending it requires the use of a turbine of 220volts. This makes it one of the most energy efficient devices of the modern times and also accounts for its low cost maintenance.Safety is another area where pneumatic elevators scores above the other traditional types of elevators. The simple principles and laws of physics that are used to design it make it almost impossible to undergo a freefall or get stuck between floors. It would not be wrong to say that a pneumatic elevator simply cannot fall thereby making it the safest elevator to install and use. Even during a power failure, the elevator automatically descends to the ground floor as it requires no power for descent.These elevators are also environment friendly as it leaves behind minimal carbon footprints. The amount of load that it can take at a time is about 450pounds which is equivalent to approximately two people. It can travel about 35feet at a time with a speed of up to 30feet in a minute. This makes a perfect choice for installation in homes or small buildings not more than 3 storeys in height.
