What is Electro Magnetic Levitation?
Definition of Electro Magnetic Levitation in Construction
This is the use of opposing magnetic forces, to levitate an elevator cab, between the rail systems within the elevator shaft.
This is a new technology, that has solved the height limitations placed on cable elevators, due to the tremendous weights of the cables, as the service heights increased. The use of an electro- magnetic field, to suspend the cab within the elevator shaft has revolutionized the ability of elevators to service super high structures.
In addition, the use of this type of system eliminates the number of cars that can be located within the same elevator shaft. This type of system allows an elevator cab that can actually move horizontally as well as vertically. By using this concept , several elevator cabs can exist within the same shaft, they simply move on a continuous circuit, servicing both the upward and downward needs of the structure. The elevator servicing of the structure becomes basically a continuous movement of several elevator cabs, both up and down within the structure. Mechanical braking systems for this type of elevator have advanced to eliminate the fear of free falling down the elevator shafts. The only limit to the system, is the number of elevator cabs that can be supported by one elevator shaft. The timing of the entering and exiting of the elevator cabs themselves will be the only limitation on how many cabs will be located within one elevator shaft.
