According to the height of the building, use and traffic (or logistics) of the different sets of different types of elevators. At present the basic classification of the elevator roughly as follows.
1, according to the purpose of classification
Passenger elevators, designed for the delivery of passengers to the elevator, requires a sound safety facilities and a certain car decoration.
A cargo elevator, designed primarily for the transport of goods, usually accompanied by an elevator.
Bed elevator, for the delivery of beds, stretchers, medical vehicles and the design of the elevator, the car has a long and narrow features.
Debris lift, for the library, office buildings, hotels, transport books, documents, food and other design of the elevator.
Sightseeing elevator, car wall transparent, for passengers to use the elevator.
Car elevator used as an elevator to transport vehicles.
Ship lifts, elevators used on ships.
Construction of elevators, construction and maintenance of the elevator.
Other types of elevators, in addition to the above commonly used elevators, there are some special-purpose elevators, such as cold storage elevators, explosion-proof elevators, mine elevators, power station elevators, firefighters and elevators.
2, according to the drive way classification
AC elevator, with AC induction motor as the driving force of the elevator. According to the way drag can be divided into single-speed AC, AC double-speed, AC voltage regulator, AC variable frequency drive and so on.
DC elevator, with a DC motor as the driving force of the elevator. The rated speed of such elevators is generally above 2.00m / s.
Hydraulic lift, the general use of electric pumps to drive the liquid flow, the elevator lift by the plunger.
Rack and pinion elevator, the rail processing into racks, the car fitted with gear meshing gear, the motor driven gear rotation to lift the elevator car.
Screw elevator, the straight-top elevator plunger processed into a rectangular thread, and then with a large thrust bearing bearings installed in the cylinder head, and then by the motor through the reducer (or belt) driven nut rotation, so that screw up A car that ascends or descends an elevator.
3, according to the speed classification
Elevator without strict speed classification, China is accustomed to the classification by the following methods.
Low-speed ladder, often refers to less than 1.00m / s speed of the elevator.
In the speed ladder, often refers to the speed of 1.00 ~ 2.00m / s elevator.
High-speed ladder, often refers to the speed is greater than 2.00m / s elevator.
ltra-high-speed ladder, the speed of more than 5.00m / s of the elevator.
With the continuous development of elevator technology, the elevator speed is getting higher and higher, the difference between high, medium and low speed elevator limits are also correspondingly increased.
4, according to the control and control methods
Handle switch manipulation, the elevator driver in the car control joystick handle switch to achieve the lift start, rise, fall, leveling, stop running.
Button control elevator: is a simple automatic control of the elevator, with automatic leveling function, a common car outside the button control, car control buttons within the two control methods.
Signal control elevator, which is a higher degree of automatic control of a driver elevator. In addition to automatic leveling, automatic door open function, still has the car command registration, landing registration, automatic stop layer, forward stop and automatic reversing and other functions.
Selective control elevator, is a signal control developed on the basis of fully automatic control of the elevator, and signal control is the main difference between the driver can achieve no control.
Parallel control of the elevator, 2 to 3 elevators of the control circuit in parallel logic control, common layer outside the station call button, the elevator itself has a set of election function.
Group control elevator, is the use of computer control and unified scheduling of multiple parallel central elevator. Group control with a ladder of program control, ladder group intelligent control and other forms.
