Elevator types according to the signal control

Elevator types according to the signal control

1.Handle switch control elevator

The driver rotation handle position (open / closed) to control the elevator running or stop.This kind of elevator is very rare to see now.

2.Button control elevator

Push the elevator button to control the operation of the inner layer station.When push the call button in a service floor,then the elevator starts to run to respond and stop at this floor.

During the operation of the elevator, if there are other layer station call button press,the system can only keep the signal down, not to answer, but also cannot take the elevator stopped.Until the elevator is completed all the response to the operation of the station before,then the station can respond to other layer station call signal. It is generally used for dumbwaiters or small elevators.

3.Signal control elevator

Signal control elevator collected the call signal of each layer of station,the call signal which is consistent with the running direction of the elevator is arranged in order and the elevator will stop at these floors to pick up the passengers.

Elevator operator is controlled by elevator operator,and the elevator will stop at any level station by the car call button signal or hall button signal.

4.Selective collected control elevator

It is based on the signal control,and collected all the call signal to have a choice of response.The elevator is no driver,can automatically respond to call signal of all the layers in the same direction when the elevator is running.And if no call signal,elevator will stand by at the base station.

In order to adapt to the characteristics of this control,the elevator designs with the door protection device and overload protection device with safety contact plate.

Now most of the commercial elevators and residential elevators are selective collected control mode.

5. Parallel control elevator

Parallel control elevator sharing a set of call signal system,make the two or three sets elevators with same size in parallel to control.

If no passengers use the elevator, often have a lift dock at the base station, the lift is called the base elevator.And the others stop at the pre -selected layer station,we call it flexible elevator.

6.Group control elevator

High rise building with multiple elevators, is divided into several groups, each group of 8 - 3 sets of elevators.The elevators in each group share a signal system.By the elevator group control system, elevator operation coordination with each other, in order to improve the service performance of the elevator system.

Good elevator group control system will keep the most appropriate way to answer call signal based on different passenger traffic demand in the building.

Main parameters of Elevator type selection and configuration

Now more and more buildings installed with elevator equipment,so the investors and designers will meet such problem---How to choose the elevator for your project? Now we talked about the main parameters of elevator type selection and configuration combined with elevator technical issues.

First, we mush know the two concepts commonly used in elevator configuration.

● Capacity

Which is the number of passengers who can be transported by a single passenger elevator at one time.

● Average run time

The running time interval between 2 adjacent to the main floor of the car cabin.

If for several group control elevators,the time will divide to the elevator numbers.

The main parameters of the elevator type configuration are the following:

1.The numbers of elevator

Calculation according to the use of buildings and the flow of personnel inside,with the least amount of investment to meet the reasonable requirements of the vertical transport.Some need to calculate the elevator units by per hundred persons,some calculated per capita area of the building.While the most reasonable scientific method is to carry out traffic calculations.

2.The capacity

The units of elevator need and rated capacity is affected each other, should be reasonable collocation.

(1)The large capacity can reduce the number of lift,to save the construction area and elevator cost.While it will increase the probability of stop layer,cause a long time for passengers in and out of the car,and the average running time will also increased.

(2)The small capacity elevator used will need to increase the number of lifts,which occupy a large construction area and increase the elevator cost.But the average running time can be reduce,and we can fix the car size according to the rated capacity.

3.Related speed

Choose rated speed should be taken into account the traveling height and passenger flow and other factors.When the elevator stops short interval,it is not appropriate to increase the rated speed of the elevator.High speed elevator in the shorter stopping distance sometimes can not reach the rated speed.And the higher the speed of the elevator is, the greater of investment for security device needed.

4.Car cabin open and closing time

We should choose the correct way for door opening,the door opening width and the door machine speed performance.The width of the door should be selected according to the shaft width,car width and counterweight position and other elevator designs and factors.

Larger opening width will make the passengers in and out of the car smoothly.
