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.
