Latest data and review of the European lift

The following data according to the European Elevator Association ELA (Lift Association European) website published by the contents of finishing.

There are 58.5 million lifts in Europe.

127,000 new lifts increased every year.

154000 elevator employees in elevator companies.

More than 1 billion users per day.

In the ISO assembly has just mastered the number of the United States Elevator 1 million 780 thousand till 2015.While I personally feel that the United States did not have so many elevators,I have seen on the Internet a bullish data is that the lift number is about 900 thousand in USA.

The chairman of ISO/TC 178 Mas Latrie De introduced that:There are 925 thousand units new elevators increased every year global.Which the largest increasing area of the elevator is the Asia Pacific Region.

Currently in the world with more than 15 million elevators, the annual increase in the elevator cost and maintenance services market price of more than $65 billion.

There are 58.5 million lifts in Europe.

127,000 new lifts increased every year.

And china elevators are 4 million 259 thousand at the end of 2015, with new lift slightly over 660 thousand increased.

Europe, China, the United States, the elevator numbers of these three area are near  80% in the total number.Just in china,the increased elevator equipment 

every year is 71.5% in the global increase numbers.

Therefore, the impact of the new elevator standards for China is the largest, we should play a greater role in the field!

Elevator type selection

With more and more buildings equipped with elevator equipment,the investor and designers will meet such problem:How to choose the elevator for your project? Now we combined some technical problems with the elevator to talk about some of the key points should be paid attention to for elevator type and also elevator design selection.

1.Main parameters to determine the transport capacity

The elevator numbers,capacity and rated speed.

The elevator should have proper transportation capacity which should meet the 5 minutes peak demand.And the time interval should not be too long for the elevator to arrive in the hall,normally can not over 2-3 minutes.

2.Need to focus on the technical performance

(1)The reliability,advanced nature and comfortable

The reliability is the ability of the elevator system to maintain the specified function within the specified time.

The request of reliability refers to the failure to do as little as possible in the run time.

Especially for the safety gear,speed governor,security touch panel, grating gate area protection system, etc. to absolutely can not fail.

(2)The advanced nature of the elevator is mainly reflected in the drive and control technology.

Vector control of the frequency modulation technology (VVVF) to make the AC induction motor speed control performance reached the level of DC motor.

Our elevator manufacturer Aolida having such advanced technology from German and Automatic producing line with imported machines.

(3)Comfort mainly refers to lift acceleration, vibration, noise, decoration, lighting and other indicators.The purpose is to provide a passenger with a comfortable environment.

It is obvious that reliability is the most important index in elevator selection.It is pointed out in GB10058 statement:Elevator operation 60 thousand times less than 5 times the failure of qualified products;failure less than 2 is the first grade and less than 1 times for excellence products.All of the elevators produced by Aolida elevator china is the first grade.

3.Drag control mode: AC double speed, voltage regulation and speed regulation

The elevator speed is zero when the elevator stops, and the normal operation is to make a straight line motion at a rated speed.

Low speed elevator often uses the two speed program(AC-2),with less control links,low probability of failure. The main disadvantage is the leveling accuracy and ride comfort is difficult to be reconciled.

Medium speed elevator using adjustable speed and voltage control (ACVV) technology.In the recent ten years, the new technology of frequency modulation (VVVF) has been developed.
