Elevator installation

The elevator is a kind of electric motor driven vertical lift, with box shaped car cabin for multistory buildings taking passengers or carrying goods.Which is well known passenger elevator and freight elevator.There are steps type, step plate installed in continuous operation of the track, commonly known as the escalator or moving walk.Service to the fixed floor of the fixed lifting equipment.And vertical elevator equipment having a car cabin,and run in at least two columns of a vertical or inclined angle less than 15 degrees between the rigid guide rail.

Now let’s see the elevator installation steps and methods.

1.Elevator installation method

According to the actual situation, we use the construction site crane installation method.That will lift the crane base, the first three sections of the standard section,basic fence, cage, driving plate installation, then adding installation, until it reaches the height.

2.Elevator installation steps

(1)Installation of foundation frame (base).

Use the level of instrument (ruler) leveling standard interface, and fill the gap between the base frame and the infill, and then tighten the anchor bolts.

(2)Bottom three section guide rail installation.

(3)Car cabin installation.

After the installation the six buffer spring on the framework ,use tower crane to lift the cage, slowly in place on the standard section, placed in the buffer spring.

(4)Installation of driving device.

Construction elevator installation notes:

1.The Installation personnel of the elevator construction must be approved by the special safety training, examination of qualified certificates.

2.The operator must be familiar with the performance of the operation of the elevator, construction, maintenance knowledge.

3.Construction of the elevator around 5m, shall not be stacked flammable items and other debris.Not in the range of trenching, pits, grooves. The inlet should lift the ground erection protective shed.

4.It is strictly prohibited to use derrick construction elevator horizontal pulling cable support and other slogans and lift irrelevant articles.

5.The same site construction of tower crane or other lifting machinery shall be away from the construction of the elevator 5m above, and shall have reliable collision avoidance measures.

6.After the construction of the elevator installation, must be inspected and accepted by the relevant personnel then to be put into use.

Elevator and city life

Twenty or thirty years ago, the city began to expand from the land of China, people have not been accustomed to the existence of the elevator.An old man was brought to the city from the countryside by his children,all the villagers asked the old man almost joking when he back:Is the city curious? He said:Anything else, that's what it's called the elevator. It's really interesting.As the door opened and closed, all changed as a magic trick.

While Now, for the elevator, people have never been accustomed to regard it as an ideal of course, there is a kind of existence.

The city needs the elevator, as Kafka said, "a bird looking for a cage".The functionality elevator equipment is so strong that it lacks poetic items, like a vertical submarine hidden in the building.With a small space load in the crowd, quietly walking in reinforced concrete.This cage inspires people to imagine that. At the beginning, it needs a full time driver to operate and make great efforts efforts to decorate in the external.With the development of technology, the transparent glass is added to reduce the fear of the people.

It is a silence in the passenger elevator,If you are ready to talk, natural blockbuster.

When you are together with a boss, a colleague or a client,In twenty or thirty seconds, is to smile and nod, or speak with jest to defuse the silence?This is a same embarrassing problem if meeting with the men's toilet.So those who are committed to the success of the training division found that this major business opportunities.

The great concept of "elevator speech" was invented.Teach people how to speak in this twenty or thirty seconds, in order make customers or leaders have a pleasant impression.

It can be said that the elevator is one of the best places to describe the spirit of the modern city.

In the hit series "mad men", the Madison street in 1960s in New York as the background of the story, almost every episode appears to be a lift play.The editor of the Wall Street journal also had a chat with the screenwriter, executive producer Matthew Wiener.Wiener said,so much of the elevator scene is because the elevator is a private matter can occur in public space.Elevator movements metaphor the characters in the rise and fall of the cause and the sense of being.It took us modern people daily simulation fly up to the clouds, falling into the abyss.Suddenly give birth to look forward to, suddenly determined.

So the elevator companies now are paying more attention to the elevator designs.

Since Modern city life has been unable to leave the elevator.It is no longer just a simple means of transport, it is also a very important place to live.Is a special living space, into the life of the interpretation of life.

Dumbwaiter introduction and maintenance

Now the common elevators as "passenger elevator", "escalator", "lift" these people often use in daily life.And dumbwaiter is rare to see since the usage of dumbwaiter is not so much as elevator.Generally speaking,dumbwaiter is used in the restaurant,hotel and the library for transport food or debris.

Today let’s see the details introduction of dumbwaiter and maintenance method.

Introduction to the knowledge of the elevator

Dumbwaiter elevator, with small size, complete function, stable transport but low price.It is widely used in the dining hall and the transportation of the food and the factory, the library and so on.

Compare to the common elevators,dumbwaiter have less volume while the function is more or less.It is also run smoothly and stable,but the dumbwaiter elevator cost is much lower.

Now in the market,there are two types of dumbwaiters according to the use methods and working methods.But now people on the installation of the framework, because it is more convenient.

The wide use of the dumbwaiter, occasions throughout the school canteen, hotels, restaurants, libraries, etc.In china,the <Safety Specification for manufacture and installation of dumbwaiters> state that,the capacity of dumbwaiter elevator can not

Be lager than 300kg.

Performance advantages of dumbwaiter 

The elevator adopts advanced microcomputer control system, to ensure that the instruction is fast, accurate and reliable.

The Lift standard manual can open the door and guarantee the maximum millimeter accuracy level.

Elevator design use the hairline stainless steel type control panel, seven digital display, elevator button.

The advantages of the civil engineering: the elevator shaft is above the engine room, the drive part and the control panel are directly placed in the well path.

Maintenance of dumbwaiter 

Although the use of the dumbwaiter is not as wide as the elevator, but in a certain sense, it is also a kind of elevator.

Attention to its maintenance can increase the use of the elevator to extend its service life.So let’s make up for you to introduce some of the maintenance of the dumbwaiters.

1.First of all, in the use of the course of the elevator must pay attention to its load, pay attention to not exceed the approved load capacity.And the carrying of the goods to be placed in the middle of the elevator car as far as possible, so that the force of the elevator can be guaranteed to be uniform, and can avoid the appearance of the car stuck in the car.

2.Second, after the transport of goods to ensure that the door can be closed, so as to ensure the normal use of other floors.

3.Third,when cleaning the steel wire rope of the elevator, we must pay attention to it can not be cleaned directly by hand.But to use some tools to scrub, generally use the long handle brush tool.

4.In the end, when press the button of the elevator, be sure to pay attention to its strength, so as to avoid unnecessary damage.And in cleaning up the control panel of the elevator, we must ensure that the elevator is in the overall power of the state, so as to avoid the accident of electric shock.

3 inevitable trend of the future development of the elevator

Integration of elevator control system

Elevator automatic control system has become a branch of computer technology application in the field of a very dynamic.In order to adapt to the high request of  the system security,

reliability and function implementation flexibility, the developed system is taking the microcomputer as the core.This elevator control system is using the 4C technology, which is, computer technology (COMPUTER), automatic control technology (CONTROL), communication technology (COMMUNICATION) and conversion technology (CHANGE) into a highly related and integrated system.

It has an obvious superiority then the previous control system on adaptability, extensibility, maintainability, system stability, and so on.Now the new control system has become the cornerstone of the development of elevator control technology.

Elevator speed tends to be super high speed

With the rise of skyscrapers buildings, the running speed of the elevator is challenging, but also to promote the development of the elevator technology.

Currently the world's highest speed of the passenger elevator has reached 17m/s,
more than 18m/s elevator china will run in the more than and 600 meter high Shanghai Center Tower.

It can be expected that, with the development of multi purpose, full function of super high rise buildings,Ultra high speed elevator will continue to be the direction of research and development.

Large capacity of traction motor, high performance microprocessor, vibration, noise suppression technology, automatic pressure regulating system in the car, which is suitable for the ultra high speed elevator safety parts technology will actively promote.

The popularity of green elevator is an inevitable trend

 

The application of energy saving, environmental protection material in the elevator design and elevator parts has been created.Gear-less permanent magnet synchronous traction machine, energy feedback device is rapidly improving the matching rate.

The car walls,guide wheels and traction wheels are made of non-metal materials have been put into application.

The elevator suspension system use flat steel composite traction wire rope instead

the traditional steel wire rope traction.Especially use the non-metal traction wire rope to make replacement.

Two twin elevators sharing the same shaft space have already started to run.And the elevator group control system is more intelligent.

With the development of intelligent buildings, intelligent control system of elevator equipment can be combined with the building automation of all service equipment into a whole intelligent system.

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.
