Causes of malfunctions in the elevator system

The elevator malfunction may be due to the malfunction of its various parts, which will have different causes. In this section, we will discuss the common malfunctions in elevators and their causes.

Humidity: Any mechanical or electrical device exposed to moisture will fail. If elevators do not have a proper cooling and ventilation system, they will break down when exposed to the humidity of the outside air.

Increased temperature: The normal temperature of elevators should be around 5 to 40 degrees Celsius. But when the elevator does not have a suitable cooling system, its temperature reaches approximately 100 degrees Celsius, and this increase in temperature disrupts the operation of the elevator, and if it is not checked, it may cause the elevator motor to burn.
High energy consumption: This problem often occurs in old elevators.
The elevator suddenly stops and stops: This problem is due to a malfunction and defect in the elevator’s electrical system, meaning that the elevator’s electricity or part of it is cut off, and thus the elevator stops suddenly.
Wear and corrosion of the pull wire: If the location of the pull wire is not on the adjustment plate, it will cause the pull wire to wear and tear, reducing the safety of the elevator, and if it is not repaired, the elevator cabin may be exposed to corrosion and falls.
Fire: Sometimes poor quality or corrosion of the elevator electrical system leads to the wiring being connected, leading to a fire.
People getting trapped in the elevator: This problem can have many causes, including a city power outage, a power outage in the elevator, or people riding more than the elevator’s capacity.

All these problems can be solved by timely elevator service and maintenance, and if your elevator is maintained on time, many of these problems will not occur at all.

Request periodic inspection of the elevator

According to the July 2013 announcement of the Elevator and Escalator Union of Iran, for all elevators that have been in operation for three years, it is necessary for the selling company, which is a member of the union, to obtain a public service and elevator safety certificate through a separate contract. It is necessary to renew it every 3 years.

If owners, managers and users do not take serious action and cause physical, financial and life accidents, the legal responsibility for the accidents will be on them. This notice is considered a legal notice that can be cited in judicial authorities.

Types of elevator repair and service

Elevator repair and maintenance is one of the services that is performed after installing the elevator.

Elevators are devices for easy transportation of people and things in different parts of a building, and this device obtains the energy necessary for its movement through an electric motor.

Therefore, the elevator is considered an electrical device, and any electrical device that is used continuously requires maintenance.

There is also a possibility of breakdown of this type of equipment, so in general the need to repair and maintain elevators in buildings that contain elevators is necessary. Failure to repair and maintain the elevator on time can be a problem and also reduces the safety of the elevator.

So take this problem seriously and get expert help to repair and maintain your elevator.

Some of the most common elevator problems

In the previous section we mentioned the most common causes of elevator malfunctions, but now we want to check out the problems that can occur if the mentioned items are not followed;

Motor temperature increase,
if the pressure applied to the elevator motor is greater than its capacity, it will cause the motor to burn out.
As a result, when an electrical current higher than its capacity is used, it enters the motor and this causes the motor temperature to rise. If a half-burnt engine is not repaired in time, after some time it will burn out and fail completely.
The elevator motor is not running,
and in this case there is a possibility that the electrical circuit that powers the motor has a problem.
In such cases, the elevator service checks all the circuits and wires that pass through it to find out the cause of the malfunction.
The fuse operates during operation and causes the elevator motor to stop working.
The fuse is a small piece on the circuit of electrical appliances including the elevator, which if triggered will cut off the power input to the machine motor.
Sometimes this problem occurs in the elevator motor, which can have various causes, which can be fixed by repairing and maintaining the elevator.
The elevator gets stuck in the middle of the road or on the floors and stops moving.
This problem could be caused by a malfunction in the motor or elevator eye, and it must be checked.
The outer door of the elevator does not open,
and as you saw, all elevators have two doors; The main door of the elevator and the outer door connected to the floors are used for added security.
Sometimes the main door of the elevator opens, but the door gets stuck on the outside. This may be due to a malfunction in the lock or it is too far away from the door opener.
The speed of the elevator decreases due to the waiting time.
We may all face this problem, which is that even though the number of floors is small, we still have to wait for a long time for the elevator to reach the desired floor.
This problem mostly appears in worn and old elevators with a high year of manufacture. By changing and updating the circuit or elevator panel, this problem will most likely be solved.

The items mentioned were some of the most common elevator problems.

If your elevator is inspected by elevator repair and service technicians, the likelihood of these problems occurring will be reduced. If the elevator operator refuses to repair and maintain the elevator, other problems may arise.

Solutions to prevent elevator malfunctions

The problems that happen to the elevator are very simple in the beginning and their repair does not require a lot of money. But if the elevator is not repaired and maintained on time, this simple malfunction may cause a serious problem, which will definitely require a lot of money to repair.

At the beginning, this point must be pointed out: In buildings with a large number of units and generally in apartments where different people use the elevator, appoint someone to be the person in charge of the elevator. This person can be anyone and is only appointed to implement elevator failure prevention solutions and notify elevator repair and service companies in case of any problems.

But to avoid any problems related to the elevator, it is best to do the following solutions:

Inspect the elevator continuously;
Continuous inspection does not mean that you are constantly around the elevator and inspect it. It is sufficient that you inspect the elevator every day or at least several times a week.
The purpose of the inspection is to pay attention to whether the elevator buttons are working properly? Does the elevator door open and close easily? Is the elevator moving normally? And such external reviews.
If there is a problem, be sure to inform the experts;
Some people try to fix the elevator themselves when it breaks down. If the elevator is a complex device consisting of many parts, it is not everyone’s job to repair it.
Even experts have to be careful because a simple mistake can cause a serious problem.
Elevator repair and service companies have experts who are educated in this field and have sufficient knowledge and experience to repair and maintain elevators. So call these companies when you see the smallest problem.

Be careful when cleaning the elevator;
First, ask the experts how to clean the different bits and pieces, and then do it.

The last point is; Along with the elevator package, there is a manual like any other device, try to read the elevator manual and follow the tips mentioned in it so that your elevator has less malfunctions and has a long life.

If the manual is not available, you can ask your questions to elevator repair and service experts.

How to calculate the cost of installing an elevator in an apartment

To calculate the installation cost, you must follow the following steps:

First, you go to the relevant companies or their offices to request purchase or installation, and your specifications and requests are recorded by sales and installation experts.
In the next step, design and mapping experts indicate the required building and the necessary checks are carried out by them.
After technical inspections and other necessary checks, elevator design engineers begin design work.
After performing all the above steps, the financial group will calculate the purchase cost as well as the cost of installing this device for you.

In the previous steps, the design of the elevator was also mentioned. Some may ask: How is the installation cost alone calculated? In response to this question, it should be said that since elevator installation is an after-sales service, that is why the design, production and installation cost are calculated at the same time. But if you are just looking for information about the installation cost, you can contact our experts on site to find out all the exact costs.

Elevator service

In general, elevator service can be considered as a set of procedures related to visiting and inspecting all parts and components of the elevator, in which the performance of these parts is monitored and evaluated. The service process takes place where the service worker or skilled elevator technician comes to the place and uses the necessary tools and equipment to review and inspect the mechanical and electronic parts of the elevator system and repair them in the event of a malfunction or defect. Or replace those parts. Through these procedures, defective parts are repaired and accidents are prevented. It is best to maintain the elevator once a month and periodically, so that if a malfunction occurs and its parts break down, the necessary measures will be taken immediately.

Service and maintenance of all types of elevators

Elevator service and maintenance includes all types of elevator systems. Lifts are generally divided into traction, hydraulic, magnetic and hybrid types. Each of these elevators has its own mechanism and differs from each other in terms of generating and transmitting energy. The subject of elevator service and maintenance includes all types of elevators. Since the system and design of these types of elevators are different from each other, their service and maintenance are also different from each other and require special measures for it. But in general, it is necessary to service each of these types of elevators on a regular and regular basis every month.

Standard for elevator service and maintenance

The rules and standards for elevator service and maintenance must be followed. In fact, compliance with these standards can ensure optimal performance and system safety. We have discussed below the most important rules and standards required in elevator service and maintenance that must be followed. Regarding these standards, we must say that Hero Elevator, with its impressive history in this field, is committed to fully complying with these standards in order to maintain the trust and confidence of its employers and clients.

Elevator service and maintenance

Elevator service and maintenance includes services provided by the relevant companies and centers. In general, if we want to classify services related to elevator service and maintenance, the following three service categories are included:

Inspection and inspection: Service and maintenance of elevators is usually carried out monthly by companies and centers and during the contract concluded with them. The first category of these services is the visit and inspection of elevator systems. At certain intervals, which are usually monthly, service workers are sent to the place and inspect and monitor the entire elevator system to see if there is any damage or problem with the parts or parts.

Spare parts service: The second category of services related to elevator service and maintenance is spare parts service. This category of services relates to cleaning, jam removal, lubrication, noise removal, etc. Performing this type of service can significantly increase the useful life of the elevator and prevent potential breakdowns in the future.

Repairs: Sometimes during the inspection and visit of the machine by the working service, damaged and defective parts or parts are identified. Therefore, so that this malfunction does not spread to other parts and parts and does not cause failure of the entire elevator system, the labor service repairs the part. Sometimes repair is not possible due to excessive damage or burnt out of electrical parts and that part or parts must be replaced. In general, with timely service and identification of defective parts, it is possible to avoid incurring high costs by taking quick action to fix the defect.

Regarding elevator service and repair, we must say that Pars Elevator Company is one of the prominent and well-known companies that provides high-quality services in this field. This company, with its capable staff and modern equipment, has tried to achieve maximum customer satisfaction by providing quality services.

Elevator service and maintenance company

Many companies work in the field of elevator service and maintenance in cities, especially in Tehran. Depending on the experience they have and the availability of expert staff and necessary equipment, these companies service and maintain elevators in different capacities. In general, to perform these services you must register the elevator project specifications with one of these companies via phone calls, the Internet, etc., or a personal visit. Then the center’s experts are present at the location with a checklist to verify the technical condition of the elevator system and the health of the parts and components, and they diagnose the general condition of the elevator. Then, according to the expert’s estimate of the elevator system, the company adjusts and prepares the contract. After signing the company’s contract with the owner or owners of the building, the work service arrives at the site according to the regular monthly schedule and provides elevator service and maintenance services.

Elevator service and maintenance rules

The subject of elevator service and maintenance is subject to the laws that must be followed for this purpose. Below are the most important rules related to this issue. Knowing these laws will help building owners have the necessary knowledge when signing contracts so that they do not face serious problems later.

The duration of elevator service and maintenance contracts is one year, and the elevator is maintained once a month.
Building owners and employers must contract only with companies that are members of the Elevators and Escalators Syndicate and have a work permit from the Ministry of Industries. Therefore, one must refrain from concluding contracts with centers and companies that are not members of the union and do not have a specific office and a valid work permit.
Service fees are charged in the first year contract, in installments over 12 months. For the second year onwards, two equal installments of 6 months will be charged each year.
The employer or building manager is responsible for providing the necessary oil to service the elevator and providing it to serve the work.
All elevator systems must have a civil liability insurance policy for elevator owners against users, and the employer is required to pay the insurance premium for one year.
The cost of replacing or repairing parts and repair fees are separate and not part of the cost of service and maintenance, and must be paid separately by the employer.
During the period of time in which the employer concludes an elevator service and maintenance contract with the company, other persons, whether natural or legal, must not interfere in this work, and this work is prohibited.
The cost of the service contract is calculated based on 5 elevator stops. Other lifts that have 2, 3 and 4 stations are costed based on 5 stations.

Monthly elevator service and maintenance

As we mentioned, during the contract concluded between the employer and the elevator service and maintenance company, the company’s employees are required to visit the place regularly on specific days and visit and service the elevator system. The advantage of visiting and maintaining the elevator monthly is that while preventing malfunctions in other parts and even accidents and accidents caused by a malfunction of the elevator, it can also avoid incurring a lot of costs.

Regular elevator service

Regular elevator servicing includes all service-related services, which are performed regularly at certain time intervals, according to the checklist. In periodic service, the service worker is sent to the site by the contracting company at regular intervals and inspects and monitors various equipment and parts and repairs or replaces the defective parts if necessary. As well as cleaning the engine room, lubrication of rotating parts, etc. It is also part of the procedures that a soldier undertakes during his periodic visits. In general, the benefits of regular elevator service include the following:

The useful life of the elevator will be longer.
The efficiency of the elevator is increased and its performance is improved.
Defective parts and equipment are detected early. In this case, these parts can be repaired or replaced faster.
The possibility of life and financial accidents and mishaps is greatly reduced.
Since in regular service of the elevator, faulty parts are identified and repaired faster, in this case repair costs are significantly reduced.

Monthly elevator service

In the monthly elevator service, the worker comes on behalf of the contracting company to the place where the elevator is installed on a monthly basis and provides service and maintenance. The monthly service is considered a periodic service. In monthly service, it is possible to detect faulty parts and equipment early, facilitating the repair process. In this case, the safety of the elevator is significantly increased and various risks are prevented.

Regular elevator service fees

The cost of elevator service is determined every year by the Elevator and Escalator Association of Iran. In this case, under the contract, the employer must pay the cost of one year, which includes 12 months of periodic visits and service, to the contracting company. According to relevant regulations, the elevator service fee shall be paid in one installment of 12 months and two installments of six months each from the second year onwards. In general, the cost of elevator service depends on factors such as the group of buildings, the type of elevator, the number of floors of the building, the number of people using it, the amount of elevator traffic, the number of elevator stops, etc. Providing periodic services in periods of less than a month will also be subject to increased fees.

Elevator service and maintenance fees

Regarding the cost of elevator service and maintenance, we should say every year based on the building type, number of floors, cabin capacity, number of elevator stops, traffic, type and number of doors, etc. . The price of the service is determined by the union. In fact, the union is the official reference for determining the costs of these services. The employer can pay the cost of elevator service and maintenance according to the contract on an annual or monthly basis. Hero Elevators is one of the prominent companies that provides quality services to clients and employers for the relevant fees. This company is committed to providing high-quality maintenance and upkeep services so that the elevator system continues to operate for a long time without being exposed to serious malfunctions. This requirement is more economical for employers; Because they can use the elevator system for a long time and after a short period of time, they do not have to pay the costs of installing and operating the new system.

Important points for elevator maintenance

We have discussed below some important points that should be taken into account when maintaining the elevator. Considering these points can keep the elevator in proper condition in terms of safety and health. In fact, by following these tips, your elevator will never stop or get stuck between floors. Following these tips and proper maintenance can significantly increase the useful life of your elevator.

Recording of elevator operation

By recording and estimating elevator operation, you can recognize signs of potential failure in the elevator system and take quick action for potential repairs. Abnormal sounds such as squeaking can be a sign of malfunction, and you should record them and report them to the repair technician.

Try to check and visit the elevator every day.

Inspect and visit the elevator at the same time as recording its performance. Paying attention to the good working of elevator parts during inspection and visit is an important point.

Replace damaged parts or parts

If you are able to replace defective parts and parts that are not working properly. For example, if the lights inside the cabin are burned out, replace them. Of course, replace defective parts or parts if you are familiar with this task and strictly avoid arbitrary procedure.

Do not use synthetic detergents to clean elevator parts

It is recommended to never use synthetic detergents to wash and clean the elevator. Because there is a possibility of damage and corrosion to various parts of the elevator. According to experts, the most important cause of technical problems in elevators is the contact of elevator parts with industrial detergents that are used to clean elevators in buildings.

Using the elevator more than its capacity

You should always make sure to use the elevator according to its capacity, as using a larger capacity will put pressure on its mechanisms, which will eventually lead to damage, which will also cause serious risks to the residents.

Be careful when painting the elevator door

Be careful when painting elevator doors, as adhesive paints may cause the plastic door stops to become loose or even fall out. So do this with caution. For this reason, and for the best, cover the eyelids with a layer of Vaseline.

Controlling the safety and security of the elevator in the event of a fire

The possibility of emergency exit from the elevator in the event of a fire must be controlled and verified. Because in the event of any fire, the people in the cabin must have the possibility of emergency exit quickly.

Elevator engine compartment temperature control

Normally, the temperature of the elevator engine compartment should be around 15 to 32 degrees Celsius. If this temperature is higher or lower, act quickly to fix this problem.

Pay attention to the cleanliness of the elevator

It is necessary to pay special attention to cleaning the elevator and if the valves, doors, lamps, etc. are dirty. Clean it so that residents do not complain about this situation.

What does the elevator service include?

Regarding what the elevator service includes, we mentioned above in the elevator service and maintenance standards section. In fact, when a service is sent to the workplace and intends to service the system, it must do the things we mentioned above. It can be said that the elevator service standard is actually the things that should be considered during service. Generally, these items are included in the checklist that service workers carry with them at the time of service.
