Maintenance and Repair - Frequently Asked Questions

1. Why can't you use the elevator to evacuate during a fire or earthquake?
   In response to fire and earthquakes, firefighting operations will be carried out, so the power supply will be cut off and water will be sprinkled, which may cause " "Guarantee people".
   And the earthquake may cause the guide rails to deform, making the elevator unable to operate normally, so the elevator cannot be used for evacuation.
   
   
2. If there is a power outage while riding in the elevator, will it “concern” people?
   If the building does not have its own backup power supply, it will "lock people out." However, if the elevator is equipped with an "automatic landing device during power outage", during a power outage, the elevator can use battery power to move the carriage to the nearest floor, and passengers can leave the carriage.
   
   
3. What are the safety standards for elevator wire ropes? If it breaks, will the elevator fall?
   Elevators vary in size and specification and use multiple steel cables to hang the carriages. The National Standard of the Republic of China (CNS) stipulates that the safety factor of the steel cable should be greater than 10, which means that the withstand capacity of each steel cable must be greater than 10 times the specified load. If the elevator has been regularly maintained by a professional manufacturer, the safety factor of the steel cable must be determined If the quality is normal and there is no rust, broken wires, bends, etc., there is no need to worry about the wire rope breaking.
   
   Modern elevators are equipped with comprehensive safety measures. Even if the elevator descends at an abnormal speed, it will detect whether the elevator is descending at an abnormal speed. The abnormal "speed regulator" will operate and first cut off the safety circuit to stop the main engine. If the speed does not slow down, the mechanical principle will be used to activate the "emergency stop device" under the car to clamp the track to prevent the elevator from falling.
   
   
4. How often does the elevator need maintenance? Are there any legal provisions?
   General elevators are based on the provisions of Article 4 of the "Measures for the Installation and Inspection of Building Lifting Equipment", "Managers Professional manufacturers should be appointed to be responsible for the maintenance of lifting equipment...implement it on a monthly basis and prepare a record sheet..." Therefore, maintenance should be carried out regularly every month to ensure the safety of the equipment.
   
   As for elevators used in personal residences, according to the "Construction Management Letter No. 58591 of the Construction Administration of the Ministry of the Interior" Explain, "...the use and maintenance of equipment should be regulated by the contract between the user and the equipment manufacturer...". Therefore, it is recommended to entrust a professional manufacturer to develop the most suitable maintenance plan based on the elevator usage conditions.
   
   
5. How is the number of passengers in an elevator calculated?
   is calculated based on the floor area of the carriage, and the calculation formula is based on the 20th "Construction Standard for Elevator Safety Inspection" Nine regulations.
   
   
6. What types of elevators are there?
   Passenger Elevator
   Freight Elevator
   Passenger and Freight Elevator
   Bed or Hospital Elevator
   Car Elevator
   
   
7. What are the common opening and closing methods of elevator doors?
   CO: 2 doors opening in the middle.
   2CO: 4 doors opening in the middle. Commonly found on freight elevators.
   2S: 2-piece door opens on the side, opening on the left and right.
   3S: 3-piece door opens on the side, opening on the left and right. Commonly found on freight elevators.
   2U: 2-piece door opening. Commonly found in freight elevators or car elevators.
   
   

8. How are elevator types and specifications expressed?
   Using the company's presentation method to explain, the format is "Elevator type - accumulated load - door opening Method - lifting speed - number of stopping floors (number of floors)"

   Take the passenger elevator as an example: P15-CO-105-10S/O (1-10F)
   ①Elevator type code: P (for passengers), F (for cargo), S (for people) (dual use), B (for hospital beds), F (for automobiles)
   ②Storage load: 15 people
   ③Door opening method: 2 doors opening in the middle
   ④Lifting speed: 105m/min
   ⑤Number of stopping floors: 10
   ⑥Number of floors: 1-10F
   
   

9. Why are elevators equipped with mirrors?
   If it is a barrier-free elevator, it is based on the provisions of Article 406.3 of the "Design Code for Barrier-free Facilities in Buildings". "A safety glass rearview mirror should be installed on the rear side wall facing the cabin (this is omitted if the rear side wall is made of mirror stainless steel or similar material)..." and installed.
   If it is a general elevator, it is installed according to the needs of the manager.
   
   

10. If you are locked in an elevator due to a breakdown, will you suffer from hypoxia?
    The space in the carriage is not completely enclosed, so there is no concern of suffocation when trapped due to a malfunction.
    However, passengers should immediately press the "Emergency Call" button to contact the security personnel. And wait for rescue. Never get out of trouble on your own to avoid danger!
    
    

11. What should you pay attention to first when entering the car?
    Please confirm that the bed in the carriage has indeed been installed in the correct position, and do not rush to board to avoid accidents. Please also pay attention to elevator etiquette: first in, first out. And give courtesy to those who need it more.
    
    
12. Why are there elevator orphans?
    ─Entrusting non-original factory maintenance not only lacks professional skills, but also for old models, Problems such as the discontinuation of parts areunable to respond, which makes the elevator maintenance work incomplete and becomes a problem. Elevator Orphan.
    ─Buying an assembled elevator from a retail store often goes bankrupt due to poor management, leaving no recourse for elevator maintenance.
    ─Entrust non-original maintenance to non-original factory maintenance. When the elevator fails, it is often ignored due to insufficient technology and inability to respond. This will cause consumers to suffer greater losses.
    
    
13. Why do elevators always break down?
    ─Unstable voltage will cause the elevator to run incorrectly and may cause elevator failure over time.
    ─ Frequent use of the elevator to carry goods overloaded or abnormal operation may easily cause elevator failure.
    ─When cleaning the floor, water accidentally seeps into the gaps in the elevator, which can easily cause short circuits and malfunctions in the elevator. .
    ─ Poor access control in the building allows unauthorized persons to enter the computer room, damage equipment or steal parts, which may also cause ElevatorFault.
    ─There is dust or debris in the elevator threshold groove, which may cause the elevator door to fail to open normally. ,closure.
