Why are elevators limited to 15 passengers

The simplest thing is that the space of the elevator is so large, how many people do you want to install, he is not limited to the number of people, but to the weight.

The relationship between the load of the elevator and the number of people.

According to the provisions of the international standard GB7588-1995, the number of passengers shall be obtained by the following method:

Calculated according to the formula (rated load capacity of 75kg), the result is rounded down to the nearest whole number.

For example: 1000 kg load, calculated according to the formula 1000 75=, rounded down to 13 people; So the number of passengers in a 1000 kg elevator is 13. Some elevator companies, because the unit of calculation is 65kg (this is the Japanese standard), the number of passengers marked on them will be larger than the normal value, so do not mistake the passenger capacity of these companies' elevators is greater than that of other companies.

The number of people is also related to the area of the car, and the following table shows the relationship between the number of people and the minimum effective area.

The table depends on the references.

It's not the number of people that is limited, it's the weight. Being overweight is dangerous.

Depending on the design of the elevator, the mechanical connection strength of the wire rope, as well as the balance coefficient between the counterweight and the elevator car, and of course, the power of the motor. When these conditions are set, the elevator will have a rated load and rated speed.

If you have any questions about the elevator, please feel free to contact me.

There is a limit to everything, and if it is exceeded, it will be *** or even dangerous.

To put it simply, the elevator relies on the motor to pull the steel rope up, and the rope will break if it is too heavy, which is unsafe.

The elevator has a rated load capacity! Just to the 4th floor!

Being overweight can damage the machine, and in the worst case, it will fall

In weightlessness, you don't have to think about how many people you can load! Elephants can fit hehe!

Big brother, do you still need to ask, one steamed bun can be full, you want to eat ten, what do you say?

I want to know how to find you on the 3rd floor.

The manned elevator was originally used to install passengers up and down, is there any problem?

When it runs, the passengers will serve the passengers.

Well, elevators classified according to their operating speed can be divided into:

There is no strict speed classification of elevators, and it is customary in China to classify them according to the following methods.

Low-speed elevators often refer to elevators that are lower than speed.

Medium-speed elevators often refer to elevators with speeds.

High-speed elevators often refer to elevators with greater speeds.

Ultra-high-speed elevators, elevators that exceed the speed.

With the continuous development of elevator technology, the elevator speed is getting higher and higher, and the speed limit that distinguishes high, medium and low-speed elevators is also increasing accordingly.

The number of passenger elevators in the hotel shall be determined according to the star rating of the hotel, the building plan, the number of floors, the area of each floor, the number of people, and the technical parameters of the elevator to be selected (such as running speed).

1.In order to accurately, reasonably and economically determine the number, load capacity and speed of elevators, the total number of people in the district, the maximum number of passengers served within a limited time during the peak period of the elevator, the waiting time of passengers or the full travel time of the elevator from the time of the elevator to the arrival of the elevator should be calculated.

2.The number of passenger elevators in the hotel and the main technical parameters are referenced.

3.Elevator speed is divided into low speed; Medium speed; High speed 5m s; Ultra-high speed 6 10m s.

4.Hotel passenger elevators are generally 6 15 floors, using medium-speed elevators; 15 25 floors above the use of medium-speed elevators.

According to the passenger flow and elevator load and speed to calculate, but also related to your floor height, it is recommended to ask you to consult the elevator sales related departments, consultation should be free, and more accurate.

1. Pay attention to overrun and overload.

The elevator can not be overloaded, when the elevator alarm, you should take the initiative to exit, wait for the next trip and then ride, the elevator overload is very dangerous.

2. Do not block the elevator door.

When the elevator door is about to close, do not force the elevator to rush into the elevator, prevent the elevator from closing, and do not stay with one foot inside and one foot outside, which will be hurt.

3. Don't press the panic button casually.

The panic button is set up to deal with unexpected situations, and when the elevator is operating normally, do not press the panic button, otherwise it will bring you unnecessary trouble.

Fourth, do not open the door to run.

When taking the elevator, if the elevator door is not closed and it runs, it means that the elevator is faulty, and passengers should not take it, and at the same time report it to the maintenance personnel.

5. Do not take the elevator under maintenance.

Before coming to the elevator, passengers first look to see if there is a "stop the elevator maintenance" sign. If the elevator is under maintenance, it should be hung with such a sign and passengers should not take it.

6. Do not take the elevator in case of fire.

In the event of a fire, the driver or passenger should stop the elevator on the floor where the fire or smoke has not spread, and passengers are not allowed to use the elevator to escape, but to escape from the safety exit of the staircase.

7. Don't panic in case of accidents.

In case of failure during the operation of the elevator, passengers should not panic, should press the intercom or alarm bell button to notify the maintenance personnel to rescue, do not mess with the press, waiting is a wise choice to ensure safety.

8. Observe when entering and exiting the elevator.

After the elevator stops, passengers should pay attention to observe whether the elevator car floor and floor are level when entering and exiting the elevator, if it is uneven, it means that the elevator is faulty, and should be notified in time to ensure the safety of passengers.

Instructions for safe elevator riding.

In order to ensure the personal safety of passengers and the normal operation of elevator equipment, please follow the following regulations to use the elevator correctly.

1. It is forbidden to carry flammable, explosive or corrosive dangerous goods on the elevator.

2. Do not shake left and right in the car when taking the elevator.

3. It is forbidden to smoke in the car to avoid disasters.

4. When passengers are trapped in the car due to power failure, failure and other reasons, passengers should remain calm and contact the elevator management personnel in time.

5. When passengers are trapped in the car, it is strictly forbidden to forcibly open the car door to prevent personal shearing or falling accidents.

6. If a passenger finds that the elevator is running abnormally, he or she should immediately stop using it and notify the maintenance personnel to come for inspection and repair.

7. Pay attention to the load when taking the passenger elevator, and automatically reduce the number of people if overload occurs, so as to avoid danger due to overload.

8. When the elevator door is about to close, do not force yourself into the elevator and do not stand with your back against the hall car door.

10. Do not turn your back to the car door after entering the elevator to prevent falling when the door is opened, and do not step back out of the elevator. When entering and exiting the elevator, pay attention to whether it is level.

Ten. 1. Elevator passengers should abide by the instructions, follow the arrangements of the elevator service personnel, and use the elevator correctly.

Ten. 2. Preschool children and other persons who lack the capacity for civil conduct to take the elevator shall be accompanied by a healthy adult.

International standard, 75kg per person, Small Japanese standard: 65kg per person, rounded down, 18 or 21 people.

By the way, I would like to sigh about the national situation in Japan.

In the "Rules for Installation, Transformation and Maintenance Licensing of Mechanical and Electrical Special Equipment".

Classification and grading. Class A technical parameters are not limited.

Class A can manufacture, install, maintain, and transform elevators, Class B can install, maintain, and transform elevators, and Class C can install and maintain elevators. According to the different purposes of use, it is divided into passenger elevators and freight elevators. According to the elevator shape, it is divided into machine room and machine room; According to the running speed, it is divided into lower and lower speed ladders or above high speed ladders.

Whether it is a passenger elevator or a freight elevator, its structure is the same. The composition of the passenger elevator is divided into eight parts, which are described as follows:

Traction system: The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of a traction machine, a traction wire rope, a guide wheel and an anti-rope wheel.

Guiding system: The main function of the guiding system is to limit the freedom of movement of the car and the counterweight, so that the car and the counterweight can only be lifted and lowered along the guide rail. The guide system is mainly composed of guide rails, guide shoes and guide rail frames.

Car: The car is an elevator component that transports passengers and goods, and is the working part of the elevator. The car is composed of a car frame and a car body.

Door system: The main function of the door system is to seal the entrance to the landing and the entrance to the car. The door system consists of a car door, a landing door, a door opener, and a door lock device. Weight Balance System:

The main function of the system is to balance the weight of the car relatively, and to keep the weight difference between the car and the counterweight within the limit in the elevator work, so as to ensure the normal traction transmission of the elevator. The system is mainly composed of counterweight and weight compensation devices.

Electric Drag System:

The function of the electric drive system is to provide power and implement elevator speed control. The electric traction system is composed of a traction motor, a power supply system, a speed feedback device, a motor speed regulating device, etc.

Electrical control system:

The main function of the electrical control system is to operate and control the operation of the elevator. The electrical control system is mainly composed of a control device, a position display device, a control panel (cabinet), a leveling device, a layer selector, etc.

Security protection system:

Ensure the safe use of elevators and prevent all accidents that endanger personal safety. It is composed of a speed limiter, a safety gear, a buffer, and an end station protection device.

High Efficiency Vector VVVF Inverter System:

The passenger elevator adopts a vector-controlled digital closed-loop VVVF inverter, which can accurately control the rotating torque of the main engine in real time according to the actual load of the car, up and down speed, and through the adjustment of the current size and phase, so as to ensure the smooth operation of the elevator.
