We often hear that there will be some accidents when using elevators, so we need to pay attention to some related matters when choosing, buying and using elevators to ensure our safe use. Next, let's introduce some related problems about elevator classification and matters needing attention in elevator use. Let's have a look.

Elevator classification

Is the elevator car driven by electricity running vertically or inclining to the vertical direction not more than 15? Equipment for transporting people or things between two rows of rigid guide rails.

The classification of elevators is very complicated, and there are different classification methods:

1, classified according to the international standard ISO 4 190/ 1.

(1) Class I: Passenger elevators (including residential elevators for apartments) are referred to as passenger elevators for short.

(2) Class II: Passenger and freight elevators.

(3) Category III: sickbed elevator.

(4) Class IV: service elevator (also called sundries elevator).

2. Classification by purpose

(1) Passenger elevator: an elevator designed to transport passengers. Suitable for airports, restaurants, hotels, office buildings, large shopping malls and other occasions with large passenger flow. In order to improve the transportation efficiency, this elevator has the advantages of fast running speed, high degree of automation, complete safety facilities and beautiful decoration.

(2) Freight elevator: an elevator designed for transporting goods, usually accompanied by someone. Mainly used in workshops with more than two floors and various warehouses. The decoration of this kind of elevator is not very particular, and the degree of automation and running speed are generally low, while the load and car size vary widely.

(3) sickbed elevator: the elevator used to transport sickbeds in hospitals has a narrow and deep car.

(4) Miscellaneous elevators (service elevators): elevators for transporting books, documents and food in libraries, office buildings and restaurants. No one is allowed in. This elevator has incomplete safety facilities and is not allowed to carry passengers. In order to prevent people from entering the car, the door opening and the area of the car are designed to be very small, and the clear height of the car generally does not exceed1.2m. 。

(5) Sightseeing elevator: the elevator with transparent car wall is used for sightseeing by passengers.

(6) Special elevator: In addition to the above-mentioned common elevators, there are elevators designed for special environment, special conditions and special requirements. Such as marine elevators, engineering elevators, explosion-proof elevator, anti-corrosion elevators, car elevators, mine elevators and so on.

3, according to the speed classification

There is no strict speed classification for elevators. China's habit is this:

(1) Low-speed elevator: the elevator whose speed is lower than1.0m/s.

(2) Medium-speed elevator: elevator with speed of1.0 ~ 2.0m/s.

(3) High-speed elevator: an elevator with a speed greater than 2.0m/s. ..

(4) Ultra-high-speed elevator: an elevator with a speed exceeding 5.0m/s. ..

With the expansion and improvement of elevator speed series, the speed limit for distinguishing high, medium and low speed elevators has also increased accordingly.

What are the precautions for elevator use?

The elevator is used to go upstairs or downstairs to take people upstairs or downstairs;

1, the elevator is generally at one end of the corridor, with a deep door frame and a silver-gray stainless steel door;

2. When there are multiple elevators on the floor, there will be single-deck elevators and double-deck elevators, and the floor number is affixed on the door eyebrow, so you can choose the elevator according to the floor number you want to go to;

3. On the wall next to the stair door, there is a round button for going upstairs or downstairs, with a triangle pointing inside;

After pressing one of the buttons, the indicator light inside will light up, indicating that you want to go upstairs or downstairs from the current station.

At this time, stand outside the door and wait for the elevator to come. Be careful not to stand on the elevator threshold. The button has the direction and floor of elevator operation;

6. The elevator will open at the door. If the direction is your own, you can go in. Be careful to get off before getting on the bus. Let out what comes out first.

7. There is a row of buttons beside the right door of the elevator. After entering, press the floor you want to go to, and then find a place to stand;

8. Above the button, it shows which floor the elevator is running on. At the bottom, there are two buttons to open and close the door. The elevator won't leave until the door closes.

9. After the door is closed, the elevator will start to move. When it reaches the floor, it will stop and open. Don't worry too much about noticing your own floor.

The above is about the classification of elevators and matters needing attention in elevator use. I believe you should know something about the classification and use of elevators. In our life, the use of elevators is inseparable, so now there are more and more types of elevators, and different types of elevators are selected for different occasions. Of course, in the process of using the elevator, we should also pay attention to some matters to ensure our safety.
