Elevator clearCommon senseHandbook
Is there a danger of a sudden blackout in the operation of the elevator
There is no danger that the elevator will automatically cease to operate as a result of a sudden power outage or failure of the power lines. As the elevator itself has electrical and mechanical safety devices, the brakes of the elevator automatically brake when power is out, rendering the elevator inoperable. In addition, any planned power outages in the electricity sector are notified in advance that the elevator can be stopped earlier。
What if the elevator suddenly accelerates
The speed of the elevator, whether up or down, shall be within the specified speed and shall not normally be excessive. In the case of speeding, there is an anti-velocity device within the elevator control system, which automatically works to slow down or stop the elevator。
Iii. Is the elevator car overload automatically controlled
The load weight of the elevator varies according to need, and the elevator can only operate within the specified load weight, and when it is exceeded, the elevator automatically alerts and cannot run。
Iv. Does it hurt to be caught in the elevator when it closes
The elevator is closed, and if a person or object is encountered in the hall, the door is automatically reopened without harm. Since there is a trap-protected switch on the door, once the door touches a person or object, the switch does not close the elevator, reopens it and then closes it again. In addition, there are rules for closing doors that do not cause injuries。
Can the elevator door be removed
The door of the elevator cannot be removed outside the hall and must be opened with a special tool (which is managed by maintenance staff). Passengers are not allowed to pick doors, let alone open doors, or run the risk of falling into the well。
Vi. What should be noticed when elevators suddenly lose power or malfunction and are trapped in cars
When held in a car, the person concerned may be contacted by means of an emergency alarm device (or a communications device), waiting for rescue or by beating the car door to draw the attention of the outside person. Do not pull the door or jump out of it so that there is no danger。
Vii. Is there a potential for suffocation in the lift cars
The lift carriages are ventilated into the wellway, the wellway is ventilated into the engine room, and the room is ventilated outside the building, without fear of suffocation if power is out. In many cases, the suffocation of passengers trapped in cars was caused by excessive tension. Therefore, in the case of being trapped, do not panic, and stay calm and patiently await rescue。
Viii. Matters to be noted when entering a car
When entering the car, if the elevator door is open, look at whether the elevator is on the floor, especially when the light is darker at night and the light is not clear. Care should be taken as to whether the car is on the floor, otherwise it is likely to cause harm and should enter and exit quickly, much less physically to block the door。
In case of fire, can you escape through the elevator
In case of fire, the passengers shall park the elevator on the floor where the fire or pyrotechnic fire has not spread, and the passengers shall refrain from using the elevator to escape from the stairs. Elevators with fire switches should press fire switches in a timely manner, and the elevators will automatically return to the base station to open and stop running and the passengers should escape immediately。
X. Elevator failure is frequent. Is the elevator safe
The elevator was designed with a variety of safety measures to eliminate the hazards of falling and hitting the top: the first is to monitor the state of the components of the equipment, which ceases to operate as soon as they do not work as required by the design. Examples include devices to prevent elevators from falling; security switches to monitor the normal functioning of electrical and mechanical components; locks to doors to doors to doors to doors to doors to doors to doors to doors to doors to doors to doors to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door to door, etc. When any security device is not working properly, the elevator will stop and, while it may be a inconvenience for the normal use of the elevator, it will prevent the danger posed by the disease。
Xi. Why is the maintenance elevator sometimes broken while running
Elevators, as highly intelligent equipment, have a direct impact on the reliable operation of elevators in terms of their overall design, component construction, installation and protection of the quality of the links. The failure of the elevator is not necessarily due to inadequate protection. Effective maintenance allows for timely and complete inspection of the condition of the equipment-related components and eliminates the risk of failure, but does not provide assurance that the elevator will not fail at all。
What if the elevator gets old
Elevators are products with a high degree of mechanical and electrical integration, and the quality of their manufacture, installation, maintenance, use of the environment and quality have an impact on the performance of the elevator, the failure rate and the duration of their use. While elevators meet safety standards at the end of their life cycle, their reliability is significantly reduced and their probability of failure increases. Elevators need to be evaluated as necessary and based on this assessment, they need to be repaired, modified or replaced. The costs of repairs, alterations, replacements are generally covered by the special maintenance funds for the property or shared by the elevator owners。
Why is there a failure in the approved elevator
The first is that elevators are frequently used mechanical equipment with an objective possibility of failure; the second is that they are subject to objective conditions such as social costs, testing resources and so forth. The state requires that they be tested strictly in accordance with the test projects prescribed by the rules of inspection, which are quantitatively limited and primarily reflect safety performance requirements, with fewer reliability requirements; and the third is that the reliability of elevators is generally closely related to product prices and maintenance costs, with low-cost elevators generally having a high rate of failure. This is somewhat similar to the distinction between high-end and low-end vehicles。
