How much do you know about passenger elevator?

1. How does the elevator work?

The elevator has a car and a counterweight, which are connected by steel wire ropes, and the steel wire rope is dragged by the driving device to move the elevator car and the counterweight up and down on the guide rails in the elevator. Car elevator guidance system: The main function of the guidance system is to limit the freedom of movement of the car and the counterweight, so that the car and the counterweight can only move up and down along the guide rail. The guiding system is mainly composed of guide rail, guide shoe and guide rail frame.

2. Will the elevator wire rope break?

The steel wire rope (consisting of steel wire, rope core and grease) for elevators is dedicated to elevators. The country has special rules and requirements. The equipment of steel wire ropes is not only to support the elevator car and the additional load, but also consider the size of the traction force. Therefore, the tensile strength of steel wire ropes is much greater than the load capacity of elevators, and their safety factors are all above 12. Usually elevators are equipped with more than four steel wire ropes. Normally, the elevator wire ropes will not break together.

3.Is there a risk of a sudden power failure during elevator operation?

If the elevator encounters a sudden power failure or a fault in the power supply line during the operation of the elevator, the elevator will actively suspend the operation without any risk. Chuancai elevator has a car, which runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15". The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use the elevator regardless of its driving method. As the general term for vertical transportation vehicles in buildings. Since the elevator itself is equipped with electrical and mechanical safety equipment, once the power is cut off, the elevator brake will actively brake and make the elevator unable to run. In addition, if the power supply part has a planned power failure, it is Will tell, the elevator may be suspended early.

4. What's wrong with the sudden acceleration of elevator operation?

The elevator's operating speed, whether it is up or down, should run within the extra speed range of the rule. Usually, it will not exceed the speed. If it is overspeed, there is an anti-overspeed device in the elevator control system. Then the elevator will slow down or stop running.

5. Can the elevator car overload be controlled actively?

The load capacity of the elevator varies according to the needs. The elevator can only operate within the regulated load capacity. When it exceeds the specified load capacity, the elevator will actively alarm and cannot operate.

6. Will being caught when the elevator door is closed will damage people?

In the process of elevator closing, if the hall car door touches a person or object, the door will automatically open from the beginning without hurting people. Home elevators also have a stepped type with treads installed on the track to run continuously, commonly known as escalators or moving walks. A fixed lift equipment that serves a specified floor. The vertical elevator has a car that runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15". Due to the anti-pinch switch on the door, Once the door touches a person or object, this switch action makes the elevator unable to close the door and open from the beginning, and then close the door from the beginning. In addition, the closing force is regular and will not reach the level of injury.
