Keep in mind the common problems of elevators and improve the safety factor of riding

In daily life, whether it is an escalator or a lifting elevator, some large or small accidents will occur. The editor will explain some common elevator safety knowledge in detail.

Common problem 1: Is there any danger of sudden power failure during elevator operation?

Sometimes, when we take the elevator, we will encounter a sudden power failure or failure of the power supply line. At this time, the elevator will automatically stop running, but there is no danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once there is a power failure, the brake will automatically brake, making the elevator unable to run. If the power supply department has a planned power outage, it will generally notify in advance to avoid accidents.

Common problem 2: Will the elevator wire rope break?

The steel wire ropes used in elevators are dedicated to elevators because the country has special regulations and requirements. The configuration of the elevator wire rope is not only to bear the elevator car and rated load, but also to take into account the traction force. The tensile strength of the wire rope is greater than the load capacity of the elevator, and elevators are equipped with more than four wire ropes.

Common problem 3: What should I do if the elevator suddenly speeds up?

Whether the elevator is running up or down, it should run within the specified rated speed range. Generally speaking, it will not exceed the speed. If overspeed occurs, there is an anti-overspeed device in the elevator control system, and the device will automatically act.

Common problem 4: Will it cause harm to people when the elevator door is closed?

When the elevator is closing the door, if the door touches a person or object, it will automatically reopen without injuring anyone. Because elevator doors are generally equipped with a type of device, once the door touches a person or object, the opening and closing action can make the elevator unable to close the door, and reopen it, and then close the door again. The closing force is prescribed and will not reach the level of injury.

Frequently Asked Question 5: Can the elevator door be opened?

The elevator hall door must be opened with special tools; passengers are not allowed to pick up the door when taking the elevator, let alone open it, otherwise there will be a risk of falling and a high risk factor.

Frequently Asked Question 6: What should be stated when the elevator alarms

If you encounter a dangerous or unexpected situation in the elevator, you should report to the police immediately. When you call the police, you should explain the specific situation of the elevator and the specific location of the elevator.
