The door switch button and the floor button failure

Core reminder: The Freight Elevators of elevators is increasing with the height of floors, the frequency of use is increasing, the wear and tear is increasing, and the number of elevator accidents is increasing. In addition to normal maintenance and repair, in fact, the number of elevators is increasing with the height of floors, the frequency of use is increasing, the wear and tear is increasing, and the number of elevator accidents is increasing. In addition to normal maintenance and overhaul, in fact, there will be signs as an early warning before an elevator accident, so what are the warning signs for elevators? 1.

Possible reasons: A. The traction sheave does not match the wire rope. B. The traction condition design is unreasonable and the specific pressure is insufficient. C. The rope tension is uneven. It can be divided into two types: public transportation type and commercial type: (1) Public transportation type: It is an integral part of the public transportation system. It can adapt to a weekly operating time of about 140h and a continuous reload time of no less than 0.5 in any 3h interval. h, escalators and moving walkways whose load should reach 100% braking load. (2) Commercial type: Escalators and moving walkways other than public transportation are generally called commercial types.

Jitter phenomenon (elevator shakes left and right, vertical vertical jump, resonance with sound, etc.) (1) Jitter in elevator quality (2) Jitter in poor installation of elevator (3) Jitter caused by improper commissioning of elevator Floor phenomenon (from the designated floor to below the designated floor) 3. Lifting of the elevator (from the designated floor to above the designated floor to the top) 4. The sinking phenomenon of the car (the bottom of the car and the floor are not on the same plane, Lower than the height of the floor) 5. Button failure (the door switch button and the floor button failure)

Generally, the elevator will have a corresponding phenomenon before the accident as a symptom warning. We only pay attention to it when we use it normally. Once problems are found, Relevant personnel should be notified immediately for maintenance. Don't feel that you have just left when you reach your destination safely, this is likely to cause a serious elevator accident. Therefore, the maintenance of the elevator depends on everyone's strength, so that our lives can be fundamentally guaranteed.
