2019 ultra-professional elevator safety science popular video, take a look!
This was taken with a paper clipA great set of popular science videos about elevator knowledge.
There are also individual details on the elevator
Made a few minor corrections, as follows:
Web Comment: Very good video, as an elevator industry practitioner, basically found no errors. In the spirit of the whale, I picked the following small flaws.
The card slot at 0:54 is called the guide shoe. Here the guide shoes are sliding guide shoes, and the high-speed elevator uses rolling guide shoes.
At 1:48 of the video, the requirements for the elevator wire rope strength GB7588 elevator manufacturing and installation safety requirements given in 9.2.2 are: three or more safety factors are 12; two safety factors are 16 (see the standard for the definition of safety factors)
Now the former Quality and Technical Supervision Bureau has been merged into the Market Supervision Administration.
Popularize elevator safety knowledge and forward it for more people to see!
