2019 ultra-professional elevator safety science popular video, take a look!

2019年超專業(yè)的電梯安全科普視頻,都來看看!

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.

1

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.

2

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)

3

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!
