Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof, and heat-resistant elevators
As elevator people, escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator.

Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator, we must stand firmly and support it well, and do not lean against the skirt board on the side of the escalator.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
The elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.

The area of the independent fire elevator front room is: the front room area of the residential building is greater than 5 square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than 6 square meters. When the front room of the fire elevator is shared with the smoke proof staircase its area is: the area of the shared front room in residential buildings is greater than 6 square meters, brand elevators must have third-party testing and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than 10 square meters.
