The technology developed by these industries and the introduction of steel beam structure jointly provide the use for today's spring freight elevator.
From the coal mine to the middle of19th century, elevators were driven by steam and used to transport bulk goods in mines and factories.
These steam-driven devices were soon used for various purposes.

Extended data:
Safe use of elevators:
1, in case of fire or earthquake, it is forbidden to take the elevator;
2. When taking the elevator, please don't play or jump in the car, because there are many safety protection switches in the elevator. When someone jumps into the elevator and causes the elevator to tilt, it is likely to trigger these switches and cause the elevator to enter a protective state. At this time, the elevator will stop quickly, causing people to be trapped;
3. No smoking in the car, keep the elevator car clean and ensure the service life of the elevator;
4, when using the elevator to transport goods, it is forbidden to use sticks and other items inserted into the elevator door to wait, so as not to affect the elevator structure and cause danger;
When the elevator breaks down and is locked in the car, you should press the "emergency call button" and wait for the professionals to handle it. Don't pry open the elevator door to escape, so as not to fall;
6. When taking the elevator, be careful not to let the child's hands touch the door panel to avoid being caught when the elevator is closed;
