How do lifts work?
Maybe the best way to illustrate, how lifts work is to take a virtual trip to surprisingly well -improved Wisegeek offices on the 65th floor of a modern office building. When you first enter the lobby, you will notice that the lift bank has grouped together. In fact, you can see one set of doors and a call button. When you press the call button, the command is sent to a computer controlling all lifts. The computer determines which of the elevators moves downwards and is closest to the ground floor.
When the selected vehicle arrives at the ground floor, the computer is commanded by an electric motor at the top of the elevator shaft to stop gradually. Once the computer feels that the elevator door and the door doors are on the same level, it commands electrically powered shoulders to insert both doors. At this point, you can enter the elevator. By pressing the numbered "65" button, you have now sent an order to the computer's computerization of all lifts. The computer knows you want to reach 65. Floors, but what inThe facts do, it is to use magnetic or optical sensors to count the number of dots on long tapes placed on the side of the elevator shaft. When the car passed enough dots, the computer orders an electric motor that turns the winch to stop.
lifts use steel cables and powerful reel to lift or lower their car. To reduce the amount of energy needed to overcome friction and gravity, lifts also use heavy steel plates as counterweights for passenger cars. This counterweight is connected to the other side of the steel cable loops and generally weighs about 40%, as well as the maximum load limit of passenger cars. When the passenger car rises, the electric motor turns the winch and the counterweight falls towards the ground. If you are standing in front of the click, you can feel the elevator tie. This breeze is caused by anti -puddles when they pass through your floor.
Once the elevator's computer senses that you have reached 65. Plora, eLectric engines open the elevator and lobby doors. If you should accidentally hesitate between the doors, mechanical and electrical sensors should prevent the door from closing. If there is no elevator car behind the door to the hall, the hall doors should not be opened. The elevators have a significant number of redundant systems and safety features, including emergency brakes, call boxes and shock absorbers. The chances of elevators that burst all their cables and drop to the ground are virtually zero.
Believe it or not, there is a reason why it sometimes takes a long time for lifts to get to your floor. The computer controlling all lifts is programmed to provide the most effective service. Elections tend to go all the way up before you start a trip down. If you press the L button on the ground floor, the elevators that rise up will most likely ignore the call completely. Only lifts pointing down will arrive in the ground floor in time, and that is only after the passengers' release toall other floors. That's why you might have to take a trip before you reach your lower destination.
Some modern lifts predict overvoltage at different times, such as shift changes or lunch breaks. Computers responsible for these elevators can send more cars to a particular floor at a certain time to handle sudden demand. The elevators can head down to the parking garage or to the company café based on the history of the elevator. Future elevators can find other ways to meet the needs of passengers without delay caused by contemporary philosophy "up or down". Call buttons can also be replaced by interactive devices that respond to voice orders or electronic badges worn by employees working on the floor specificity.
