The fun elevator installation consists of a machine room which is usually located on top of the fun elevator shaft and thus on top of the roof of a building. Herein, the fun elevator machine is placed and the switch box that controls the operation of the fun elevator. Sometimes the engine room is next to the shaft. This can be both above and at the bottom of the shaft. In hydraulic lifts does not matter where the machine room is located. An invention of the last few years is the machine room-less fun elevator. Another important part of the fun elevator is the fun elevator shaft. This is the space in which the car and the leaders themselves. Passengers get through shaft doors to the fun elevator car. In 1795 it was the inventor Ivan Kulibin who designed the first fun elevator for the winter palace of St Petersburg. In 1823 London also received his rising room. In 1852 built Elisha Otis the first fun elevator with a safety device that prevented the cage came crashing down on a cable. At a demonstration during the World Exhibition in the Crystal Palace in New York in 1853 Otis sat himself in the fun elevator. When it was almost over, an employee cut the fun elevator cable. Because of the safety fun elevator dropped a few inches down, thus proving that the fun elevator was safe. The safety system uses Otis notched rails in the fun elevator shaft. At the moment the pressure of the lift cable drops to a cable break, the claws of the cage in the rail and hold the fall of the cage against. Shortly after this demonstration Otis received his first orders. After his death in 1861, took his sons, Charles and Norton, the father of their established fun elevator company Otis Elevator Company on. In 1873 they had already placed 2000 fun elevators in office buildings, department stores and hotels. Fifteen years later they introduced the first direct-drive electric fun elevator. Older fun elevators are a liftboy operated. This is often a boy in the teen age. He stands in the fun elevator and pushes a lever up or down. He must ensure that the lift stops at exactly the right height. The Elevator opens and further close the doors. Such an fun elevator could be found in department stores, hotels and now even in subway stations. Nowadays almost every fun elevator user controlled by pushbuttons. It only makes sense then to press a button when the fun elevator is not busy with another task. All modern fun elevators are programmed to operate on multiple levels as efficiently as possible. There is one on each floor button to call the fun elevator. Often, particularly in office buildings, there are two push buttons (fully collecting), one for up and one for down (on the top and bottom floor of a single button, of course, is sufficient). By pressing the up button, the fun elevator will not stop when he passes by on the way down. Often there are several lifts next to each other and there is one on each floor pair of buttons for the entire installation. In condominiums are found usually only buttons to call an fun elevator that goes down (except on the ground floor). It is assumed that there is little traffic between floors. In the fun elevator car is a panel with push buttons, one button for each floor. Is pressed a button, the fun elevator goes to the requested floor. In very high buildings can be found in the lift sometimes be a numeric keyboard, so with ten digits, in which the destination floor can be keyed in. An illuminated panel in the cage indicates the floor on which one resides. Such a panel is often also find on the outside, on each floor. In modern systems also nowadays systems where one when calling the fun elevator instead of "up" or "down" to the level where they wish to enter to go. Below shows the lift installation in which then needs to be taken. In the fun elevator itself can then no longer choose floor. This is partly introduced in order to reduce the wrong choice.
