Diagrams For Escalators
Diagrams for escalators are not for the faint of heart, particularly if the intent is to build one as an amateur. Most people prefer to leave this left to the professional, although building it can be rewarding if you find the right blueprints. In fact, even the professionals cannot start without the right design. if you don't feel up to the task, another option is always to shop for a used escalator or a used chair lift, if your primary requirement is mobility around the house.
The first patent for an escalator model was designed by Nathan Ames in 1859, however, the first working escalator was introduced at Coney Island in New York in 1896. Although it has been over 100 years since the first working escalator appeared, the idea of the escalator has basically remained the same: a moving stairway. The first escalator was built by Jesse W. Reno who graduated from Lehigh University in Pennsylvania. The concept of an escalator is a simple thing, whereas the design itself is more complicated. There are three different design types for escalators: parallel escalator, crisscross, and multiple parallel.
The first type of escalator, the parallel design, is basically two escalators directly beside each other or separated by a small distance, with one moving upward and one moving downward. This design is named parallel escalator because the upward and downward escalators lay parallel to one another. The second type of escalator is the crisscross design. This type of design is usually see in department stores and stacks escalators on top of each other based on the direction that they are going in, upward or downward. This type of escalator design is used to minimize the space taken up by having multiple escalators. The final design type is the multiple parallel escalator design. This design type is just like the normal parallel design with the only exception being that there are multiple escalators that go upward as well as downward. This type of escalator is seen in many public transportation stations where there is a large amount of people using the escalators.
FYI, the honors for world's longest escalator, both on the outside and inside, go to Hong Kong. The longest outdoors escalator, at 2,600 feet, is the Central-Mid Levels Escalator, which takes thousands of commuters between the central business district and a residentialdistrict known as the Mid-levels. Meanwhile, in Ocean Park is the longest indoor one, one which connects two parts of the park through its 730 feet of steps. Makes one wonder about the size of freight elevators these guys will build!
Although escalators are usually one way, they can be designed to change directions. This can be very helpful when the multiple parallel design is used in transportation stations. One way that this can be useful is because there are certain places that have more people moving in one direction than the other. If there are many more people that need to go downward instead of upward, and there are four escalators, then three of the four escalators can be set to go downward whereas only one will be going upward. By having more escalators going downward, the traffic of people can be less congested by allowing more downward directed escalator to handle the influx of people. These machines are often used in conjunction with commercial elevators, which are just a more robust brother of the residential elevator.
One of the design factors to consider when building an escalator is the maximum angle that it can be elevated at. The maximum angle that an escalator can incline is 30 degrees horizontal to the floor level. No matter how many designs for escalators you examine, this fact will not change. The rise of an escalator is up to approximately 60 feet. Most modern day escalators are made with steps that are constructed of aluminum or steel steps. These steps move in a continuous loop where once the step reaches the top of the escalator they move back downward on the backside of the incline until they reach the bottom and the proceed upward again.
So if you're up to the challenge of designing an escalator for a business, shopping area, a home, or even for a park as big as Ocean Park, the journey always begins with having the right diagrams for escalators.
