V- Concept Design

1. Staircase

   Since this project is associated with escalator. As a group we have visited SCITECH. And we have seen how the regular escalator moves to link it with our project. And we have also counted the challenges that’s might faces us during the semester.
   A typical escalator in the Saudi Arabia is made of a stainless steel step and moving walk available in horizontal as well as inclined types with cleats made of die cast aluminum and is used for moving people. And also we are trying to follow the standards that are available in our library and online recourses.
   When we selected the materials for our project, us engineers are looking for metals and materials that are: - strong, light weight, easy to fabricate, low maintenance and that’s why we have selected the stainless steel and die-cast aluminum.
   For example stainless steel is can be used in many applications like tankers, rail transportation.
   
   

   Advantages of spiral escalators

   The advantages s of escalators are many. They have the capacity to move large numbers of people, less space, low energy and less cost. This design especially with the inner and outer tube is design to be flexibility offered by the casting process this flexibility enables the designer r to match the design of the staircase component to its function.
