Helix Escalator: Conceptual Escalator Using my knowledge of mechanical engineering I aimed to design an escalator that could utilize the space between floors as well as provide the same safety benefits as a normal escalator but in a more localized area. Rotating the Helix escalator’s thread core causes the steps running on the thread to move down or up. When a step comes to the top or bottom it then transitions from the thread to a runner carrying it back to the opposite end of the thread. The continuous series of steps along with the rotating motion allows the escalator to provide an endless surface for passengers to travel on. Using a threaded core allows for a smoother power transition whilst utilizing gravity and the vertical loading of passengers. To ensure that the Helix Escalator is a comfortable ride the core is rotated by a helical gearing system which can smoothly and quietly transfer large loading forces.
