Construction Drawing:This means that for a given floor to floor rise, the work point (WP) ? the point at which the 30 degree incline intersects with the floor level ? to work point (WP) dimension is always the same, regardless of the manufacturer (floor to floor rise x 1.73205.) Since manufacturers configure escalator components differently, the distance between the floor level WP and the point at which the escalator intersects with the building structure ? known as the Face of Support (FOS) ? varies. As a result, all manufacturers' space requirements between the WP and FOS have different dimensions.As shown in figIn our Project we are using DC motor for roller and robotic belt for slider.
