Escalators and Moving Walkways, Top and Bottom, (With Short Access Covers)
Welcome to staebl.academy TGSI Design Diagram 007. I’m Dean Homicki and I’ll be your guide for this course.
Learning Overview
Let’s review one type of use with TGSIs on Moving Walkway, in this case, an Escalator, and together extract what the Australian TGSI Standard requires of the situation.
Warning TGSIs Shall be set back 300 mm with a tolerance of +/- 10 mm from the leading edge of the moving handrail to a minimum depth of 600 mm, for the full width across the Path of Travel, and in between the centre line of each Moving Handrail, and must be perpendicular to the direction of travel.
TGSIs for this application shall also conform and perform, with the applicable Slip Resistance and Luminance Contrast Requirements.
Here is a real-life situation of an Escalator showing the Bottom with Integrated Composite Warning TGSIs installed on the Access Cover.
We are going to now convert this image it into a perspective line drawing and view how TGSIs have been used in this application. Here’s the line drawing of the image.
Learning Session
How to use TGSIs in this situation?
In this example, people can approach this wide pedestrian crossing from various angles.
For the orientation of persons who are blind or vision impaired, applying this knowledge enables us to determine how to use TGSIs and conform to the Normative and Informative Guidelines of the Australian TGSI standards.
Let’s Begin.
At the Bottom of the Escalator, we have an ‘Open Area’ - that is, an area that is accessible at any angle of approach to the hazard. The hazard is the moving walkway.
This applies to the Top of the Escalator or Travelator too, an ‘Open Area’ - that is, an area that is accessible at and any angle of approach to the hazard.
Here are the moving Handrails. One on the left, and, one on the right.
So, from the start of the leading edge of the Moving Handrail we require Warning TGSIs to be set back from the face of the moving Handrail, 300 mm with a tolerance of +/- 10 mm for a minimum depth of 600 mm. This equates to 12 TGSI nodes at 50 mm spacings. And, for the full width across the Path of Travel. And, must be perpendicular to the direction of travel.
As the Escalator has moving handrails on each side of the moving walkway, the TGSIs shall be installed in between the centre line of the Moving Handrails in this instance as this is the accessible path of travel. Warning TGSIs would also need to be installed at the Top of Escalator in the same manner.
TGSIs for this application shall also conform and perform, with the applicable Slip Resistance and Luminance Contrast Requirements.
And here is a real-life TGSI application once again.
