Anti-Slide Devices

Perhaps this is common knowledge, but I just learned that those raised knobs between escalators really are there for the sole purpose of discouraging people from sliding down the ramp. I had always assumed they had some kind of structural function.


Anti-slide devices are used on high-deck escalators (as in Figure 11.4.2) to stop packages or persons from using it as a slide.

I always thought they were for kids to grab, to see if they can stop the escalator.

You can still slide down, but unless you're a slalom expert, it's going to be painful.

I did it all the time in the early 70's. Not as hard as you think, the little rubber hand rails keep you sliding down the center. You had to be quick on your feet to stick the landing.

Yeah, I've known about these for awhile, mainly because of the MBTA station at Porter Square, which has these great glove sculptures along the escalator, which also function as anti-slide devices.

Some people share too much when they are drunk. One guy admitted, while I was playing Oscar Brand's " My Name It Is Sam Hall", that he had slid down a banister backwards when he was a kid. Yeah, he hit the newel post and now has one!
