Soloing escalator

This is a recording of an escalator at the main bus station in Helsinki, Finland. I heard it making this sound one day. It was quite loud in the space and I heard if from far away. It sounded like a street performer playing an odd instrument. I imagined that a drummer would have had fun jamming along with this.

I missed the opportunity to record it that week, but luckily the thing wasn't fixed the next week when I was again at the same place.

This was recorded with iPhone Xr, so it's not super quality (I actually took a video really close to the escalator, hoping the video recording gives the best sound), but maybe somebody finds some use for this (the sound can likely be well isolated). This is as unprocessed as it can be, straight from the original video.
