Completely random question about escalators...

[conuly]

And google is failing me. (Though I have, for the first time ever, read about spiral escalators - cool!)

Why isn't it possible (or is it possible) for escalators to be made sized to carry wheelchairs or baby carriages or suchlike?

Is possible. Just not economic; a department store or some such would require about five times as much space for an escalator that size than it would for both a conventional escalator for most people *and* an elevator for the exceptions.
