I've seen this machine quite a few times while walking around Seoul. This one I happened to capture right outside of my apartment. It's a lifter that helps people move objects, boxes, and furniture out of their apartments via their window. I love this concept. It's so much easier than walking things down the stairs. We are probably going to move to a different apartment in March, but alas our windows don't open up accordingly and we will have to pile everything in the elevator. I'm not complaining one bit.
