Moving in South Korea

We woke up this morning to some really loud noise and decided to find out what was playing the alarm clock today. We were shocked to see that someone was moving. It wasn't the fact that they were moving that shocked us but how they were doing it was completely out of the ordinary for us.

They have 2 trucks, 1 is to load their stuff in and the other truck clamps into the ground like backhoe doing some heavy lifting and raises a ramp to the required floor. A shelf moves up and down the ramp as required effectively bringing their things down from the 14th floor to the ground. I'm thinking they bring down the furniture through the elevator though as we saw a big pile of furniture near the security guards hut yesterday and people were tearing through the pile looking for gold, and that's were we found our new mirror.
