Today I went for a little walk. While I was going down the sidewalk I found a tow crane on my path. Upon further inspection I was able to see that it was set in such a way that an elevator will carry a load up to the exterior window of an apartment. Then I saw a pair of men loading a mattress and a bunch of boxes and then I realized that since mattresses are bigger than some elevators getting them inside must be a hassle. Anyway I wonder if they do the same with taller buildings. For me its the first time to see something like this (Moving stuff to a new apartment using a crane).
