A crane's tiny but essential load

. Part of the fun of my current dig is watching the crane next to us building a tall apartment complex. But this afternoon I saw the crane lower its heavy chains right in the middle of the construction company's container-offices across the street. Someone filled up the two plastic bottles with cold water and the crane operator raised them. If you click on the photo you can see the bottles dangling.

  Then the brave and thirsty man climbed out of his cabin and reached out to pull the bottles in. All this about twelve stories up.
