A crane made by a group of mechanics out of old crane parts and other scrap.  It can lift heavy loads because it has 28 steel cables holding it steady.  The arm can extend so it can lift objects higher and further away. Also there are a few doors allowing access to moving part so they can be maintained.

This is a space station as I'm sure you already noticed.  I wanted to do something complex and this came to mind.  I like how it turned out, but I wouldn't want to live there haha.
