Tower crane. Comes in .MB, .MA, .OBJ, and .FBX formats! .MB format is from Maya 2012, but .MA format included so that the model can be easily opened in any version of Maya. To open in an earlier version of Maya, open the .MA file in a text editing program and in the first few lines change where it says '2012' to whatever version number you have.
Textures are included in a zip file with the download.
