Tower crane 3D model (free CAD download file)

designed in Siemens NX6

This is unfinished 3D model of Tower Crane, I designed as much as I could just by looking at images of tower cranes on internet. I over dimensioned most of model, as at first i had idea to try to make it in plastic. Most of cable work is unfinished as I do not have enough info about cable system. If anyone have informations I need to finish this design, please contact me.
