3d crane – self build type – blend file;
This 3d model has been fully labeled and coloured, the detail level is above average, even the cab has a seat, the sections for the main tower can be built up to your own height.
You will need cycles rendering engine with CUDA core rendering enabled to get the most out of this model. The model and scene are supplied in the blend file, so that you can change the colours to taste, also render at the resolution that you may want.
This is a medium to complex model, and may take some time to render without GPU rendering enabled, you have been warned!
Of course if you have blender you can export to most file formats. :)
