Animating Boom Lift ( AAA quality / PBR materials )

This is a very highly detailed AAA quality ANIMATING boom lift with PBR textures.
The boom lift is realistically rigged up and animated and includes a script which allows you to easily animate the various parts of the Boom Lift
I've also included a simplified collision mesh that is rigged to the bones.
*** PLEASE NOTE : The sketchfab model's textures are a blurrier than the original textures because I downsampled them and converted them to jpg. ( making it easier to upload to sketchfab ). The original textures are each around 46 mbytes.
All textures are 4096 x 4096.
There is albedo / normal / metallic / gloss textures ( all PBR ready and configured with Unity 5 standard metallic shader ).
Various LOD levels are included and the triangle counts for each level are
LOD0 = 12,867 triangles
LOD1 = 8,173 triangles
LOD2 = 4,803 triangles
LOD3 = 983 triangles
