This sound was created artificially. In general, it consists of four main layers. 1. The sound of noise overboard (created from white noise). 2. The sound of clanking of the inner skin synchronously with the sound of wheels (created from white noise). 3. Metallic noise. Created from the sound of bolts shaken in a metal can. 4. Actually the sound of wheels (created from ten sounds of various metal and percussion). A rather complicated equalization was applied, and filtering in several stages. Also, the sum of the sounds is processed by the convolutional reverb.
