This 2006 portable Shred Tech shredder is hydraulically powered, and has a Cat C15 diesel engine.  The Cat C15 has the power to get through both car and semi truck tires, at about 4 ton per hour. This shredder produces a 6-12 inch primary shred, and a 6 inch chip with the material being run through again.  It is grapple loaded, and has an Action Vibratory Conveyor that could be used as a screen, but is currently not set up for sizing material.  The trailer is a triple axle, and it has just been inspected so it’s ready to go to work.  In addition, the knives are hard faced, and the shredder comes with a spare set that are ready for rebuilding.
