Doppstadt Inventhor Type 9 SA

Trailer-mounted high-speed shredder with Vario Direct Drive

The Doppstadt Inventhor Type 9 SA is a high-speed shredder built for operators who move between sites. The 3-axle trailer chassis lets you hitch up and go, while the hydraulic self-drive moves the machine around the yard once it arrives.

What sets this generation apart is the drivetrain. Vario Direct Drive transfers power steplessly according to demand, and the Load Sensing system adapts the feed to the material, so throughput stays even instead of surging and stalling. Shaft speed is adjustable from -5 to 32 rpm, which means one machine covers everything from coarse pre-shredding to a fine, uniform fraction.

Day-to-day operation is built around not stopping: automatic reverse clears blockages without shutting down, the shredding chamber opens hydraulically for access, and the machine can be started under full load.

Why choose this machine?

The Inventhor Type 9 is Doppstadt's answer to the biggest weakness of high-speed shredding — power loss and downtime when material changes. Vario Direct Drive and Load Sensing keep output steady, automatic reverse handles blockages without stopping, and adjustable shaft speed means a single machine serves several output grades. On a trailer chassis it suits contractors who work at the customer's site rather than at a fixed installation.
