Technical highlights

In addition to the robust, universal cutting unit, indestructible body and reliable, completely maintenance-free pusher technology, the technical highlights of this product also include a resilient drive system that comes with a safety coupling. In contrast to standard
plastic recycling machines, the QR class does not require a shaft stub, as the gears are integrated in the rotor. This results in a significant
reduction of repair efforts. Yet another outstanding technological feature is the hydraulic service flap that allows quick and
easy access to the cutting chamber for removal of foreign objects.

The simple operation is based on a high-resolution touch-screen display, intelligent pusher controls, long maintenance intervals and the quick and safe access to all machine components. All these factors combined make the operation and maintenance of these small plastic shredders as easy as never before!
