Gearboxes for shredding and recycling
Our drive systems combine maximum torque, compact design, and dynamic operation—ideal for challenging recycling applications such as shredders and crushers. The patented overload slipping clutch enables stepless hydraulic adjustment during operation and reduces downtime by fast reaction to changing material. The non-rotating design minimizes mass of inertia, wear and heat impact.
