Gearboxes for shredding and recycling
Our drive systems combine maximum torque, compact design, and dynamic operation—ideal for demanding recycling applications such as shredders and crushers.
The patented overload slip clutch enables stepless hydraulic adjustment during operation and reduces downtime by responding quickly to changing material. The non-rotating design minimizes mass inertia, wear, and heat input.
Highlights
- Torque up to 400,000 Nm as standard
- Hydraulic and electric drive
- Versatile gear ratios & output designs
- Complete drive systems with planetary gearbox, synchronous or torque motor, and frequency converter
- Different bearing and sealing concepts for individual requirements
