What It Is
The anti-shock clutch system acts as a mechanical fuse — a friction-slip torque limiter that caps the torque transmitted to the shredder shafts. When an extreme overload occurs (heavy contaminant, jamming), the clutch allows controlled slippage, dissipating the excess torque and protecting the motor, gearbox, shafts, and bearings. Unlike conventional high-speed shredders that rely solely on electronic protection, this purely mechanical system provides instantaneous, fail-safe response.
How It Works
Calibrated for maximum torque via pre-tensioned springs. During normal operation, the clutch transmits full torque through friction discs. When torque exceeds the set limit, the clutch slips, absorbing the peak load. Once the overload clears, it returns to full torque transmission automatically — no manual reset required.
Key Benefits
- Direct mechanical response — independent of electrical sensors. Continuous protection with no reset required.
- Prevents damage to high-value components (motor, gearbox, shafts, bearings), significantly extending drivetrain service life.
- After the overload clears, the system returns to full operation automatically.
- Simple maintenance: 10 minutes per week for spring verification and retorque with a torque wrench.
- Engineered for materials with heavy contaminants: C&D waste, metals, WEEE, industrial waste.
Equipped Models
- Pre-Shredders (PR Series): PR4000, PR5000
- Dual-Shaft Shredders (D Line): D290, D365, D460, D535, D610, D690

Two-Level Protection
Level 1 — Smart Automatic Reversal (PLC): for light to moderate overloads, the PLC triggers automatic shaft reversal.
Level 2 — Anti-Shock Clutch (Mechanical Fuse): for extreme overloads, the torque limiter slips to protect all drivetrain components.
The anti-shock clutch system is standard equipment on the PR4000, PR5000, and most D and Q line models.
