SAFETY FIT®: Hydraulic Overload Protection – Safeguarding Drive Systems

1. Overview of SAFETY FIT®

SAFETY FIT® is the ultimate safety solution for industrial power transmission. Functioning as a “mechanical fuse,” it is designed to prevent the transmission of excessive torque. When the actual load torque exceeds the pre-set value, SAFETY FIT® instantaneously releases internal hydraulic pressure and switches to a free-running state. This disconnects the drive, protecting the entire machinery system from catastrophic failure.

2. Superior Technical Specifications

The product is engineered to accommodate systems of all scales, from compact machinery to ultra-heavy industrial equipment:

• Extensive Shaft Diameter Support: Compatible with shaft diameters ranging from 30 mm to 720 mm.

• Massive Torque Protection Range: Capable of controlling and transmitting torque from as low as 0.3 kN·m up to a maximum of 7,180 kN·m.

• Instantaneous Response Mechanism: Utilizing hydraulic principles, the device responds rapidly and accurately to load fluctuations, providing significantly higher reliability than traditional shear pins.

3. Benefits of Using SAFETY FIT®

• Comprehensive Protection: Prevents shaft fractures, gearbox failures, or motor burnouts when the system suffers a sudden jam.

• Minimized Downtime: Once the overload issue is resolved, the device can be reset quickly, allowing the production line to resume operation promptly.

• High Precision: The protective torque value can be precisely set via hydraulic pressure, eliminating the inaccuracies caused by material fatigue common in standard mechanical devices.

• Cost Efficiency: Reduces the risk of replacing expensive drive components and avoids the high costs of unplanned production shutdowns.

4. Typical Applications

SAFETY FIT® is an essential protective component in heavy industries:

• Steel & Metal Rolling Mills: Protecting rolling shafts during workpiece jams.

• Mining Conveyor Systems: Preventing chain breakage or motor damage during sudden load spikes.

• Crushers & Mixers: Safeguarding the drive train when encountering hard foreign objects.

• Marine & Energy Equipment: Stabilizing drive systems in marine vessels and large-scale turbines.
