How do you operate a Safety Chuck?
1. To load the Safety Chucks for take up or pay off operations, rotate the round locking collar or handwheel to zero degrees. Tilt back the handwheel exposing the square pocket. Lower the shaft square journal into the square pocket of the Safety Chuck.
2. When the shaft is seated in the Safety Chuck the handwheels are closed by hand prior to start up. If the roll should rotate before the handwheels are closed, the handwheels will automatically start to close at 5 degrees either side of the zero. They will be closed at 15 degrees either side of the zero. This is the safety feature of the Safety Chuck.
3. Start the operation. Torque is transmitted through the Safety Chuck to the shaft. The speed of the take up and, the amount of tension required can be controlled with the inclusion of a compatible Boschert Brake.
4. At the end of the operation rotate the handwheels to zero degrees, tilt the handwheels back and remove the Air Shaft
