TOX Powerpackage with "Safety Rod Catcher"

Function:

The safety rod catcher is held open with air pressure. Loss of air pressure will cause the unit to clamp on the cylinder rod. The energy of the drifting or falling load is used to generate the clamping force. The clamping force increases as the load increases. Internal springs force wedges to clamp the cylinder rod once the air pressure drops. The rod catcher will prevent the cylinder rod from extending unless the static holding force is surpassed. The clamping force is released by applying air pressure and retracting the load.

Closing pressure: min. 2 bar (30 psi)
Opening pressure: 4 bar (58 psi)
Max. operating pressure: 10 bar (145 psi)

Controls:

Requires a 3/2 -way valve.
For most applications, use the diagram shown below. During each cycle, the 3/2-way valve is actuated unit. In cases of air pressure loss, power failure, emergency stop, or other failure mode, the rod catcher clamps the cylinder rod and stops the load.
The clamp position can be monitored with proximity sensors.

Recommendations:

If the plant air pressure fluctuates, such as a pressure drop at the start of cycle, it is recommended to install a check valve in the air supply line to the rod catcher control valve. If shock noises or vibration occur during the release operation, a flow control valve can be installed in the air supply line to the rod catcher control valve.

Electrical Control:

Electrical controls must conform to all applicable local and national regulations for presses. Buyer is responsible for proper installation and maintenance of safety systems.
