QUIRI - Example of 60T Autolock hydraulic vise grips

The Autolock [1] is a positive hydraulic locking device.
The piston is locked into the sleeve (like a press fit joint); and unlocked by putting pressure in the unlock port [2] to allow the piston-rod movement.
- Vise-grip opening by putting pressure in the pulling chamber [3],
- Clamping force done by putting pressure in the pushing chamber[4] and clamping locked by releasing pressure by the unlock port [2].
