Based on the same principle as that of a classical vise-grip, QUIRI Hydromécanique offers a innovating solution of Autolock hydraulic vise-grip with failsafe lockout allowing to lock/clamp strong forces from 5 tons up to 100 tons.
Diverless clamping
Specifically designed to operate subsea, the Autolock hydraulic vise-grip can be activated by hydraulic downline with Hot Stab connection plugged by ROV to the HPU located on board.
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].
