Procedure for Recovering LCVP
With the davit starting in the upper most position,
the brake is released and gravity brings the arms down the tracks to the lowest
position.
The boat falls on the cables are then cranked down from the arms to the level of
the LCVP by hand.
The LCVP is now secured to the boat falls.
The boat falls are provided with an automatic releasing hook. When they
are under load the hooks will not release.
The Electric motor is activated and the LCVP begins
to come up out of the water.
Once the cables are fully retracted, the arms of the davit begin to climb back
to their upper most position.
Here the LCVP is almost into its final position.
Once the LCVP is in its upper most position a safety pin is used to secure both
arms of the davit.
