D-NP - davit of normal pivot driven by gravity.
The system is suitable for lowering a boat, including the full complement of persons, due to gravity from the stowed position to the sea level. This procedure can be controlled from either the winch position or from the boat.
In order to allow a launching and recovery procedure as appropriate, the system is equipped with an electric winch. Hoisting of the fully equipped boat, including the 3-men crew, can be realised by means of the incorporated electric motor.
In case of power failure or malfunctioning of the electric system, hoisting can also be realised manually. For this purpose the winch has been equipped with a crank handle square shaft. Upon placing of the hand crank the motor drive is automatically blocked.
