Construction
Davit's rotation is brought about by a mechanism fixed to the foundation in parallel to
ship's side. The mechanism does not change it's position, is fluid driven and in case
of emergency - driven by a hand pump. The winch mounted on the davit serves the boat
and raft, and it's brake allows to control from the deck, the boat or from the raft
"let's go". A high - speed hand gear is assigned for hoisting of an empty hook.
The davit is fitted with a complete hydraulic - electrical system. Hydraulic accumulator
ensures 90o rotation of davit together with rescue boat in case of current
decay on the ship. Rotary davit meets requirements of SOLAS 74/83/86/92, DNV, NMD, GL, SBG, PRS, MRS, DOT, LRS.
