Nice one sir

[@linh3081]

Can you explain why the valve is closed or opened in each mode. I dont understand the working principle.

[@kymsantisteban2909]

How many seconds is the regulation on how long it takes for the davit to swing.?

[@marineengineerworks]

not more than 1 minutes sir

[@salahuddinlablu3273]

Sir please make a video on basis of davit lifeboat Motor wiring diagram

[@marineengineerworks]

Next time when im onboard sir.. im in vacation rigth now sir

[@linh3081]

please make video about working principle of davit crane rescueboat, why close and open the valve outside.

[@marineengineerworks]

what valve do you mean sir.. electric. accumulator or manual

[@linh3081]

I mean when use accumolator we close one valve and open one vavle. When use handpump we open one valve and close one valve. Is that right? Why we have to do that? Can you explain working principle.

[@racheddjafri3154]

Does the accumulator required electricity power?

[@marineengineerworks]

no.. no power.. its only hydrualic power inside na accumulator

[@racheddjafri3154]

@@marineengineerworks thank you

[@allenjoycepepino5714]

how about if the accumulator is not working? or not charging?

[@marineengineerworks]

you can use manually by pumping the hydrualic.. ☺️

[@salahuddinlablu3273]

Sir can you provide me wiring diagram.

[@chifranzvlog7139]

Ano2x po ung 3 steps for lunching

[@marineengineerworks]

first electri.. second accumulator. 3rd manual hand pump

[@linh3081]

​@@marineengineerworks The first mode using electricity is we can slewing out or hoisting by electric motor. The second and the third mode only can slewing with valve, if want to hoist can only use the stick manually. Is this right??
