ONBOARD ENGINE ROOM CRANE TROUBLESHOOTING

We have a 12.5 tons of lifting capacity for our engine room crane. We will be lifting up 9 tons of cylinder liner in Korea but we are having trouble with our high speed up operation.
How to trace this kind of trouble?
Come and join me in this new video.

I've been a crane tech for 15 years, you're very good at troubleshooting.

[@k22bngpny]

The Crane is one of the most difficult machinery on board to troubleshoot not to mention the heights and cramped spaces,along with the mooring/anchor winches. I’m glad you covered this on you videos. Thanks Leckyjake!

[@zilwegewd]

I admire your mechanical skill, and electrical knowledge.

[@leckyjake]

Thank you very much and Have a good day

[@warrenstaben6166]

I am so glad that I stumbled on to this channel!

[@leckyjake]

Thank you very much for watching

[@MajidKhan-ds7bs]

Your videos are very good for knowledge .

[@Mark_The_Mayven]

Good troubleshooting..Divide and conquer 👍🏼

[@geraldlawrencecortez1103]

I'm very thankful leck that you are sharing this kind of video to us. Godbless always and more blessings to you and your family. :)

[@SLYTECHAfrica]

Thank you so much you are my mentor in this field

[@SLYTECHAfrica]

But I have questions the electromagnetic coil in charge of the breaking system I would have love you explain it in detail sir

[@ilopez7372]

Great video !

[@KarabaileckyTv]

great video.👍👍

[@wilberthlawas5888]

I'm always following your vlog & I've learned a lot. Tnx sir jake

[@eedgaming689]

This is so interesting

[@willrobbinson1]

interesting job VERY wide rang of gear to look after , wish u all the best ps love the detailed vids

[@leckyjake]

Thank you very much for this wonderful comment

[@mlenstra]

Great video again, keep up the good work! What generally causes such a low resistance in the magnetic brake coil, do a bunch of windings just get shorted together? If the resistance is 1/10th of normal value, the current would be 10x the normal value, wouldn’t you expect that to blow a fuse as well?

[@Marineelectricalknowledge]

Waiting for next video

[@leckyjake]

Waiting for the spare

[@johncantrell614]

We have a bunch of those at the shipyard that I work at, and they can be some of the most finicky things to work on, especially the older units.

[@leckyjake]

And it is difficult to access from the height

[@johncantrell614]

@@leckyjake yes sir! 🙂

[@andyboydyurong4360]

Wow!! laking tulong Po Ang video n Ito...Gbu

[@robertopunzalan8734]

Good analysis po sya pero di nya napakita ang mga limit switch na syang mag ti trigger sa mga
Contactor ng
High speed up and down

[@leckyjake]

Hi Roberto, going back sa video, yung contactors are both activating without the motor connections kaya ibig sabihin the circuit is healthy. It is a troubleshooting video kaya need to move to the next step of fault finding.

[@taufiksheikh89]

Congratulations on 17nk subscribers sir❤️

[@acel5378]

I hope idol some day I have a job in on board.im electrician in the Philippines.

[@prasadp768]

Very interesting vdio👍🏻

[@leckyjake]

👍👍👍

[@mithileshramteke3882]

Thank you

[@АлександрБерезовский-у5м]

Thank you for interest video!!!.

[@romanvladynov6355]

Dear Jacky could you please advice, what was measuring instrument green color did u shou us?
One more thing, can you create good practice video about scrubbers, because there's nothing information in UA-cam.
Great work!!!!!

[@cesarsanchez3067]

You the man .

[@MaxKharevsky]

So you press the button to check voltage on the output of rectifier and also voltage on the output of contactor, right?

[@christianGermany995]

Idol Lecky Jake, aspiring Electro Technical Officer po ako. ask ko po if ano po ang mga requirements/trainings para makasampa sa barko. if okay sir gawa kana rin sir ng vlog step by step process. salamat idol! keep safe. Go EE youth!

[@MaxKharevsky]

So input voltage on rectifier is 220 and output voltage is 110 dc current, right?

[@GeeWillikersMan]

Out of curiosity, what would you expect the brake winding resistance to be?

[@leckyjake]

Around 350 ohms

[@scottbustos819]

I've learned to always verify what the resistance should be and not assume.

[@entertainmentguy4509]

will you make a video of replacing that magnetic coil?

[@MaxKharevsky]

How you know, that 23 Om is low resistance for this coil, where possible to find 🤔?

[@rockyclassic]

RIP bro😢

[@WillmannElectrical]

Are ring-lugs standard for marine electrical panels? I do commercial/industrial you seem to have way more. Great faultfinding video mate - ill be recommending to my all my apprentices

[@leckyjake]

Thank you very much. Yes, lugs are common standard in marine electrical. This kind of comment is what keeps me going.

[@gijoecam]

So if the brake is failing to release despite the applied voltage, why does the low speed work?

[@leckyjake]

Because there is a separate motot for the low speed

[@joevisdiplomaticmoves6306]

Thanks for the reply,I got you

[@joevisdiplomaticmoves6306]

High up high low,uses dual speed motors right

[@leckyjake]

In this particular crane they have separate motor.

[@charlesvanlaganson5281]

Sir can you send the link for part 2?

[@japhetjalandoni2751]

Hi sir pwdi b e Megger test Nalang Ang magnetic brake coil para Malaman kung defective ma eto salamat

[@vigneshkrvd]

Thank u very much sir 🙏

[@leckyjake]

👍👍👍👍

[@artemgulko2705]

How much might be resistance of the good magnetic breaker ? Around 0.1-0.5 ohm ?

[@leckyjake]

Around 350-450 ohms

[@emadsiddig6631]

Hi dear

[@wilberthlawas5888]

Sir Jake how much the exact resistance?

[@pudaytv436]

Wartsila b yan dre?

[@leckyjake]

MAN B&W

[@MaxKharevsky]

You didn't show how you check equal voltage going from contactor to motor 😢

[@ushansandeepa748]

Video 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

[@edgarlagumbay1266]

Sir pede pahingi diagram nyan ng two speed motor ,three phase ,thanks

[@unelectedleader6494]

Everything testing out ok. They’re just lying to you man. Pretending stuff is broken
