Cop a Load of This

Oh dear, to be miss informed, I guess everything on social media must be true

Check out the list on the ship unloading the transformer.

They are apparently using the ships cranes rather than a ground based one. That much weight over the side will definitely "Rock the Boat"

The list is normally counteracted by adjusting ballast water in the tanks, which makes the whole unloading process a long one one, as they have to shift water not only as the load goes over the side, but again as the weight comes off the crane.

I don't think the old ships did live pumping with normal working cranes. They just put up with rock and roll as the cranes (There could be 4 or more) worked away. That super load may have had some arrangements but it does not look like it from the list. The ships are so large now that a few containers, no matter how heavy, swinging on and off make SFA difference. You occasionally see container ships rolled over at the dock when the second officer ballsed up his mathematics and stacked too much on one side during loading

Unless it is a dedicated heavy lift ship super big loads are handled by shore cranes leaving the ship sitting upright all the time. Most ships don't even have loading cranes now.

Of course at sea the Engineer pumps ballast, water tanks and fuel tanks left/right, front/back to keep the trip trimmed but not constantly.


Normal unloading list in NZ back in the day.



Ship stays level with external crane but in this case with the ship crane sharing the load it will lean as the box swings out. Both operators must be co ordinated.


Bad maths


Even worse maths



Even a ton of horse hanging out can lean a large ship.

Another pic of the transformer load

There is a utube of a ship being unloaded by a grab on the ships crane ,with the ship rolling wildly in time with the throw of the grab ,and the sand or whatever landing clear over the wharf ,about twice the normal reach of the grab.......have to be Vietnam or China or SE Asia somwhere .........there are Utubes of sand boats running with the piled sand hoppers completely submerged ,the explanation is the wet sand cant absorb any more water ,so the hoppers underwater doesnt affect the trim of the ship.

I love all those Scammells. I cannot decide which I would rather have. The Contactors hauling the transformer (I think I can see a third one pushing) would be more practical but the WW1 lowloader with the tank would be amazing to display. It would have been a problem stopping it with that load and no front brakes, probably none on the trailer either.

No worries of blowing a tyre under the weight? Love all the photos sent in by those members prepared to share, wether from
many years ago or current. Thanks to all those who contribute to the content of our site. Dave.

Believe it or not, but solid rubber tyres, especially on steam waggons, due to a combination of imposed weight and speed did blow out. The rubber internally would got hot and expand causing a bulge which would eventually blow out. Makes a bit of a mess with semi-molten rubber spewing out. I actually witnessed this happen on a Sentinel DG6 waggon back in the 1980s.
