New Cranes On board

[craig1912]

Ship has arrived from China with new cranes for Southampton - looks a bit top heavy!

That's remarkable. I would have assumed they would arrive as a kit to be assembled in place.

Seen a video of this sort of thing before, loading and unloading is entertaining.

Similarly with other chunky cargo like trains that comes on and off in one big lump.

With the cranes chained (welded, even?) down, wouldn’t the ship (and its engines, machinery etc) still give the overall package a lower-than-it-appears CoG, much like a double decker bus?

How do they get them off the boat, an even bigger crane, or do the roll them off with a big heavy duty gangplank?

More or less this; they ballast the ship so the deck is more or less level with the quayside or wait for the right tidal state and then carefully roll them off. They usually use heavy-lift wheeled platforms as used for moving ships around in shipyards etc. although there are other methods. A pair of new cranes were installed at Greenock container terminal last year and they arrived in the same way.

Yes this, ship is ballasted to effectively roll them off. I ll try and get more picture on Tuesday but they are welded to the deck.
They also needed a new power supply all through the docks but they give extra reach to cover the biggest ships and can handle two containers at a time.
Set off from China at the beginning of April.

The sad thing is that we can't make our own cranes.

You'll need a crane for that. Oh hang on...
