why a ground survey for a heavy lift crane is expensive:

Because when you get it wrong, its going to hurt!

It would be rated to lift 825 tonnes i very much doubt it actually weighs in @ 825 tonnes. It was written by a jurno

Can someone tell me why they always lift sideways. I'm not am expert crane driver, but surely extending the jib over the cab would be more stable? It can't be to do with reach as they all were way out from the chassis anyway.

 

[rhumlady]

As far as I know once the stabilisers are out all the wheels are off the ground and the vehicle becomes a platform the crane can rotate on. Ballast at the opposite end to the jib supplies the counterweight. I saw a large crane a few years age that was accompanied by a fleet of artics, two of which carried the counterweights.

The largest i ever had on site was a 300t crane that came on 3 lorries

I regularly design temporary foundations for cranes. Interestingly that one seems to have fallen over backwards under the influence of the counterweight. Lots of people struggle to grasp the fact that a crane which is not lifting is often on the point of falling over backwards.

I went to see Ainscough's 1000t beast when it did a lift in Edinburgh a few years back. Quite a sight.

That must have been one sexed up frustrated big avian!

I did a shoot one New Year's Eve in Hull. It was through the night. They were cutting up a and removing a deck in the Princes Quay multi-story car park which had been mixed wrong and the concrete never went off. That was a 500ton crane. It was jammed in so tight in the street (Waterhouse Lane, if you know Hull you'll see how that may have damaged business) that as the crane swung it bent a lampost.

I did wonder how the driver got out but read that the crane was not in operation at the time. Which leads to wondering how, if it was not in operation, it came to fall over.

The operator would not have been in the vehicle driving cab even if it had been in operation.

Guess the carne operating cab is the bit just above ground level

I couldn't make the original link work. I presume its this incident:

http://www.dailymail.co.uk/news/art...e-Giant-vehicle-topples-Scottish-harbour.html

It will be an interesting drains up on what went wrong. Was there a survey? Was it carried out properly Was the driver/operator given proper instructions? Did he follow them?

Of course those who think "elf'n'safey" is pointless won't be interested in those questions.
