Bloody hell! Was the pool full of water or something!?

With a lever that long is almost good enough to undo the I5 crank bolt

Seriously, I thought there was some warning or gauge that tells the driver he is too extended... guess not from all the youtube crane incidents .

Yeah, uh... that's not meant to happen, is it?

I think they have a chart of weight / extension / angle. Maybe newer cranes can tell automatically - obviously not this one.

You could see it coming all the way!!! I love the guys reaction..."what are we doing here?" I bet the crane driver needed to change his underwear! Brilliant clip.

Yeah they are supposed to have a tweeter that bleeps when its near the load limit, based on load cells. Obviously yank cranes don't have to have this
Also the counterweights should extend to balance the mast as it extends.

hope he's got insurance

It's very simple when you plan a lift with a mobile or tower crane. There are limits dependant on weight of object and jib length. They did everything wrong. One thing you definitely don't do is extend the jib length during a lift. This is a pre determined point dependant on the limits of the crane and the weight being lifted and in this instance they obviously exceeded the cranes limits. You can jib up and down slightly (to hit your pre determined target lay down point) but not 'in and out'. Surprised it went over though, that pool must have been bloody heavy!
