Why don’t they rig some heavy cables to the top before pressing the button ‘just in case’? At least they could give it some winch-action if needs be. (I suppose it would show a complete lack of faith in the method statement, probably scare the customers off!).

I just did a quick calculation on this. Using estimated weight and size etc.

I came up with a figure of 56 tonnes of pull would be required to overturn that chimney.
Would need to be a pretty big rope to have that sort of safe working capacity.

Just getting that kind of weight up the chimney would be some job.

The old military fodens have a 25t single line pull winch I think some of the tank recovery units have 4 so wouldn't be unfeasible to do it
But will be interesting to see how they tackle it
It's happened before so someone must know what to do

fxck all to do with me before anyone asks,all they need to do is chuck a fag in one of them tanks near it would soon come down

Just needs a technical “nudge” at the top with a helicopter

You'd think if there was space to fell it like a tree they might have done it that way. Maybe there isn't and it'll be interesting to see what they're gonna do.

That is nearly as impressive as the explosive demolition contractor in Staffordshire who managed to flip a silica sand storage tank neatly up side down ...... without substantially reducing the height.

I hope they manage to find a away to get it down before any high wind occurs.

couple of well aimed Milans @Rob65 ?

Even though it is apparently sheared off, and you would be pulling from the top? That sounds a lot of pull (though I’m not pretending to know an alternative figure!).

Not a huge amount needed then. 30T winch reeved with a pulley would have it over.

think @Rob65 's calc would be a worst case figure ..... it could just be stood there teetering in need of a gentle assist.??
it's a truly nightmare scenario for the contractor and could go absolutely any where .... consequential damages could horrendous

I think somebody should’ve watched a bit more Fred Dibnah.

Thought that...would love to have heard Fred's response to watching that job...

Yes, my calc was basses on the chimney standing ‘plumb’. If it’s leaning in the direction of fall it would take less pulling force.

A couple of 50 tonne machines would be easy enough to get to site for the pulling. Getting a strong enough rope to the top of the chimney - that’s the problem.

If you can only get the rope half way up it doubles the required pulling force to over 100 tonnes and that means an even bigger and heavier rope.

Still need enough clear space in one direction to fell it into though and that might be the problem.

 

[Rob65]

I think felling the chimney in a particular direction will have been the plan that went wrong.

I know the video shows it dropping vertically but that will not have been the plan.

This video is of the chimneys on the site next door that were demolished last year. My guess is that this is what they were looking to achieve with this one.

Discovery4 Removeable hitch dropped off? Brake away cable looped round hitch so not activated?

I don’t know how old the video is, but I thought this was so well known now that they had all been replaced now! That could have been rather fatal.
When I got my RRS I checked it had the bolt and brace tow bat rather than the twist and fall version.
