this is an older picture but i always like looking at it.

I bet that was fun but then again a guy could get run over if not careful.

So I'm wondering how the pump in the lower right hand corner is getting any mud to it? Great pic by the way. Why so many, yardage per hour requirement or something?

looks like the pump on the lower left corner (parked on the street) is feeding it through system.

Perhaps a little over pumped but a well thought out approach.Yes,the pumps could out do the mixers but the overall yds per hour counted.I would say a well done is deserved.

HAHAHAHA!! Thats the funnyest thing ive seen in a loooong time. How the hell???? This must the the most extreem poor ever!! Or is there any body that can do it better? Todd. I think this guy deserves a T-shirt. (at least)

Some things to think about.This pour had very specific time constraints,They city dictated time of closure on permits,mmm.When figuring yards per hour,per pump,it greatly reduces hopper area safety.By this i'm only stating less mixers to each hopper.Yes,the pumps can produce staggering production,that translates into helter skelter,more exposure to accidents.By slowing down the trucks to hopper it gives everone more time to think/react.Once one looks at the whole picture,not out of line at all.Say a steady 100 yards per hour safely vs 200 helter skelter it doesn't take long for a savy company to stand out.

You are trying to say that all this booms in the air so close together and all those trucks so tight besides each other is safer than half the amount of pumps and pumping double as fast? hmmm That can't be the reason..

If one looks real close to the picture,paying attention.All the pumps converged on the initial lifts of matt pour,as soon as they could some booms pulled back to the top out.As each pump got to where the other could overlap they pulled pumps out.

If you get the chance to participate in the planning of a matt this big,do it.It really is interesting.

It could also be something to do with even placement, etc. Some jobs have engineers that think up some very crazy specs and so on. Maybe it was easier to have even coverage and keep everything alive with no chance of cold joints, etc. There is alot of area there. In the nuclear world we have overkill on pumps all the time just to be safe. I'm talking 3 pumps on a 300 yd wall thats 23' high and 2' thick....I'm sure there was a reason behind it. Or maybe western had one hell of a salesman that got the contractor to pay for all those pumps... or I suppose it could have been a bad one that could have given them away... who knows why. Just enjoy the picture because it is a good one.

FunnyBoom 

Now that you mention it.We did a 2,000 yd matt pour in Central City for a cassino.Big contractor,got onto an aurgument with head finisher that was running the pour.He was hell bent on starting right against the wall.Well as one might image the word fluid hydraulics didn't enter his head.Yep,the mud pushed the matt (top) over almost 2'.I'm laughing as the rod busters are trying to staighten the colum steel.

I will never forget that day,stuipid as stuipid does.Thanks for reminding me.

it was a 3m thick slab that they put 10,500 m3 into in 8 hrs

how manny plant's where invalved

All I got to say is damn thats alot of mixers waiting up the street.

Can you imagine the confusion for some of those mixer drivers? I mean some of them probly didnt have a clue as to which pump to go to.

they put large numbers on poster board andstand them up behind each pump.when they load a mixer the dispatcher puts the number of the pump it is supposed to go to on the batch ticket.
