like i said it would. three quarter throttle did 90 an hour for the first to hours. then had too slow down was to quick for concreters. there would be no worrys putting 100 to 110 an hour.

forgot it went 568 cube.

glad to see everything worked out for you. great pics

that's cool. 

Do you get paid twice for two hoses?

Awesome job great pics and video. . Keep it up

Quick question how come they used the Y? thanks

how much pipe surge did you have? did the tires help out alot?

hi guys thanks for the replys yeah the job went great. yes charged extra on meter rate too use it. used the y as you can see why in vids so you can use the power off one pump and not smash everything on the slad as you can see by how there was no kick. and too look better then the other companys in the area and get paid more win win situation. at the start with all the gear on like you can see in vids the pipes moved at max two inchs. hoses nothing. yeah tyres where great. there is nothing better then going very fast with heaps off gear on and not smashing anthing on the ground. 

also have too ask where are all the critics that where giving me a hard time for going too use it even after i siad they are great too use. well come on you know who you are. is this one off them times that i should say i told you so, but i wont just. remember if you dont do it or if your country does not do it, it is not wrong. we all do it different around the world thanks.

Hey Mr. wibau, I like how you asked about the critics.  Where are they all now?  They all told you it wouldn't work, it was dangerous.  How come they don't have anything to  say now?  Just because it is something different doesn't always make it all wrong.  They have to realize that.

What is the weight of the system ?

I have used a 5"-3" reducer and a 3"Y and two 5 meter 3" endhoses...

My compliments.  I learn something everytime I log on to this site.  Out on the job I log on from my phone.

Bullfrog,

My problem with that program is that you do not turn the pump off while disconnecting hoses. I have participated in too many of those pours to ever want to do so again. If, while yanking a clamp off of the system, you get a face/eye full of concrete... it is all part of the program.

If, instead of using the "Y" they used a diversion valve, you still do not need to shut off the pump. But with the diversion valve, when you are removing system from the discharge end, the flow is out of the other side. NO ONE IS IN DANGER
and as you know by now; that is the way that I like it. Diversion method gets the same production without the potential workmans compensation claims. I will leave it up to you to decide which method to use. ;~)

I didn't know that they didn't shut the pump down when they unhooked hoses.  That IS stupid!  Now I know where you are coming from Bob.  How much down time is there to shut the machine down, and unhook clamps, maybe five minutes?  I thought you were just talking about the y-pipe.  A diversion valve would be better, if they didn't want to stop pumping.  But you still aren't losing much time to stop with the y-pipe, unhook, whatever, then start pumping again.

The logic behind the 2 discharge system is the fact that you don't turn the pump off. The ready mix company screwed up this pour because they couldn't keep up.

At the rate they are pouring, 5 mins' is 6 or so yards that you would need to make up... every time you turn it off.

Good concept + 21 st century safety awareness is a fast pour done right; with a diversion valve.

Ask Tom, I bet he has been there & knows what I am talking about.

I know what you are saying Bob, all I'm saying is, if you don't have access to a diversion valve, and all you have is the y-pipe, turn the machine off when you have to unhook clamps.  That would make the pour all the more safer.  We do it all the time pouring through system.  You don't lose that much time.  You know how precision and brasfield pour.  They unhook and rehook all the time and still pour 100+ yds an hour through system.  But I know what you are saying about using a diversion valve, it would make the pour much safer and you could still pump while breaking hoses.  But, as well you know, we don't live in a perfect world.  This pour was probably called in a couple of days prior to the pour and couldn't get a diversion valve.  Who knows?

I am sure that no thought was given to a diversion "Y"

How it was poured is how it was planned.

I am a critic of that practice and will always be,just because you got away with it once doesnt meen the next you will be so lucky,and if you want to play I told you so,go ahead I'm not like that all I can do is give my opinion,and those or like b--holes everybody's got one,I would not do it! if there is a safer way I will always error on the side of caution,if yall dont understand that,I am truly sorry,but I'd rather be safe than sorry,you can order a diversion y fairly reasonable priced ,they are alot cheaper than an insurance claim,so,Mr Wibau I am glad you did not hurt anyone that day and I hope you have a safe career but never overlook peoples advice when it comes to safety or you may be the one with egg on your face.

I am still confused why is it better with the Y? The hose before the Y will still buck the same. Wouldn't it? i am all for doing it faster and safer. we routinely pour 900-1200 yard pt decks. actually that is about %95 of what we do. i would love to hear some good points as to why the Y. you need another crew, or atleast a vibrator guy rod crew and 2 hose men.

hi guys i just want too know where yous got the idea that i would do something so stupid as one a clamp while the line is charged or pumping. the only purpose for the y was too get great speed without smashing everything on the deck. also speed due too not enough room on street for second pump. i dont know what your hoses kick like over there cause we dont have anti kick hoses over here so as you can see from vids using the y elimates the kick. if you dont understand will film 1 hose next time at same pace and see how out off control it gets. thanks

hey pudg not trying too be a smart ass so dont take this the wrong way. if concrete goes in one end and comes out two ends. the we stop too brake back then re hook up the pump again do all that too the job is finished how is that a unsafe way off doing it. thanks

It sounds like you are not as stupid as we used to be. That is a good thing. I salute you.

I  am afraid that I have 'painted you' with my own brush. Years ago we used to pour with the "Y" pipe and never turned off the pump to disconnect the hoses as we broke back. It was fast as can be, but dangerous. I foolishly ass-u-me d that you did it as well, my (major) mistake, sorry.

thanks bob glad that is all cleared up.

as bob said i assumed the same,i still think the diversion y is the way to go,just my opinion,you only have one set of eyes your pouring in 2 places at once atleast with the diversion you switch to one side or the other,it seems like you are stuck with your way and me with mine so we agree to disagree,just seems div y is safer to me but i have been wrong before,i go with what i know thats the div y,and you the same good luck

i called in on monday to have a look it went very smooth & looked great  wish i was there for the day brings back good old memories GREAT JOB BOYS

Well it looks like most of the system is between the pump and Y so it is pretty obvious that he would have to stop the pump to take any out.

Correct me if I am wrong but I thought diverter valves only let concrete through one side at a time if that is correct what would be the point of having 2 pour points in this situation? Mr. Wibau wanted less kick and 2 pour points.

Seems to me there is an added safety factor to this set up as you have a built in relief valve in the opposite hose. If one hose plugged the velocity would increase in the other but it would seem safer then a plug that stopped everything.

For my part I am going to file this setup away and pull it out if the need should arise.
