Welcome to Norway!

wow, thanks for the picture.

damn this is going into my just for laughs safety book :)

personally,I can think of several bad outcomes.But then again who am I?

are you getting paid by the hour or the square foot?

Just don't post any pics of you pumping concrete through that thing on the end.  Using it as a seat is all its good for.

Just use a 3.5" hose and you'll be fine.
Tell the customer nicely first you do it this way, if not tell him it's your way or the highway, best to wait after the mud has arrived. :P
Seriously, customers here need to be educated on how to pump safely, with all the HES BS nowadays it's wrong to have the customer to tell YOU to break the law because he needs a handle to support his lazy ass on.
Once they realize it's easier to move around a thin hose than a big, stiff 5" with 20 kg of metal on the end it gets easier.
Try 2.5-3" on the cheap block things people like so much to build their houses from here and a good customer will be impressed with how much cleaner it is to use appropiate equipment for the job.
Raymond and Vidar are good guys so I guess they'll be reasonable with your judgement on how to do the job your way.

Funny. Nice job!

I mean hanging it up. Straight from the boom. No need to have that fat 5" hose, you'll never need it with the nice mud here.
With safety wire/chains there is not much that can go wrong with the reducers.
And 3.5" is about as big as you can go with the high slump mud around here, 4 inch is for volume, 8+ on my Putz.

whats the point! 5 to 4 then s tube, why not 4 or 3.5 and be done. that would take ur head off if it let loose after a plug. i would not stand within 40 foot of that ultimate fight challange!!!!

How do You prime ? Water in the hopper or the groutport ? Maybe with a 3" endhose i plug... I have 10 liter water in the groutport when I prime , rpm 1150 volume at 3 (putz 46-5 , 140 m3/H) When the mud has come over the top I stop the pump and it will go nice and easy when it falls down and "lubricate" the pipes and the endhose. I pump near Norways border and some time it is Norwegian mud for the windparks they build and I think the mud is the same which side of the border it's made...

Look a mobile face fuker!

Totally agree with you Dipstick. What's the problem with an s-tube? Just pump so slow that the concrete is falling gently through the s-tube. If the flow stops switch of the pump, take some strickes in reverse and check what's wrong. If you can't mannage that you shouldn't be driving a pump at all! 3,5'' endhose is crazy with 5'' pipes on your boom.

I can only speak for My self and I am not kidding.... I can tell You that many pumps in Sweden dont carry a 5" endhose , even less pumps with 5" double ender.... If it aint pumpable through a 4" hose , the RM-plant has to change the mix . All pumpe-operators and pumpcompany must stick together and teach the customers what are pumpable or not , and in wich diameter of the hose. I know some time a mix pump like butter and the next time You plug 10 time / mixer ! But If You dont do it , the company on the corner will do it for free.... And if He is lucky it work fine the first time ! But the Next time the customer will have the same mix ? And it dont work so well ?

The thing that you get rocks first is the just the mixerdrivers fault, not the mix or the plant.
All concrete shall be remixed 2 minutes before you start delivering, and if it's a dry and warm day, get the mixerdriver to slowly start emptying just 'till you get mud in the chute, then remix it.
That way the the mud won't loose any moist on the way out on the last, usually dry fins and chute.
That you get mud from the middle of Bergen is no problem, even 4-5 hours old mud should be pumpable with the right mix.

Hey schwing58, so you can't use your pump as a linepump with 3 or even 2 inch hose since you have a 5" boom pipe? :D

Talking about a hanging hose mate...

That's no problem with the nice mud we have here. Or know how to pump with the right equipment.
A pump with only a 5" double ender and a double S is like giving a mechanic a shop with only ONE wrench.

Pumpnoob.. Are you really a pumpdriver? Or are you just some wiseguy? You know what happens when you have a thin hose hanging in your boom and you get a load of air?

Same thing that happens when you have a double S on there. Already at 4 on a Putz a 4" double S reduced from a 5" endhose will be as full as a single 3.5".
If you pump any slower you might as well use a wheelbarrow.
And a 4" double S is not really small enough for say ICF and no matter how slow you pump you will bash the hell out of the ICF.
And what do you use to pour walls? A tremmie, same stuff really.
And even with a 5" double S on medium volume, say 6 on a Putz 16 cell will struggle to keep up and you will get boom bounce from the hose constantly filling up and discharging under pressure. And a straight 5" is not small enough for that kind of volume.
And what if you get air in that setup? Much bigger consequences than with a small and relative light rubber hose.

Yeah, I'm a wiseguy AND an operator.

Yeah, me too. Think it's time to find a dark hole to put my mixertruck in. Aka. work.
