Dont Down the Man!!!  Lets Teach Him The Right Way To  Pour It Out!!!

 Yeah to pour a freakin SLAB Too!

The PDF file there is a part that says use double 90's on the end of a pump line wow lol.

WOW lots of you pumpers out there really have an issue with the use of the double 90 or double ended hose I really think you all are really out to lunch.  How about this lets use the reducing hose that is not steel lined but has no steel end on it and lets have a plug in the hose and lets have that hose explode while in the hands of the hose man instead.  I will take a double 90 on the end any time.  I have seen them reducing hoses kink on a wall pour never used it again for that and have heard of some horror stories of reducing hoses exploding. 

Northern Pumper you are the one out to lunch on this one. I know of a accident several years ago in Northern Cali where a very experienced operator didn't shut off his pump in time. People heard the plug and took off but as he shut off the pump the plug came loose and it looked like the hose witht he double 90 honed in on one laborer. The double 90 hit the kid at the base of the back of his neck and paralyzed a 23yr old from the neck down for the rest if his life. It took hi years to get over it. He still gets choked up when the subject comes up. And this was a seasoned vet that never pumped who never pumped fast.

We here in Italy there is a law that prohibits the use of the double curve that only 90% of shipyard wants a matter of convenience'.... and as you do what the customer wants to use .... Always carefully ....

Northern:  Reducing hoses are steel reinforced.  At least the ones I know you're talking about [click on con forms link]  I have used the buffers as well and have hated those heavy swinging things since they came around.  You have also seen it on residential where they pour so wet the concrete comes out spinning.  Listen to the rest of the world there son,  everyone else can,t be wrong just because it hasn't hapeened to you or I,  even though I have been close a couple of times.  Even without hose whip from air or a plug those things are a weapon.  When you get to a site early swing your boom as fast as you can then stop, now hook up your buffer and do the same thing.  I can remember an older gentleman on the hose back in the day of working 20 hrs a day, I was swinging from one outside wall to the other, the hose man was looking at the hose and I was swinging full bore confident in my ability to stop and catch the swing of the hose before it got to him, that is until he bent over to move a jacket that was hung on the wall.  Now I did get it slowed up a bit but he got an awful goose egg on his head.  Point of the story is twofold one is always expect the unexpected and two is a rubber hose would have just bitch slapped him.  I still use it if need be but not using it makes my day easier and safer.  I know it helps air content and splatter but some of those jobs your on up there with their safety policies etc.  those guys will rip you and your company a new one if there is an accident with one and they find out every manufacturer does not reccomend them and as pointed out earlier in some places they are just outlawed.  The new C.S.A standard that is going to be used to try and standardize the industry here does not reccommend them and to me that $pells law$uit.  Sorry man just the way I see it.

LOL. You think that thing is dangerous? Look at what they use in Norway!! Ist a (what you guys call) double 90 (shouldn't it be double 45?) But this one has a lock at the end which can just be closed by the hose man by lifting it out of a hook. Some old ones can even close by them selves when pumping verry hard!!! That means: never take your eyes from the hose and ALWAYS be sure that the pump is switched of when you think it is.

I am from holland and drove pumps there for 5 years before moving to norway. There I worked with it for the first time. Its not my idea but if I dont put it on ill be the only driver in norway that refuses to do so. So no choice actually... 

 Holey piece of CraP! The theory behind the engineering must be to tame the bitch and ride it out when a nasty air pocket comes? It's always nice to have a great big clamp right at face level when its time to hose dance. I've seen tip hoses do enough crazy $hit to add more metal to the mahem.

 I agree that reducing hoses ask for trouble.

 Check out the rocket science alternative to all the above...

Putz has a new "pinpour" now . They showed it at Bauma , a steelrod through the endhose.... Maybee some one took some pic's of that ?

here ya go Vasa

Thank you Boom Inspector , but that is the "old" model . I did not take a photo of it.... It was a steelrod through the endhose about 20"-30" from the end. And I think it was legal buy German laws and Putz . I haven't tested it yet , We use 5" hose very rarely... But I will try one and ask our customer what they think about it . But I have to make some plug when I suck the sponges with water between...

Too Tall, the hill billy duc tape trick wasn't so bad after all, was it?

I've put video on youtube about the cone. You can find it if you search for  flow cone or krispomp.

Vasa, I looked at it from the inside and the outside but I didn't take a picture from it. I'm just wondering what it will do if you gat a block up. Any one tried it out allready?

I looked at it to , I will test it as soon the Swedish Putz-dealer get them or I make one My self...

why not use 85mm/3.5inch hose instead of 5or 4inch this will reduce splash and keep hose full at slower pump speed.that thing from holland was crazy but seen similar in australian but outlawed now.

I have no problem to have a 4" full of mud , even if I pump slow . It was for the 5" endhose I want to test it , and about the splatter , the hoseman will have to use the right clothes and glases. In Sweden when We pour slab or deck and We are member of SFF (like ACPA) We shall have the same diameter of the endhose as the pipeline.

I found the pic , but it didn´t work so well when I shrink the pic...

That doesn't look safe at all!! A pin through the center of a hose? Get some segregated rocky material and it binds up, get a 'cement ball' and it binds, get a chunk of over size or a fin-fish. (like that never happens) Looks like the 'bolt hose' of days gone by, only even more dangerous.

It's tough to beat the traffic cone - extremely low-tech, but adaptable. If it plugs, it rips, self-relieving low-strength plastic. LOL

hehe. Your right. It isn't safe. But it is 5''  . I met a guy today that has his own pump. He made himself a 3'' version of this thing. Real handsize. Thats even more crazy!!!
