Do it like the pro's, no metall on your discharge hose.

There you go baby! Hey look, hose-man with no remote box! ha,ha. After your last post (the one with all the big red writing) I thought you might have been angry. Its OK I get very angry also! I have shot (2) computer monitors since I joined! HA,HA,HAA

Glad to see you're improving your device. You can call it the "Flow-Cone"?  Pump-On Kris!!!

Hi Too Tall,

wasn't angry. Just wanted to make some contrast to all the reactions.

I can understand them but I regret that on on the safety issue most of the replies just say your crazy and it's unsafe.

That I'm crazy, I knew that for a long time so I didn't need this site to find that out.

But on my arguments why I'm doing this and in which way it can contribute to safety if done in the right circumstances and with the necessary concentration, I get little or no detailed response.

Anyway, I agree that it's safer to have a good hose man on the hose and a good operator concentrating on the pump. The problem is that we don't always have a good hose man on the job site...

I've tried to put a video on video.concretepumping.com and I follow the steps to upload it but it doesn't appear. Don't know what I'm doing wrong.

Anyway, here's the url for youtube: http://nl.youtube.com/watch?v=QC-VYo7c3OQ

I have to say I think you may be on to something! It looks like a 5" tip hose. so a 4" tip hose may bee a significant improvement to your device! This is a great alternative to a double 90! How often do you use it, What do your customers think?

Customers think it's great. I use it all the time.

It is indeed a 5" hose. Before we always used a 4" but you often get plugs in the reducer, especially since a lot of plants started with recycled concrete. They crush old concrete and use it in the production. If a long small piece of concrete passes the grid it will probably make it to the reducer and then block up the line. If the pressure raises and the plug releases you've got the equivalent of a canon ball coming out of the hose. Many accidents happened because of this among which a collegue of mine loosing his life 5 years ago.

To find a safer solution I started working with the 5" hose. The problem is the splatter when pumping at low speed. Therefore I came up with the cone. It gives a continuous flow and no splatter even if you pump at low speed. If there is a bigger stone, the cone will open and the stone will pass.

Did you cut the end of the cone off and then put slits in the sides?

Yes, I did.

Great idea Kris!!!! what keeps the cone on the hose?

My thoughts exactly! I went out today with my cone fixed it all up like you said. I attached it with tie wire and gorilla tape. Primed out. It looked awesome. Flowed out smooth like a 3". Unfortunately when I  started pumping the wall it fell off into the wall? No one cared I hope it is not sticking out the side when they pull the panels. Lucky for me it is back filled in and out.

We need to know the secret of keeping it on the end of the hose.... with no heavy metal. ;~)

The problem is of course how to prevent the downward force pushing off the cone with no metall connection. After the first post on this topic you pointed out not to use metall for safety reasons and that was also my concern so I started searching for alternatives.

For now I just use plastic straps, the ones electricians use to bundle cables. A few around the hose and three going down works fine to me. Make sure you make slits in the side of the cone: in case the pressure raises the cone opens instead of coming down. If you start pumping, don't pump to fast untill the first concrete has come out. And in case of a block up it's better for the cone to come down then having the hose flying around under maximum pressure in case the plug releases. If you try it out, I suggest not do it on a wall till you got the trick so in case the cone comes of you won't lose it.

I've got something with a velcro strap but it still needs some improvement. I'll post pictures as soon as possible.

Here's the beginning of an idea? It will require some field testing and may require (2) of these but its pretty simple and light. It would also eliminate having to cut a "groove" or alter the hose in any way. You will have to click on the image below to view full size....

hi Tootall about the 1 reply

I know Kris for a long time and i have seen him angry not often,maybe a little bit disappointed;

instead the lovesickblues he got the concreteblues

you can't fix that with 1 bottle Jack Daniel's

Kris just set your ampli On 10  and pull these string's

Keep on rocking

DapperDan Sir, There is a simple solution to any problem that is not fixed with (1)bottle of Whiskey.........Get another bottle  !!! 

I've put another video using the cone on my website. You can see it on www.concretepumps.be on the page End hose reducer.

Here's a picture of how I put the cone on the hose at the moment: just a few plastic straps. It works fine but I'm working on something with a velcro strap to put it off and on more easy. I'll post the pictures as soon as possible.

Kris.

The cone is a nice cheap idea.To prevent downward force with your cone ,how about using a large gauge rubber o ring glued to the hose about a foot up then tie off above that with ties or rope?? The o ring could stay as part of the hose .

How about an open ended sock or condom made of velcro to secure the cone to the hose.
