Yes, I attach it to a double ended hose and put a rubber hose over the metal parts to keep it safe.

You could also put it on a single ended hose if you carve out a strip in the rubber from a few mm. This way the iron ring on the plastic cone can fit in to prevent the cone from coming down. 

I've put a video on you tube as well: http://www.youtube.com/watch?v=kHeJ_PyKe9A

This is a good idea for Quadlock or styroform walls that require consistant flow and is a better alernative than a dangerous double 90 flow control. In the US hanging a double end hose is a big NO. Most contractors wont have it and profesional concrete pumpers dont even consider it. Simply covering a metal end on the discharge hose does'nt make it more safe, but it might reduce Blood loss a little.

 Your cone is probably safer than the fools that do this..... 

Too tall, I agree with you about the metall on the end hose. Too many people got injured or even killed from uncontrolled hose whipping. Over here most people work with a 100 mm end hose end a lot of them with double ended hose.

A few years ago a collegue of ours lost his live. He was listening on a double ended hose for the concrete to come when he started pumping. The hose blocked up, the pressure raised and the blockup released with enormous force. He got struck by the hose in the head...

I searched for a system that is safe and still keeps the clients satisfied cause if the concrete splashes all around you don't have to come next time.

I use a 125 mm end hose. There is no reducer on the boom so blockups don't often occur, especially not if you compare it to the 100 mm hose. If there gets a big stone in the cone it will open. If the rubber cover on the metal parts is thick enough it will proctect from injury. Putzmeister have got a system where they put a reducer on 3 metal pins and cover it with rubber and a system to cover couplings with rubber: both are aproved by the german Berufsgenossenschaft concerning safety on concrete pumps.

However, it's possible to use the plastic cone with a single ended hose as well and of course, no metall at all is safer then metall covered with rubber. 

When you were pumping with the Steady Hose, was it 125 mm or 100 mm?

I think is some kind of "textilfibre" or composite fibre.... But it works well , if You pump without a hoseman and it hangs free it is more steady .

I will do a "traffic-cone"  to My 5" endhose and test it ! Lokks good !

The traffic cone is an interesting solution to a problem. The way it is configured – with a two ended hose is not acceptable at all. The way it is configured goes against our stand of NO METAL on the discharge hose.

When this or a similar device is put on the end of a single ended ANTI WHIP hose, then we might be closer to a way to not only stop the hose whipping but the splatter and control problems as well. Our inventor needs some help to tune up his device.

It sounds like VASA is going to do just that. Hose manufacturers are the ones that should be doing this research

Good luck V, and be careful out there ;~)

Bob,

I've got already a solution in my head where no metall at all is involved. Will work it out as soon as I got the time and post some pics.

I agree totally with your point of view on double ended hoses. We can't be carefull enough!

On the other hand, if the German association for safety has aproved the Pin Pour system from Putz, they must have tested it very well because I know those Germans are very strict on safety rules.

Even a single ended hose is still steel wire covered with rubber...

If the single ended hose gets blocked and the pressure releases with a power of 10 Ton, the impact will be almost as destructive.

Anyway, the safer the better. I will work on it till I find a solution that meets the requirements.

Bob, I think it's great what you and all the others do to make our industrie more safe. By sharing our experiences we can avoid a lot of damage and find solutions to problems related to concrete pumping.

Bob I have not sleep tonight , thinking of different solution to do it wihtout some metal... But I think I must use some kind of strap to hold it , and it is a little metalpice on the strap but some rubber over it so is that problem solved....

But I am in the schoolbench this week so it take some weeks before My version is coming , but i like the ide´ with a traffic-cone ! And that model of cone is going out in Sweden other things is coming , all this thing from EU !

Vasa,

I will make a rubber piece on the hose where the cone clips over to keep the force going down, to prevent the clip to open horizontally I will fix a strap without metall.

What do you think.

It looks loke a good ide´ !

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

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.

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
