YOU KNOW, I KNOW RUNNING A DOUBLE ENDED HOSE IS DANGEROUS. WE ONLY DO IT ON DECKS, BUT WHAT ABOUT WHEN YOU HAVE A DOUBLED ENDED HOSE AND A TREMMIE PIPE ATTACHED AND YOUR POURING A WALL. YOUR WALL GUYS ARE STANDING THERE WITH A COUPLING IN THERE FACE AT THE TOP OF THE WALL. I THINK ALOT OF YOU ARE ACTING LIKE TEXT BOOK CONCRETE PUMP OPERATORS, WERE YOU KNOW AND I KNOW, THAT DOES'NT CUT IT IN THE FIELD. I'M COMPARING YOU GUYS TO AN ARCHITECT THAT DESIGNS A BLOCK FOUNDATION AND PUTS 4 #5 HORIZONTAL REBARS IN A 8" BOND BEAM. COME ON, YEA THAT SOUNDS GOOD IN THAT LITTLE OFFICE, BUT YOU KNOW AS WELL AS I KNOW, YOU CAN'T POUR A DOWN CELL WITH REBAR LIKE THAT. THERE ARE SOME THINGS IN THE FIELD YOU JUST HAVE TO DO.

I agree with you, ive always done what it takes to "GET THE JOB DONE".

 your asking for trouble i started this a long time ago about 5" double ended hoses got my arse chewed i think were friends now!!!!

lol I love you guys. Dont worry, i love talking about this stuff. If we talk about it we are at least thinking about it.

YOUR THE MAN TODD, I CAN SEE THAT SMILE ON YOU FACE WHEN YOU READ THAT.

There are some that are,and some that are not.Now what am I talk'n about? pump operators.Granted there is more forgiveness with a 5" hose,I will  give you that.Yes,you have mud that is course beyond belief,however.I ask how many states you have pumped in?There is a ton of difference between the east coast and west coast,north to south.Somewhere there was a video of a 5" tip blowing air,think the old pumpco parts site.

Personally I could care less how many you want to mame and kill.You can bet one thing,I will testify for the prosecution.Some may learn,others may not.

Brundage made a video of hose whipping after plugging up with air.  Also had a live shot of a real whipping on a job during a column pour.  Todd might want to see if Brundage Safety will let him post it on the board again.  It is a real eye opener.

I respect your comment,east,west,midwest,done there,all up to the operator,atleast when im the only one on my pump 3 hours away from the shop it IS my decision.What is up with the pink lettering?

It reflects my sensitive side,not.I wouldn't worry about the color of my script,rather keeping safety in sight.One wouldn't use west coast gear on the east coast,well the smart ones anyway.I can see it all now,John Q newbi watches Ricky racer do it so it must be ok,right? Not

Any one need a concrete pumping saftey officer? I have seen it all and don't mind being a prick when it comes to saftey.

Not saying double ended is the right thing to do Mr.Sensitive,but if you been pumping concrete for anytime at all im sure youve done it before,OOPS maybe not,you sound like Mr.PERFECT.So go ahead and tell me im a rookie and im not a good operator.Have a good evening got to go spend time with the family,hopefully i will read your great comment some other time.

Wow I am hated already that didn't take long. Why the negative comment guy?

i was going to pour with joe and carlina floors tonight...bet you can't guess what going to be on the end of the pipe line

Okay here's the truth , I used them for years Never had any problems but after people started dying because of them I only run single ended now , now you wanna talk dangerous let's talk reduction hoses, but nobody will standup and do anything about them because there's money involved.

Using a double ended hose is just dumb,first thing when you are pumping a wall its easy to get the darn thing hung in the rebar one hard yank and the guy on the wall falls,a cut rubber end want get stuck.

I'm with you Nick. On the job is a different then in the books cause most contractors dont want to wait to hook up the proper way because if they havent seen it then the hose whip theory is full of shit. I have been running single end but if anybody says they havent ran one their full of shit. I cant count how many times I've had to explain to contractors about the dangers of it and many other things but they dont car cause its about time and time is money. OPerators need to try and watch what there pump is doing so they can hear or see their pump. Adjust to the situation and never leave your pumps side. Its like a kid and it does what you tell it to. Pump on.

Don't kill me for this but I think there's alot less risk running double ended 5inch hoses but in my opinion and for everyone's safety I would run a single ended hose. I've had a linehand who probably thought I was full of shit when I said this job can be very dangerous and unpredictable til the other day, he was shocked to see how the 3inch single ended hose whipped out of his hands when a big piece of dried up concrete went through and got blocked up nearly at the front of the hose, there was no time to stop. It just whipped out of his hands and sprayed concrete on the finishers, I've warned him to be alert and prepared for situations like that. He now knows what it's like when something like that happens. Thankfully it wasn't a high pressure line pump.

For everyone's safety double ended hoses are a no no. I've never seen any whips with anything bigger than 4inch but probably eventually will in my time. But if those persons wants to run double ended hoses it's their choice and everyone's lives is in Pumpers hands. It's a very big risk to take.

It's just a small risk. A risk so small that we should be willing to take it as we look at what other risks we are willing to take in life.

For example:

Lets BAN all fireworks RIGHT NOW. about 10.000 times more people globaly get killed or seriously injured of that than of double ended hoses and fireworks don't serve ANY purpouse besides enjoyment.

O. but wait. Fireworks is legal so then its not our responsibility so than its ok???

Fireworks comes with warnings, so does pumps.
How many pump mfg. or pump organizations endorse the use of metal on your endhose? ...None I know of!

Oh, and fireworks IS banned in some countries. Lets just hope pumps don't.

It's just a small risk. A risk so small that we should be willing to take it as we look at what other risks we are willing to take in life.

For example:

Lets BAN all fireworks RIGHT NOW. about 10.000 times more people globaly get killed or seriously injured of that than of double ended hoses and fireworks don't serve ANY purpouse besides enjoyment.

When one becomes an owner and pays these redicules priemiums I might consider listening.Untill that time my employees follow my sop,plain and simple.The ones that choose not to listen are sent to the unemployment office.

"Get It?"

Many - as Rod Serling would say "We have entered into a plane of twin universes"  You cannot teach those who will not learn, but I applaud you for trying.

Yea.. You are right Many. I know. Why take the risk when you don't have to.

But you must admit there are a lot of things in dailly life that are a lot more risky and nobody cares about those.

If the manufacturers would come with a good shut off valve in the last pipe of the tip section (so just before the last 90 elbow, intergrated in the boom) I think a lot of operators would quicker swich the end hose to a single ended one. Specially the big pumps its some trouble when you start with a single ended and half way the job you have to take on some extra hoses. It can get messy when you don't think a long way ahead.

Yep,a challenge of sorts.Take a look around ones shop at the operators on hand.Now try to figure out the ones that truly get it and you would trust to make the right moves.The numbers are scary once thought out.This industry was so caught up in a feeding frenzy economy that if a person had a pulse,tell time,they were a pump operator.

I personally feel that only about 25% of the ones operating are a operator.This is not to say bad people,just really out of there element.There are people from all walks of life and different backgrounds,just trying to make a living.Then the ones that are cocky and aregant and know it all.

Today,in this economy it's an employers market,the best of the best have work.I for one would look for one that has sound judgement,experience,mechanical skills,growing from there.The owners,managers have a difficult choice ahead,who stays and who don't.I won't go into my insurance costs,but,nosebleed comes to mind.

So,when reading some of the lame things you see here just keep in mind.Without insurance we can't run our companies,sad,isn't it.Take a look around at your companies risk exposure,one fatality accident can put a small company out of business.

Have a safe and enjoyable weekend

Schwing58 , build one or buy one and mount it before or after the 2 last 90's..... We do that on our pumps .

One after with 3" hose on , mounted after the start and no mess...

Yea. I know those. They work great. But they tend to break quite easy when you have them down on the ground with a lot of line. I broke 2 already. Not by moving the boom, just spontaniously. I'd rather have it in between the last pipe of the tip section. But not sure if that's possible. (And it will wear out quite quick i'm afraid??)

You can mount it there You want , cut the pipe and weld a new flange....and keep the cut of pipe as a backup if the aircuff breaks if You dont have a spare one with You... My ones use to hold for 18000-22000 m3 of concrete .

I think i'm going to try it. Thanks! You have convinced me vasa :-) 18.000 is not a hel of a lot though. I pump about 40.000m3 a year...

Buy 3 direct then or start making theme self . More money to save if you make theme self... I have about 2.5-3.0 bar of compressed-air in the valve and about 4 seconds of delay of the start of the pump after "starting" to pump so the air has time to go away... If you have "vector" on your Schwing all that is in the vector-system .
