Even though in all my years of pumping I havent had any problems with double ended hoses our company will institute a new policy of not pouring out of double ended hoses as discharge hoses,I would like to thank this site for all of the recent discussions on the subject which has enabled us to see a growing problem in the pumping industry,one that we do not want any part in so as of July 1,2008 we will no longer have them hanging from our booms in a effort to control accidents and save lives I would like to issue a challenge to all pumping companies that frequent this website to do the same,out of everyone that opposed this I was probably one of the most vocal, I correct myself and have to say I was wrong and was just lucky no accident ever happened while using these types of hoses,now up next is reduction hoses,if we get rid of double ended hoses I would have to say our next fight will be getting rid of these accidents waiting to happen, being all of my reduction hoses have been put away in the do not use area, I do not have to worry about them,I hope you all will see the light as I have and move towards a change for the better, Thanks concretepumping.com for making this company a safer one.

Thanks Pudg,

from my limited use of them,less than 10 i've had two whippings on a 5-4 that came on our 2 38zs after those two i knew the odds weren't in my favor your reduction should always be contained in metal ,in my opinion,maybe its the mixes down here but whatever it is I had less safety issues with my double ended but those days are over and hopefully the days of the reduction hose and the danger of it is not to far behind

 I believe the kind sponsor needs to be notified on our stand on reduction hoses.They are located over

i second the motion on reduction hoses. the big problem with them is by the time you hear the plug it's already too late. the last time i used one it plugged at the end, and being a soft rubber tip as opposed to hard inflexible steel the obstruction came flying out hitting a laborer in the chest. i'm sad to say he doesn't work anymore due to internal bleeding. it was a baseball sized chunk of re-claimed concrete from the ready-mix that made it into my hopper. and i'm sure the velocity of that chunk was if not greater, than equal to a fast pitch at close range.

I went home and have made this picture on a building site there stood putz 36м. Double ended 5"hose,reducer,double 90!!!

Guess I'm lucky my old pump doesn't have the pressure of the newer pumps. I generaly pump at 100 yrs per hour pace or less. my reducing hose has packed twice in the year and a half i've had it..  Just a couple days apart-and same ready mix supplier (no surprise there). Both times I heard pressure build and stoped it. I was very surprised by the effert it look to beat the plug out of the hose with mini-sledge. 

  I make it a point to try not to out pump my supply. Yes I know batch-plant will try and use your pump pace as excuse and say they batch to your pace-- so you have to walk a tight rope here but no sence in pumping wide open if you don't need to.       Stay Safe.
