Since you are sitting there reading this and have nothing better to do [because you aren’t working enough] I would like to ask you a question and have you give me your true opinion on this matter. I am doing a “Bob reality check”

Question:  What do you think of an operator that uses a 5x4 reducer as the discharge point of his boom?

It is hanging off of a 5” hose.

Thank you for your opinion ;~)

I also like to tac weld some nails and spikes on the end ;)

wow a junior high education and a CDL license and look what you got a boom pump operator that knows how to connect a five inch clamp.

Freaking retarded and should be fired on the spot.....

Why in the world would you even consider doing such a thing,Even a green operator should have sence enough to know better,And if not SHAME on the guy that trained him...I always tell every one NO STEEL on the tip!!! I would give a new hand another chance! And maybe fire the guy that trained him!!

if he/she  has been on here then they have no excuse now or in the future, but there is a whole world of uneducated folk out there, blissfully unaware of how times have changed.

I pick answer C = Stuipid

Other than the obvious reasons I would love to see this operator be a hose man for about 200 yards.

I say he isn't stupid just maybe ignorant to the dangers, I have seen many operators do the same its no different than the famed double 90 a fatality waiting to happen, so many dangers reduction hoses,double 90s powerlines we just arent educating operators the way we used to a pulse a cdl and hes a damn fine operator with a week of otj training, with these prices what did you expect a real operator on your job they are getting what they want to pay for, shitty service,shitty equipment with a truck driver and a remote with a 100' death stick shoving 100yd a hour of concrete thru it,its just the way it is wake up america its 2009 and its gonna get worse wait till all this repoed iron hits the market at these cheap prices its really gonna get dangerous out there

oh and nice to see the blue writing back over here ,Bob

today a hose whip happend and a guy got knocked out and another guy got his arm broken. Good news is no metal at the end of that hose. Just think how much worse it would of been if they had a reducer, double 90 or a metal end.

hey bob good to see you back on here. as to your question if a double ended hose is a hazard, just think what would happen if you had a momentary blockage in the  5 to 4 reducer that broke free before you could back off the pressure. on second thought ill take answer c like Many. doing that is a recipe for disaster. hey Bob you talked to Ant lately?

I thought I read a post a while ago about hanging a reducer from a 5' length of 5" boom hose for placing concrete in form walls around rebar but I may have read that wrong because I can't seem to find it anywhere in the previous posts.

If you want honesty, when I first started pumping I was shown to use a 10' boom hose to a steel reducer with a double 90 on the end of the reducer. That was what I was shown and used for a while until I joined this site and started reading many of the posts and topics. Today I reduce with steel right off the tip to a 4" hose or I use a 5" to 4" reducing hose.

I pumped 1 and only 1 slab with using just the steel reducer and no rubber hose but only because the finishers helpers were not around. I would pump for a while then stop and wait for him to screed it off then I would pump a little more. I made sure nobody was anywhere near the reducer before I would start pumping. Everything went smoothly, but I haven't done it since and I don't think I ever will. Not sure about the safety aspect but it was one of the slower pours I have done.

Not sure if this is what Bob is looking for but my fingers just started and couldn't stop...lol

 Lets not forget that a long time ago almost every boom had a five inch tip hose instead of elbows with reducers on the end of it.

 It's still totally Stupid and dangerous!!!

 I can see it happening on a rig like the one shown below just because the dumbass was to lazy to put his whip on...

TT,I could have sworn those came from the factory 4" booms.

i read some of these stories and I am glad we can talk truthfully on this site I have done just about everything previously stated, we was trained to get the job done with far less powerful equipment than we have now the post about shooting concrete 30 ft man even if it is laid down(i have done this) how much more dangerous can we get ? this site is about educating so lets start schooling , metal on the end no matter what the reason or purpose unless its a trimee pipe is a unacceptable practice,we have graduated from getting the job done no matter what,lets getr done safely,if I saw one of my operators do this he would be home for atleast 3 days 2nd offense termination , pumping concrete is not worth injuring or killing someone , it can be done in a safe manner ,so what if someone has to bring you a hose if the finishers have to pull some mud we all go home safe and at the end of the day thats all we can hope for,hope you all have a great weekend.
