Saw this as I was headed to Tampa, off of I75 around Big Bend Road, snaged this pic on the way back.  Its a hose to reducer to another hose being placed by a guy walking on top of the form.  Not gonna name the pump company, but we tried them once, and our Super kicked his ass off the job in the middle of a pour.  Didn't think this was legal.  

Looks like there is some kind of fence of some kind of scafholding behind the wall. The higher wall also has a fence on it. Can't see whats behind that one. Just from this picture I can't see much crazy stuff. But I wasn't there.. Only see this picture..

Thats the rebar for the wall.  It is hard to tell from the pic, but like I said, its hose to a reducer to a 25' hose.  I thought you could not hang more than 10' of hose from the boom.  Even still, when I went by the first time, the guy looked to be walking the form, and from what I could tell, he had a remote in his hand too.  

When we pump 30 ft walls we hang a 20 ft wall pipe off of our booms all the time u just tie it off and put spikes through the clamps the key to it is haveing straps !

Short answer NO there is excessive end hose weight for MOST concrete booms.  

On the end of most booms is a decal that has a Max end hose load rating, this could be in Kilos of Lbs. Depending on the size of the unit and type of boom this number varies a bit.

This is the MFG max allowable weight on the end of the boom.

This number is not different if the Jib or end arm is straight down.

Extending the load can cause unseen damage that might not fail today but can affect the integrity of the entire structure.

This load rating is also connected to machine stability.

The rating includes all items hanging from the end of the boom, Hose, Clamps, Reducer, AND Concrete inside it are all totaled up to the load allowed on the boom.

This doesn’t even take into account of the potential Hose Whip if it plugs or gets air in the system.

Good Pic not showing the MFG or customer, And this is a good topic to talk about, adding extra weight is common practice in the industry and Not approved by Most Mfg’s.

Just because this has been common practice and done by a lot of pump companies does not make it correct or safe to do.

If you are unsure as to how much weight you can “hang” call the MFG for your unit, it is a big thing.

If that already is to much hose hanging from the boom we have a big.. no.. HUGE problem in this industri...

 There is a weight rating for the boom. so what was the size of the hose. you can hang a lot more 2" than 4".

Yes sadly this is a big problem, It is also the one no one wants or likes to talk about, it will take a large effort in the pumpers AND contractors comunity.

With the pumps getting longer and lighter this comes into play a lot more than the old heavier units, BUT even they had limits that were ignored.

And that makes a big difference. A 4'' hose takes only half the volume in concrete than a 5'' one.

It would also be nice if the mfg would give better info. Like a sheald on the truck that would give the max tip weight or something.  

And a 3'' hose takes about 5 times less concrete per meter than a 5'' 

Its funny if you think about it.. We can asume that any boom can handle a 5'' endhose of about 4/5 meters long. So that means you can conect 25m of 3'' as long as you are not to lazy to take away the 5'' endhose.. 25m thats 27 yards. Quite a lot !!

This will help get a estimate on hose and material weight.

seems like that need that to pump few feet at a time seen this many times n yes its safe to me now to many no but don't seen thing wrong with this n well all n fl can tell who it is
