Before we start this topic I understand the safety issue of both. I have never used the hosecuffs and skeptical about them on how well they work. What if you tap rebar with the air line will it release or has anybody ever had one not work properly like when your over someone (super, hehehe)? I used shutoff clamps and made them pretty full proof. Never had any issue (yet). I understand the weight on the end can be like a headache ball but its not much different then a load a craine is swinging. It to can be eradic. I believe that by having it wll make you be a little more carfull when you move the boom. Which is good for most. Much luv to my fellow brothers and input back on the subject is appreciated. Anything negative towards me will not hurt my feelings so judge yourself before you judge me a fellow pumper.

Air is much safer than a mechanical blocking-thingy.
Air cuffs uses just 2-6 bars of pressure, so when concrete pressure rises over that it will just bleed through safely.
Mechanical just goes boom when it reaches a point.
As for safety with cutting your airhose on rebar I've never had a problem, I use steel braided hose and tape it to the safety chain of my boom, wich also extends to the air cuff wich is only a meter or so after last 90.

Takes a bit practice to fill columns and stuff all the way to the top with air cuffs and still get the hose to run dry.
As for drips I just stuff a ball in the hose.

here's a nice one for you guys. I showed it at another topic already: I understand that in the US this thing is completely out of the question? Its a 'double 90 with a lock which the hose man can close himself. Gives you the opertunity to poor extremely acurate. Like on a few m3 inches. Great for some purposes. And the pump operator never gets the blame when pooring to much. It saves a hel of a lot of eye damage aswell. It comes naturaly that the operator has to focus a lot more when driving this thing. Just make sure you dont make the hose whip and pump slowly. Also, when the flow stops while you are pumping you know there's something wrong. When the lock is closed make 100.000% sure you dont pump. If doubts, just reset the whole thing!! I actualy think its no problem to use it when you know what your doing. (not for new beginers!!!)  Feel free to copy the patent. Remember to donate a few bucks to my acount!!  ;-)

Patens on that ( we have used that for atleast 25 years) and like PumpNoob says the air-cuff is more safer and You learn to shut of the pump in time , I have run with air-cuffs for 16 years and no accident or broken air-line. We must have them on State-job , and most contractors demand them . Have You once started to use on You never go back !

I, too, in Italy I have already said that we use every day ... it just takes attention to use it and everything will be 'perfect

This works gr8 for me never had a problem with it just make sure you don't pump with it in also it doesn't work with grout but works awesome with crete.

Air cuffs work great!, I use it almost everyday... I would strongly recommend using a rope as well if you are swinging over anything critical eg.. cars/human beings... On our Putzmeisters if you turn the engine off (or hit the engine kill by mistake) you have about 5 seconds before the air cuff opens up by default.... you don't want to learn this the hard way..... like I did :(

tne airbags schwing provide r awesome and stay shut even if engine is turned off.a minor cut in hose still feeds enough pressure to keep it shut but still good idea to kink hose if you feel there is a dangerous situation.if u smooth like the legend won't even come close to reo.already made comment about that column pourer they r accident waiting to happen.

We rewire our Putz so the air-cuff stay cloesed if the engien stop , like Schwing has .

i have only used schwing air bags and only once seen it fail once and that was when the air line blew off the fitting.(this was on a pump that i dont go out on offten and when i checked the hose clamps had come lose and the reg was jacked up to high) so the best op i can see is use a kinker as well as your air bag and keep it safe for the others that work around you

I was ofcourse jocking about the whole patent part my friend. I use an air cutoff aswell but this thing beats everything when you have a big boom. It wasn't my invention but the compagnie i work now uses it and I must say.. I don't mislike it. 

A friend of mine makes them and they are far better than any that are made by anyone or any company Vasa you know who I mean anyway if anyone wants one send me a pm and I will give you the info. The best part is if you have any issues they are delt with right away you are not left hanging

Conforms has a manually controled one. The hoseman runs the valve, it is run down from the Air Cuff to where the hoseman can reach it.

lol we dont have those round here! All we do is kink the hose ,  never have a problem ......

Drew it is 2010 if You dont know ! You run a pump on modern Volvo FM , 6 stage boom . Why ? Old things are better . If I knew , You could bought our 32 years old Scheele on a Scania , 24m 3 stage... ;-)

Hey now! Sheele's good iron!

I didn't say it was a bad pump , only old ! It was a "Goldmine" !
