We were looking to add 40 ft of reach 1 90 sweep and19 ft stab pipe to a 50m. All of the pipe would be 5". What would be the safest way to rig the to a crawler? Also so can a trapeze be use in a vertical application. PLZ post links and or PICS. TY

Maybe something like this??

Nice Picture Dipstick

Nordic misunderstand ( slow pumping to a crawl?} maybe if that's what you mean, drop a gear and pump slow?

Yes this pic helps alot dip. Do you need a counter weight to balance the stab pipe?

Now this is frowned at, I will find some papers on doing this sometime today. I know it can be very dangerous and can hurt the boom if your not careful

Make sure you read this

You better reed this one. Before we start al over again.

You don't need a counter weight.. But what you need is a good cranedriver that does what you say. Have good radios.. He should not be pulling to much on your boom. And take it easy with the pumping.. Otherwize it might be bad for his crane.  I talked to a guy from potain.. (A big crane manufacturer for if you don't know them) He said its no problem to do this as long as you take it a bit easy..

keep in mind these newer booms are made much lighter,meaning more flex and easier to damage.The damage may take a long time to surface,months or even years.

It is indeed very important to not do this cowboy style.. And make sure the crane operator understands that. But this pic was me some weeks ago and I had the endhose hanging nicely in this bend all the time. You can quite easy see if you are pulling in any way.. I would maybe preffer a pump under 45 meter and a bit more system in the crane. Pumps over 45m are quite weak in the tip section specialy sideways.. But than again.. I would be comfortable doing this with a 52m also..

I use 4'' pipes in the crane. I would do that if you can.. Safes almost half the weight..

Whit our indepent crane boom you can keep your hose on the deck.

Hose on the deck al the time.

But personal I prefer this one. Les stres for the operator.

I did read that other blog and Ty Todd for the info but this is the only way we can place this concrete. I wish there was a larger footprint for a 61m. I feel that this means of pumpin is safer then short sticking out riggers. By the way we are working with self consolidating concrete in a wall so the crane would only need to move up and down.

Cool Cool my friend, we are all praying for you. 

That kind of concrete might give you an extra challange.. Than it would be an advantage with 5'' all the way. Otherwize if you stop and some part of the system starst to drain you might get a litlle get to gether of rock down in the pumps endhose for example..  Start pumping again and you've got a plugg in the 5-4 reducer.. And that would be quite irritating in this situation..

We were using a Pipe Spreader on one job that had a big footprint.  We used it several times on the job, so when we finished pouring, we laid it out in a field and would get it when we were ready to pour again.  The next day we all showed up and lifted the spreader up on the deck and hooked it up. When we primed out a skunk came out of the end of the hose and landed right in the middle of some freaked out finishers.  After everyone stopped running around, they put a bucket over the skunk and threw it off the bulding.

Back then we were just starting to use the pipe spreader and we would hook them up to anything from hydraulic cranes to conventional cranes.  Now a days, depending on who you talk to, they don't suggest using a pipe spreader at all.  At the least they say use it with a tower crane only, because of the surge in the system.  I'm not sure if they've had any accidents, or damage, or what.  Years ago we just placed the concrete anyway we could.  Just make sure, like dipstick said, make sure you have a bend in your tip hose,and the hose that hooks up to the pipe.  Turn the volume down, and make damn sure to have good communication with the crane operator.
