Todd,

This is a "super-Boom" or Texas-Boom"

This practice is outside the compliance of the Pumping Association and the Crane Association.

It is too easy to inadvertantly apply a side load, or an overload to both the crane and the pump boom.

This practice benefits only the contractor and puts both equipment and job site personnel at great risk.

This is a very good picture of what an operator should never do!!!

I have used one of these before on a bridge deck,I agree with Bob not a very safe practice,to many players in the game 15 yard penalty.

Yup,one time back in the early 80's.That was pins and needles.I would be interested to know the date of picture.I thought they got away from that long ago,guess i'm wrong.Looking closer it's a newer pump.

I only wished more operators could see how these newer/lighter booms are made.Everyone keeps talking BIG boom lenghts,it comes with a price.The metal is thinner,the reenforcement gussets are placed in positions just for this.

In most boom failures they have found it was structually dammaged on the inside (never seen) first.

1) Good pictures.

2) Good safety for boom.

3) Good communication between crane operator and pump operator.

   I know that ya'll don't want to hear this,but,If I was told by my boss/owner to do this job in this particular way,I would do it.I would probably put 2 hoses between the boom and crane to give the two booms more "differential".I have done this in the past with no problem.Now on the other hand if my boss/owner told me to boom close to power lines I definitly would not do it.Now for all you naysayers,if my boss/owner wants to bend the boom,let it rip.

Well the one thing i know is that Pumpcrete is a great company. They have operators that have been with them forever, once your in with PumpCrete you are a lifer. Oh and Ken is one of my best friends. (sorry ken)

Here is the video i did for PumpCrete

I actually lost a job about seven or eight years for refusing to do dumb shit.  Pardon my language Todd but doing this is ten times more dangerous than running any double ended hose.  As long as people do things like this (one wrong move with either the crane or the pump the fourth section can fall off and kill everyone on the jobsite)  I have personally witnessed the fourth section fall off through two floors of a deck.  Please dont do this anymore whoever you are.  Note I said please because I dont sign your paycheck or feed your family

Todd,

Seen them done them think they are over the top unsafe practice. I havent had to do one of these types ofjobs in quite awhile. When I had to they were usually because they didnt want to run system across their post tension cables or run system period. I had always tried to talk them into a mini placer to keep sustem off the deck but usually it fell on deaf ears. Thank god I dont have to do that crap any more. Just because it could and can be done safely it should be strongly discouraged. There are other and safer ways...

Todd,

dont believe everthing these guys tell you . I do this all the time with cranes and my pump. if you are an experiebnced pumper as i am an many here arre . this is text book safe. show me where it is against the law. you just need to know what you are doing. boom tips just dont fall off that easy

STUPID! just plain stupid. run a system or crane dump. What ever you do, dont call me.

in south carolina we call them getto booms

awesome . i love when people get creative

Has anyone ever done a caisson with a crane assist taking the load of 80' of tremmie pipe?  I don't like it but that's how it's done.  So what's the difference if the pipe the crane is holding is horizontal or vertical? 

Did you notice the safety straps on the hanging hoses?  The pictures depict a well planned out production - not something that was thought up that morning in the job shack, 30 minutes before the pour,  over some stail donuts and coffee to help ease the hang-over.

Again, it's not my favorite situation - but sometimes some good planning and creativity can yield great success.

There were too many mishaps while using this device. The crane association and the pumping association both decided that it was best to take a stand against doing it.

Now that we got that out of the way... I agree that the people that planned and executed this pour knew exactly how to go about it. The spreaders on the crane are all well within a safe angle, the pipe looks well fixed to the spreader beam, the discharge elbow on the spreader is supported and safety straps are evident.

My guess is that if everyone that attempted to make one of these pours was as professional as the pump and crane company that did this one; the professional associations would have taken a different stance on the subject.

This is a text book application.

The company that did this, (hope they still like me) owns cranes and pumps. Believe me when i tell you they have their act together.

When i worked at Burndage Bone we did this on many jobs for one customer.

Hey Guys.....yes, I've seen this too....a company here in az loves to do this.....they made me on an job near sky harbour for the rental car center.....the first day it arrived the crane manager refused, basically cause it had no engineering specs....I hated it, cause half the time i was the one shifting it back and forth.....a few times got into a bind with the crane.....we pumped 1,000's of yards thru it.....tweaked the heck out of the boom on the 61, then they tried blaming me....they claimed a local company always let them use it, but brundage can do what they want, no me.....luckily i eventually left the company and had no further part of it

Tood.  new to site AWESOME  ive been concretepumper for 32yrs. seen alot of SHIT DONE we had a contractor from minn. come to chicago with this system 10yrs. ago. ive pumped thru this for 9 floors except they had a tower crane.toomuch work&RESPONDABILTY FOR THE OPER. we are abig union city(local 150)chicago found out later due to pumping gave toomuch stress oncrane boom cable .boom(200ft) long.tower crane mfgr. local said NO WAY...this system never used again.[ook at 3 hoses hanging by 1clamp anda little lip HDend NEVERAGAIN.
