Just another example of us risking our livelyhood because the customer demanded it. When will companies stop doing crap like this? When the tip hose and safety strap fail and it kills 3 people? The tip section was removed from this pump, making it ok per the manufacturer. I would love to see that letter. Does that sound right? Hell no! Do you think Conforms would provide a letter backing up their products and taking responsibility if they were asked? Tip hose, clamps and safety strap ect. rated to hold 1600 lbs....? I think not. Good job pumper. All done for prices cheaper than what we pumped for in the early ninties. Customer probably saved 20k on not having to use a crane.

I lost this job because i refused to be unsafe. Am I thinking clearly on this one?

Like to hear everyones thought on this...... Thanks

What an A-HOLE!!!!!

All In,

I have a letter from the manufacturer stating that we can hang 1500 lbs from the end of the 3^rd section of a 34 Meter.  With the modified tip section, 10’ 5 inch hose, 36” 5-4 reducer, clamps and a 40’ 4” pipe; filled with concrete the total weight was 250 lbs below the limit.  The tremie pipe was attached to the boom with cables so no load was imposed on the hose or clamps.  The project was completed safely and without incident.  Judging from the picture you posted you know which job I am talking about.

Why don’t you fill out your profile so everyone knows who you are?  Why are you hiding?

that's quite an assumption you're making there?  How do you know what he's charging?   to remove the tip involves a cost, it also removes the pump from doing other jobs. 

I don't agree with all that weight being borne by the clamp and hose.  I do like the idea of the last section being replaced by a stub, but IMHO, the pipe should not continue on the stub, a hose should be fitted from the last straight pipe on the original section to the hanging wall pipe, and a chain/cable system rigged up to support the weight of the wall pipe to the stub.  The hose (A la dayz of olde booms) would allow for many degrees of free movement of the wall pipe.  Do you get the picture?

There is a certain risk in having a boom pump and crane connected by pipes, hoses, etc....and who is liable in an accident?  If you can remove one variable while increasing safety or reducing risk, it's a good idea.  But obviously, they needs to be a monetary payback for modifying equipment and reducing the useability of the equipment for it's main intended purposes.

The pipe is hanging in two chains in the last short section , not only in the short hose and clamp... Putz has sold some booms like that , they showed one at Bauma 2004 or 2007 . And in Putzmeister-post they show one to , but I dont know in wich nr . So I think everything is ok , but I'am not sure before I see some document from the manufactuer of the pump .

I'll buy that this one is hanging by 1 chain, I doubt by 2 - there's no point, it can't hang straight anyways, with the pipe offset from the stick.

I like my idea of a longer hose with the tremmie supported by chains (or cable) off the stubby tip so that it IS centered, and to have the hose loose to allow a good bit of freeedom of movement.

Chris, like this?

No chains and a hose as flat as a pancake.

Better pick of it

http://www.putzmeister.de/pm_online/data/PM_3879_GB.pdf On page 15 you see what i mean... I will try to find a pic of the boom-tip they showed at Bauma , it had two chain that hold the pipe or hose. One on each side of the pipe in the center .

Chris, I have no reason to hide.The pics i posted look totally different than what you described. Maybe I'm confused. Hope all is well in Houston.

 Well the most I have ever free held is a 25" dont know if I would do a 45" unless it was light guage.

Corby,

The pictures you posted show nothing more than what I stated in the earlier post.  The tremie IS attached to the modified jib with cables.  As for your confusion, you will have to be the one to answer that question.

I am glad to see you filled out your profile.  I had an idea, but without knowing the facts (unlike many who want to post on this site) I wasn’t going mouth off without verification.  I believe that people who hide behind anonymous screen names while bashing their competition are nothing more than cowards.  If a man has something to say, he ought to be man enough to let everyone know who is saying it.

Things are good in Houston, about to start off on a new adventure.  Thanks for asking.

Why don’t you post pics of your pumps on different projects instead of pics of your competitors?  That would make more sense to me.

Justapumper,

Yes it is light gauge, and yes it was approved by the manufacturer.

I have used the system that you are talking about chris and it is the best and the safest thing to do good job chris

Putzmeister will sell you the contrtraption.  Capable of hanging 60' of 4".  Call Don Gerou at putz.

Funny how there are always people that think they can just sit and wait till all the easy jobs come and the customers will roll out the red carpet for them. And when there comes a competitor that does a bit more effort or has a better attitude or price they start complaining he's a a'hol. Maybe they should look in the mirror instead??
