My camera on my phone is playing up, so there will not be many photos for a while, but one of my supervisors carries a camera to most jobs, so I got him to send me some of his photos

Jonna,

Love your pics,I have a problem with one.On pic three you are sitting on your pipe.Man please never sit on your pipe.If that thing blows you will be picking rocks out of your ass for years..I'm not picking on you at all.I'm just tring to save your future family.I have seen it done.It is not pretty.

Just a thought.

Keep pumping

Ruck

DITTO!!

THANK YOU

Yard Whore

It  seems to me that in picture 3, you are sitting on pipe while pumping, or so it appears.I guess it is a matter of preference really, but I always like to be standing up for a number of reasons when pumping. One of which, is because I want to see the pump when possible,and the entire crew is up and working. Picture 4, I guess there are 2 pumps there?, looks like another set of system in picture. I usually will sit when waiting on trucks though on a deck pour. I Don't want to get to comfortable when actually pumping though, alot to keep an eye or two on.

looking at picture 4 though I know bringing that tip hose down and leveling it somewhat will create alot less surge in the system. I would have tip 90s about 1 meter off deck, unless there was some reason contractor didn't want me to.

or some other reason that I don't see in pictures.

Thanks for the advice guys. I will pass it on. I wasn't on that pour, our supervisor took the pictures.

What size pump it that?  The chassis looks awful short to have twin steer. 

And that turret is the closest to the cab that I have ever seen. 

I was also wondering why there is no rebar in a lot of the areas?  All those conduits create great spots for cracks to propogate from.  Just wondering as to the reasoning. 

I think it's a post tension deck, why there is less rebar, don't think that is all conduit. 

hey pumpjockey, the pump is a Schwing S47SX on a Mercedes actros chassis, I am not too sure on other states and territories, but in Queensland we have to run twin steer due to our department of transport having strict weight laws with this type of vehicle. You are right about the turret, it is very close to the cab, Mercedes actually lowered the roof to accommodate the boom overhang. Rob W you are right, it is a post tension deck or stress deck, all the conduit is protecting very strong steel cable which runs the length of deck into junction boxes, once the deck is cured they tension the cables to form the main internal support structure for the deck.

OK, 47M, a cab crusher, so lots of weight over the cab. (and front axles)   Kinda cool that they'd mod the cab.

I haven't had any experience with post-tensioned, so that's why I didn't clue into it.   I know what it's about, just never seen one up close in person.

Our Pipeline on the pump is tested every 30 days manually with calipers. We rarely blow a pipe, the odd pipline manufacturers failure/defect.

Temporary static line is tested before use also. Sitting on the pipe is only a concern if you are a company that pumps unitl it blows then replace it or make it a practice installing the bare minumum pipeline as its not as heavy to lift in to place.. We replace well before and destroy pipeline that has a chance of failure.

If there is a risk of the pipe blowing and injuring a person sitting on it, is there still not the risk of it blowing and hitting any standerbys or workers in close vicinity.

 if this was a concern then should not all pipeline be contained in an exclusion zone.

Instead control the risk of actually blowing a pipe..Set a minumum thickness benchmark suitable to the job at hand.

I do agree that the operator must have clear view of pump and workers, so if standing facilitates this then by all means.

But im not the Work Police, so if the worker needs to sit because his legs are tired by all means do so. Fatigue is far more fatal to decision making than forcing a worker to stand. Especially considering these guys work through many meal breaks and might start at 4:30am
