Certainly not new by any means.For the non believers,one kneecap pays for itself.

how about replacing the elbow when it's getting thin?

In all fairness,as all pumps are not created equal,same applies to operators.If it was that simple they wouldn't have the nets.

not to new have used for years.

anouther safty product by BBCP.they have been on the tranition's of are pump's for year's now.they do work!

Why let it get that worn out? Let me guess!

About safety how is it possible that pump is pumping whit the grate open????

same sediments super d .

Here we go again.. Right on the face...

This is a readymix drivers dream. He is the guy standing there not knowing what condition that pipe is in.

That's true... But I could never get my boss to buy one for me.. I asked several times for a Pin Poor for example.. I just don't get it.

But we just got a new daily leader so there is hope.. He seems very in to safety..

Like the music !! Like the product!!

Mixer truck hit transition and a couple trucks later it burst, Ugly.

Wouldn't a big truck tire tube do the same thing?

Perhaps,if one has a needle and thread

Looks like an older unit dont think those had the safety switch on the grate.

Safety switch ore not the grate is open

As the guy who did accident investigations and handled the lawsuits for a couple of the manufacturers, I can tell you that sometimes the transition pipes blow. Sometimes it's because of lack of maintenance, sometimes from an impact crack (truck hits the pipe), sometimes it's from a faulty casting...but in ALL cases, there's a ready-mix driver back there, or you wouldn't be pumping. That's why the 'pipe diaper' is required at the back, but no place else...it's just a matter of exposure. The last accident like this I investigated happened in the SF bay area; two ready mix drivers were injured. They both sued the pump company, the manufacturer, and the contractor. You could pay for every pipe-diaper for every machine in the fleet FOREVER with the cost of that one accident and still have enough left over to pay cash for a new house. This is the textbook definition of a 'no brainer.' Just do it.

why not run it on entire pipeline if you want to be totally save, from my experiance pipes and elbows will blow anywhere on the boom why should mixer drivers get special protection and not anyone else?pipe thickness testing and proper maintence should suffice.still a good idea though

While I agree that this is an idea that serves a good purpose, judging from the pressure behind the big burst it appears the line may have been clogged and the operator was trying to pump it out, which is almost always a recipe for disaster. Unless there is a plug somewhere I don't see it building up that much pressure no matter how fast you're pumping.

As pumpco had a great vid on hosewhip,they have one now on the safety net.Why would one wish to question the designed thought.The net does in fact stop the projectile,yes Dorthey,that means the rock.Some here have seen the result of transition failure,best discribed as horrific.

Uncle Billybob once asked,how much does an accident cost? For the misinformed operator (loosely put),who cares,the owners should/do care,they write the checks.

I addition they're pumping air like hell which makes the effect of the blow even worse... But I just heared about a deck pipe blow a few weeks ago in spectacular fasion.. Rock flying 20m high.. So it can be extreem under the right conditions..

Call me the bad guy. But if you keep a yardage log and check the wall thickness of the backend and pipes when lets say changing gaskets on the boom or orings in the back end and replace with new when they reach the critical stage you shouldn't need this product. Not looking for a fight just my two cents.

I for one wouldn't want to bet the whole deal on number counting.I will give you some,records are wonderful tools,however should the product fail prematurly.Long ago we started producing transitions and 6" elbows.Then the worst started happening,failures.So when one installes a new anything,don't assume.

Many are we talking bootleg parts or OEM?
