We need to educate operators ( especially) line pump operators on correct line set up . Steel pipe and bends from backend and in line where possible. If flex blows at the hopper the mixer driver is going to take full impact .And a flex can cause up to 3 times the pressure of a steel pipe . Getting operators to use single ended flex at placement to save less injury if hose whip with blockage. And educating them on blowing the line out with compressed air ( not through flex )
Back end safety is paramount in shotcrete pumping applications Kevlar transition sheath, and ⛓️ chain wrapped to protect mixer truck drivers/ inspector/ testers/ bystanders. High pressure delivery system area needs delineation 👍
I know a common question I get is to do with what looks like cracks on twin wall pipes (usually elbows) and when does it need to be changed (especially if it is still relatively thick) and how to properly test it. What kind of calipers work best? Etcetera
I like the topic of clamps as well. Strength. What to look for and measure especially on the swivelling components and why not to loosen off the tip elbow clamp to free it up instead of taking it apart and cleaning it
Scott, you know i am new to the game but I still see alot of veteran pumpers when under the gun of a plug is not backing off the pressure before un clamping or the realization of the pressure in the hose now more vulnerable to failure then the back end. This would be for the line pump guys
Absolutely!!!! I’ve seen “veteran” guys just backing it up and trying to ram it through….. which always gets my scratching/shaking my head more than a little… You’re absolutely correct and though. That’s supposed be literally day #1 of training, yet so often fall to the wayside.
Blowing out a line pump when you have rubber hoses that can whip around if you don't know what you are doing I've been around PUMP'S since I was a kid of 10 here in Dublin IRELAND and I'm in my Mid 40s now so I have seen a lot and I have seen guys going out on a line pump and probably only been on it for a few weeks and don't understand what can go wrong everything running good until you get blocked by a bad load of concrete or it starts to pop on them and they do the wrong things. You need to know that a good load looks and sounds like before you let it into the hopper of a line pump and new guy's don't know the difference between a Pump mix and a rough mix.
That’s the unfortunate thing, most don’t respect air the way they should until they seen the worst case scenario (which is often too late by that time). I’ve posted a couple of tutorial type videos blowing out with air and still try to put up a “refresher” every now and again. One of the worst areas to become complacent in for sure.
The one thing I noticed you guys didn't touch on when you guys were standing there talking was the safety of The operators The operators are like the other ready mix drivers you guys work too many hours you guys are no good guys need to get rest and I think it's awesome that you guys are talking about this kind of stuff I look forward to your next live stream video take care guys
Absolutely! I’m guilty myself of in the past having worked way more consecutive hours than what was likely safe. Now that I’m older and realized that my wife just takes any/all extra money anyhow, those days are long behind me. 😂😂😂
