[@canadianconcretepumper1979]

@@robertaustin-y7j I’ve been working with our finishing guys a good bit more as of recently. Truthfully, the finishing was always our break and butter, the pumping for years was just there to supplement on own finishing crews, and then around the late-90’s/early-2000’s sort took on a life of its own. I really enjoy being out with our guys.

[@nolanu2393]

This video gave me flashbacks. Used to work with a plant that had course sand and not many fines. They used a lot of the sand in the mix to. We eventually decided it was the sand. We looked at everything on the pump. Alliance even flew out to do a pour and monitor the pump. It was so random when it would do it. But the worst was always residential jobs pumping slow. Or lots of stoping and starting style pours. Anyway the eventual solution to a load like that was reverse 5 strokes at full volume. (With Alliance we couldn’t easily run the cylinders right to the end like a putz.) The idea being that broke everything loose in the end of the cylinders/S-tube and we could usually pump out at least 2 meters before it would act up again. Could at least get that load pumped off that way. Anyway I’ve never heard of anybody outside of the Lloydminster Alberta/Sask area have this issue.

This is an employee who operates a pump in Korea. When starting work, is there a high risk of concrete clogging if you set up the 1st, 2nd, and 3rd stage booms and start with the 4th and 5th stage booms gently bent at an angle of about 30 degrees from the horizontal? If the boom falls at a steep incline, there is no problem with starting, but if two or more booms form a gentle angle, this seems to be a major cause of starting failure.

[@canadianconcretepumper1979]

@@FIL_to_the_MOON Really lots of variables to consider here. The way you mentioned is undoubtedly the highest rate of success in getting it through. With our materials, priming this particular machine in Z-formation has a very high rate of success. We also find some benefit in priming through in a Z-formation (less potential for trapped air in the boom when stretching out and commencing pumping after the prime. For a newer operator or an operator lining a harsh mix, I would reckoned A-frame. For 95% of what we do, Z-prime has its benefits.great comment, and a great discussion topic.

Looked like a gravy mix when you had the line hooked up! Nice solid stream, and good arc! Do you guys move the air cuff often to prevent the stubby 5’ from getting soft in one spot?

[@canadianconcretepumper1979]

@@derkaderka5910 so weird that we didn’t see any issues pumping the mix until Alana’s precisely the moment we transitioned to pinning straight of of the boom. My suspicion is that a load or two may have been slightly off. Great question about the air cuff. So what we have found with the newer style fabric cuff from ConForms is that it does not create soft spots in the hose like the old hard-shell style cuffs did. Those older ones we had to be diligent in but always having the cuff pinching the exact same place on the hose pour after pour. The new ones, when used with a quality hose, we typically see the metal end wear through before the cuff ever causes issue with the rubber.

@@canadianconcretepumper1979 the fabric cuff is the way to go. It would be nice if they had more wear resistant attachment points though.

the groaning noise may also be the holding valves, if they are counterbalance "cartridge" valves they can back off sometimes, and cause a groan or squeal my bucket truck had a holding valve do this, it started as a groan, then a squeal (really, really loud squeal), then eventually the boom would randomly freefall 10-15 feet, tightened the valves back up and no issues since

@@danielcotton-pm6tw it’s becoming more common these days to see contractors with washout pans on site, but the majority of residential contractors prefer to pay the hour of pump time + $250 disposal fee for us to take it away, rather than dealing with the mess left on site.

does using the aircuff damage the hoses?

[@austinpalmlund5054]

The fabric cuffs don’t seem to cause any problems with a good quality hose, however the older style cuffs with a hard outer shell will cause soft spots over time

[@canadianconcretepumper1979]

@@TheQuantumFire the old hard-shell style cuffs would kill a hose in a matter of months. The newer, fabric cuffs I have worn through the metal coupling end of the hose before the hose itself ever succumbed to the effects of the cuff. That being said, it is still critical to not run the air pressure any higher than needed to stop the flow of concrete. Also, engaging the pump before the cuff has released and the hose has fully opened WILL kill the hose in a hurry. Just a little bit of basic diligence and they’re less detrimental to the hose than kinking it off and throwing the old-school rope around it.
