Pumping a 50 storey high-rise tower.

[@ConcreteFloorSolutions]

Another great video. Back in the 1980s I pumped many high-rises in Philadelphia using a swing 650 trailer with gate valves and 6 inch barrels. Those gate valves would have to slam so hard to stop the back pressure. Technology has come such a long way. We used to use what we would call a go devil, which was a black rubber piston with an air compressor. It was always quite a show at the end of the day. There would be a cage we would attach on the end to catch it when it came through.

[@canadianconcretepumper1979]

I was out in Toronto just last week and most everyone there blows back into the mixer and uses a cage at the end of the pipe to keep from losing the $100 go-devil. To my knowledge, the black go-devils are a more rigid version of the blue ones which we use. Less forgiving, but do a better job of getting the pipes clean.

Wow nice 360, progress in every direction, unbelievable the growth going on there.

[@canadianconcretepumper1979]

It’s a double-edged sword. Fantastic in terms of available work, but not so fantastic in that our region has really lost all sense of community with this added growth. Can’t have it all I suppose.

Gidday, love the channel.Pumped concrete in Adelaide Australia all with putzy booms. 32 roll, 36 roll 36z and the best one, yes a 28z with 12L module and elephant trunk. 12 litres per metre at 5" pipe 2556 Litres conc 2.5m3 Keep pumping

[@canadianconcretepumper1979]

Elephant trunk, damn!!! We had a couple of those in our market back around the mid-2000’s. The guys who ran em would always say the harder you pumped with them, the smoother they would get!

[@newrealm9187]

Good stuff again scott!

[@canadianconcretepumper1979]

Thanks buddy 🙏🙏🙏

[@egancraneriggingservicesin9142]

thats impressive, never seen how it is pumped that high,

[@greghughey9738]

Rock being a pourous material, and pumps being piston driven, when we pump chem mud, the tiny amount of water its batched with is forced into the rock quickly. The Couture was 80+mpa(12,000psi) core, all chemical. 5 gallons made almost 60 bar difference in piston pressure. Crazy what they have us send up 500'+ the horizontal, and the 38m on top 😂😂

[@canadianconcretepumper1979]

We were in Toronto just last week watching a 14000 push 70-ish floors. Makes this 50 story seem entry level. Those 14000’s are absolute MONSTERS!!!!

[@greghughey9738]

@@canadianconcretepumper1979 Was it pre-emissons? The post emissons 14k has a much quieter exhaust note, almost none compared to the earlier versions, but the fan produces a much higher pitch tone thats seems almost louder. I'll def keep the pre-emission version lol

[@bowenike]

Meals has a video of the water washout on their youtube channel I believe. Its a super old video, could definitely use a refresh produced by you 🤣

[@canadianconcretepumper1979]

When chatting with the Meales guys at World of Concrete, they had mentioned that the video currently up on KZbin is quite old/outdated and they’ve tweaked several things since then. We’re hoping to become well versed in their most current method of water-washing. I can see many benefits in terms of cost saving to the contractor, as well as improved safety for the pumping company (us).

[@RenewedLifeMedia]

All I hear when you talk about this 13hpd kit is, Oooo putzmister you make such good pumps ill say whatever you want whenever you want for a sniff of a brand new 28z. I bet the alliance comparable would be just as good.

[@canadianconcretepumper1979]

We’ve been using Putz pumps for 25+ years (long before KZbin). Alliance makes a great pump, but they currently do not offer a 28Z with short-rig stability system, hence why the Putz 28Z is what I want. FYI: We had a Schwing 31XT on order in 2022, but had to bail on it in the final hour due to lack of operators. If something is shit (Ergo 2) I’ll say it’s shit. End of story.

[@canadianconcretepumper1979]

Out of curiosity, what’s your experience with concrete pumps/pumpinhhs? Your channel appears to be all 3D printing???

[@RenewedLifeMedia]

@canadianconcretepumper1979 starting in the pumping industry next week. Been cramming every bit of information you have about pumping the last few months. Love the work. No disrespect for your love for putz they're amazing bit of gear.

[@canadianconcretepumper1979]

@@RenewedLifeMedia Most excellent. I only ask because I was curious as to your experience with Alliance pumps. My buddy Dann (in a bunch of videos) ran a 12 cell high-pressure Alliance pump at his previous place of employment, he now runs a 13HPD Putz and says it vastly outperforms that Alliance. That being said, Alliance now offers a 14 cell high-pressure kit which should be comparable, or possibly even more capable than the 13HPD Putz. My buddy Morrie (also in a bunch of videos) now has one. I actually have a video coming in the next week or two featuring it. I’m eager to see it plugged into a 40+ story high rise. Full disclosure: I’m 100% biassed towards Putz as that’s what we’ve always run and what I know best. But I do appreciate certain makes/models from most every major manufacturer. I WANT THAT 28Z PUTZ!!!!

This will be a two part (saturday/sunday) video. In my opinion, this is the best video which I’ve ever done. I’m excited to share it!!!

Wow the views. I think the camera has seen better days lmao. Loved the video carnt wait for part 2

[@blue-collarbangin]

9.49 inch slump. Holy Jesus that's wet!!!!!!! How is the aggregate not separating pumping that wet, that far, that straight up?¡!! That's wild

[@yotaforlife8408]

I've pump 40mpa with high early many times and have never been allowed a 240m slump by any engineer

[@canadianconcretepumper1979]

We’ve seen some pretty wild slumps here in recent years (especially for the placing-boom high rise work). It seems that same type/quality as well as fly-ash grade have changed (not for the better). We’ve had projects in which it was testing at 180mm at the pump, and coming out the end of the placing-boom on the 25th floor at an 80mm. It makes for a fairly interesting day indeed.

[@stevethomas4095]

We also blow back into an empty mixer

[@robertaustin-y7j]

Hey Scott I know this is an old video that you made a couple years ago I was just wondering are you still going to keep making them are you still guys going to still have the live chat what's going to happen with the whole situation this year

[@canadianconcretepumper1979]

So I think the plan with the live chat is to have one day every 3-4 weeks, speaking of which, we’ve got to get something lined up for within the next couple of weeks here.

[@stevethomas4095]

Oh by the way we run our diverter valves off the agatater circuit

[@canadianconcretepumper1979]

We keep these packs on site as it opens up options for if we have to use a machine which doesn’t have the compatible fittings, or any fittings at all.

[@austinpalmlund5054]

Does the pipe on the placing boom need to be high pressure rated as well? Love the content

[@canadianconcretepumper1979]

So no, but… that’s a bit of a loaded discussion which would be great for a future livestream. Most modern high rise pumps have means of limiting pressure as such that when the building is still at its lower floors, the 85 bar rated boom pipe is not incurring pressures beyond its allowable limitations.

[@eddieleon39]

No bentonite for priming

[@canadianconcretepumper1979]

You will not hear me say this often, but…. No, no bentonite on this one 😂

[@Mike-b3v]

3.54 cement in pipe Or 2.71 cubic meters

[@stevethomas4095]

A really good operator would know how many strokes it takes to prime I use to count them. That tells you how many yards you have in your pipe line. We have one going in Denver right now if you want to take a peak.

[@TheQuantumFire]

Is there back flow prevention on the vertical pipe going up the building?

[@canadianconcretepumper1979]

Negative, just the valve in the hopper.

[@Gillies02]

Dann would tell me to go eat a burger or something whenever he used the remote after me, if dann you see this you know it’s true

[@canadianconcretepumper1979]

After spending several days with Dann at Canadian Concrete Expo, I have come to the conclusion that he actually does not eat between the hours of 12am-6pm. Mind you, he would likely say the exact opposite of me 😂😂😂

That does not look like a 9inch slump. My eye test would say maybe a 6-7” slump. Obviously the tape don’t lie though. A 9inch slump id expect the mud to act like scc at that point.

Alll the chemical additives help keep it together, despite the slump. Too much science for me 😂😂😂

@@canadianconcretepumper1979 ah that makes sense. Also, how long can you sit not pumping with all that system full before it segregates and plugs up

[@canadianconcretepumper1979]

@@falcone2307 Typically we will hold a truck at the pump once it’s down to 3 cubic meters remaining. We’ll pump a half cubic meter once every 5-10 minutes until the next load of concrete arrives on site. If we end up having to sit for more than 10 minutes without moving mud, it’s because we done screwed up somewhere along the way.

[@stevethomas4095]

You must be a Putzmeister sales Rep.

[@canadianconcretepumper1979]

It may sound like it at times, but we have been close to trying other brands before. Putz has always taken care of us and typically had the best machine for our specific needs. Parts and service support are also strong in our area, which is probably the biggest reason why we’ve stuck with them. If you watch my videos however, there are a good number of non-Putz rigs on my wish-list as well (Schwing 31XT and Liebherr 36-5XXT being very high up there). New generation Putz 28Z with full-flex support is probably my number one though.

[@canadianconcretepumper1979]

I do firmly belief they make the best high rise pump, although we do have a 4800 Schwing hopefully going onto a high rise job very soon here. Opinions always subject to change 😁😁😁
