New type of ready mix lorry?

@Loading shovel hired/borrowed/scrounged one and made a YouTube video. He shone the camera up into the workings so you can see what happens.

Haven't they been around for years

At least 20 years. Got some concrete in the yard laid in 2004 with a volumetric mixer.

Found it hard to have enough water on them to do a 8 cube mix on a warm day.

Who were you using, few round us, some very good others less so!

Tried several of them over the years mainly manor, (There are several more local since then) The last time one came out I sprinted across the yard and grabbed a mask and the driver said ah you've had one of these before, It was enough for me to realise they must always be dusty. I found it hard to get enough water in the mix without it being slop for certain projects when you need it right its to difficult for a volumetric I never bother with them now they are not as timely as premixers either for the very reason they do not know how many cube they will be mixing up on sites, by midday they will be all over the place, you needed to be pre 10am.

We did a floor which required 3cube a day for 16days I paid the part load charge on a 6cube premixer because there's no way four people could trowel concrete inside a building with all that dust more so it needed a good consistent mix which wouldn't be achievable with a volumetric

Laid a fair bit off volumetric mixers stour never a problem. They do have a wee plastic tube on the end of the cement auger though, I could see how it would be dusty if the cement wasn't funnelled down to the auger.

I'd be interested to know if they make a sufficiently consistent mix for structural engineering projects.
CYO Seeds run one out of their Lutterworth depot, but I personally think the system is better suited to messing about jobs, odd bits, etc, rather than say a big floor or a yard slab.

Interested to hear your opinion

They’re ok. As everyone says they have there place.
You have to keep an eye on the mix, doesn’t take much for stone hopper to get a bit of a blockage and then your concrete becomes grout.

@Loading shovel is the man to ask

I’m going to say I probably wouldn’t want to do any more that a 20 cube pour with one the concrete that comes out is fine the problem is because it’s not all mixed at the same time like a barrel mixer one side of the slab is going off while the other end is wet

Volumetric mixers have different weight limits compared to standard lorries. Which is why they can carry more.

8 wheelers can carry 20 ton ,so about 16 to of material on a volumetric

if you're wanting a big mix can get them to turn up on site 'dry' and fill with water on site.

Argue with the government if you believe you are right & know better. Tell them to sort out their website & have it say what you think rather than what they think…

Currently seems like its still under review as to whether they make it permanent. It reads as if some, previous to this review were running to the maximum weight on the plate of the individual lorry.

We had a problem with our local vcm company, they were loading to the extent they were shedding aggregate at every corner, police paid them a visit. They were loading way over 38.4

 

[Doing it for the kids]

Anything built after 2018 apparantly can’t carry as much.

8m3 all day now

Yes we use them for small jobs but the wetness can be a bit hit and miss I prefer premix for bigger jobs. But I was told the other day the volumetric ones can hold a lot more cubes as they can go overweight as they are in a different class than just haulage like cranes etc I’ve no idea if that’s true or not

 

[killie_cowboy]

We've used volumetric stuff, my uncle in fact runs a company thru in the west with a good few of them. The stuff isn't just the same quality as the stuff out the jiggers, but its fine and can be adjusted on the fly and never noticed them being particularly stoory.

 

[snarling bee]

As above they are ideal for what I call 'farm jobs'. A large slab though we use barrels.
Our local volumetric lot are great, good drivers, plenty of time, and I think will often do a slightly stronger mix than spec to save any issues later.
If we only want a cube or less they will often call in on their way past and give us a good rate.
They will also lend kit if required, which is helpful.

I saw a video of an American mixer where the barrel was on the truck the other way round. The exit point was just in front of the top of the cab widescreen and the chutes were hydraulically controlled. The driver stayed in the cab whilst unloading and was able to place the concrete where it was needed more accurately and could easily move sideways a bit using the steering.

I have never seen any other type in person. The volumetric are around in some places. And the rear discharge are around on bigger highway jobs etc. But every one I've ever seen has been front discharge as you describe.
