Just now saw the last few postings, haven't watched the video in the one before this, because I need to go to bed. It's 10:09 p.m., EDT, and t he other two in this house think I don't get enough sleep.
For now, I'll just note that when I was VERY young and living in the Frankford section of Philadelphia, before we moved to a suburb in 1953 and I turned 7 years old, there was a kind of jingle sung by and/or to us with the line, "CeeMENT MIXer! -- putty, putty!" The revolving barrels we saw, big ones that were parts of trucks and much smaller ones perhaps also on wheels for much smaller batches, almost surely were mixing cement with other ingredients to mix concrete. That was used a lot in that area, for small things like steps in front of row houses -- and also for paving the Pennsylvania Turnpike. I subsequently saw that the New Jersey Turnpike and the Garden State Parkway were smoother, being paved with asphalt, I think. We were used to the smells of creosote from the Barrett's chemical plant and of tar from repair jobs on the flat roofs of row houses.

While we’re talking about mixer trucks, what is really lacking is a model of a front loader, Oshkosh, Terex or otherwise. The two concrete plants in my area have been 90%+ front loaders for the past 20 years.
However, I’m a bit old school myself...it’s not a real mixer truck unless it’s a Mack DM. R models don’t cut it.

GHQ makes a cat front end loader, circa late 80’s. I’m even older school, Mack B’s and International R models.

There has been an excellent resin kit of an Oshkosh FDM mixer, they are referred to as Front Discharge Mixer ( FDM, with the narrow part of the bowl facing the front of the truck above the cab where it discharges the load from, via the chute and is also loaded from the narrow end of the bowl, as is a conventional mixer truck.) It was produced for Masterbilt Models, masters designed by Ralph Ratcliffe, a good number of years ago, little hard to find now! These FDM's were not that common throughout the US, very common in a handful of states, none on the West Coast, many in Utah, Nevada, Wyoming and Wisconsin, Michigan and a few others!!! Oshkosh, Mack, Freightliner still make modern versions of FDM's. Although I am also old school and love those DM's, R models were the backbone of most mixer fleets throughout the country, back in the day !

I believe lars was meaning Front Discharge Mixers trucks, not front end loaders ( Cat, Terex, and others ) but we do need RTR models of them from the 70's and 80's. Old school Mack B's and IH R's were the backbone of mixer fleets in the 60's and 70's as well as Whites and Autocar.

If we're being pedantic: Do the trucks even *mix* their contents? I thought they only rotated to keep the contents from hardening. The contents were already mixed at the plant before the truck was filled. Or? Yes they do. The drum is charged with all of the raw ingredients, and the truck mixes them in the drum. Because it continues mixing "in transit" quite a few of us call them transit mixers.

No they don't. The concrete is usually made at a " Batching Plant ' where all the ingredients are added to make the concrete then loaded into many trucks. The purpose of the rotating bowl ( drum ) is to keep the concrete from settling while it is in "transit " otherwise the vibration of the truck travelling on the road would leave the water at the top and the solids (gravel ) at the bottom. This means the rotating bowl maintains the concrete in a fresh state for when it arrives at the jobsite.

Sure, everyone knows what you mean when you call it a cement mixer, but it is sort of like calling a train a choo-choo. I'm going to have to disagree here. In the early 90s I worked for a construction company that specialized in stone masonry retaining walls. We had a fleet of mixer trucks that delivered mixed mortar to the job sites. To anyone else they would have appeared to be "concrete" mixers but the product they carried had no aggregates in it since it was masonry mortar. Mortar mixer, concrete mixer, cement mixer. Same vehicle. Be pedantic if it pleases you, but you might be wrong anyway.

I agree with Ryan. They can have other uses. We use them for delivering sand/gravel mix to hardfill a hole that has been excavated in a street for pipework. Also for delivering bark for landscaping.

They are not cement mixers, they are concrete mixers! Cement is an ingredient of concrete along with sand, stone, water and admixtures.

Post by calzeph on May 22, 2021 3:19:36 GMT -8
They are neither really. The concrete is made at a batching plant in a bulk lot to maintain consistency, remembering that different jobs require differing grades of concrete ( no, not all concrete is the same ) then loaded into the truck which rotates the mix during transit to the jobsite, therefore keeping it fresh and ready to use. It's a real bitch to use concrete that is already hard when it arrives !

I’d like to see Athearn resolve licensing issues with Mack, to remake those B and R model trucks. Seen enough C model fords.

Post by calzeph on May 22, 2021 3:35:50 GMT -8
As much as I would love to see that issue resolved also, I understand it isn't likely, but we can hope. But don't underestimate both the Athearn Ford C ( like the prototype too many produced, although Athearn promised new body styles, fuel delivery, propane delivery and hopefully a MOW/ service body need these!! ) and the Ford F-850. They are both excellent models.

Now most of the R model Macks are hitting that age. I honestly don’t remember too many R mixers. I do remember RBs (set back axle models). But I’m in PA where they allow heavy axle loads without any bridge limits until you hit 80k. In local delivery uses where the engines weren’t huge and there was a lot of mixer + concrete weight to distribute, plus wanting maneuverability in getting around city streets and jobsites, axle backs seemed to be the norm.

It's a real bitch to use concrete that is already hard when it arrives ! You also get a time on a mix ticket. Some job specs require the truck to be unloaded within so many minutes of water being added, and you can send trucks back if they’ve been sitting too long. Also it should be noted on tickets if additional water was added by the driver, as concrete loses strength if there’s too much water. If they add too much and the concrete doesn’t pass a slump test, that’s another reason to send a whole truck back.

They are both excellent models. I like the “C” model fords, I would like them to make a dual axle model of the C, for fuel delivery, and the wrecker model. Would also like the 850 as a single and dual axle tractor . I remember the IH r and b Mack’s , plus some Whites and Autocars also, don’t know when front discharge mixers started being used.

While rerun of Mack trucks from Athearn would no doubt be a most welcome sight. In western new york in the 70s there were two companies that usex Ford LNTs and white trucks for their conrete trucks. Unfortunately Atlas has the ford already and I think they only ever made tractors so I wont hold my breath for any variety from them

Well, it's better than Boley, Lindberg or Wiking mixer bodies. Most resin models need tons of work and they still don't finish out as nice as the Herpa mixer unless you bring a lot to the table. Until Athearn runs their mixer body again - on whatever chassis they choose (spoiler alert: it won't be a Mack B or R) - your only choice is to fight it out with everyone else over the existing stock unless you can make the Herpa body work. You're not likely to pick up an Athearn Mack mixer for less than a Tangent car and the Ford or Kenworth mixers don't fall far behind. By the time you add in shipping you're looking at around $55 for a Ford or Kenworth mixer and $65-70 for a Mack mixer. Fortunately I'm not modeling a batch plant, but it's something I'd consider if I could get clean Mack R cabs and mixer bodies in bulk.

Classic Metals now has a mixer on there 60 Ford chassis, but it looks quite crude also.

- why won't bring back kits? - not cost effective, most Athearn customers don't want kits
Yet people still keep asking for kits. They keep getting told and it still isn't sinking in. Go to train shows and they are still out there, left over from when kits were produced.
- GP30 need to look into, but don't want to duplicate
Duplicate whos? The GP30's currently out there are 25 year old Proto2000.
