Mack DMM W Theam conveyor

[gotnitro?]

well guys, its been a long time since my last build. My wife and I was blessed to have a beautiful baby girl enter our lives!! A few months of getting into a routine..which  I never thought would happen..well our little angel sleeps enough to grant me a few hours to build.

This time around, I'll be building  a truck commonly seen around our  roads. This project is fun for me since the majority of the needed parts are available thru the AM, and I wont need to fab everything.

The list of goodies includes- DM 800 mixer Frame, resin Mack 6 spoke wheels, MTM McNeilus mixer mastered by Chris Davis, cast thru AITM trucks. I'll be using a Mack 690 cab from GW trucks..and a few surprises along the way. The major part for me is the scratch built Theam conveyor belt .

The main reference Ive been using is riding along on a Paystar..

I started by mocking up the DM 800 frame..which everyone here has seen..so pics wont be needed! I left off the fish plates so the new Mack camelback suspension Gary Wallace has, will properly fit the frames.These trucks commonly had double frames, and the mixer kit has these already. Adding the plates made an almost triple frame much heavier than the truck I'm portraying.

I started the main mount for the conveyor  using .030 sheet. A few Meng bolts will add details later.

The "Maxi -Pivot" arm is a focal point on these truck. This arm carries the entire belt on a chain driven , rotating arm. Normally stowed/ folded along the side of the truck , once at the jobsite, the operator will remotely unfold the arm, pouring the cement into place keeping the truck a distance away! Watching the driver curl the arm , reminded me of a scorpion.

The arm was built using the fish plates, and laminated strips . Using pics, I later sanded the taper and profile into the  main body.

 

The conveyor pedestal came next, a few hours later I had this..a working Maxi Pivot arm !!

 

Thanks for looking , any feedback welcome!

Jeff wow this is a very interesting truck. I have not seen this type of cement mixer or heard of them. Do you have any information on these trucks?

your build is looking good I will be following to see what you do with it.

NIce work Jeff!  Will be watching progress!

Thanks everyone, I appreciate the feedback !!  I had a surprise last night while working on  a few parts. My little girl came and hung out , so I stashed all the toxic stuff and found a few toys for her to play with.

Dan- about the truck, the DMM is usually a twin steer heavy duty truck. They also built several in single front axle, but normally all have all wheel drive capability. This truck is a 6X6. The Theam conveyor is a bolt on rear mounted assembly, allowing more flexibility to placing the cement. The unfolded belt on this model is around 40 ft. The cool part is the ability to swing the entire unit getting into tighter places then a "normal" mixer allows.

I just received a large box from Egg Harbor so I'll have another update shortly

Jeff you know by now that your life has changed fore ever.  All for the good enjoy your time with your daughter as they grow up fast. 

Thanks for the info in the Theam conveyor  looks  like it is very effective way to place concrete. I'm used to seeing concrete pump trucks used to make long reaches. I checked out there web site and checked out there trucks.

First, congratulation to your beautiful daughter. Make sure you keep all the modelling stuff out of her reach. Your work bench might be a great attraction for her. But Dan is right - they grow up fast.

Your project is very interesting. I cannot remember ever seeing a mixer with the belt conveyor. But they are over here in Europe too. Though. the concrete pump is more common, I guess. This work body sitting on a Mack chassis is a perfect combination. I cannot wait to see more but I respect your Jennie´s right of way.

   Jeff,

         Congrats an your baby girl . She is beautiful !

As I said before I am looking forward to following this thread  closely. I have never seen a mixer with that type of delivery unit.

Though I have seen a similar thing on the back of dump trucks. The closest to that was on the site mix trucks that had a screw

  delivery to a short chute.

 

 

    Be Well

Congrats on your new addition to the family!!!!! The truck will be fine, your beautiful daughter requires your attention!!!!!

[gotnitro?]

Thanks everyone,  I keep all the dangers picked up and the room is upstairs away from her ...for now! 

She certainly makes sure to grab my attention every chance she gets. ..I think I'm trained already!

Congratulations on your beautiful daughter! When my oldest son was born 11 1/2 years ago, I gave up model building for a while (too many irons in the fire) and didn't start back until a couple of years ago. Glad to be back to building though.

You've got a great start on a great project!

What a beautiful baby girl...congratulations!! I'm looking forward to this project and what you've done so far looks real nice.

[gotnitro?]

Thanks on the comments about my daughter,  she's been keeping us on our toes! I forgot what 2 hrs sleep felt like...finally sleeping a full night!

Glad everyone likes the progress,  I started the first of the 3 folding sections, basically just square tubing for the boom body and telescopic tubing for the hydraulic cylinder that extends the sections . Found a couple pics didn't show the detail I'd hoped, so it's back to the plant !

Congratulations on the beautiful baby girl!This will be a great project!

[Andrew Howard]

Congartulations Nitro on the safe arrival of your daughter. I am looking forward to this build,great work so far.

[gotnitro?]

ok, back at it !! sorry for the long delay..I've been busy getting the major parts built.  I needed better pics so a visit to the repair shop luckily had a conveyor apart for maintenance the first section had  the "head roller " rolling on bearings..so..I made everything I could

 

thanks for looking!

ok..now skip ahead to the "folding section" I call the stinger. Here we have the driven main roller, the side plates, and support framework !  All these parts were built from images from pics Gary W and I have  taken, or the parts manual..

I used plastic tubing of random sizes based off the images,

once I had the "stinger"  length I wanted., the center section was next !! Square tubing was used for the main boom w a smaller size inside for added strength . The accessories were added then my favorite part ..MOCK UP !!

[gotnitro?]

lurking in the background, you"ll notice the parts for the next step. A few tubes pretending to be cylinders, flat strips for plates..and other bits. glue together and its ready for another mock up !!!

 

That's it for now !!! thanks for looking !
