Euclid R-62 dump truck
 

Euclid R-62 in scale 1/24

My next project is something completely different. No crane this time!
My main fascination is with cranes, but I also love earthmoving equipment.

The intention is to make this dump truck fully functioning and able to handle tough conditions.

I started with the axles. I will make axles with planetary end drives and lockable differentials.
These are the parts:

Planetaries come from this motor:

The axles are taking shape:

Cool, old school brute. Will be looking forward to seeing more. What scale?

Oops, never mind, you stated what the scale was at the very top of your first post. I was so focused on the photo that I didn't see it.

Re: Euclid R-62 dump truck
 

Wow, this is gonna be cool!

Re: Euclid R-62 dump truck
 

Great project-this will be fun to watch. Good to see scratch building happening again on this site. If this is any where near the quality of your cranes it will be spectacular!!

Re: Euclid R-62 dump truck
 

thanks,

Kerst

Re: Euclid R-62 dump truck
 

This will be an AWESOME project to watch progress along!

Re: Euclid R-62 dump truck
 

I knew you just couldn't resist making one to play on the dirt pile.

Re: Euclid R-62 dump truck
 

yes, I want to play in the dirt.

Kerst

Re: Euclid R-62 dump truck
 

That's gonna be pretty cool.

Ya got him wanting to play in the dirt, next thing ya know a crane is going to be pushed into Dragline or Clamshell operation...

How long are those gearmotors, not counting the shaft?

Re: Euclid R-62 dump truck
 

This picture shows the dimensions:

I hope the gears will be strong enough. we will find out.

Re: Euclid R-62 dump truck
 

A little update:
I build the front axle. Here are the 3 axles lined up.

Re: Euclid R-62 dump truck
 

Your craftsmanship is always superb so this will be another awesome build!
Can't seem to find a spec sheet on the real truck, what are the general dimensions in 1/24th scale?
Sorry I can't make Cabin Fever this year, so won't be able to chat in person, but hope everyone has a great event.

Re: Euclid R-62 dump truck
 

Thanks! It will be around 18" long.

The frame takes shape.

Re: Euclid R-62 dump truck
 

This should be very easy and less time consuming than your normal builds.
(No boom and 500yds of rope):D

Re: Euclid R-62 dump truck
 

Very interesting method of frame construction. How are you holding the pieces together?

Re: Euclid R-62 dump truck
 

With an EPOXY RESIN PERMANENT GLUE.

Re: Euclid R-62 dump truck
 

Thanks for info. I am looking forward to seeing more of your build of this interesting truck.

Re: Euclid R-62 dump truck
 

Amazing work already! Super heavy duty. A question, how tall are those tires, in inches, top to bottom?

(I havn't been around in a while, and then couldn't log in for ever. Finally got in.) Dan

Re: Euclid R-62 dump truck
 

The diameter of the tires is 3 1/4" (83 mm).

Re: Euclid R-62 dump truck
 

Looking forward to watching this build!!! Interesting truck!!!

I made some good progress on the suspension. The front axle is ready, but the rears need more work. The springs are made from worn out hack saw blades. They are very flexible and only the teeth are hardened, so it is easy to cut them.

Really cool looking truck. Great progress so far. Curious it looks like the hubs are plastic? Is that for ease of machining or to save weight? Where do you find details and dimensions for a truck like this? Lastly will you use servo/actuator or hydraulic for dump box?

Looking forward to your progress.
Best regards,
Bob

Re: Euclid R-62 dump truck
 

Thanks!
I used plastic for the wheels, both because it is easy to machine and it is light.
I don't have a lot of info on the truck, but there are enough pictures on the internet.
I plan on using hydraulics the dump function. I will make the cylinders myself. That will be a nice challenge!

Re: Euclid R-62 dump truck
 

I made good progress with the cab and the hood. The difficulty is finding the right measurements, but I think I am close. It starts looking like a big mean truck!

If you come to the watch fob show at Lakeside Sand and Gravel this year,
You could get some from Larry's 1:1 truck.

Re: Euclid R-62 dump truck
 

Look'in GOOD!

Re: Euclid R-62 dump truck
 

That's looking cool

Re: Euclid R-62 dump truck
 

I'm loving this build. It's looking great!

Re: Euclid R-62 dump truck
 

Looks great!! Keep up the nice work!!

Small update on the Euc.

I didn’t have much time lately for a variety of reasons, including a bad cold that kept on coming back.
But I managed to get the drive shafts done. I installed 2 temporary gear motors and that gave me the opportunity to test the truck and worked out some problems in the drive axles.

Really looking good can’t wait to see more

Re: Euclid R-62 dump truck
 

That dual drive setup is slick.

Re: Euclid R-62 dump truck
 

What is the plan for the operation of the dump box

Re: Euclid R-62 dump truck
 

I did some work on the Euc. I installed a Mabuchi 555 12V DC Motor, which seems to have sufficient power for this truck. And I built a temporary reduction box, so that I can drive it around and get a sense of the speeds. later I will build the final gearbox.

I tested the Euc in the dirt and took some videos:

Wow, that looks really good! I look forward to seeing it finished.

Re: Euclid R-62 dump truck
 

That truck looks GREAT!

Re: Euclid R-62 dump truck
 

I tried a simple mechanism for the tipping. It is basically a geared motor with a small winch pulling a lever, which does the tipping. This is the first try and I managed to lift it with a 11 lbs load. Not bad. Now I can optimize the design and I am considering putting the motor in a different spot. the space behind the cab is perfect for the battery.
