Liebherr LTM 1030-2

[texken]

Hi Mog, found the SQ tube, in All.
Also now know how to extend boon together like the real ones.
Made a wood model, used the Liebherr way on their home page.

OK found tires/wheels, found boom, working on boon mechanizes for raising boom.

Still meed to get two more tires/wheels (on order) for back, and motors to drive them.

I now know how to make the boom sections work, made it Out of wood to make sure. Will work like the real one.

Should have photos soon.

Now need to find a sound system, so when lifting something I get the sound, any input??
Just crane sound running, then speed up when raising boom, or lifting.

Later,
TEXKEN

Getting their, little by little
Receiver my last three tires today.
Also have outriggers getting their.
Have boom lifting cylinder almost, still need a good motor, any USA store and what size to get?

OK, found the 4" tires, love the pet store LOL LOL

Looks nice!
Check eBay for motors, there is usually a good choice.

Hey texken, you can try www.surpluscenter.com have them send a catalog, see if any of the 12dc stuff will work. http://www.surpluscenter.com/sort.as...&PAGELEN=10000 Not the entire collection, but give's you idea's. Later, Neil#2 aka doodlebug.

thank Kerst and doodlebug, will check.

Looking good Ken. Makes me want to find some time to work on my crane.

[texken]

All done so far.

Just added graded steps and bumper with block hook.

Still have to do some paint touch-up.

Okay, that works, too.
Do you use an FM radio?
For 2.4GHz, you will have to make sure that you can bind to two receivers at the same time (don't think this works) or switch models (computer transmitter) between chassis and crane (probably better).

EDIT:
Have to correct myself:
http://www.helireviews.com/fly-sky-f...h-transmitter/
Unless your 2.4 GHz transmitter behaves differently, this means that the transmitter will always send the same code and so different receivers (chassis and crane) will all listen to the same signals. You could still have signals 1-3 in the chassis and 4-7 (or so) in the crane. Hope this makes sense.

As to your design:

I do not see how you fix the gear to the chassis.

How is the bearing held in position?

I do not see how you deal with the axial loads.
The axial bearing should have a large diameter to create a stable platform.

What is the flange bearing in your drawing? The large plate?
I don't understand.

Cheers

Hi Jensr, OK the flange bearing has 2 bolts to bolt to chassis. (see drawing)
from under the chassis, with 3/4 sticking threw the crane deck which turns.
Gear will be screwed around bearing, on the chassis and motor with pinion gear to swing crane.

I think the bearing will work OK, with counter weight.

So what radio should I get. 6CH should work.

I saw the drawing - I don't understand it.
Are the parts labelled be(a)ring and the one labelled flange be(a)ring one and the same?
If so, this would theoretically work, but you need to be sure that the upper part interacts with the inner ring of the bearing and this will mean that your base for stability has a very small diameter. Not good.
Also, I do not know of any flange bearing with a flange that much larger than the bearing itself.

If however, these two parts are really two parts, I really don't know what we see here.

Which radio? Depends on what you want to control. 6 channels could be not enough if you want to control the outriggers in certain ways.
I'd recommend the Turnigy 9x v2, which is a 7.5 channel radio.
1 drive forward/reverse
2 steer left/right
3 boom angle
4 hook up/down
5 rotate left/right
6 outriggers out/in
7 outriggers down/up
half channel: driving light/working light

[texken]

Here is Bearing
top piece plate removed. Bottom plate bolted to chassis bottom to hold
Only the gray piece will be sticking thought so crane deck can be bolted to bearing.

[JensR]

Ah, cool. Yup, that should be much better than what I thought:
I have never seen one of these units with such a thin flange, only units with massive cast iron housing or tiny bearings where the outer ring has a flange/lip on it.

Pretty neat, will have to remember these

More pic when put together.

Those Flanged bearings will take up too much room. I forget what Tom used on his Marion shovel.
Look these over for some ideas.

More up date.
Received my (2) 1000 RPM motors from China today.
Also had to make my hubs, as no one had any for 4mm shaft,(that I could find).

So will see how they work as soon as I find some way to mount then to Truck.
Any input welcome. Did see some on line, look like a block with hole for motor.
