1:14 Liebherr LR 634 Carson - Leimbach

[kamyoncu]

@ Espeefan ,

I bought it from ttm modellbau (I live in Turkey and a couple companies send it here)

I absolutely believe there is enough room in the chassis for everything. I am going to arrange electronic and battery and I am going to add their pictures.

I aggre to you about bucket problem, and I tried to fix it. However It is not easy to fix, There is a need of new joint or new hydrolic boom unfortunately. I belive that it will not hurt me when I will play and I ignored it

@ptebbe

Tracks are plastic or pvc something. I did not painted tracks they printed before. However it is a kind of undercoat paint like all chasis parts. I painted chasis with the same liebherr gray and I used polisher but I was too lazy to paint tracks

@alococat

Carson is 11 kg now without addition of weight. It really conufuse me

I know 3/4 rulez and it was 3/4. When I stop pump I can see it, but it works very fast and it procude foam Therefore I changed my battery preferance. At first I thought to use 5s lifepo 16.5 volts because of hydrolic I am going to use 4s lifepo 13.2 volts.

Kamyoncu,

Sorry if Im confusing your mind about weight, I need to check one more time this information I have read in a french forum, cant find the thread at the moment.

The weight difference might come from the difference between hydraulics and electrics models.

About the foam of oil, I do remember on my LR632 and my A25C models I had this same issue when I was low on oil.

[Espeefan]

Thanks for the information, Kamyoncu! How high can the bucket lift? Do you think it would be enough to load a dump truck or trailer, without the need for a ramp or elevated piece of ground?

Morning espeefan,

In this video you can see this track loader has enough height to load dumpers.

This vid shows the lift height a little better.

@ alokocat whenever you see the topic please let me know.

@ espeefan I will add pictures with my mercedes 8x8 osswald truck on the my woking table ,so you can see real ability of loader.

Kamyoncu,

My memory is going from bad to worse I guess

This thread :
http://camions-rc.fr/forum/viewtopic...14829&start=30

The LR634 weight 7.5kg without electric motors and cylinders, and weight 10-11 kg when finished...It's with the electric version, I guess the hydraulic should be heavier.

Please more videos by the way

[rcguyfarms]

watching ur videos has inspired me go hydro on my carson track loader.

[Espeefan]

Kamyoncu, what voltage are you running your pump at? I saw some specs on the hydraulic kit for the Carson loader and noticed it assumed a 7.4 volt battery pack. Your pump does make a lot of foam, when it is running at max speed, but maybe some of that has to do with a higher voltage? I do agree with others. I think the oil level could be a little higher.

[kamyoncu]

thank you rcguyfarms

thank you alokocat I will take new videos soon.

Nathan, Both servonaut and leimbach electronic systems allows maximum 4s lipo (14.6 volt). I used 12 volt in the videos. In the future I will use 4s lifepo (13.2 volt). Before taking new videos I will add little more oil into tank to see results

[Lil Giants]

That brushless motor Leimbach offers with their pump runs about 30% faster then the brushed motor. To my understanding , the brushed motor was approx 6000rpm on 12v & this this brushless is about 9000rpm.

4s lipo is 16.8v on a full charge & is down to around 14v when it needs to be recharged! I understand lifepo is lower overall voltage, but how much exactly I don't know.

Whatever voltage you choose to run, I'd recommend you back the voltage down for the pump to 11 -12v by adjusting the EPA, that'll give you plenty of volume for quick response. Run that pump too fast & it could self implode!

Better yet, does your radio allow for channel mixing? Mix the valves with your pump so the pump only turns on when you open a valve; prolongs run time per batt charge, make your oil quality last longer between changes & extend the life of your pump.

[kamyoncu]

Thank you lil giants. I use FC 16 and I know that it allow mixing. I am going to try it.

About self imploding, nozzle and nipples seem ok when it wokring and when I puss with my hands, however hydrolic pump scares me.

[rc13]

Thanks for the details. I am to purchase one soon. Is there enough room in there for more hydraulic valves?
Thank you,

[kamyoncu]

@ Rc13 unfortunately there is no room for extra valves.

Here is outisde test videos. I used 12 volt battery and It satisfied me.

It passed so much time but it is time to make interrior of the loader.

Firstly I cut the rear gravity. Because my batery is a lifepo and it is massive.

Than I made some small details under the cab.

Than I settle leds on the cab.

[kamyoncu]

I am keep going

[Espeefan]

Very nice work! How large is your battery? It looks huge, and ready for a couple hours of non-stop operation.

[kamyoncu]

It is a 4s lifepo actually smaller one ( there is only 2 version at HK) . The most important benefit of this batery is 13.2 volt and all 12 volt stuff support it. I can drive loader non stop 3*4 hours. (after that much work naturally hydrolic pump burning) .

With the same battery I can drive my truck 5*6 hour nonstop or 3-4 hour wedico cat 345 D . As short I have 4 from this batery and I can drive all my machines nonstop from noon to evening

[Espeefan]

Wow! What is the battery's capacity? Mili-amp hours? 10,000?
