Komatsu WA500-6 by Fumotec

[Arnd]

Hi everybody,

I would like to show you some pics of my Komatsu WA500-6 from Fumotec (http://fumotec.de/)

I will add some more picture from the set up.

Nice to see one of these new machines on the forum. What do you think of the WA500-6? I haven't heard very much about these wheel loaders, nor have we seen any real video footage of them operating. I'm surprised there aren't more builds or threads showing them off!

[Lil Giants]

It'd be great to see some video of it, if you have it? :cool:

[Arnd]

Hi,
at the moment I have only one video form the begining.
1. Test (http://www.youtube.com/watch?v=UdTps0VbqcI)

You can see the wheelloader is playing with 3 x 1.5L full water-bottles. No ballast at the back. No problem at all.

I will do some additional video, but the weather was sooo bad.

[Arnd]

I will start at the beginning: I ordered the Komatsu Nov. 2012 and four weeks later I received a well packed carton with all the parts in it.

The manual is give in .pdf-form and need to be printed.

The metall parts are made of cold rolled steel.

and at the most parts it is spot-welded.

All weldings are good connected even you can finde holes, which need to be filled later before painting.

Very nice machine and love the detail! Looks very sturdy and operates great. Thanks for sharing.

[louie r/c nut]

Nice piece of equipment looks like it is well made

[Espeefan]

Impressive lifting capacity! It seems to handle the water bottles, even without the hyrdaulics running at max flow.

[pigeonfarmboy]

Do want!!! This is my next purchase as soon as all the stars align!

[Arnd]

To work so easy you need a good hydraulic system.
The hydraulik pump is from Jung-Fluid. (http://www.jung-fluid.de/)
In industry the pump is running with 80 - 100 BAR.

http://foto.arcor-online.net/palb/alben/91/5328591/400_3839333863626464.jpg

Here in the Komatsu the system is tested up to 30 BAR. I run 18 - 20 BAR.

The hydraulic cylinders come ready mounted.

[pigeonfarmboy]

I forgot to ask. I've not seen a photo of the Fumotec unit next to another model for size reference. I know it's larger than the 966 WDC but still haven't seen a size relevance photo. If you have a Tamiya truck or something common like that, and get a minute to snap a photo, I'd love to see this.

[apfubar]

FYI sizes:
WA500
Länge: 705mm
Breite: 230mm
Höhe: 270mm

Wedico 966:
Length: app. (612mm) 24.09", Width: app. (211mm) 8.31", Height: app. (250mm)9.84"

So the WA500 looks about 10% larger than the 966. Not sure how much heavier, but I suspect it is a lot... The 966 is only about 8kg(17lb).

I am sure some one can dig up a picture or two...

Interesting.

[Arnd]

Weight : 13 kg

In original:
The WA500-6 is used in small minings.
It's not a machine to use on normal working ground.

[Arnd]

I just checked the bucket 248 mm outside.

[Arnd]

Hello,

As wanted I did a snapshot of the wheelloader and a truck.
It´s my 1:12 Faun L908SA 6x6 trialtruck.

http://foto.arcor-online.net/palb/alben/91/5328591/3534623366633666.jpg

http://foto.arcor-online.net/palb/alben/91/5328591/6564616132656364.jpg

So you see the Komatsu is a little bit bigger than a normal wheel loader which can be found at a building yard.

[pigeonfarmboy]

Thanks for the photo. That Trials truck looks like a good time!

[Kaf343]

Looks like an awesome model, nice build

[Arnd]

thanks, yes the FAUN is a good time.
Yesterday I started to create an area to run my gardentrial-competition on next sunday.
In the past I did this by hand, now I used my Komatsu.
I did some video, looking forward to upload to youtube.

[Arnd]

Hello everybody,

until the videos are available on youtube I would like to show you more details from inside the FUMOTEC.

Four brushless outrunners are doing the job of driving.

http://foto.arcor-online.net/palb/alben/91/5328591/400_3764343366333163.jpg

Every motor is controlled by a single robbe roxy. The four controller are connected via double y-cable at one chanel.

Each motor has around 100w power.

They find there place of working in the axles.

http://foto.arcor-online.net/palb/alben/91/5328591/400_3439626530613030.jpg

[Arnd]

The videos of my yesterday action are online.
They are a little bit long, but I didn´t want to cut, so this is real live without any palliation. (I found a new word in dictionary :) )

[pigeonfarmboy]

Looks like she needs some weight for traction. BBs in tires should do the trick. Looks like the tires don't have a problem slipping on the wheels. Are the wheels beadlocks or just glued?

[Espeefan]

The axles and brushless gear motors look powerful. Thanks for sharing the videos. Haven't seen anyone post videos of this loader working yet.

[Arnd]

Unfortunatly the tires are only glued.
If it would be fixed by beadlock it would be easier to add some weight in it.

Sorry about my German question: what do you mean with BB?

[pigeonfarmboy]

Ball Bearings or Lead Shot

[Kaf343]

If the tires are the same as the Stahl 922, which I believe they are, there solid tires. So weighting them won't be an option.

[Arnd]

The tires are from AFV-Modell (http://www.afv-model.com/html/start_en.html) => Goodyear 29,5R25 GP-4D (http://www.afv-model.com/4711shop/product_info.php?products_id=2837)

[Arnd]

Ball Bearings or Lead Shot

Understand.
I thought about this, disatvantage the noise you have while the wheels are truning.
Water plus antifrize is may be an option.

I will discuss at the weekend with friends. May be they can work out the back end weight from fully brass. At the moment it´s plastic filled with lead shot.

[Arnd]

some more pics from the set up.
to fix the fenders on both sides I placed a screw in the back of the front end.
with a smal water-level I could adjust it.
http://foto.arcor-online.net/palb/alben/91/5328591/400_6333326635316364.jpg

[Arnd]

Most holes are drilled, but the winding must be cutted.


http://foto.arcor-online.net/palb/alben/91/5328591/400_6534383861393363.jpg

I use a old drill chuck to hold the Thread cutter.

[Arnd]

The hydraulic parts have just enough space in the frontend.
http://foto.arcor-online.net/palb/alben/91/5328591/400_3066316263356638.jpg

[Arnd]

And the rear end is filled with battery, pump, oil tank and so on.

[pigeonfarmboy]

That interior is much more cramped than I had imagined. I was hoping it'd be more roomy to make maintenance easier.

[SmallHaul]

Very nice running machine, great build!

That Jung pump sure is quite, fast and smooth even running at 18 to 20 bar.. where could that pump be purchased separately? Are you running the pump at 12 volts/3s lipo?

Do you know how much electrical current the pump is drawing with your setup?

Thank You very much for sharing!

i don't see a belt driven pump on Premacon's web site? Maybe they don't carry that particular pump.

Ah I was thinking just pump:o you may have to talk to Frank maker of this machine

http://www.fumotec.de/englisch/index.php

[Arnd]

Hi, best thing to contact Frank directly.
The pump is on his side:
Jung Pumpe (http://www.fumotec-shop.de/hydraulik-komponenten/pumpen/pumpeneinheit-montiert-03-ccm-u.php) http://www.fumotec-shop.de/images/dscf0832_160.jpg

I run the Komatsu with 3S 5000mAh Lipo.

My Futaba RC-System is not able to mix to chanels as V.
It would be the best to run the pump smoothly just with small speed and only power up if pressure is needed.
But my FX18-1 can´t do so.

So I have to save my money to buy a RC-System which can do so.

Thank You very much. Interesting/good idea to allow the pump to run slowly when not needed, instead of shutting it off. i'll have to try that on the loader that i am currently working on.

It is disappointing how many radios don't have very many mixes available on them. i prefer 7 mixes.. 3 for hydraulics and 4 for sound. (6 sound mixes for an excavator)

[Arnd]

The power will have a peak starting the engine, so it´s better to run slowly.

[MoRockN]

Very nice machine! I need to learn how to use these mixes you guys are talking about. I have plenty of radios that can do it, I just can't :(

[Arnd]

Sorry for late reply I had holiday :)

Normaly if you mix to chanels the slave is doing the same as the master.
If you press forward (+) the slave will do the same (+). If you press backwards (-) the slave will do backwards (-)

In our situation the pump is running only in one direction (+).
It´s not allowed to the pumb to run backwards.

So if you press (+) the slave must do (+),
if you press (-) the slave must do (+).

So on a diagram you will get an "V".

Who to configure with your sender, did you read the manual?

[tracksntreadslou]

Good explanation Arnd ..I did mine with having a servo plugged into the slave channel instead of having the pump speed control so i could see the direction of travel at all times when mixing all the needed channels

[Arnd]

Hi everybody.
Yesterday I received the new cabin and interior.
The cabin is made from fiber glass, the interior is 3D printed.

sorry of the bad quality of the pics.

[Arnd]

some more pics of the interior and the cabin.
Interior is painted and the seat is covered with leather.

When ever I install a hydraulic system in any of my models I put in an accumulator, just a piece of tube with 1 closed end a piston & rod coming out the other end and a spring I play with different springs until I have the on Off pressure range I need, 2 micro switches, last one turns off pump when rod is out, when rod retracts to first one the pump starts all controlled by a small reed switch, controling the start stop action of the motor. The pump only runs when not at high pressure once there it stops. I get instant response when valve opens. This gives me lots of battery life

Thanks for the info. I was curious about this model.

Hi, just an update on the RC side.
I changed my old Futaba DX18, which wasn´t able to mix the hydraulic, to a
Spektrum DX10t. Nice toy. Now my digging time is longer with one batteryload.
