Track loader

[GuiliuG]

Not a lot of things to say about this one :

This was the last MOC I built for fana'briques exhibition. Most of my parts was taken in others creations, which limits me during this building.

Two M motors are used for arm movements. One of them is directly attached to the linear actuor. Indeed, I hadn't no more 12t sb gear and cv-joint.

Xl motors are used for propulsion ( one Xl for each track), both with a 12/20 reduction. As you can see on the above picture, there are two mini turn-table. These one are usefull to increase rigidity in the balance system. It works thanks to the track "flexibility" because rear gypsies are fixed ( meaning there are two fixed points).

In action :

Most difficulties during building came from exterior aspect itself where I needed to use some plats ( a technic that I'm not used to build with)

Finally, after some trials, it turned quite well

Here, some pictures during building process :

And finnaly, the video. Sorry, I dind't take a video with both loader and skip truck :/

Next, I will present my hydrema dump truck, recently finished. I'm open to any comments as usual( begin to be boring to say always that :p)

There is a lot of power in that Lego Track Loader! It looks and operates much like the real thing:

Looks very beautiful as usual.

TS(Thread starter), First of all I will say that it seems to be a quit nice moc. With the right balance of features and mechinal power, and best of all it uses my favorit drivesystem(tracks) despit they sometimes can cause quit a bit of troubles .

Oh and just for the record my old 4x4 xl driven tracked tank has been dismantled, and I didn't do extra photos or a 3d cad file of it(manily because for the last few months the amd ati catalyst drive has been quit buggy, and running diablo 3 has been more important). And doing the dismantleing of it I could help but play for a few minutes so i built a tracked 2 * xl drive thing, first with differentials and wheels, then I changed my mind and kept all of it, but replaced the differentials with knobs wheels and allmost at once I noticed a lot more vibrations with the rest unchanged. Has any of you experinced something similiar?

Thanks.Alasdair, I will take some pictures of the balanced system, so you can understand how it works !

And GuiliuG, I will propose that we should forget our old disagreement, but another thing I like about it is that got lego-ish feel to. Maybe a small bit overstyled maybe not. And that is I from the start of will admit I am not good a finding.
