Yair . . . I thought this was interesting http://www.youtube.com/watch?v=E_HFR9L42Gk Cheers.
Komrade Engineer didn't spend much time on looks did he? The tracks seem to have come off of a tank, that's pretty interesting. In one scene, it looked like he was doing 15 mph. I'd like to see an honest evaluation after doing 10,000 hours.
Notice the mention of it's cold-weather capabilities?
Looks alot neater under the cab than say a new D7E,
Yair . . . d9gdon I think you nailed it in one. The thing is though these blokes have been building machines for a long time, apparently their first electric drive came out in 1961 . . . you would think they'd be getting the ducks in a row by now. I wonder about those tracks. They stick with that tank style design sometimes even running double sprockets which are always higher than the carrier rollers. You would think there has to be a reason. Cheers.
One nice thing about that undercarriage is no load bearing on the finals and more sprocket contact, and it being so long it should be pretty stable. Strange looking thing though. lol Some of the cab options look like you could haul the whole crew around in it.
What is amazing to me is that there is no black smoke pouring out the stack. Almost seems wrong for a Russian machine.
Probably hired Australian engineers, make it look like it can do something, but don't give it any nuts. You might be mistaken for an American if you do.
Valve covers on the engine look just like the V12 Detroit. Long wide tracks won't allow that machine to push anything but the loose material in the video. They stood the machine on the blade and it still wouldn't penetrate that pasture land. Decently done video ad though.
Yair . . . 95zIV . Care to elaborate on that first quote? . . . I'm lacking comprehension. (grins) Cheers.
Looks like they had enough time to reverse engineer the Cat D-7E.
The tracks, the general design and performance of a lot of their dozers leads me to think all you need to do is add a turret to turn them into tanks. You think maybe?
That's interesting. Looks like on there mid range dozers they still use rails ,then on the bigger models they use the "Tank" style track. http://chtz-uraltrac.com/catalog/categories/3.php
Nice find on that link, 25!!! OCR
Looks like the d7e is not so revolutionary !
Found this, seems they don't have much down force due to not much weight! https://www.youtube.com/watch?v=o3ayDUNJNE4 Not too impressive until it almost got a bite. If a cheap machine to buy could become a play til drops and buy more type. I don't get the 'Tank rails' either, must be a method to drop costs using existing materials.
Looks to me that the 7 is a size or two bigger tractor and the russian tractor a lgp? He would have quite abit less traction compared to 7? We have had lots of pushing contests with Cat 7g's and 8ks and in almost every case whoever has his blade lower will win. The only true way is to hook a cable to the hitches and have a tug o war!
Put one blade in "float", then the dozer with the weight and power advantage wins.
:beatsmeWhat would prevent the dozer on float from being pushed up?
I think then you won't lift one machine and loose weight on tracks, he who lifts gains weight of other tractor
