I’d love a go on this machine. We run Liebherr dozers & recently saw quite a few of these waiting delivery from the Liebherr factory in Austria. While we were there, we were treated to a go on the new 736 Generation 8 machine, which is fantastic & an improved version of the gen 6 version. Would love to see a video on the gen 8 if you can find one working in the UK.
I’d like to try this machine. Being hydrostatic would offer many benefits. Being able to be high idle constantly would offer stronger hydraulics, turning, and control overall. A downfall would be increased fuel consumption vs conventional trans dozer like a d10.
ippielb Liebherr actually say that this dozer is 20 percent more fuel efficient than rivals. They never mentioned what rivals, but have to mean Cat and Komatsu.
@@AwesomeEarthmovers Is that when doing a full load push? Or Estimated over the life of the machine? Advantage to a conventional trans dozer would be able to bump up a gear, but push the decelerator down, when full rpm isn't needed. While the hydrostatic would be high idle. I'd be curious to see long term comparisons.
Been running hydrostatic dozers for years. Transmissions are nearly bulletproof. Never need to decel unless you want to stop or do some delicate work. Seems hard to believe, but they push hard.
Although it seems counterintuitive at first, constant high idle is actually beneficial when it comes to fuel economy. Every time you decel, you then have to accelerate that whole rotating mass back up to speed again which is murder on fuel. I ran a 724 Liebherr dozer for a few months last year and while I didn't have another machine to compare it directly against it seemed like it was quite good on fuel. Although it took some getting used to on my part (always wanting to stab at that decel pedal, I'm an old Cat guy and it's just reflex) I got to like it and I thought that the way the machine was designed had some merit. It was a 165hp roughly 40,000lb weight class machine and they used a big, long stroke 4 cylinder running at what I thought of as a moderate 1800 rpm. It was a nice machine to operate and while they have a way to go before they catch up with Cat as far as dozers go it seems like they're going in the right direction.
I got on older lieber excavator as i always heard how smooth controls were. No lie there, I had to get use to it being so smooth and touch sensitive to behavior of components.
diggermitch1 It’s the same size as a Cat D10. I don’t really know what problems they encountered with the machine. It is a prototype so I’m sure there were certainly failures with drive systems and components that were rectified before the production machine was launched in 2016
Great drone flying, very smooth.

I still believe cat has more push power

Great work. Like!👍
BEAST mode!
I saw this machine at Vegas Minexpo a few years back. It was impressive.
Land Surveyor There’s a video on this channel of that dozer being moved out of Minexpo 2016
Great bulldozer, but isn't it more efficient to use a scraper for removing long stretches of soil like this?

Uh
What gear is being used to push this vid
Love this machine
Watch .. for now!
It,s a liebherrr pr 776 with v 12 liebherr engine and linde pupms
in what size it to a cat a d-9 or a d-10 and how many hours do they have on it and have they had any problems with the hydrostatic drive yet

Happy new year
Dankie oom Hans Liebherr
Bet its got a doosy of an oil cooler
Not bad, but I think I’d rather have the big Cats
Liebherr?
How the hydrostatic drive system works?
Your favorite search engine is just a few fingertips away.
Engine drives hydraulic pumps, every thing is run by individual hydraulic motors, even the cooling fans.
good
Great!
Не вскрыша,а мечта.
