Liebherr R984C excavator

[CAT992G]

Liebherr R984C working on a highway project in germany.
It has a 11,7 cubic yard bucket and 685 hp, weight is around 120 metric tons (132 short tons)

I have some more pics from 984´s in germany, if they are interesting for you...

yeah what he said

 

[cat 385]

more please

That's a big machine to be working on highway construction - must be just under 100 tons.
They use 984's for coal stripping operations here

seems like it would need a longer stick to be of any use in the pipeline business...nice looking machine tho

Off topic, but, Are those windmills on the ridge in the distance?

NO they are windturbines which produce electricity LOL guys here get all riled up when you call their turbines windmills its pretty funny to see them get so bent out of shape.

When do we get som more pics?

 

[CAT992G]

Some pics of the same machine. Its only used for mass excavation, so it has a short boom/stick for high digging forces and fast cycle times.

R954 size and up the boom cylinders are installed with the rams down to help keep the dust off.

You can also get them with factory "rock guards" which provide additional protection:

The rams are mounted that way because it is easier to run the hydraulic lines to them, rather than bringing another set of lines out from undrneath the machine.

Mismatched equipment

That job need' s more trucks, and larger ones , or a smaller excavator.

Mismatched equipment.

Actually now that I think about it the rams would have a little more lifting power mounted this way as well as there would be a greater surface area for the hydraulic pressure to push on. With the cylinders mounted the other way when you are lifting the ram takes up part of your "pushing" area.

Have a bit more of a think about that statement.

We discussed this a month or so ago and I speculated that it was done that way to aid in the repacking of the cylinders which turned out to be the case as reinforced by somebody that knew the answer.I have forgotten who it was.Ron G
