Week TechVideo, 2011 #30 - A freaking tunneling excavator

It has been a long time since we didn't feature an Excavator...
The last week, Sariel published his latest work and imagine what it was?... Yes, one excavator! Although one of an unusual kind.

It is a model from a Liebherr R944C with a tunneling arm. The model features a blend of electrical and pneumatic functions, but it caught my attention because of their particular design and tilt movements on the excavator arm - accomplished by two small pneumatic cylinders.

Besides the milling head, the model could use any other sort of attachment like a bucket, a saw, a pneumatic hammer or something else you can imagine.

Overall this model uses 5 motorized functions (propulsion, slew, elevation of first arm section, drive the head function) and 4 pneumatic functions (elevation of the dozer blade, arm's second section tilt, elevation of arm's third section and angle control of arm's head).

As usual, better to read the original explanation from Paul at Sariel.pl and see the original set of photos.



Would I have the intention to continue updating my Excavators Hall of Fame, and this one would certainly deserve a full featuring section.
