Here is an old video i shot of a pretty neat komatsu 1250 video, i figured i'd share with you all. That thing sure has some reach doesnt it? Enjoy. http://youtu.be/reRu9jTSh70
I guess I don't understand what I am watching . I understand the slurry wall , but I don't see much digging going on .
In that line of work you cant just dig full buckets all the time, theres alot of scratching going on depending on how the material is. Usually there is a second crane behind the excavator.
