We would never be allowed to sit in water like that to mine the gravel out here in BC, Fisheries would send us to jail!

At the bottom of the ditch we have for sewer it's opened up large enough for a 330C L to sit down there and crane pipe in, which is why im guessing they dont make us pull a box. When the main hoe digs it he opened it up at the very bottom 5ft for a 36" pipe, but thats only the last 2 meters, it then steps up to 10ft wide. At the bottom of that hole the 330 is behind him craning pipe in, sanding and then he backfills 18" of dirt on top of the pipe and pads himself out for the next cut.
Backfill is carried out with my 973C Track Loader for the first 5ft above pipe, I get the first 2-3ft of dirt by cutting the walls out and spreading it, but after that we cut holes in the spoil pile and push dirt down in. I chase the pipe crew with the track loader and have a Dynapac Sheepsfoot 15ton packer with me. After me to fill the rest of the cut we normally use 2 dozers 1 to push dirt down and another to spread it around. For the spreading around we use a D8N since its a nice "trim" dozer as everyone calls it. For pushing down they bring out the real iron. We used a D10N and for awhile a D10R. He pushes a mountain of dirt down in the hole and if the 8 gets too far behind... you make a ramp and fire the D10 down in there and spread with it.

Yeah... it's interesting coming to work and looking at 2 385's, a D10N, D9N, 2 973C's, a couple 330's, a 375L, 4 or 5 packers, 2 or 3 966 loaders, and for a hoe pack.. a Link Belt 210LX or a 710G John Deere backhoe.

Thanks for the great pics.
Do you have any close ups of the axle groups on the lowboy? it looks a little different than the 16 wheel groups we have here in CA like the one in ROP's post with the 245 on board.
I agree with the pre trenching with a big hoe, instead of scrapers. One 385 can swing around 12,000 cy per shift in those conditions. It would take several scrapers and support equip to match that.

That run we did this year was about 4 kilometers. We did another 48" plastic main that was around 2km but also around 12m deep. And then we did a 10" Sanitary sewer that was 14m deep but was only about 1.2km long. I was talking to a couple of the guys today and we just got the ok to start another deep storm sewer in another month or so. Their going to be moving a hoe into the jobsite to start pre trenching within another week or two. And I got some pics of a 385 sitting on the side of the road today. I'll load em up later on tonight.

nice pics! i like the tinted windows!
Looks like he raised the cab to avoid getting wet on his feet.
i noticed on another pic of a trac hoe the cab was raised a long way up, i thought it was a special hoe, ive never seen one do that, do all 385s do that?
