Im wondering how big of dozer cat has offered as lgp . Ive seen lots of D6 and a few D7 but nothing larger... Searching on computer i havent found many. But have told they build them. Anybody have experience with D8 or d9 set up as lgps?...... Hanco Sent from my iPhone using Tapatalk
Yair . . . All LGP's end up bogged to the azz. I can't imagine being able to do anything useful on plus thirty ton tractor on wide plates . . . unless it there were a herd of them around. Cheers.
Cat makes a D8R/T LGP machine. It's not really called LGP but its a D8 with a landfill config but its what most of the Alberta oilsands companies use in there tailings ponds
They do actually make a D8T that is branded as an LGP. That's what the oil sand tailings machines are built from, not the waste handing arrangement.
Only in Antarctica I think....
Does anybody know how wide the shoes are and what kind of changes are made to these machines to accommodate the wider tracks? ....Hanco Sent from my iPhone using Tapatalk
Actually Cat had a D8l lgp Freesen Inc. had a few and would push and pull their double barrels in the borrow pits ect. with them they had a rear scraper hook on the rear I have a Fiat 41b it has 36" tracks and 4" tall grousers
-Bigger wider pivot shaft -Wider e-bar -And final drives that have a wide housing moving them away from the machine (and longer axles) -Shoes are usually 38" (regular is 24")
There are a few D8 LGP's out and about, most of the ones I have seen are near Canada. http://www.machinerytrader.com/list...or-sale/list/?Manu=CATERPILLAR&Mdltxt=D8T+LGP
Yair . . . Thanks for link dblaneyfan Well don't that beat all. Anyone care to comment on the applications where you need LGP and ripper? I think those tractors would struggle with two tines in hard clay and would have thought track/plate life would be minimal running 38" plates over lumpy stuff. Cheers,
Muskeg over permafrost?
Yair . . . In Florida? (grins) Just being a smart azz lantraxco. Maybe alco or one of the other northern folks may comment. Bloody hell though they're big machines to encourage into marginal conditions, It's one thing to stuff around with a 65 Komatsu on pyramid plates . . . a D8t down to the floor plates is another thing again. They must be needed though or they wouldn't be out there. Cheers.
Oh that... mangrove roots, LOL!
Well this is what i wanna do with one... http://youtu.be/wnp7_z0qyEE Ive got a D8H doing it now but going to soon look to up grade ...Hanco Sent from my iPhone using Tapatalk
Yair . . . Gotcha Hanco. Sure looks like they would work on that application . . . I would imagine height of grousers would be important. This ground pressure vs drawbar pull equation is interesting I mentioned way back on another thread that a D9g on 24"'s will pull one on 27"'s backwards every time on normal soils . . . identical equipped machines. Cheers. *PS that's one of the best videos of pulling in drainage tile I have seen, thanks for the link.
Running that far and that fast in reverse seems a bit careless. Most guys around here push the runs into a header pipe that goes to a ditch so they can lay pipe both directions. Drain tile has gotten more popular in my neck of the woods. A couple of the local large farmers install it themselves with a pull-type plow and utilizing large tractors or dozers or both. The guys that do it commercially use dedicated machines with long U/C and very deep lugs. I couldn't find an exact machine but they resemble this one. https://www.youtube.com/watch?v=OgbF15PGoFI
It's an odd combination for sure, but my guess would be the LGP is needed for the soft spots that don't need ripping, and the ripper is needed for spots that are too hard to easily push. Not trying to be a smartass, but it would be for a machine to be more versatile, and not that both needed at the same time.
Yair . . . . Gotcha there alco , sounds logical to me . . . and I suppose if you were to have a machine set up as LGP there would be no reason you could not put it back on standard plates? I guess there would be a downside though. . . there's no free lunches. Cheers.
