Now that is a stack of logs!

Big lowbed in Holberg

Huge lowbed being rebuild - 120 ton?

Seeing the hydraulic connections for the ramps I assume, where was the pump when being hauled around by a log truck? On the trailer itself? I never thought of it until I saw those bright new hydraulic connectors.

Most of the logging trucks used for lowbedding were Preloaders with 5th wheels and were set up with hydraulic rams to change logging trailers , so there were PTO hydralic pumps built into the drivertrain .

Thanks, learned something new.

Thanks, learned something new.

There was a hydraulic ram under the 5th wheel to lift the front bunk up to put the preload legs down under the front bunk . Then lower the load onto the preload legs , unhook the 5th wheel and drive out from under load . Then reverse the operation to hook up to an empty trailer . Some trailers were loaded onto the truck using a winch (run by hydraulics) or hydraulic rams . One thing we had to be sure to do was lower the 5th wheel down to bottom , before loading an empty trailer or it could cause significant damage .

I've got a question for you all that have driven these big fat trucks. What kind of average speed did you run out hauling logs on those roads?
I got thinking about it after they got a couple new Western Star 6900XD dump trucks at the mine I work at. They have Cummins X15 525/1850 and the older ones have C15 Cat's with Allison auto's and 110,000 rears. I can't remember the gearing but they can run 60 KPH and not very much more and we load up to 60 metric Tonnes on them, so they are grossing 100 tonne.
But on all our hills they drop right to first gear and can basically only crawl.

Not sure what are hills are, but the dash displays in the Cat wiggle wagons show 14 to 15%.

Its been awhile , but some HDX Hayes and P16 Pacific's in the area I worked in had 13 to 1 gear ratio's in rear differentials or 15 to 1 gear ratio's . It seems that it was the 15 to i that was used in the trucks I drove . We never had speedometers that worked but I recall seeing on a brass plate maximum speed 42 MPH . I can't remember what gears we used pulling adverse grades with 6x4 standard trans fully loaded , but 2 and 2 would be a safe gear with a natural V12 Detroit . With an Alison power shift trans 1st converter on a hard pull . If the grade wasn't to steep the trans might shift into 1st lock up .
I recall a time I was filling in driving logging truck in a camp out of Gold River , there were two HDX Hayes with V12 Detroit's with Alison trans . The truck the steady driver was on dropped a rear differential . There was a spare rear differential in camp , so we spent half the night changing it . The next morning the driver took the truck out for a load , little did we know the replacement differential was a different ratio than the one we took out . By the time truck got back off the hill loaded , both differentials were B/O .

Thanks for that Camptramp. Good info. Sounds like they all run about the same.

Over the years he worked his way up the rigging jobs to Landing Bucking , then took on a position of Assistant Fire Warden eventually becoming the Camp Fire Warden . These pictures are of Pete giving a Logging Crew a Spring Fire training course .
