Cribbing for larger trucks

[dzzz]

I just got an email that factory mog tools aren't sold through parts dealer in North America.
I've read that a good way for firefighter to move cribbing is with a cloth firewood tote. Don't really have the need for easy rushed handling in a camper.

Hi Don

I'm not sure if the link below is your posting? But some pics of my 10000kg Mog jack lifting my 9.5ton U1700 with 395s. Floor to axle tube is about the same as the jack fully extended, so broadly speaking the thickness of the bearer on flat firm ground is how much free space you get under the tyre at this size. Extends about 16" to 27". Which is why I was wondering about the need for so much timber

Yeah, that's me. The timber is because I can't find a jack that goes from 16-27". Either bottle jacks are short or go from 24-43"
Raising a short bottle jack to start at 16" takes about 10 pieces of 4" cribbing on hard flat ground.

The truck's about 12 tons, so I need at least a 8 ton jack. I don't believe jacking from the frame is done on a truck this size and height. It's either the axle or suspension piece.
I do have the longer hi-lift jack, but don't intend to use it on this truck. This is the longest lift regular bottle jack I could find:

And a long ram jack that might work for higher/longer lifts:

The long ram is somewhat too long at 24" closed
A 20" closed, 16" lift would be about ideal.

What about a 10-ton port-a-power? My deuce and a half weighs about 18,000lbs and I've got a bottle-jack that I usually use, but a hi-lift will get the front-end off the ground in a pinch (rear is tandem-axle).

What about a 10-ton port-a-power? .....

The stoke isn't very long, and it would probably require an axle stand.
Anyone with a larger truck carry an axle stand when traveling?

I was thinking that you'd use something like that in combination with some type of straps between the axle and the chassis like I'd previously suggested. Was just thinking it might be a viable alternative to a hi-lift if you're concerned about the lifting capacity.
