Maybe it is a tire flattener because I picked it up out of the road and put it on a stump.

Looks like a tooth from a compactor that some trapper made into a drag.

The pin holds the bunk in place while the truck is being loaded. The pin keeps the bunk from pivoting until the loader gets all the bunk logs on and then the driver usually pulls the pin out and it rides in a holder alongside the sub-frame of the bunk. There's usually one for the truck bunk and one for the trailer bunk. They're tapered so that even if the bunks slops a little to one side or the other the pin still comes out easy. If you leave the landing with your bunk pins in place the bunk won't pivot and the truck won't turn.
You don't see trippable stakes much anymore.

Chairin'em for the sound
You should post more!
Explain trippable stakes please.
For the rest, that's why log trucks can negotiate a smaller radius curve than a regular truck. The bunks can turn a bit. We can have scary roads and still get logs down them.

oh I see, they keep the your bunk pinned to the fifth wheel while you load. or at least I think I have the jist of it.
those type trailers havn't been used here since the piling boom in the 50s n 60s. on our pole trailers the bunk is part on the trailer but built right over the fifth wheel pin. the trailer pole is extendable from 30' to 75' tho we never go past 50' any more.
slowp, trip stakes trip and fold down so the logs can roll off. very dangerous and they all welded up now days. my father's cousin was killed that way. any trailer we get I weld right away. I suppose they came up with that for the many small mills that sprung up and didn't have but small loaders or tractors to push the load off. not the case any more so welded they get.
by the way, those piling rigs where no more than a fifth wheel bunk and a bunk on a tandem, the peeled trees where the frame, up to 100' long. empty they put the tandem on the tractor to go back to the woods.
they paid a dollar a running foot for them piling in the 60s........wish I could get that now. then again I don't want to peel pine trees with a spade lol.

Some stakes are hinged at the bottom where they fit onto the bunk. In the old days you could "trip" your stakes and roll logs on or off if there wasn't any other way to move them. There were usually safety devices, mechanical lockers or cables, to keep the stakes from releasing accidentally. They didn't always work.
If you were hauling big logs you'd lay a little brow log alongside the truck and trailer tires and release the stakes. The stakes would fall and rest on the brow log and would then form sort of a ramp to help in pushing or pulling the log up onto the truck.
I've never actually seen this happen but my Dad and my uncle told me about it.

my uncle brought this old trailer here last summer hopeing I would buy it.
yer supposed to release the trip on the safe side but many times they just sit there and guys would walk around to see why it didn't trip........not a good idea.

yep back in the mill pond days you could just pull up hit the trips and presto you was unloaded, the danger being that guys would have to pull their wrappers off before unloading, and occasionally there would be a log on top that shifted and would roll off the wrong way. That and the dummy's that would wander around to the wrong side to give it a poke.
The other problem with trip stakes is that cable that holds the whole works together can get worn quick like, if the driver is an ass or lazy it can pop while choogling down the road, I'm sure you can imagine the pandemonium caused by this.
The only trucks I've seen still running trip stakes are the ones in parades or at the log shows usually behind some 1950-60 era truck with more chrome and a fancier paint job then they ever had in working life. Kinda like the old farts driving them... except their chrome is in knees and hips...

Good read, learned something this morning.

38 seconds in. Dumping into water. I see in this one they are lifting the load lots of times they'd just roll it off. I know a few drivers back in the day that, if they had a POS stacker op that wouldn't unload them at the end of the day even though it was still open but a few mins to go till close, would just trip the stakes and leave it in a pile in the yard. Usually only happen a few times and the stacker guy would get a chewing out or the driver would....
