Yeah. I think I just don't understand the description very well.
From the video I saw originally it appeared consistent that a bullet had passed past trump & crowd a d struck a hydraulic line causing the rupture.
I don't know enough about hydraulic lines to know how resistant they would be to a bullet, and I don't know what rounds were fired either. Tough to have a valid opinion on this one.
.223 rounds have a lead core, yes. Every one of them I’ve ever shot or seen is fully jacketed. I’ve shot .223 through 1/4” steel plates at the range. Close range I confess. But a small round, jacketed, with a high velocity can penetrate steel. I guess it just depends on thickness etc etc.
CAT/JLG telehandlers use lock valves on the Butt end not the blind or rod end. The blind end does tie into the valve to pilot it open during operation.
That said, the only way the boom retracts is if the cylinder and not the hose fails. The original post is correct in that. What they overlooked is that the cylinder is fed by both retract and extend hoses on the butt end and then are hard plumbed to each side of the cylinder. Where these tube's weld on can get a pinhole from physical damage and fail in the manner seen in the video. That would be the only way it makes sense.
I am a current engineer staring at the Schematic on my screen.
It may have been punctured with a bullet. I use the machines and know they have redundant safety mechanisms to reduce the probability of death. I've never seen them spray like that when a hose breaks
The weight of the boom at that angle would load the circuit. When a hose breaks it is usually a gush of fluid. A pinhole to the cylinder/fitting makes the spray. I have seen defective cylinders do this exact thing in field tests. It is almost always in the tubing welds on the cylinder.
Edit: also the lock valve is built into the butt of the cylinder. So hose failures would only leak fluid trapped in them. It would have to be cylinder damage to both allow the boom to fall, and have pressure enough to spray.
I don't believe so because I do not believe even a .308 would penetrate a medium pressure cylinder of that size. The spray was more like a pinhole was caused from a strike on the tube or weld.
I don't know about this hydraulic system, but I do know that modern bullets are rarely made purely of lead, and armor piercing bullets are also a thing.
M193 .223 is thin copper jacket over lead bullet, and is going so fast that it will punch right through regular carbon steel (within a couple hundred yards anyway) The hoses are even more susceptible.
And that is presuming an AR-15 round. Only reports I have seen regarding the gun call it a "AR style rifle." That could include the more powerful AR-10.
Im a conspiracy theorist through & through but I find this hard to believe it was cordinated. This was in the direct line of fire & we all heard multiple shots fired. Im going with it was hit by a stray.
Really? How could you time that to happen just as the shots were fired? Unscrewing a valve would cause a leak whose severity would depend on the amount it was unscrewed, surely?
The pipe had to be struck by something, and it stopped as soon as the boom had dropped at which point there'd be longer be pressure in the hydraulics.
As for steel vs lead, has he never shot a dustbin?
On one of Salty Crackers recent livecasts, he showed that footage, and there also seemed to be a speaker/monitor being lowered by cable right near there too. Weird.
Is it merely an assumption that this is hydraulic fluid? When I first saw it, I thought they had turned on fire hoses to obstruct a potential shooter's line of sight. Additionally, if you observe closely, it appears to be spraying from two directions: the obvious one and another one directly opposite, 180 degrees across from the main spray. Notice that both produce an angled exit spray pattern, indicating that the fluid is being expelled from a small orifice at high pressure.
This tweet has been seriously undervalued. The OP has 40 years of experience in hydraulics. Look how close to the stage this “leak” (more like a small explosion of water) occurred.
Occam's Razor theory says that a bullet hole might be more likely.
A shit ton more likely
Very succinctly put.
That was my First thought....
I was under the impression that a stray bullet had hit the hydraulic line?
That was my take last night.
This, is like directly in the line of shooting
it doesn't look like hydraulic fluid... looks like water. Hydraulic fluid is usually red.
The hydraulic fluid in every heavy machinery I've used is typically clear with a slight yellowish tint
OK. It's been a long time for me. back in the day is was dark pink when new turning dark red as it got old.

Looks just like these burst lines.
Also, hydraulic line failures are freaking scary!
That was my assumption also.
Edit: X OP mentioned "Leak is opposite the shooter cylinder is steel, bullet is lead." - so maybe not possible?
Bullets of most any caliber and construction will easily penetrate a hydraulic line at that distance.

Me neither, and since nobody has asked the tweeter about it maybe being a line punctured, I have posed that question in response to his tweet.
You fail to consider physics.

No argument there. I only have field use experience regarding this type of equipment
Would that verify the type of round as well, which would be .22 or .223/5.56? Any other caliber would make a larger hole than that.
I don't believe so because I do not believe even a .308 would penetrate a medium pressure cylinder of that size. The spray was more like a pinhole was caused from a strike on the tube or weld.

That's the first I've heard of that happening. Thanks.
A first for me, too gobby,...
This verifies the report I heard Saturday about water shooting from the right.
good find!

If you haven't seen it there is a video of the aftermath where this thing blows off. I can't remember where I saw the video, maybe someone has a link.
Here is a video of it. The one I saw earlier gave the impression the timing was much later.

New info for me!
