Manitou loft ram split

[Deutzdx3]

Not mine, just seen on Twitter, pretty sure I’ve heard of manitou rams splitting before. Maybe on here. Not good though, they don’t make the rams but surely after a certain amount of time they should be checked irrelevant of brand.

Think @ACEngineering posted something similar in the past. Scary stuff.

Is it possible that it's not poor quality
ram?

No idea, I’ll put it across to them. You would think they would have a thicker wall on them. I’ve had a few repaired and see the wall thickness is frightening. 4mm-6mm [emoji15]

Ram split on ours too, it's not unheard of for Manitou I've been told. Ours split more in line with the end cap in a circle...

Its not so much the wall thickness thats the problem IMO, the cracks always start near where the pipe is welded in, which is right next to the end of the threads for the end cap, they undercut the tube when they finish the thread which weakens it! any i have repaired they dont undercut it and they never failed yet. Some i have had made with a thicker wall though but you cant always do that.

this is exactly what i was on about in above post, undercut inside the tube where they finish the thread.

Is it possible when the ram reached full travel the relief valve did not open
Quick enough causing pressure increase inside ram
Anything's possible

 

[barleybasher]

What was worse is that Manitou wouldn't contribute, machine was 4 and a bit years old but it seems pretty poor and destroyed my faith somewhat.

nah its just a bad design IMO, along with the fact they run at 270bar which is a shade under 4000psi that tends to find weak spots quite quickly

Why I got rid of ours and will never see another one on this farm again. Ours never split but I wasn’t going to wait for it to do so.

 

[startinghandle]

It is a bit odd that barley basher machine was over 4 years old when
ram failed

We replaced main lift ram on ours a couple years back. As it was turning into a sieve. Reckoned it was better replaced before that happened.
