Jesus!

Does the slew have bearings in it?

 

Did the bolts shear or just all come undone?

Just came undone, we found 8 of the 12, the rest must have been lost over time.

The slew seems undamaged.

Tbf, no one could have foreseen this.

I bet the next person it happens to could have now!
I’d have thought critical bolts should be checked with a torque wrench at PDI?
If there is nothing in the operator’s manual to suggest re-torquing at a set interval (which you subsequently haven’t done) then it looks like a manufacturing fault to me.
Did someone forget to use thread lock during assembly possibly?

It’s not a new machine, far from it.

99% of slews get regular grease and work without any issues for years.

But yes, thread lock during assembly would have been better.

It doesn’t seem to be a super robust design to be honest, bolts too short, would have better if they’d come through the slew to nuts accessible and visible for the operator/owner.

Ah, ok. I’ve misunderstood - for some reason I thought it was a new machine. Once refitted will they be visible in operation? Might be an idea to put a line of paint across them if so to make it easy to keep an eye on.

Not doable, they’re only accessible under the machine, after taking off a protective plate, not visible only ‘feelable’
