OK I will chime in here on DOING ANYTHING TO YOUR ROPS. Back in the old day before I found out about retirement I worked for a living. And yes I worked underground and surface, in the mining industry. Federal law prohibits any modification of any canapoes or ROPS, now I know this means nothing to you as a homeowner and there is no jurisdiction over us, at least not yet.
But I digress. I did an investigation on a fatality at a surface mine, ( I did to many investigations on accidents fatals), the operator had been cited for not having a ROPS on a rather old dozer, and the manufacturer had nothing that would fit. So with the intent of complying with the law he farmed a ROPS project out to a very reputable fabricating company.
And they built a very nice ROPS for his machine all bends were hydro formed, the welds, hell, I dont know who welded it but these were some of the best welds I have ever seen.
And when it was all said and done the citation was abated and all was fine.
UNTIL a bank let go and he rolled that dozer over 4 times, and a corner caved in on the ROPS killing the operator, DOA. (not a pretty sight trust me).
Long story short, his insurance company would not pay out to the man's family. WHY you ask? Because the company that built the ROPS, nor the operator had the ROPS tested and certified by a structural PE. That one little issue, cost a man his life a wife her husband and kids a father.
So what I am saying is any modification to your ROPS may cause it to fail,,,, YEAH YEAH YEAH I know well I dont have any hills it won't happen to me, I know what Im doing yada yada yada, all that is BS. Any time you attempt to mod a safety item you are putting yourself out there, and Im sure you dont want your family or the family of the next guy to have your machine suffer because you though ,,WHAT CAN GO WRONG ,, answer plenty!!!
