Hydraulics Pressure vs. Hand

Enough said.

Had a boss once, brilliant in some ways but little common sense - he had a small Kubota, maybe 25 horse. Tractor was turned OFF, loader raised. He saw a small pinhole leak in one of the loader hoses, and put his THUMB over it??!? Nearly lost the thumb, still having problems with it over a year later.

My point - even without obvious power applied, STORED energy can hurt/kill you just as easy... Steve

Hmm....well I wouldn't have thought the stored energy behind a leak would be sufficient to penetrate skin and cause problems...learn something new every day....agreed, remove pressure always from hydraulics when engine is not running.

texasjohn, if you re-read my post the loader was RAISED at the time - so the weight of the loader pressing against the lift cylinders was the "stored energy" that supplied the hydraulic pressure -

I've been in industrial maintenance for the past 33 years, and we got safety training on everything you could possibly think of and a few things you would NOT normally think of - stored energy can come in the form of electricity (charged capacitors for example) weight supported by a latch that could fail, liquid or gas under pressure in a pipe, etc. -

I brought this up because I'm sure a LOT of our members did NOT have this sort of mandatory training and may not think of something as dangerous til it's too late. Thinking things through "just one more time" may save a body part or a life. 'Nuff said... Steve

I knew to be careful, but that sure drives it home.

I had a line rupture on a backhoe years ago that shot out into my burn pile, didn't even see it until it ignited; scary stuff.

Why was the loader left raised???

Murphy, did you miss this? "little common sense' in my first post? This guy was actually an MIT grad, but so little common sense that nobody wanted to work with or near him, no joke. He could find so many ways to screw up by not thinking things through, and then so many ways to explain what happened (after it was too late). Downright scary... Steve
