Yeah, never get under any raised Hydraulic system.
They have a piece of metal like channel iron to put along side the ram as a safety.
Even a raised dump body on a truck has a leg you drop down for safety.
Yet we trust a cheap Chicom Engine Hoist Ram with a 1000lb engine hanging on it while installing it.
I was running a JD 544 loader pushing sand up in a pile as the trucks were bringing it in getting ready for winter. Go up the pile, dump Bucket, shake it and the guts of the Ram shot out and ...Bam Bucket dropped. This Loader had just one large Ram for lift and curl. It did have a lot of hours on it.
Blew a hose on the 4 in one bucket, on the Ford A62 and the Dresser 510.
Was hauling butt back to the yard after running a JD 672A Grader all day. The main hyd Hose, (3/4 inch) where the metal coupler is crimped on, blew off. Was slowly loosing all hydraulics, and ran it down a high dirt berm and the blade dug in and stopped me. There was 40 some gallons of Hyd oil trail down the road behind me.
Had a guy running a Flail mower on the 3 pt hitch. Something got tangled up in it. Shut it down, but failed to drop the safety leg, and it came down on him as he got under it and killed him.
My JD 950, knew the Loader Rams were tired. It wouldn`t lift a 7.3 engine out of my PU, but could curl the bucket. bring to the shop, get off to get the Dolly out of the shop, and hear this Bang...Bang, and the lift Rams were bleeding off.
So downed it and got all 4 rebuilt.
As I use to kid around at work, "Safety first, unless it get`s in the way of production".
But yet, we still take our chances.
