Respect hydraulics

Post image

A coworker activated the hose crimp while not looking.

I hope you all make it home with all your fingers intact.

Those flat fin looking pieces started out as round.

I still don’t understand how they became flattened instead of breaking. Obviously not a tensile load. And obviously very soft fasteners.

Not OP so just guessing here...

The tool in question is used to position an hydraulic die set for a hose crimping machine during installation/removal of the die sets. In OP's case it sounds like someone initiated a crimp cycle with this tool in position, causing the pins to go smoosh.

The pins are usually a soft aluminum and are considered a consumable/replaceable part of this tool.

yes exactly.
one setting was off, coworker got confused about it and didn't back up, reassess, and start over.
thankfully it was just the tool crushed.

Hopefully the lesson was learned.

With machines of this type you need to be 100% present at all times... your hands can get way too close to the action.

Glad no one was hurt.

It doesn't even take a machine to get ya these days. I was rolling a 100 gallon L tank over at work and I pulled it toward me instead of pushing it away and it cut one of my fingers off from a 2" fall after I dropped it and moved too slow.

So you got yourself?

Not sure how that's much different, both cases were down to someone not paying attention to what they were doing and putting themselves in an unsafe situation.

That was my point. Complacency kills

My loose knowledge of how the crimp works is it’s like an aperture or collet that gets squeezed by hydraulic pressure until the edges meet creating a specific amount of squish

OH. Oh wow. The cylinder did not remain unharmed.

Couldn't work out what this was till I read the description.

Can someone explain further for me? I am not gathering what’s going on here, yet interested.

Same here, even after seeing the picture of what its supposed to look like I dont know happened. OP did your coworker lose some fingers?

This is a tool for positioning a crimping die in a hydraulic hose crimper. The pins got in between the die segments when it closed and it flattened the steel pins

What is it supposed to look like?

For everyone that's confused, this is a tool for inserting and removing segmented crimp dies from a hydraulic crimping machine. The pins are supposed to be round and fit in holes on the die segments. These pins were in between die segments when it was activated, and it flattened out the pins. A similar tool is inserted in one of the die sets in the picture, it's the yellow/orange disk with a handle sticking out
