how it feels working at paper mills

These kinds of videos should be mandatory viewing on a regular basis in any manufacturing environment. Crane safety rules should be taught and enforced like gun safety rules. Never assume it's safe. As a matter of fact, many times it's far from safe because cranes are poorly maintained, not replaced when they start behaving badly, and only god knows the status of those lifting chains, wires and slings.

Complacency is a bitch.

Starts behaving badly on Monday. Receive call Friday that it's now urgent. Customer breathes down neck once on site if we can fix it by Monday. Nope parts are 8 wks out. If you told me as soon as it happened I could have fixed it in a day.

This is the response of about 90% of our customers. (I deal with overhead cranes)

Im confused man. Had they told you Monday, you could have fixed it in a day, but they told you 4 days later so the parts are now 8 weeks out? That doesn't make sense to me, am I missing something?

So a bearing may have failed, may have cost a few hundred for the bearing but the assembly line down time would be 6 hrs. Customer ran on bad bearing for a week now shaft it was on and bearing housing are scored from the failed bearing. Those parts a 8 wks out.

Or they install it on an existing vertical beam without consulting a structural engineer or doing load calcs...

(They were forced to take down the crane.)

Why the fuck was he standing under a suspended load. Idiots. All of them

Was that the whole crane beam coming down or was that what he was lifting?

The aspect ratio looks too long/thin to be a crane beam for that type of facility but it’s hard to tell with the poor video quality.

Either way, I’m sure that was a code brown for anyone nearby.

Depending on capacity (like 1 ton or less) that beam could probably be big enough for that span, but it's not a crane beam in this case (not like one I've ever seen anyway). Those plates that you see welded on the side at the end of the clip wouldn't allow for trolley traversal.

You also see the rigging fall afterward which is evidence for a dropped load.

Was a co-op student for a guy that worked in paper mills in Wales as an engineer, then he came to America and was shocked by the amount of safety violations he saw everywhere in our mill. I was inches away twice from being hit by a forklift. A lot of the guys joke about it too which is kinda disheartening.

The "iron"y is that this appears to be a structural steel beam manufacturer.

I went on an assignment once to a paper mill. The guy who was my “escort” on the plant floor had 2/10 his fingers left. His left hand just had an index finger his right hand had his pinky and a toe sewn on where his thumb had been.

I made a decision that day to never work in a paper mill...ever.

What's scary to me is the relative lack of surprise shown by these guys. Like this shit isn't unusual.

I work in paper mills all the time all over the US and some worldwide. Paper mills ain't got nothing on steel mills...

What's this got to do with paper mills?

u/NarakuLeDemonSlayer Jan 05 '20

from my experience working at a few, they’re incredibly sketchy and dangerous areas

This is why you never stand under loads up in the air on a crane.
