Did they have a solution for emptying the bigger container, or is than osha-all-the-way-down situation?

I worked at a paper mill for a few summers. There was this waste container that had 50-200kg paper rolls in it. Many tons of paper in total. The problem was, that it was on a ledge and there was no easy way to empty it.

The solution involved lifting the container in a tilted position and lowering it into a bigger container then opening the container door. The container had an open top so there was a risk of stuff flowing over. The belts that lift the container have loops only around the two crane hooks. So the four attachment rings rely on friction only to keep the belt from sliding.

After you had lowered the container into the bigger one, you'd climb onto a forklift's forks and open the container door handle by smashing it with a lead hammer. A clear risk of falling among other things.

Nothing bad ever happened, but it did feel so very wrong to see this big container lift into the air so tilted. They have a proper safe system in place now.

That reminds me of the video of the dude doing forklift acrobatics with containers full of salt.

There is no rectifier. It's a dropper circuit with capacitors and a resistor.

Uhhh, no there totally is:



It's hard to clearly make it out in the video, but that is what the 4-lead black component is. The only things I can clearly see on the board is that, a resistor, and 2 capacitors. I think there should be another resistor in there somewhere to make it a full capactive dropper + rectifier + smoothing capacitor setup, but either I'm not seeing it or that is the part where they cheaped out.

I mean, this is probably still dangerous, but the video is just wrong.

Ah good catch on the rectifier.
I was wondering why he didn't test the voltage at that metal plate. Now I know.

That part was decent. It was a container that a truck can pull onto its bed. There was a midlife upgrade to the OSHA solution too, using the forklift forks to pull down the lever on the container.

What up, fellow paper industry slave.

At work we recently had an employee fracture his foot by dropping a Supercalander roller on it.

Two people were transporting a 4.5m wide and 30cm-ish in diameter roller from a flat bed truck outside to a cart inside a hall. They decided to use a forklift and a pair of slings to carry it inside. Using only a single fork of the forklift as a pivot point so that they could get it inside the narrow doors.

As illustrated, not to scale. Not all of us can be artists:



Problem with this lifting method became evident as the strap on the fork slipped (as they had not put a bolt through the fork because they were in a hurry) and the cylinder dropped on the other guy's foot, shattering his metatarsus (and zeroing our new cool IT HAS BEEN XXX DAYS SINCE LAST ACCIDENT).

What the hell are you guys talking about?

The inner diameter of the wires is too large to fit the holes in the block, so multiple conductors are clipped off to make it fit. This might not be a huge issue by itself--oversized cable may have been used, so removing conductors leading up to a terminal connection might not cause any issues due to higher resistance (but if the cable was the right size, then the terminals might be underrated). The only problem I have is that the insulation was stripped away pretty far from where the conductors where cut.

Is that a terminal block or a termination?

Either way if I saw that, I would stop the work immediately.

Yeah, I have no problem with big clive's videos--he definitely knows what he is talking about. Watching this makes me realize what I missed in the other video--that there is no plastic diffusing cover in front of that spotlight. I had (wrongly) assumed it had been taken off or something, and that the light wasn't being sold with a bare exposed PCA

This was not a very good assumption on my part. Thanks, China!

Maybe I'm letting my imagination get the better of me but I just had a horrible "what if" scenario play through in my head. Would it be possible to fall through the ground and get cooked to death in an underground coal fire? Seems as though something like that going on underground would leave the upper layers structurally compromised.

State fire crews don’t usually aggressively attack coal seam fires unless they threaten life or property. That’s because noxious gases and the potential for firefighters to fall into burning coal seams during a ground collapse make direct attack unsafe, officials say.

It would be a horrible way to die. You would be sucked into the ground surrounded by smouldering earth.

It's absolutely possible. In the early days of the Centralia fire the ground collapsed underneath a 12-year old and he fell into a 50 m deep sinkhole. Fortunately the kid survived the fall and his cousin was around to pull him out before he suffocated from all the carbon monoxide in the sinkhole.

A fresh attitude
brewed daily!

The tires hooked up. If you watch the slow mo part, you can see the exact moment when the tires gripped and the wheel sheered the bolts off. When you're running a poo poo ton of power in a dragster, you don't want the tires to hook up. It's almost backwards, as at lower powers you generally want grippy tires that will help you get a lot of power down on the road. But higher-powered cars actually want their tires to be constantly slipping, even just a little bit, otherwise you'll grenade the gear box or something else important (like shearing the bolts off your wheel.)

https://www.youtube.com/watch?v=TZf9tXGPJNA

Not the best video to show it off, but if you trawl YouTube for some slo-mo videos of Top Fuel and Funny Car launches you'll see what I mean. It's also why the cars can sometimes get squirrelly going in a straight line - one tire is slipping slightly less than the other.
