If you think it's scary just looking down, now imagine that you can drive and steer these machines while they're fully extended, and even with the boom swung out over the side. Top speed of about 0.5 kph.

My job is to fix these things and then test them. We have one 150' boom, and over a dozen 120-135' lifts. I go all the way up in one at least once every other day. All of them will drive (again, slowly) with the boom fully raised and extended, and even swung out over the side. That's kind of the point of using them.

I can't tell if you're being dumb on purpose or not. You quoted my post where I said that's exactly what they do. The only way to drive a boom lift is from in the basket. There are no drive controls on the ground, only boom controls.

I was just at a store buying some groceries and they had a sign that said "6 Years Accident Free!" and I had to laugh because that's so full of poo poo and I would be scared to work somewhere that goes through the effort to hide accidents for that long.

So one of our machines has been leaking oil and the solution the workers decided on was to put a bucket under the leak. Then when the smell of oil got to be too much to bear, the supervisor brought in a box fan to point at the bucket. Thing is, those fans have motors that can spark. Basically the supervisor rigged a loving bomb without knowing it.

A worker from Berwyn was killed and three others were injured early Tuesday when a 45-ton beam fell at a construction site in Des Plaines, officials said.

The workers were in lifts on Touhy Avenue working to remove the beam under the Jane Addams Memorial Tollway (Interstate 90) about 3 a.m. when the beam collapsed, officials said.

One of the workers was taken in critical condition to Lutheran General Hospital and later pronounced dead. Three others were taken to hospitals with minor injuries, according to Des Plaines Fire Chief Alan Wax.

The Occupational Safety & Health Administration in a news release late Tuesday said the incident was "preventable."

Since construction on the Jane Addams began last year, traffic in the area has been a "pain," Huerta said, but especially so today with the addition of the road closure.

That reminds me, a while ago the discussion involved forklifts and how far the forks should be raised while driving. I said I was going to pull out my training institute's publication on forklifts, but I forgot. I'll grab a copy right now while I'm still at work.

While I don't know which specific forklift you're talking about, most 5000 lb capacity forklifts weigh between 8-9000 lbs, which is still a lot heavier than I thought before I knew better. A 10k capacity would weigh around 15 000 lbs. Electrics I think are heavier but off the top of my head I don't have anything to back that up.

Rough terrain forklifts, and variable reach forklifts scale up way faster. A 5k variable reach weighs around 10 000 lbs, and a 10k capacity typically weighs over 31 000 lbs. They are impossible to see out of on the right side, and will (possibly , vehicle gets his by forklift, driver dies, but you can't see any details through the windshield) gently caress you right up if you get hit by one.

Fork height chat: The comments on that video are wrong; in a variable reach forklift you need to keep the forks high enough so that you can see what's going on to your right. Unfortunately that puts them right at chest height, so if you see one driving around, just stay out of its way.


Variable reach forklifts often have front-deploying outriggers for picking up heavy things that are far away. It's OSHA because guys forget to raise them before trying to drive away.

Ha, we had a fire safety class last week and the instructor specifically told us not to do anything dumb like try to stomp a fire out, but to always use the extinguisher. He also showed us a lot of hilarious (well, hilarious if you don't think about the amount of property damage and potential injuries and lost lives) photos of stuff he's actually found during inspections and after large fires.

They also did away with the fun part of the class which was when we'd get to practice putting out a real (small) fire (outdoors). Now it's this electronic video game type thing. It's like putting out a Lite-Brite fire with a laser pointer.

I think the Glen Canyon Dam takes the lion’s share of that, but of course when it fails catastrophically, Hoover will follow.

It actually does seem stupid to provide operators with factor-of-safety margins, because they think it means it's safe to exceed that. On aircraft designs, for example, the "neutral point" of aerodynamic stability is a very important and key piece of information which gets loving buried to prevent dumb-asses from trying to be Chuck Yeager or Bob Hoover in a plane not designed for it, then getting themselves into an irrecoverable attitude because they hosed up the CoG loading and the aircraft is completely unstable now.

Most load charts aren't based on the maximum possible capacity at that boom length and angle. They're usually based on something like 85% of the maximum. The intention is that operators will never go close to the limits and the slings are designed to be stronger than the minimum necessary anyway just to provide a safety buffer in case it does get overloaded.

The problem is that it's giving the operators just enough information to be dangerous. What's the old saying? "The only thing more dangerous than having no knowledge is having a little knowledge"? If a careless operator knows that the load chart is actually underestimating the capacity by 15%, there's a good chance that in a crunch (like when their boss is yelling at them to hurry the gently caress up, or they're too tired/lazy to go out and change the slings or get a new crane that can handle the load) they may go "Aww, I got an extra 15% anyway!" and lift something that exceeds the load chart.

What usually happens is that they end up actually reaching the maximum capacity of the crane, or the crane or slings are worn and the effective maximum capacity isn't the awesome "rated for 500% the list capacity!" on the label anymore. So they go up to 100% or 105% of the crane's capacity and tip over, or the slings snap because they've worn down to only be capable of 200% the listed capacity and are now at their limit. The true maximum capacity is the point where you're supposed to stop.

This is why when you're in between listed numbers on the load chart, you always use the next lowest numbers. If the boom lengths are listed in 10 foot increments and you're at 75 feet, you use the capacities listed for 70 feet instead of 80 feet. You always want to be operating within a good margin of safety, without maxing everything out.

Edit: poo poo, even the 1000 hours doesn't mean anything when it comes to actual knowledge. A lot of operators pick up really bad habits after years or decades without an accident. My training institute gets tons of people who have been operating cranes for 5 years or more and don't even know how to read a load chart because they've been eyeballing it and just been lucky. The precast guys we were talking to this week rarely even look at their charts closely because they're almost always lifting loads of known weights and just do the same thing over and over.
