Never Stand Under a Load

Reminds me of a comparator that I was moving with a forklift...

All those people standing around with out eye protection.

As to the lift, I have a feeling it was a freak accident, I'm not sure what the safety factor is but it should be sustantial for something that is land based as opposed to aviation where the factor is trimmed a bit.

Well, in the beginning they state that the rotor weighs 75 tons.. Then towards the end, they show the placard that clearly states the crane is rated for 60,000 KG, which equals ~ 66.14 tons.. Or maybe that was just the support bar.. either way, someone somewhere made a mistake. Freak accidents should not happen with something that weighs that much.

60,000 KG is 60.000 tons.

Good eye on the placards.

Back in my youth in the army, we moved missile sections around with an overhead crane. As I recall, we load- tested *everything* - crane, lifting jigs, straps, every six months.

A load test on this crane before the lift would have prevented the accident unless it was a *real* freak event.

60k kg --> 60 tonnes (2200-lb tons), not 60 (2000-lb) tons. 1 tonne==1000 kg, 1 ton==2000 lb

Close, within 10%, but no cigar. KG = 2.2 pounds, T = 2,000 pounds.

In the metric system, 1 ton = 1000kg. That is a definition.

You're right. Since the accident happened in Metricville, I sit corrected. FWIW, we call that a "metric ton" over here.

I just call it a ton, and I call 2000 lbs 2000 lbs.

Yabbut, you grew up in Metricville and we grew up in Poundville.

When I think about how "short tons" are used, it is always the equivalent of "Sears horsepower".

Nope wrong again! I grew up in Canada in the 1950-60's which was very much Poundville. Went through the joys of metrification in Australia, then again in Fiji. I'm now retired and work as a volunteer at a Science museum where I refurbish ancient machinery. Most of it is Imperial sizes again. No wonder I keep a conversion chart as close as possible.

Yabbut, -you're- not Iggy, whom I was quoting there. Silly wabbit. Kicks are for Trids.

With that background, you should already know the conversions by heart, having memorized them 3 or 4 decades ago.

Learning metric so many times is why you're so grumpy? ;-)

I do know most of the conversions by heart including pressure a lot of the others, but a metric/fractional imperial/ decimal imperial char is a lot quicker.
