Crane operator here.

Leaving the hook or block in the air is an acceptable and safe practice as it is not something that can be removed each day. However leaving a load such as a generator suspended attended is illegal but rarely enforced. Cranes actually have to leave tension in their rope which is achieved by the block or else it can cause improper spooling and potentially rollover on the drum if there is slack from letting the hook touch the ground.

In regards to the cable they are inspected or atleast are supposed to be each day by the operator, however it is steel and it will fatigue and break overtime allowing the wires to be exposed. Under CSA Standards the acceptable amount of breaks is 3 per strand, 6 per lay and 12 in the entirety. All rope will or atleast should have some type of lubrication on it to prevent corrosion as corrosion is one of the leading causes of failure for wire rope and it would be possible to slide down the rope without looking like you are covered in grease.

The crane operator could not lower the block as one cable goes down while the other goes up and she would likely get pinched in sheave (pulley). I watched the rescue and they way they did it was fine, fall protection and and rigging of the rescuers looked proper.
Did the crane operator lower the two of them, or did the firefighter use his own equipment to lower them both?

The fireguy used his rescue rope to descend. The crane's cables, which is called rope according to our resident crane operator, was not used.

There is the appearance of two cables, but it is just the one cable going through the block. So if used, one part is going up, while the other goes down.

According to the guy who rescued her, she was covered in grease.

According to our resident crane operator, Up North, the cable is covered in a corrosion preventing lubricant. This is not grease and her appearance of being covered in grease is just the dirt that is stuck to the lubricant on the cable.

But, that hook or block was suspended 12 stories high. That sounds pretty high.BTW: I am aware of at least one crane toppling over in NYC.

Okay, so she was covered in a corrosion preventing lubricant. The guy who rescued her called it grease for lack of a better word. Same difference.

What does it matter how high the block is suspended?

The block didn't cause that crane topple over in NYC.

To the best of my knowledge, the cables are not covered in grease. Grease attracts and holds dirt and that isn't good for the cables. Grease is also slippery and cable slip is something you want to avoid with heavy lifting. That isn't to say that some grease doesn't get on the cables, as every pulley has some grease on the bearing which can get on the cable.

Frayed cables are no good in cranes. This shows signs of wear and too much is a hazard. It would also cause binding in places, affecting the smooth operation of the crane. Theses are inspected for things such as that. Not to say that there was no fraying, but with what these cranes are doing, a cable breaking would have a disastrous outcome.
Crane wire rope (the correct name is wire rope, not cable) are definitely greasy, trust me. They are made of steel and if bare steel gets wet, it corrodes very quickly. The grease is a light coating of a of both a penetrant and a protective grease. It's not caked on, but it's there.

And I'm not talking about a frayed cable. It's more like you'll see little barbs because of the way the wire rope is manufactured. You basically have a series of individual strands that are wrapped in a specific pattern, then those cables get woven into the wire rope. There are hundreds of individual strands that give you redundancy. It is not uncommon for individual stands to break from time to time and form a barb.

The fire captain who rescued her apparently invited her to the fire house for dinner. He was impressed at how she got up there.

Wonder if that invitation would have gone out if it were a hairy old man up there instead
No, of course not.

Can't say I blame the fire chief either, he just wants to get to know her a little better :eyebrows:

Are you going to tell us how much you think the whole rescue cost? I am really curious of how distorted your world is. If you can get bullied and cackled out of a forum and then come back under another name to join up with the cackler to bully other people. You must live in a Bizzaro world.

Kind of funny and entertaining for an otherwise boring time of the year.

What always amazes me is the amount of cops and firemen who are sent to these types of things. It is always severe overkill.

Even highway fender benders. I have seen 2 firetrucks, and 3-4 cop vehicles for a simple accident.

Apparently, cops and fire will no longer respond to calls to rescue cats from trees in Toronto.

I can't see $100 per hour cost per man. Our union guys might cost $50 bucks an hour with all in. In any event, it sure would be a lot of money.
Not that she could ever pay it. I would bet that she is judgment proof and works part-time at Starbucks.

I thought it was rather odd to invite someone like this, sort of rewarding her for her stupidity and recklessness. Wonder if that invitation would have gone out if it were a hairy old man up there instead.
The fireman just wanted to get his rocks off. Nice move.

I think its fine she went up there and had an adventure, but its lame she did not get down herself. In this case she should have to foot the bill for her adventure... i.e the cost of rescue...maybe only the additional cost as all those guys were on the clock anyway....its probably less then $500.

Correct a cable aka rope aka wire is commonly a 6x19 build and is therefore 19 wires twisted to make a strand and twisted the other way around the core to make the entire rope. Every strand is slightly different but that gives you over 140 individual wires and will allow for broken wires due to fatigue and use.

Correct there is lubricant that prevents corrosion.

Correct and depending on the block and capacity it could be one cable to a dozen reeved through.
