Crane Assembly

[jimmyj]

Hi:
This isn't anything to do with firearms, But:
The hospital I visit on regularly is building an addition.
The construction crane is approx. six stories high with a horizontal arm approx. 300 feet in length.
I am curious on how the crane control cab is gotten up the metal tower and how the horizontal arm is applied ?

I asked one of the construction workers this question and his answer was "I have no idea".

Thanks,
Jimmy

^^^^^^That was way better than any explanation I could render about how a "jackup" works. Joe

Strange this showed up here. Monday I took my son to the airport, and there were four of those cranes working on construction of a new multi-story parking garage. And I was asking myself "how the hell do they get those cranes up?" Another question - how does the operator get up into the cab? I didn't see any ladders, etc, and in any event, I don't think any sane person would want to climb that high on a ladder.

There are ladders inside the frame and yes they do climb them.
Not to many tower crane operators overweight with 100lb beer bellies.

Surprised no one came up with the method
It's really very simple.

They use a crane!

Thank you.

Had a friend who was working in one when an earthquake occurred. LOL, it wasn't that big of earthquake (Pacific NW), but, it pretty much cured him for the day.

Think steady full time employment and a $100,000.000 + annual pay.

My cousin ran the tower crane for a couple years that was high above the 44 story building in the South Mall in Albany NY (AKA-The empire state plaza)

i was working there and my cousin invited me to come up to the cab. Took the elevator to the 40th floor and then used the ladders to get the rest of the way up to the crane.

What a view! The cab is well air conditioned and heated and they even had a camper type Port-o-potty in it. Your not taking the time or effort to go down into the building when nature calls.

My cousin and the other operator stayed up all day. (rules they had to have two operators, one ran the crane and they switched off as necessary to stay fresh)

They had the cabin well fixed up including a small refrigerator, hot plate a good set of binoculars and a police and fire scanner. Sitting up there where they were they had a commanding view of much of Albany and the surrounding area.

As a union Ironworker, it was our job to put that type of crane together plus the others with just one jib.

Climbing up the section did get old but so did the heavy impact
and making sure you did not drop anything !!

On one "Take down" in Reno, my partner and I could see our refection's in the office glass windows, as we walked toward the tip of the jib, to disconnect the cables and start the dismantling of the crane.
The weather was calm and quite pleasant, until we cleared the one office building. That was when we were met with 40 mph winds that blew our hard hats off and made us gain our balance!!

As a note;
My first year on the job, I saw two cranes go over and another have its boom damaged from wind, as it swung into a hotel, for the operator not locking it in place, when he took off for lunch.

Cranes can be very interesting.

Here is a picture of a parking garage in Reno Nevada being built.
The rebar colums that you see being held in place by wire cables
are in real need of the Carpenters coming in and framing them with
wood frames, before something bad happens.

Heavy construction can be exciting at times !!

"Snap, Bing, BANG" !!

In NYC, the crane was the tool of the steel erectors iron workers. Our company's pipe-fitters would need to use the crane when it was available on Saturday's, to place long risers. The crane operator got his overtime pay of course, but didn't climb the tower until we put an envelope with an extra $5000 cash in his hand. The value he provided was easily worth it to us, and everyone benefited.

The Russians seem to be pretty good at it:
