7 Dwarves Mine Train track.....now onsite

[juan]

Good Points.

But the sections of lift track weigh a lot more than a simple truck mounted crane could handle, probably more than the I-Beams they had to hoist into place with the big cranes. There isn't any cheap crane which is easy to setup which could be used to move the track lifts from where they are, closer to where they will be welded into place.

Since it sounds like you were working on a residential project, most of your cranes probably wouldn't handle the load, these sections of lift track weigh a lot more than a skylight I would guess.

I would have to disagree. While the track is heavy (maybe 2 tons per section), it is nothing compared to what an easily transportable mobile crane can handle.

look at their variety of cranes and capacities (I've personally used a variety of their cranes)

And by comparison, the maximum take-off weight of a fully loaded 757 jet is 127.5 tons (wikipedia)

Not sure how cranes will get in there now as floors have been built underneath the support pylons.

They can drive in under the rock archway by Little Mermaid and park near the attraction. They have long booms too to reach everything.

If I had to do the job, I would use a suitable dollie/truck to move the pieces to the construction site. And remember, they've built a floor underneath the support columns. I would go with a combination of power wenches/pullies to deftly maneuver the needed sections of track into the building, though obviously there are other options.

C'mon...how many residential projects require cranes to lift steel work?

Also, how do you suggest that they get the track pieces on and off the truck that you propose to move the pieces?

You seem to be digging your hole deeper and deeper!

I was talking about a crane which could be setup to move the heavy track pieces from where they are backstage, all the way to the construction site. In such a case, we're not talking about the max. weight the crane can safely lift, but distance.

Ah, I'm talking about the lift hill which has a roof and at least one second floor has been added below the support pylons. It is going to be very difficult to maneuver the lift track in here with any truck mounted crane.

Where exactly do you propose using the crane?

I do institutional, not residential, work. My current project is a 6 story, 160,000SF+ building. The top and bottom chords of our trusses were W14x550. Let me know if you want me to explain that.

Fork lift it onto a flatbed truck, drive truck into park after hours, stage pieces near ride, fork lift/crane a piece up and use boom to get it near mountain, put a monorail hoist on the beams, hoist piece into place

Agreed, more or less. I think this is why they built the mountain's backbone before the adding the track, there might even be overhang of the mountain structure where they don't need a boom.

I didn't know what type of construction project you were working on, just guessing. Six stories, eh? About a 14-inch by a 46 foot truss, eh? Can you pick-up something like that at Home Cheapo?

Seriously, though, my first construction job was framing a house for a Habitat, didn't have no fancy dancy cranes or the like to help with roof raising.

W=AISC Shape - "I-Beams" are most commonly W sections. There are also S sections, but they are not commonly used in construction any more (though they are used in elevator machine beams for some reason.)

14=Nominal Depth - a W14 is nominally 14" deep as you guessed, but it varies with the weight, and it's not impossible for a member to be deeper than indicated given it's weight.

550=Weight per foot. The top and bottom chords of our trusses were 550 pounds per linear foot.

Not home cheapo, but the cranes did come from a service very similar to Sims.

We also have a couple 48" deep plate girders. Those things are monsters.

Very interesting. I assume you are talking about the dead load of whatever truss you're building, not sure which of the chords you're talking about here. I guess its not a steel bridge that gets snowed on in winter.

You're the right one to ask any questions concerning a live load on the mountain structure already in place, in terms of monorails and moving the lift track around, I would assume that it would easily handle the weight, especially since not all of the mountain structure has been put in place above/around it, no doubt a lot of rebar and concrete.

Can we please stop talking about cranes and construction on stuff that has nothing to do with the 7DMT. And I thought I'd say that I thought track construction wouldn't start for a few more months.

How rude. He was simply qualifying his remarks to someone who doesn't want to believe anything that he has been told. If you don't care, then don't read it.

 

[sshindel]

There are ways to move around pieces of track that size without a crane.

Forced Dwarven labor? Hi ho, Hi ho, It's up with the track we go...

Seriously, these forums educate me so much on construction at times that it makes me want to pull an Office Space and give up the desk job and pick up a shovel. Then I remember how inherently lazy I am and turn back to the mouse and keyboard.

LOL, Maybe they could put Grumpy into one of these babies:

I've never seen someone babble so much trying to make themselves sound knowledgeable about a subject. The only people you're fooling here are laymen. You can't pretend to be familiar with terms like dead and live load, but unfamiliar with AISC standard terminology for steel beam types. Please give up before you continue to embarrass yourself.

And also, really?? You think they would need to put up a crane that could transport the track sections all the way from the grassy knoll to the construction site?? Why not erect a crane that could have just picked them up from the fabricator's shop and dropped them at the site.

I too am hoping for an early finish. My wife and I are going October 2013, and I would love to be able to ride it. If nothing else hopefully most of the construction is done so we can see what it will look like.
