How tower cranes are built 

Bro am from a tiktok that was asking this question😂😂

Facts

Tg thats why ime here

My question is how the guy gets up there

Only reason I clicked

Well I mean it is a portable one

@@GooseCrack but how is it made lol they would need another crane to build that crane tall enough

@@brandonsalas7731 hahaha I was thinking the same thing. Just as I was about to sleep I was like hold the fuck up, what about the cranes that built that crane…

“OMG THE CRANE SPAWN RANDOM” “FR- LUL”

They build themselves as seen at 2:57

Lego they build themselves bit by bit

​@@hewster1wow that's brilliant

Not all the time. Some cranes start with the top and build themselves from top down. They use like hydraulic lifts to lift the crane up, put the new section in and keep repeating

@@idontknowwhattosetthisto fried

@@idontknowwhattosetthisto There is always another crane needed for assembly

Seeing cranes self assembling is rare and maybe not visible because they are rising at low speeds. Cranes that are in buildings are lifted diffrently, it is mounted in the building and able to lift itself up to diffrent floors. Theyre mostly dismantled by Mobile cranes or special disassembly cranes. Some parts may remain in the buillding, but most are able to be removed

yup you use a crane to make or deconstruction another crane

Those cranes in the middle of the building are usually put in the emergency stairwell with tie in points in flooring, when the jobs finished the base remains and stairwells are added. Hydraulic cylinders with outriggers lift the crane towers up while a new section is added to the base via trolley. That's how they gain height

@@boeystuffinaround5290 interesting thank you

@@boeystuffinaround5290 do u do this for a living? I might be looking for trained personnel soon

I saw the exact name meme lmao

bruh sameeee

Same

Same, not from that Tik toxic

Same meme, I've seen

I would hate to be a construction worker being near those things since your life is totally dependent on their skill and everyone that constructed it. I could imagine you would have very little time to react to an error unless you knew what to look for and the "grunt" level guys probably know little about the cranes weaknesses or might just be busy not looking when an accident is about to happen.

exactly what i’m doing now

Mobile cranes or Crawler cranes are built in factories

Luffing towers typically have more versatility. When they are boomed up higher they can have relatively high capacity for a tower crane. Also being able to boom up higher and tighter allows them to avoid swinging into buildings when not in use. (Tower cranes are meant to swing with the wind when they are off). Also being that they only need to be boomed out as far as they need to reach, they dont have to fight the wind and torque as much as a hammerhead tower crane or T top. The benefit of a hammer head tower crane is simply just the range they have, and also the speed in which they can reach those far away ranges. I've operated towers with a jib that is 240 ft long, which means you can reach anything within 240 ft of the tower. You can also trolley out thst distance very quickly. When reaching out far with a Luffer once the boom angle starts getting lower and lower the horizontal distance traveled becomes very very slow. You would also be hard pressed to find many luffing tower cranes with a boom that long. The longest luffing boom tower I've ran is 180ft. Generally, luffing towers are better for going high, and T tops are better for covering more ground. Hope that helped.

In a factory

U don’t

It's a portable crane

It could, but it wouldn't really be practical. -The individual pieces would need to be more complex to make, bigger and heavier. You would also have to add extra parts and pieces to the for the actual elevator. That all adds up to a far more expensive crane. -It would also be a lot more difficult and burdensome to put together, which would slow down the building process and increase the cost of labor. Also, given that some projects need multiple cranes and you'd have to take all of the cranes down after the project was complete would multiply the lost time. Given that cranes are just tools to constructing a building, it would be problematic if they took an unnecessarily long amount of time to build. -The ladder within the crane is used for the construction and deconstruction of the crane. Every time a new piece is added or removed, the workers need to properly connect it or disconnect it from the tower, meaning that they need to climb up the tower *during* construction and deconstruction. If you have an elevator shaft, then you'd need make both a ladder and an elevator, which kinda defeats the purpose. -Finally, cranes are made to be as balanced and stabilized as possible, despite dealing with wind and moving large items around. Having moving parts within the tower and making the top part more heavy (as the elevator would usually stay at the top since the person used it to get up there) would negatively affect it's balance and make it a lot less stable. The entire design of the crane would have to be altered to account for that, but that would make it more clunky and expensive. It would be convenient to have an elevator, but if the person isn't afraid of heights and doesn't mind a bit of a workout, the ladder option is a lot more time-efficient, cheaper, stable, and easier to build.

Overall length used is installed first. Just picture 100ft of cable but only using 50ft then when crane is taller they use more cable from the reel.

Same process just reversed.

They retractable cranes on the back of trucks, I do commercial construction

so you think you are better huh?

Yeah that's insane!

so thats why i think they just appeared out of nowhere.

Mobile cranes are built in factories, their booms are telescopic, so theyre able to rech high enough to assemble a tower crane

A crane operator just fell from a crane at my job that’s y I’m here

Mhm

I guess only you

Stfu

Yup

No
