Tower Crane TC7021 FAQ:

1.What is tower crane?

Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.

2. What is the meaning of the tower crane’s code?

Take Tower Crane TC7021 for example, the first two letters “TC” means Tower Crane, “70”means jib length is 70 meter, and the last two letter “21” means the tip load is :2.1 ton.

3. What is the principal to quote the right tower crane to the client?

First, we need to know clients’ requirements,for example, max lifting capacity, height, tip load and jib length.. Second, we need to know what the foundation requirement from the client is and Third if there are special needs. CNBM could suggest proposal according to clear data provided by the clients.

Q:Some of my friends are trying to see what is the most creative, yet still meaningful way to ask a girl to prom. I decided to use 1000 origami cranes, and for those who don't know, the meaning (in Japanese lore) behind 1000 cranes is that the maker gets to make one wish, and its also traditional to give them to someone to wish happiness and prosperity upon them.
I love the idea!!! it's really cute!!! I have the perfect idea...it just hit me! MY IDEA: Do you have a lake or some type of water flowing in your school yard? Trees too? If yes, then here's the idea: 1. Put some type of plastic wrap at the bottom of each crane so they can float on the water. 2. Hang those oragomis you've shown in trees. 3.Have one of your female friends get her and bring her to the area. 4. Then when she's wondering what's going on....here's where you come in. You said that 1,000 oragomis stand for a wish right? This is what you say with a crane out of the water in your hand: Behind these cranes, is a maker who has a wish. When you hand her the crane, she'll get the point. Hope she says yes! And if she says no, screw her! I wish the guy who asked me was that creative. Any girl should happy to have a guy go through this much just for her. Good Luck Dude!!!!!

Q:my HSAP prep teacher wants us to find instructions on how to make an oragami crane.She said that it has to be less than 24 steps.I have looked on the internet and I cannot find anything.I need this by tomorrow.Please help!
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
Q:How much does it cost to build 18, 22, 35, 40, 50, 70, 100, and 120 ton cranes?
You would have to contact the crane manufacturer. Each size would have different cranes that meet that requirement, eg portable versus not portable. That's assuming those are total crane weight numbers? Or are they lifting capacities?
Q:I am NCCCO certified here in the US and would like to know how to be able to work as an operator in France.
Me too(NCCCO) how long for you? What do you run? I run a Terrex/demag a/c 140, Grove TMS 870, and a little national 40 ton. Anyway, sorry I don't have an answer but the other day just for kicks I was looking around to see what's going on and searching crane operator+job and there's a huge worldwide company, slips my mind but they kept coming up all over hiring operators all over the world. Give that a try, if I was single I'd be going everywhere, and getting PAID to do it but my wife and kids mean too much to be away. Try this.... search crane service+france email some crane outfits and ask around, it can't hurt.
Q:I saw da construction of the upcoming tallest building in da world in Dubai,how did da crane get on top of it?
it climbs the tower as the tower goes higher. the crane has 8 mechanical legs that it lift it self mechanically.like a spider in a tree or as the tower goes higher workers add a piece at the bottom of the crane using hydraulics
Q:WHAT IS A WADDLE CRANE?
This okorder /
Q:how do they make those tall cranes so TALL?
They come in sections. First few are fitted with a smaller crane anthe rest fit onto the side of the assembled base and are lifted up via the internal lifting mechanism then they just slot themselves into place forming another level containing a lift for the next piece and so on until the right height is achieved. I'm sure that's how it works. either that or it's magic
Q:Our company is responsible for the general contracting construction project foundation pile by Party A but other subcontractor for the construction of pile foundation of a pile foundation the company has quickly completed the construction scheme of the party and the supervision of tower crane foundation now has been reported by the audit Party B must contact us pile pile. We believe that Party A shall bear it at one time. Ask the net friend is this so?
In fact, in the long run, in a word, what the construction site is finally all party a pay, just clearing the count.
Q:Crane lifts a 600-kg bin with an initial acceleration of 2 m/s^2. Determine the force in each of the supporting cables due to this motion.?
F = ma Assume the crate is uniformly loaded, both cables will carry the same force F(AB)(4/5) = (600/2)(9.8 + 2) F(AB)(4/5) = 3540 F(AB) = 4425 N F(BC) = 4425 N F(B-Crane) = 600(9.8 + 2) F(B-Crane) = 7080 N As a form of exchange, please remember to vote a Best Answer from among your results. This is not the same as like or thumbs up which are also nice and do boost points, but only after asker awards initial points with their vote.
