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:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:I am 15 years old and into urban exploration. The only thing I haven t done yet is climb a crane. I don t want a big lecture on the dangers because I am fully aware of how dangerous it is and am also fully confident in my abilities. I am also ready to take full responsibility if I were caught. Although I know its Illegal, I don t know how Illegal it is and I would like to know the following...1. Will Crane Climbing get me charged with criminal trespassing?2. Will I get time in Juvenile?3. Is it possible that I could accidentally activate/deactivate something that would endanger the workers?4. What would happen if a worker got ahold of me?And again I feel like I need to mention that I don t want a Bull **** lecture on it not being safe. :)
Trespassing is illegal. How illegal? LOL... illegal is illegal. I'm not going to look up the possible fines for you.
Q:I don't like the cranes that use a wired pulley systems for controlling the camera.The crane will need to carry a 7 pound camcorder.

Q:Who was the guy called the Headless Horseman in the story of Ichabod Crane?
A Lib
Q:I'll be graduating from a Korean language extra school in 1,5 years, and one of the teachers there is really amazing. Essentially, she has taught me the most compared to any other teacher there.Would giving her a 1000 cranes (and a bouquet maybe?) an appropriate and good 'thank you and goodbye' gift? Is it too little? Or overkill? She really means a lot so I want to give something!
I think that gift would be perfect for a teacher! If I was a teacher and a student gave that to me i'd cry. Have you heard about that book of the 1000 paper cranes? (Can't remember the name) but it says if you make a 1000 paper cranes then you get a wish. Well anyways make sure you present the presents nicely. Like put the cranes in a pretty jar with a beautiful ribbon wrapped around it and get flowers that're her favorite colors.
Q:i really need help
Influenced by Darwin’s Theory of Evolution, Crane believed that people’s actions were determined by environmental factors rather than by conscious choices on their part. He believed also that conflict was the crucible in which human development occurred, and thus was attracted to the violent and seamy aspects of human experience.
Q:I have got a ton of Mosquito Hawks in my house. Should I just let them be or will the problem get worse? Plus I read they dont bite humans but will the bite rabbits? I have 2 house rabbits that I am concerned about.
So called mosquito eaters, mosquito hawks, or skeeter eaters. Unlike mosquitoes, crane flies are weak and poor fliers, so they can be caught easily and without much effort. Despite their common names, crane flies do not prey on mosquitoes, nor do they bite humans. Adult crane flies feed on nectar and consume roots such as turf grass as in backyard lawns.(So they won't be preying on your rabbits) Their life cycle is very brief, so you shouldn't have to worry about them multiplying. They are also weak and poor fliers, so they can be caught easily.
Q:will give you a wishor help your marraige succeedjust curious as to peoples thoughts?thanks lt;3 abby
no ive made more then that before and nothing happened to me
Q:How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
they fold up
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.
