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 is the common cause of crane accidents
- Although mechanical failure does occur, most crane accidents are caused due to human error. Here are some examples: 1) Operating a crane during adverse weather conditions, such as wind conditions 2) Overloading a crane/ improper load calculations 3) Inexperienced or untrained personnel 4) Improper rigging of the load 5) Bypassing safety devises 6) Improper selection of the crane for the environment (ground conditions, power lines etc.) based on the type of load 7) Shock-loading a crane 8) Failure to perform maintenance and inspections in accordance to manufacture specifications I hoped this helped Cheers
- Q: I work a few blocks away and my window faces the building, now shrouded in black netting and scaffolding. I cannot comprehend how that crane got up there!!
- First opf all structure engineer design the crane(wind Load+load carrying capacity+self weight+torsion+moment...etc) then designed in parts then fabricated with iron pipe, angles, girdrers. then transported to site on trucks then assembled in small pieces on ground then step by step joined with the help of crane, or even helicpoter(it was even used in CN tower)
- Q: What are the lifting moment requirements for tower cranes?
- 2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device
- Q: the question is :Two cranes can unload a ship together in 15 hours. The faster crane takes 16 hours less than the slower crane, if each were to unload the same ship alone. How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
- No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
- Q: is was about making this game where this guy knows crane style
- There okorder /
- Q: this wind speed refers to that height of wind speed?
- Surface wind speed is greater than 6
- Q: Because they look a lot alike. Such as if you reinforced the design a little bit will it work?
- It might - but the center of gravity and the tripod might not be able to hold the weight of the jib, camera, counter-weights... and personally, I think it would be a pretty expensive mistake to watch my $2,000 camcorder fall and brake because the camera crane collapsed under the weight. A mic tripod is designed to handle about a pound of weight. A consumer camcorder, the jib and counterweights (and maybe a mic or whatever else you throw on there) can be between 5 pounds and 50 pounds. That's why companies like Kessler make what they make. And that's why the companies that makes lesser camera cranes (Cobra, CameraCranes, and others) never use a mic tripod. They use a heavy duty camera tripod or other LARGE, STRONG, item - not a mic stand.
- Q: I was watching Batman Begins and at the end Gorden says that he hasn't caught Crane. Since the villians in the next Batman movie are going to be two-face and the joker will Crane make a reapperance in the thrid movie (if there is one)?
- Right okorder reported that an anonymous insider says Murphy will return as Scarecrow in The Dark Knight, but this is an unconfirmed rumor. Also, rumors are that Two-Face would not actually be the villian until the third movie, and that this movie will showcase him as Harvey Dent, the DA and hero, and show him on the path of becoming Two-Face.
- Q: I'm researching Stephen Crane for an English project and I need to how Stephen Crane's works effected others. Thanks for the help! xP
- I'd mention his book Red Badge of Courage and how it changed the war novel for American and English writers. You can look at books like Catch-22 , MASH, or Hemingway's war novels and find that personal voice that Crane used.
- Q: Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace for cooking? e.g. like in dutch ovens or pots/cauldrons that hang over a fire. It sounds like a more modern term and I need to know if there is an older term. Thanks.
- You would mean one in the hearth, yes. An older term may be to call it a Pot Crane or Chimney Crane. That is most common to what you describe that it is affixed to the chimney and swings about. That does not swing, a lug pole might be from a green wood or iron hung above the fire with chain ... or if a Hearth Crane then a standing legged trestle (stands upon the hearth) and hooks affixed ... some with a pot crane attached. But either. You might also refer to it with it's counterpart, the trammel ... as in crane trammel. The trammel is the device hung from the pole or crane to allow the pot to be adjusted up or down depending on the heat required. In some cases the trammel can be just a series of S-hooks linked together, it can also be a chain with hooks, and is often a specific toothed device wrought by smithy. As a child we used hooks and hooks chain, thoe as a man I owned a sawtoothed trammel but hardly used it as I'd obtained a stew stove. My business partner Ebenezer insisted that a toothed saw trammel was frivolous and kept a chain and hook type in his home.
