Description of TC7021
1) CMAX TC7021 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.
2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected;
3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator

- Q: A few years ago, my college decided to take down two multilevel dormitories. The demolition company decided to take it down piecemeal with a wrecking ball. The wrecking ball was attached to the crane via a very large tire (just the rubber part, not the inflatable part). I have seen this done on normal cranes and other wrecking balls on TV and was wondering if any professional construction people out there know why they would do this as to me, a guy not in the construction/demolition business, think that might be a bit unsafe.
- It really depends on the terrain or the platform where this crane will stand.. If it is in a muddy or sandy terrain, then they may opt to use a chain tire. Cranes, dont merely rely on the tires. Cranes use outriggers. These are the extending arm of the crane. This hydraulically operated mechanism goes out of the cranes body, extends and extablished itself at four corners and sits at the ground to provide leverage for the cranes. This will prevent the crane to overturn when it is doing the operation.
- Q: how does a crane operator's knowledge of where the centroid is generally located for most uniform objects help them perform their job more safely?
- If an object is uniform, it's a fair bet the centre of mass will be at the centre of the shape. If lifting with slings, he will have them placed equidistant from centre, at an angle to each other not exceeding 60 degrees. He will then lift a little, and can tell by the angles from vertical of each sling whether or not the CM is under the centre of the crane cable. If not, he will lower the load, and have someone adjust the sling positions. Having slings equally loaded ensures a level load when lifting, and when a load is level it is a much safer lift than when it tilts one way or the other. A tilt would mean greater force in the sling on the low end. The load could slip out, or the excess force could break the sling.
- Q: How do you get a crane down from a tall building once it's completed?
- In the US most are called Tower Cranes and they actualy lower them selves down part way then using Mobile Cranes they diss asemble them the rest of the way
- Q: It's got to be the most famous of all designs in the art.
- NOOOOO! I can't! It frustrates me so much. (Got an origami kit for my b-day) But at least I can make a butterfly... and I used to know how to make a penguin when I was like 7
- Q: Could bird cranes resemble angels in appearence?
- Angels can appear as many things such as; Fire a Bird The wind a human Themselves invisible I had one wake me up once, kept shaking my leg! Amazing! It help save someone.
- 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 need help making a origami crane that can flap his wings.
- These okorder It takes quite a few tries to get it right, but once you do it is easy.
- Q: These cranes always stay higher than the construction process but I have never seen how they are extended to stay above all of it. They come in two formats, free standing and those attached to the building. The possibilities that I thought of was that maybe they use another crane to lift the housing and the horisontal arm to put in more modules into the vertical part; or that they extend it by some way by putting modules in at the top or bottom and that the crane has some self-lifting mechanism to accommodate the insertion of more modules. However, I have never seen this being done, nor does the construction of these cranes point to its ability to do so. The only other possibility that I could think of was that the crane is set up at the outset to be higher than the completed height of the building, hence there is no need to extend it but this does not explain how they do it for very high buildings where the crane is attached to the building and seems to grow higher with the building.
- In very tall buildings the tower crane's vertical frame usually sits in an elevator shaft. Initially it sits on its own base but as the building gets higher the crane is lifted using hydraulic jacks locked into the floor or floors above as they are completed. The construction of these cranes is rather ingenious in that they can dismantle themselves and the respective components lowered to the ground.
- Q: Can anyone tell me the location of the barn in the water color Waiting Refuge by Jon Crane or how to find it
- several times and have not found the print. However, these people specialize in Jon Crane's work and may be able to help you nail down the location of the barn in the print that you are interested in. Good luck. I hope this helps. ***I'm wondering why this is in Books and Authors? Are you searching for a book that contains this information or perhaps a compilation of paintings by this artist? I haven't found anything like that yet.***
- Q: I'm trying to workout the best height of a truss for a ship-to-shore container crane project. The crane will have a 65m outreach, 18m center section and 15m backreach. I was thinking in the region of 2m-3m truss height.Any input would be great.Thanks
- Jimmy: The American Society of Mechanical Engineers (ASME) produces design standards for many types of cranes: see the link below. Many crane owners, licensing and governmental authorities having jurisdiction over cranes require design, fabrication and testing to ASME standards.
