Features of 2015 hot sales tower crane tc4808
1. The tower crane comprises a number of mast sections that are highly interchangeable. The elaborate structure makes it easy for mounting and dismounting.
2. The main support of the mast section has both end faces processed by the jig boring machine to live up to the required flatness of both ends and verticality of the whole mast section, thereby improving the overall performance of the tower crane.
3. The metal parts are jointed by carbon dioxide gas shielded arc welding to achieve a tough and reliable structure.
4. Product quality is further guaranteed by the advanced inspection devices, such as the ultrasonic fault detector and sound level meter.
5. A complete set of safe and reliable hydraulic jacking device is adopted for self-elevating. The tower crane goes up and down steadily and the lifting height varies with the building height. These merits make the lifting equipment ideal for high-rise construction.
6. The cargo boom with triangular cross-section performs with double lifting points. It features excellent rigidity and convenient installation.
7. The hoisting mechanism provides slow dropping of large load in position as well as prompt lifting and dropping for small load. Thus the working efficiency is significantly improved. The lifting speed reducer is purchased from notable manufacturers to ensure that the tower crane works stably with low noise and high reliability.
8. Our self-erecting crane makes use of the single row four-point contact slewing bearing manufactured via advanced process by Hoesch Rothe Erde in Germany. This slewing bearing offers fine rigidity as well as excellent bearing ability of axial and radial tilting torque.
9. The slewing device comprises hydraulic coupling and planetary gear reducer, thus it enjoys high torsional capacity, high transmission ratio, compact structure, steady operation, and low failure rate.
10. The speed of the hoisting mechanism and the slewing device can be regulated by the winding wire motor and resistor to smooth the moving process and also prolong the serving time of the tower crane.
11. The components of electrical system are made by well-known enterprises in China and they are stable and reliable in performance.

- Q:What is the standard weight of a tower crane for 1.6*1.6*3 and 1.6*1.6*5m? Kg?
- The standard weight of tower cranes for 1.6*1.6*3 and 1.6*1.6*5m is 500KG
- Q:please tell me thats not what i think it is O_O
- It probably is what you think. I've heard that they use whale parts to make some brands of lipstick so I wouldn't be surprised if they used parts of other animals in cosmetics. =X
- Q:Yesterday around 9pm I saw a crane fly flying around my living room so I got a pillow and threw it over it. Sadly it found a way to get out cause when I was going to the bathroom I saw it right by the tub and I ran out. Those things are always trying to fly to me. Anyways there attracted to light or whatever so I just turned off the light in the bathroom and living room, and shut the door! I heard my sister later in the night go in there but idk if she saw it or not. So should I just go to the bathroom or wait till my sis goes in there?!
- Crane flies are totally harmless. Don't worry about it.
- Q:Who is the most gruesome Stefano DiMera or Alistar Crane?
- Stefano DiMera
- Q:Wall mounted tower crane

- Q:Why does the correspondant keep repeating If i am going to be drowned? IF I am going to be drowned -- if I am going to be drowned -- if I am goi
- I like Persipho's answer. But I have to disagree on one point. Nature is not hostile. It's indifferent. If you try to swim the English Channel and are able to go 21.5 miles instead of 22 miles you will drown. Nature doesn't care if you go all that distance just to drown, This is the irony. It doesn't matter if you go 10, 15 or 21.5 miles. If you get a cramp you will probably drown. Nature doesn't care. That's what the correspondant means. In the story a bird watches them and is completely indifferent. The indifference of nature is part of the School of Naturalism that Stephen Crane, Jack London and others belonged to.
- Q:Hello, i am goin in on Dec 5 to write the millwright C of Q for the 3rd time. On the test there was a question that went something like this The crane is rated 40Ton, with a boom lenght of 40ft and at an angle of 70 deg. The jib is 8ft long on a 10 deg angle. What is the sefe working load. The numbers are not correct but that is how the question is phrased. Please help me with the formula. I cannot find it anywhere.
- Normally you would get a chart for that crane and you look up the SWL at the extension and angle you would want to use, but you can calculate this too. Basic formula; mass*distance = newmass*newdistance, in the case you have described you have to take into account that the distance is not the load arm as it is not at a right angle to the force the mass has and therefore you would have to work that out via trigonometry. Any clearer?
- Q:feminists always point to sexism. but Ive found 3 women here - who say they have experienced no sexism, and were pleasantly surprised by how excepting their largely male co-workers have been -
- Have you failed at something? A physical for a job? Have you failed a civil engineering exam? Why take the blame yourself. Scream sexism By the way most crane operators don't pee out of the crane. Most urinate into a bag of gelatin that can be disposed of later. There is a special cuff for females to use with the bag
- Q:Do they have any symbolic-ness about them? any thing like that is good! THank you!
- The oldest living crane is Wolf which was a captive Siberian crane who lived up to be 83. There are 15 species of cranes living today and nine species that died a long time ago. The demoiselle crane are very high fliers flying over the mountains in the Himalayan Mountain range. Cranes are related to the rails coots trumpeters and limpkins. The western whooping cranes population migrates through the great plains to coastal Texas and the eastern whooping crane population migrates from Necedah National wildlife refuge in Wisconsin to Florida.The scientific name of the whooping crane is Grus Americana. Black-crowned crane is near threatened because of the pet trade.
- Q:They seem to be the tallest thing around, so what put them up?
- They are self-elevating. They jack themselves up. It was the invention of the self-elevating crane and the self service elevator which made popular tall buildings. In older cities, such as Paris, the height of a building was limits by the number of flights of stairs people were willing to climb.
