- Q: National standards for tower cranes
- Tower crane GB/T5031 - 2008 has been implemented since February 1, 2009. In accordance with the new standards promulgated, chief editor -- China Academy of Building Research Institute of building mechanization of Langfang, Beijing and Hebei respectively in Hangzhou, Nanning held the new standards xuanguan. Luo Wenlong, director of the standard editor and vice president of Li Shoulin, explained the new standards comprehensively. The new standards are quite different from the previous standards, adding a lot of security related content, mainly embodied in the following 3 aspects: 1) the principle of different. Previously considered issues mainly consider the domestic tower crane industry technology status, appropriately reflect the advanced nature, and now is the requirements and international benchmarking, consider safety. 2) different forms of organization. The standard used in scientific research institutes, universities, factory assistant; the preparation unit including Research Institute, and the host plant, supporting enterprises, universities, inspection unit, there are relatively large units on behalf of (rental business), etc..
- Q: It seems like every time I turn on the news there is another crane collapse. I don't know if it is the same problem every time, but it seems awfully suspicious. Does anyone know why crane collapses seem so common lately? Has it always been this way?
- You okorder .. This chart is not definitive, it leaves out many occupations (such as mining), it only considers fatalities (not loss of limbs, etc.) but it conveys the general picture. For hard data look at: www.bls /iif/
- Q: how can we minimize energy losses of a crane to reduce the impact on the environment?
- No hint as to what type or size of crane, so I assume it is a large overhead traveling bridge crane inside an industrial building: Consult the manufacturer for recommendations. Change its power source to something cleaner (from diesel to propane or electric). Properly lubricate and adjust all moving parts. Turn power off when idle. Schedule heavy usage during hours of low demand of electric utility power. Replace motor with a more efficient new one. Replace entire crane with a new efficient one. Replace the large capacity one with one or more smaller units.
- Q: I want to know how to make the best and easyist paper crane with origami.
- find the instructions online...and fold them. crease the folds a lot so it is more crisp...that's about all i can tell you, because i can't give you the instructions.
- Q: i want to buy china tower crane,how to cantact the manufacture?
- Jinan Jinkui Construction Machinery Co., Ltd, one of the famous manufacturers for tower crane in China, has been rated the best suppliers in tower crane industry in China for three consecutive years. Also the exportation of tower crane has been taking a leading position in domestic China. The perfect after sales service is one of the reasons for you to choose Jinkui tower crane of China
- Q: If the crane Dawkings refers to about natural selection is not operating or existing by chance, then some questions arise:1) who or what is operating the crane?2) if its self operating, how is it programmed to do so?3) who made the crane?And about designing the designer, No one did. Otherwise the crane would be lifting the operator of the crane into the crane. I guess the crane can operate by itself, but then stopped doing so when something designed the designer. Too many philosophical conundrums for me. The belief in an unified, and self-complete, creator is far less of a complex explanation than the 'crane' concept with all its requisite philosophical flamings hog's heads.
- Bit by bit you may come to realise that complexity out of simplicity is much easier to comprehend than complexity from nowhere. The crane idea is from Daniel Dennet I think, and the boeing being assembled by chance is more or less what happened only bit by bit through evolution and natural selection. God is the complexity from nowhere to which I refer. Self-complete creator? did he make himself?
- Q: Calculate how much power the crane has?
- the crane ?? The crane is not defined.
- Q: I just wonder they use cranes at such heights, how do they carry the cranes at such height? Helicopter or something? This is a picture of what I'm talking
- The cranes are jack-up cranes. They have their own self-contained jacks. As one floor is completed, they jack up to the next level. The cranes are on top of the buildings. They are designed by structural and mechanical engineers to loift a given weight.
- Q: Do they need another crane to get the concerete blocks to the top? And how do they move the blocks from one end of the crane to another. This has been bothering me for some time so anyone who knows the answer I would love to hear it!
- Construction cranes are erected on site. They are usually assembled on the ground with small cranes, then lift themselves up. The erection sequence is carefully figured, so minimal other equipment is needed. For conventional cranes that are permanent and thus only assembled once, portable cranes are used to erect them. Still, generally pretty much on the ground. Some have counterbalances that are permanently fixed, others have a rail type mechanism that moves in and out.
- Q: A 3000-lb wrecking ball hangs from a 40-ft cable of density 10 lb/ft attached to a crane. Calculate the work done if the crane lifts the ball from ground level to 40 ft in the air by drawing in the cable.
- The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
