China Tower Crane with CE certificate for Construction

Q: He has to be in his 30's to 40's but I can't find anything that gives me a definite age.: Okay Well, You havent specified in what, but presuming you mean in the comics, and baring in mind he was the psychologist when Thomas Elliot and Bruce were only 7-8, then the bare minimum he could have been then was 21, though he was likely older. THEN presuming Bruce is around 35, though he also is probably older, then the bare minimum Crane could be is 48. that being said, he is likely between 48-60. He just looks good for his age ;). this of course is in the comics, however. The movie is different.

Q: Recently, it seems that any time my front door is open for any period of time, crane flies start migrating inside. I would like to find a way to keep them out when the door is open. Are crane flies attracted to electric bug zappers?: Are you going to be councilling the fly in a few months time, or having to pay for it's bills when it tries to sue you for being made a cripple? If not, who gives a ****? It's dead. Flies spread disease also.

Q: Is there a crane lifting chart where I can enter info. to determine what size crane I need, if so where?: the 1st answerer, Irv S, is right. You need to call a craning service. They should be able to give an estimate for crane size based on what you tell them. You will need to know what your Load weighs. How high in the air the crane will have to lift it. ....Putting a swimming pool in the back yard is completely different ....than putting that same swimming pool up on top of a 15 story ....building. How close to the Load can the crane park? Or how far you need the LOAD moved. What a crane can lift, even if it a 100 ton crane is based on how far the crane has to reach to pick up the load and how much the crane has to rotate to place the load. The angle the crane boom goes to, etc. Our 15 ton PH crane can lift 30 thousand pounds at 10 feet from the Turning center. And only a 1,000 pounds or less if the boom is fully extended with the Jib on, that is 125 feet away from the turning center of the crane. Distance is critical! They will probably need to see the work site to give a really accurate answer. Wingman

Q: What kinds of concrete are there in construction crane? Mainly for the construction of this area ~ ~ ~!There is no lifting machinery issued by the state what ~ ~ which detailed description of the construction machinery lifting what?: The most common are tower cranes, elevators, and freight lifts. The big construction enterprise also has the track type tower crane

Q: How do tower cranes rise?: A tower crane raises weights by clicking on the reverse;Tower crane (tower crane) is called tower crane, also known as tower crane, 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..

Q: What is W_safe, the largest weight of the load that is safe to lift regardless of the angle of the crane's arm?: (Wc)/(2b) for my problem.

Q: The question is: A crane has a power of 500watts, and is pulling a 142kg. What is the velocity of the pulling of the crane?Please help and thanks!: I don't remember ever doing a problem like this, but I will try to solve it. P = W/Δt, P = Fd/Δt P = Fv Force required to lift the 142 kg object; F = 142 * 9.8 F = 1391.6 N Therefore; P = Fv 500 = 1391.6*v v = 0.359 m/s So velocity of the crane is 0.359 m/s. Is that right?

Q: This has nothing to do with travel, I'm just curious. I hate it when the news doesn't follow up on stories they focused on earlier. Does anyone have a status update on that crane that was swaying in the wind during Sandy?: My friend, that is a good question. According to the latest news conference from the Mayor, the crane's boom arm is secured to the structure. However, West 57th Street between Broadway and 7th Avenue is closed until farther noticed. In addition, the 57th Street-7th Avenue subway station on the N, R and Q Line is closed and trains are bypassing the station in both directions, according to the MTA. Good luck Native New Yorker
