1) JL4210A tower crane has 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.

- Q: How should I go about stringing paper Cranes together??I alreadly know how to make them, its just that I have no clue how to put them together
- Depends how you want to string them... but use thread and a needle. If you want to string them vertically, put the needle through the body of the paper crane... I not sure about horizontally. Too keep them in place, place knots below the body of the crane. I hope this helps, but I hope another more experienced person answers this :P
- Q: Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.
- I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
- Q: i saw a huge one look liked it had a stinger to those hurt u?
- Unless you are a plant, you have nothing to fear from crane flies.
- Q: Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?
- i hope this link helps
- Q: What is tower crane? What are the types and features?
- [definitions]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: She was editing some of his writings. She was appalled(prim proper Nebraska gal) by his lack of punctuation. He said he didn't have the time for it. He was right. Shortly after he died of TB. Do you ever feel that time is your enemy; that you have only so many years to make a difference?
- Due to my present situation, I have thought about this many hours. Many days. Many months. Time, or the lack of it, is generaly considered the enemy. But there are situations that the less of it can be a blessing. None of us can ever know which we will wish for. Until that time comes.
- Q: I'm into urban exploration and basically the one thing I haven't done is climb a crane. I don't actually know where one is that I could climb, but I definitely will do it someday. I'm just wondering how illegal it would be? Also, don't give me any it's not safe bull, I'm perfectly confident in my abilities and ready to accept the consequences if I get caught.
- Not at all if you don't get caught. However cranes are private property, you'll get your a.ss handed to you if you get caught.

- 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
- Q: Does anyone knows where could I find this book online and free ? I would love to read it from my tablet or computer
- The Lost Language of Cranes is a novel by David Leavitt, first published in 1986. So the author wasn't thinking about ebooks back then and never signed a contract to make ebooks. See if your public library has a copy in paper. Amazon sells it in paperback and hardcover. Anyone that has a copy for free has stolen intellectual property and is cheating the author and publisher.
