Specification of our tower crane:
- Q: Like those huge cranes on the top of buildings that are being constructed - how do they get them up there???
- A combination of methods. Use a helicopter to lift pieces of a small crane to the top of a building and assemble it there. Then use this smaller crane to life pieces of a larger crane to the top of the building for assembly.
- Q: How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?
- Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.
- Q: I need to make a crane in my mechanical class. I can use anything pretty much (pulleys, levers, etc.) The goal is to make a crane with a claw that can pick up a weighted container in a tub of water. It needs to be operated by handle or something, and the base of machine must be on the table top. Any help will be appreciated.
- In the event that you need to discover pleasant thoughts for woodworking i can propose you to check a website ( ( woodworkingplans.kyma ) ) It's perfect in the event that you are simply starting out or in case you're a prepared carpenter. It has thousands and thousands of woodworking arrangements and you have a CAD/DWG software to view and alter the arrangements. You have regulated instructions with photographs and excellent blueprints and schematics. On the off chance that you are a beginner this is the simplest approach to start your woodworking projects, and on the off chance that you already have experience you can at any rate discover a ton of interesting thoughts!
- Q: I'm looking for estimate including installation, vertical support beams, and bus bars. Details: rectangular shaped building 500 ft long split lengthwise into two sections. 500ft X 4lengths of craneways is 2000ft. The crane runways are bolted to building frame but are self supporting on I-beams (104 vertical supporting beams X 24ft. height). The crane runways can support 10ton hoists. The bus bars (electrical conductor assembly) run along all (2000ft) of crane runways.
- the only 5'6 girl I know of who did runway was Devon Aoki. Everyone else is at least 5'9+ except Kate Moss who is 5'7.5. The average height for runway is 5'10
- Q: It's got to be the most famous of all designs in the art.
- Better yet, can you make an origami orgasm?
- Q: What does "automatic tower crane" mean less than 100 tons per metre?
- When you are working on this crane, the weight between the weight and the weight to the horizontal distance of the crane Center shall not be greater than 100 tons.For example, if the weight and crane center level distance is 10 meters, the maximum weight is 10 tons; if it is 20 meters, the maximum lifting weight is 5 tons; if it is 40 meters, the maximum lifting weight is 2.5 tons.
- Q: Grade 4 build a working crane Help!?
- I would use about a 2 foot piece of broomstick pinned through a hole in one end. Maybe 2 to 3 inches away, a larger clearance hole with a 1/4-20 nut glued under. Use a lo-o-ong 1/4-20 bolt as a driver. (1/4-20 is 1/4 inch diameter with 20 threads per inch.) I leave the mounts and string up to you as to encourage your participation and creativity.
- Q: What role does the tower crane torque limiter play?
- The overload protection of tower crane is protected by two equipment, lifting load limiter and torque limiter. The latter generally in the big arm root 4-5 meters to the front of the large arm, overloading (Chao Liju) work, it is more important, basically, the scope of work is torque limiter plays a protective role. While the former is the weight limiter function in the arm root within 4-5 meters, because the tower crane is a jib type crane, each allowing weight lifting position corresponding to the different (CAB load curve). For example, such as 63KN.M, the big arm root 2 meters lifting, the theory is 23 tons, while the torque limiter is not over, but in fact, the tower crane at early crouched down, so the weight limiter in this work.
- Q: How much should the verticality of a tower crane be controlled? Thank you
- No, the wind speed is not more than 3m/s, the independent state tower (or attached state highest attachment point above the tower axis) lateral verticality tolerance is 4/1000, the highest tower axis perpendicularity allowed attachment line below the point of difference is 2/1000.
- Q: which is crane lift planning software free to download?
- for spyware - download spybot 2008 (free n easy) for virus protection - download 'avast antivirus' (free n relatively easy) - both r good programs, just be careful with spybot - it is v. powerful, but luckily u can choose what to delete after it finds possible bad files, just dont let it delete any registry files (C/WINDOWS/System32) - these are important files - leave them alone unless problems persist - then get professional advice.
