Q:how does the power electronic drives employed in cranes?
Most large cranes run electrical motors. Depending on what power is available at the site, the crane may run from a generator or be powered by the grid. The power requirements depend on the size of the crane. Larger cranes may use a six-pole, three-phase, one-wye, 440-volt circut. Smaller cranes could use a three-phase 220-volt circuit.
Q:Explain how the idea of a counterweight used in cranes or in stand up basketball hoops relates to the concept of torque and equilibrium?
Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left). If you find this helpful, please award Best Answer!
Q:How do those cranes that build skyscrapers that go up with the building get back down after it's completed?
The top sections of the mast beneath the crane are removed one at a time and lowered to the ground. The top section of the crane has hydraulic rams that lower it down one mast section at a time. It is hard to describe without a diagram or photos. See photos at attached link. In some design, the jacking portion is at ground level. The crane jacks itself up so a 20' section of the mast can be unbolted and slide out. Then the jack is lowered so the process can be repeated. See second link for photos and a more detailed explanation.
Q:What are the impacts of construction cranes on the human society?
construction cranes enabled the building of multiple story buildings which fostered urbanism. It changed the village oriented way of life in America, for good and bad. We became more boadly oriented in our business ventures which increased the stanting of the U.S. in world affairs, but it decreased the degree of brotherhood people felt for each other as they left their roots and dwelt amongst relative strangers.
Q:Why do tower cranes need to be fabricated?
Cement prefab, are generally large components, especially bridges more, including buildings, these components of large size weight, super wide is the transportation, these components must be used crane, crane can meet the needs of the heavy transport of goods.
Q:Any idea what patterned reality is (technique used in Crane's The Red Badge of Courage)?

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 the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q:why are tower cranes positioned the way they are when they are shut down for the day?
I would think it's wind-related. If they were all pointed differently, one would catch more wind and spin more. If they were close enough, this one may hit another. If they were all pointed the same, this would be less likely (although not guaranteed). They SHOULD be spaced apart sufficiently, though, so during operations there is no chance of hitting another. So, it's more likely because of something on the ground. Maybe at last drop off they were all pointing in the same direction?
Q:Does anyone know the name of the mansion that is used as the Crane Mansion from the soap opera Passions?
