Tower Crane TC4808 FAQ:

1.What is tower crane?

Tower crane is a modern form of balance crane that consist of the same basic parts Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.

2. What is the meaning of the tower crane’s code?

Take Tower Crane TC4808  for example, the first two letters “TC” means Tower Crane, “48” means jib length is 48 meter, and the last two letter “08” means the tip load is :0.8 ton.

3. What is the principal to quote the right tower crane to the client?

First, we need to know clients’ requirements,for example, max lifting capacity, height, tip load and jib length.. Second, we need to know what the foundation requirement from the client is and Third if there are special needs. CNBM could suggest proposal according to clear data provided by the clients.

Q:when a skyscraper is done being built, how does the crane come down?
Skyscraper cranes (for construction) are usually dismantled into small sections and pieces after final stage of construction is done. Some of the smaller pieces are transported down by construction evaluators, while bigger pieces are lifted down by series of pulleys or cranes mounted at the side of the buildings edge.
Q:How to subdue an injured crane?
If you have a pillow case then put it over it's head. then wrap say a towel round it's body to prevent any damage to it's wings and you. Then get it off to a rescue centre or vet/ Wildlife Warden
Q:A crane uses 2 kW to raise a 100-kg box 20 meters. How much time does it take?
We start using by defining mechanical Power: = P=Work/time What is the work here? We lift the box a given distance. Work=mgh Since we know the power of the crane, we can simply plug in the values and solve for t: t=mgh/P This is only true if the crane has a constant power, which seems to be the case LeSmartOne
Q:Why are there so many cranes in London?
At present a large number of tall buildings are being erected in London which accounts for the cranes. One area in particular is around Vauxhall, where there was an accident recently when a helicopter crashed into a crane being used for such a purpose. Just have a look at this www.guardian.co.uk/artanddesign/2...
Q:What is the definition of lifting, slewing and luffing of tower cranes?
Rotary is cantilever tower crane tower crane rotary shaft winding;Is the hook shaft distance amplitude change;
Q:how can i calculate size of battery and how can i design ups system to operate eot cranes which have 100 kw to?
To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
Q:We have a whooping crane living in the bayou.?
Want to help? Don’t feed them, which draws them deeper into dangerous urban areas. And try to keep reflective surfaces covered. Following these tips could keep these majestic citizens a little safer. In 2002, the Florida Fish and Wildlife Conservation Commission made it illegal to feed sandhill cranes. Why Is Feeding Cranes A Bad Idea? Cranes fed by humans can become aggressive toward people. In several instances, children have been attacked by cranes. Cranes fed by humans also have been known to damage window screens and do other property damage. This behavior is probably a response of the birds to seeing their reflection, bringing out a territorial defense behavior (scratching at windows or shiny automobiles). Cranes also are more likely to tangle in human garbage in areas populated by people. Cranes attracted to people's yards for feed are put at risk as they walk across roads. Many sandhill cranes are killed each year on Florida roads. Cranes are also more likely to crash into power lines in urban areas where such aerial hazards are concentrated. Attracting cranes to urban areas increases the threat of predation (especially to young cranes) by dogs or cats. Further, the cranes' diets, which normally are quite diverse, are disrupted when they eat one food item (such as corn), consistently. Heavy pesticide use in urban lawns also is of concern. Young sandhill cranes have died from pesticide poisoning. It's Never a Good Idea to Feed Wildlife People inadvertently put cranes in harms way when they attract these birds with feed. Florida sandhill cranes have an abundance of natural foods (insects and small animals) and they do not need handouts from humans. There are many reasons why cranes should not be intentionally fed by humans, so I hope this gives you a few you can communicate to these well-intentioned people. The bottom line message: For the good of the cranes, please do not feed them.
Q:why are siberian cranes endangered?
The traditional migratory and wintering habitats of this species are under constant pressure from the demands of the growing human population. These include: agricultural development, wetland drainage, oil exploration, hunting, and water development projects. The western population is primarily threatened by hunting whereas the eastern population is at risk from loss of wetland habitat.
Q:In what season does the whooping crane migrate?
The wild Whooping Crane flock spends its summers in Wood Buffalo National Park in the Northwest Territories of Canada. They nest and rear their young there. During the fall season, the Whoopers migrate 2,500 miles south to Aransas National Wildlife Refuge in Texas where they spend the winter and early spring. There are currently 193 birds in this flock.
Q:How do you hang origami cranes?
TAke a needle threaded with a long piece of black thread, and make a small knot at end of long thread. Push the needle thru the middle of the crane's back and pull the thread all the way thru the hole till the knot catches. pull the needle off the loose end of the thread and make another knot on that end. take a push pin or thumb tack and push the pin thru the knot, then push the pin or tack into the ceiling. FYI, tape never works - I have tried. The black thread lets them flutter a bit, and is invisible most of the time. p.s. ask your parents if you can hang stuff from the ceiling first. they may not want you to do that since it will leave holes in the ceiling when you take them down.
