Q:mobile tower etc (uk)
Tower cranes and Gantry Cranes Since toer cranes are the most used in the construction industry gantry Cranes are used in all Ports for loading and unloading containers has a vast scope of work
Q:please tell me thats not what i think it is O_O
Omg! What primer is it? That sounds really fishy...
Q:Cranes are normally used in construction in most countries.But I saw some photos that show Iranians are hanging criminals in pubic with cranes instead of gallows.Is it more painful to the dying criminals to the last moment?Do you know why?
they probably didn't have the proper arrangements to carry out the punishment so they used cranes instead of gallows. who knows? but weird really. and it wouldn't be more painful... err... the purpose is to snap the neck... ouch :(
Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
Standard number: GB/T 5031-2008Standard Name: Tower CraneStandard status: currentAlternatives: instead of GB/T 17806-1999; GB/T 17807-1999; GB/T 5031-1994; GB/T 9462-1999This standard specifies the nomenclature, classification and identification, technical requirements, test methods, inspection rules, information identification, packaging, transportation and storage, installation and climbing, and inspection of tower cranes.
Q:(a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
Q:where can i find the xxx video of bob crane?
Bob Crane Tapes
Q:What type of crane done the lift?what type of object was the crane lifting?what was the weight of the load being lifted?
the lift capacity of the Crane is pretty much dictated by the type of crane it is. The largest Gantry / Bridge type is capeable of 1,500 tons.. the largest tower is 100 tons w. a 100meter turning radius. Tracked lattice boom type is 1,600 tons...........(self contained) there's one that will do 4000 tons with modifications including seperate tracks for counterweights
Q:Exactlly what type of bird is a crane?
Crane (bird) From Wikipedia, the free encyclopedia Jump to: navigation, search Cranes Indian Sarus Crane Gruzs antigone antigone Scientific classification Kingdom: Animalia Phylum: Chordata Class: Aves Order: Gruiformes Family: Gruidae Vigors, 1825 Genera Grus Anthropoides Balearica Bugeranus Cranes are large, long-legged and long-necked birds of the order Gruiformes, and family Gruidae. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Most have elaborate and noisy courting displays or dances. While folklore often states that cranes mate for life, recent scientific research indicates that these birds do change mates over the course of their (considerable) lifetimes (Hayes 2005). Some species and/or populations of cranes migrate over long distances, while some do not migrate at all. Cranes are gregarious, forming large flocks where their numbers are sufficient. Most species of cranes are at least threatened, if not critically endangered, within their range. The plight of the Whooping Cranes of North America inspired some of the first US legislation to protect endangered species. They are opportunistic feeders that change their diet according to the season and their own nutrient requirements. They eat a range of items from suitably sized small rodents, fish, amphibians, and insects, to grain, berries, and plants. (The cranberry is so-named for its flowers' resemblence to the neck and head of the crane.) There are representatives of this group on all the continents except Antarctica and South America.
Q:When the tower crane top height is more than meters
Circular of the Ministry of housing, urban and rural construction on Issuing the measures for the safety administration of sub hazardous and sub divisional projectsAnnex No. [2009]87 [Annex two]"More than a certain size of the risk of larger sub sub project scope."
Q:A. Power LinesB. WaterC. FiresD. Overturns
Um, caused by operators who get their training on Yahoo Answers? Overturns are more dangerous to others, a couple years ago a crane killed someone in an apartment across the street from where the crane was working, in a city not far from where I live, but the operator survived. However power lines might be more dangerous to the operator since I suspect they happen more often.
