- Q:how tower crane extend it heights?
- They okorder /
- Q:I understand the Crane stances and know there are more than one. I am referring to the single leg crane stance. I also know that stances are only used briefly. But I am curious, does this stance have any bunkai applications? Or is it only useful against dodging a kick or preparing to kick?
- In your search for a literal identification of the crane stance, or any physical move for that matter concerning any martial arts is problematic. Although fighting techniques can be identified clearly and others obscure. Instead, try looking at it for its most elementary purpose. That is to say not what can I do with it , but rather what it actually is. By definition any stance is a method of travel to get form place to place, and to enhance your defense and offensive techniques. But not limited to only that. The possibilities then become whatever you discover! As a mater of fact, during any give day the amount of times you use a single leg stance would surprise you. I hope this helps.
- Q:What did Stephen crane contribute to history?
- I think his greatest contribution was The Red Badge of Courage. It was the most ealistic portrayal of a Civil War soldier written at the time; so real, in fact, that veterans swore the had fought alongside him during battle (Crane wasn't even alive during the war).
- Q:My great grandparents' kamon was the crane and I was thinking of getting it as a tattoo for a symbol of my family.However, I'm not sure which it is. I've bought a book on Japanese Crests especially for this, and saw a couple of crane crests but was wondering if there's an origami crane kamon? And if there is, what is the meaning of it?Thank you very much for the help in advance!

- Q:I don't know what the difference is. :(
- an egret is any of several herons and several of which develop milky white plumes during the breeding season,some herons are called egrets. Cranes are a family of large, long-legged and long-necked birds Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes’ necks are a shorter than those of heron.Herons curve their necks into an “S” shape and when they are flying they pull them totally back, while cranes necks’ stick straight out. Cranes also have shorter beaks than herons.
- Q:Is a mobile crane allowed to operate in an inclined plane?
- NO, absolutely not. If the machine is not level, it could fall over. The only way, if it has to be operated on an incline, is if the machine has leveling jacks such as many modern, mobile cranes have.
- Q:I love Bates Motel but I'm just scratching my head like WTF? I'm not being racist but Marion Crane wasn't black in Psycho but okay I'll take it. I guess they may have to find a black actress for Lily Crane. My goodness I don't mean to sound racist but maybe they should've got Maitland McConnell to play Marion. I don't know maybe it's me.What's is your opinion on this?
- I'm alright with it, the Marion Crane character is actually someone Rihanna should play really well, she's a rogue(Marion), and in a modern version, you need to have someone who can do that credibly. Rihanna's more expressive, more aggressive personality will be better than Maitland, Maitland is very much the slasher-bait so far in her movies, Marion Crane has more potential than that.
- Q:vehicle's like car's,truck's etc.need's paper's or document's for regestration or license to used it.what if i mounted or install a crane on it,do i need some paper's or document for regestration or license for the crane?
- I am not sure, but you probably do not need one for a crane perse. Although if you do that, you are basically modifying your current vehicle and you may need documentation for that. To be sure, ask the Land Transportation Office. or visit their site: www.lto .ph/
- Q:You see cranes on the floor which rise about 50 metres, but sometimes, when building high sky scrapers, I see cranes on the 70th floor or the 80th floor. How do they put the the crane so high up there when it can only go up high around 60-70 metres?
- these cranes are self raising. as they need to go higher they raise themselves up on hydraulic jacks and another section is bolted in the gap that is left. i hope this will answer your question
- Q:What is the inspection certificate for tower cranes?
- Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
