- Q:Which one is right? Are there two different kinds? This bird is confusing me.
- Whooping crane, largest bird in North America, named so for its call.
- Q:i am making a wired crane robot to pick and drop a wooden block of about 5*5*10cm dimension. I would like to know wat r the different possible lifting mechanisms by which i can lift the wooden block.Ideas other than the normal claw shaped lifters
- There are different attachments that you can put on the end of your crane to pick up this block. You can make a set of forks (like a forklift) that would slide under the block (block would have to be elevated on a skid). You can pick up this block with a suction cup. You can also pick up the block by clamping the sides of the block by replicating a scissor type mechanism.
- Q:Which kind is better, gantry crane or tower crane?
- Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.
- Q:I used crane to fly me to the korean folk town area. im abck in the station that crane is at but i get up to reach crane. Is there a portal in town or a place i jump to? Please help!!

- Q:I've been wondering about the infamous Crane Stance that many people associate with Martial Arts. Is the Crane Stance a technique that can be used in a fight and strike an opponent effectively without overly exposing yourself to strikes by your opponent? If it is, what are some techniques that can be used out of a Crane Stance?
- As a practitioner of White Crane Boxing, I can tell you that the way the crane stance is demonstrated, is due to lack of knowledge... of course. Firstly, there is no one crane stance. It is not THE crane stance... it is ONE of the crane stances. If there was going to be A crane stance, it would be the Sanchin stance, for it is the foundation stance of the White Crane Fist. Aside from all that, when you perform the single leg crane stance, it is only because there is a technique being executed against an attacker. Yes, it can be used to prepare a kick against an attacker but it has many more applications than that seen on the karate kid and it is not even part of the basic applications for that posture. The technique you saw in the movie was taken from the kata Sanseiru and it is not from a crane stance, it is from Zenkutsu Dachi and it is not merely a skipping front kick as I have heard it called. stslavik - your answer was very good. You have a better understanding than most of the people who answer here. Stances are executions of techniques.
- Q:i have a 100 ton american crawler crane. how do i calculate the psf, for this equipment.
- Not sure what you are asking exactly... Are you saying that you have a crane with a capacity of 100 tons and you want to know the pressure on the soil where the crane is positioned? In this case, you take the capacity (in pounds) plus the weight of the crane (in pounds) then divide their sum by the area of the tracks on the crane (in square feet). This will result in pounds per square foot or psf as you wrote above. These are example estimates, they may not be anywhere near the correct answer, this is simply how to do the calculation. Assumed Capacity 100 ton = 200,000 lbs. Assumed Weight 105 ton = 210,000 lbs. Assumed Area of Track = 200 square feet Note: 1 U.S. ton = 2,000 pounds = 2,000 lbs. 410,000 lbs / 200 square feet = 2,050 psf There's a start, now you just need to find out how much it actually weighs and how long and wide the tracks are to get the area of the track on the ground. I hope that answers the question you were asking.
- Q:Do you believe in the 1000 folded paper cranes give you a wish?What is the entire process in it all?And can they be in another persons hand like if I make 1000 an a few are at my friends possession will it work?
- I believe it too. You just make 1000 paper cranes, and I think that only the victim of the disease is supposed to make it. Oh yea, and you hang the cranes around the victim. This is kind of irrelevant, but once i read a book Sadako and the Thousand Paper Cranes. It's about a girl who tries to make 1000 paper cranes in order to get cured. It's really sad, but that's where I'm getting my info from.
- Q:I read on wikipedia that in recent years, it has become less popular, but they do not mention why. I understand the philosophy of the art and it seems like Machida and Anderson Silva use similar styles. These are 2 of the best fighters in MMA. Can anyone shed some light on this?
- I can't comment on the people you mentioned. What I can say is that White Crane is a good style. BUT, it was never as popular as arts like Goju-ryu, Shotokan, Shito-ryu, and many others. It is curious that Wikipedia would say something like the style is less popular. But then I have always taken what I see on the internet with a grain of salt. Anyone can post any thing they want on the net. That does not make it true.
- Q:If there are cranes by a small pond should there be fish?
- Cranes don't typically eat fish. They mostly eat insects, maybe an unlucky frog. If you're seeing herons or cormorants at this pond regularly, then that's your sign there's fish present. It doesn't take those birds too long to scope out an area for fish, and if there are not any there, the birds will move on. If they are there every day, grab your rod and reel and check it out.
