Q:How to subdue an injured crane?
Thow a blanket over the entire bird, beak and all, and push it to the ground, making sure the beak does not come out. Tuck the feet and legs underneath the bird through the blanket, and grasp the neck through it. Then pick up the birds body in the blanket (carefully, because it has to move its chest to breathe) and place it in an appropriate sized plastic animal carrier or large cardboard box with a lid. That is how you transport a crane to anywhere. You MUST control the head because he will gladly put your eye out with his beak.
Q:calculating psf in regaurdto crawler cranes?
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:the crane and praying mantis/ ba gua?
Well... you seem to have two questions in here. First of all, the crane and praying mantis are both stances used in internal (Weija) and external (Neija) Wing-Chun (Kung-fu). Second, Bagua is one of the internal styles. External styles are more powerful for fighting styles.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
As for the reasons, the main consideration is the actual needs.
Q:In the Pacific NW, what will get rid of Crane Flies in my yard?
If they are indeed crane flies, they have very short lives and will be gone in a short time, and do no harm - so why bother? In any case, I do not see how dolomitic lime would help - their larvae are aquatic, not in the dirt, and the adults do not feed.
Q:Is the crane fight scene in Casino Royale (2006) realistic?
of course its not realistic but it looked great, i just dnt know how they can jump from tht high and land on the other cranes and buildings. james bond was a bit clumsy in tht scene, i reckon tht other black fella was way beta at park-coring
Q:thousand origami cranes?
It's a story about a japanese girl who was diagnosed with leukemia. The story goes, if are diagnosed with leukemia and are able to fold a 1000 paper cranes before you die, you will live. This theory actually works the way horoscopes do. It's not that the making of paper cranes makes you healthy, it has to do with the amount of time it takes. If you survive that long, then you have passed the critical death points and will live anyway, whether you make a thousand of them or not. Plus, it gives you something to do a a healthy, short-term reason to live, which always helps the healing process anyway.
Q:How many meters does the tower crane installation height require expert proof?
The installation, disassembly and jacking of tower cranes must be carried out by experts
Q:How do they put cranes on the top floors when constructing high Sky Scrapers?
The cranes are built in the elevator shafts and moved up as needed during work progress.
