Q:First Summary gets best answer...thanks!: The City is covering itself by shifting the blame form a negligent city inspector to the crane company by charging its owner with Manslaughter Charges. This is typical of civil service personal who forget who they work for (We the People).

Q:How would the environment, habitat, or ecosystem be affected if whooping cranes were extinct?: Are Whooping Cranes Extinct

Q:We had a very large tree removed from beside our house. The crane parked in the driveway and caused four very large depressions and crushed concrete.: No. The driveway is NOT a covered structure. The standard homeowners policy specifically excludes driveways from coverage. But the contractor who brought the crane in, should be responsible for it.

Q:What company makes a good engine crane I can order online?: I would suggest going to Harbor Freight or Oreilley's auto parts... they both should have them at at very reasonable price...if you order online it wouldnt be cost effective due to the shipping and handling added on to the price.

Q:OMG! a phoba of crane flys, and there are 5 on my celling right now!!! What do I do, will the move and fly around eventually? I can't kill them, they are out of my reach, and if they start moving, im runing the %^$ outta my house.Will they die by tommorow? or will they just hang there?: The spiders in your house will kill them and eat them. If you don't have spiders, just wait. They will come in for your crane flies. If you must get rid of them before the spiders do the work, use your vacuum. The crevice tool will suck them up and crush them in the bag. I had one in my house this morning. It was hanging around my east window as the sun was coming up. I used a towel to guide it toward the open patio door. You do need to be up about dawn for this to work.

Q:what is the meaning of the color red in the book The Red Badge of Courage by stephen crane?: Blood or more specifically a bullet wound.

Q:For my science fair project we have to build someething using simple machines, me and my partner decided to do the crane, but we havent been able to find any place that shows intructions on how to build it. If you can please included a step by step plan, the things you will need ( whether or not they are hard to find/ and if so where i might be able to find them ), and your sourcetruely i appreciate this sooo much thankyou in advance everything counts so please make it as detailed as possible and if you know any other sites that show please include thank you sooo much :): you are totally just trying to avoid doing this work by yourself. anybody with two eyes can just look up crane on google and learn how it works. they are super simple just go to the library or something. or better yet go look at a real crane.

Q:how do construction crews put up a crane?: They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.
